Purpose. Originally developed for treatment of abdominal aortic aneurysms (AAAs), EVAR has been extended to thoracic endovascular aortic graft repair [96]. De très nombreux exemples de phrases traduites contenant "endovascular aneurysm repair" – Dictionnaire français-anglais et moteur de recherche de traductions françaises. Rates of spinal cord injury vary from 0% up to 40%. Instead of an open aneurysm repair in which your chest/abdomen are surgically opened, your surgeon may consider a procedure called an endovascular aneurysm repair (EVAR). ", "Prevention of spinal cord injury during endovascular thoracoabdominal repair", "Endovascular revolution in the aorta: 25 years of a landmark case", "Transfemoral endovascular aortic graft placement", https://en.wikipedia.org/w/index.php?title=Endovascular_aneurysm_repair&oldid=997731383, Creative Commons Attribution-ShareAlike License. © 2020 The Regents of the University of California. The complications of EVAR can be divided into those that are related to the repair procedure and those related to the endograft device. A customized branched endograft has graft limbs that branch off of the main portion of the device to directly provide blood flow to the kidneys, liver, stomach, intestines, and the visceral arteries. The options for repair include traditional open aortic surgery or endovascular repair. Endovascular aneurysm repair(EVAR), is a type of minimally-invasive endovascular surgeryused to treat pathologyof the aorta, most commonly an abdominal aortic aneurysm(AAA). Local or general anesthesia might be used but it … Endovascular aortic aneurysm repair (EVAR) has been shown to reduce blood loss, operative time, length of hospital stay, mortality, and morbidity compared with open surgical repair of infrarenal abdominal aortic aneurysms (AAAs). Periscope: Like a snorkel, a periscope stent-graft provides flow to a visceral vessel, but in retrograde fashion, with the aortic lumen inferior to the main body of the EVAR device. Like many surgical procedures, EVAR has advanced to a more minimally invasive technique, by accessing the femoral arteries percutaneously In percutaneous EVAR (PEVAR), small, sub-centimeter incisions are made over the femoral artery, and endovascular techniques are used to place the device over a wire. Arterial dissection, contrast-induced kidney failure, thromboembolizaton, ischemic colitis, groin hematoma, wound infection, type II endoleaks, myocardial infarction, congestive heart failure, cardiac arrhythmias, respiratory failure. Author information: (1)Mayo Clinic, 200 First Street SW, Rochester, MN 55905, USA. Even in the early days, significant risks were accepted in the understanding that the large open operation was the only option. In addition to a short proximal aortic neck, the neck may be angulated, large in diameter, or shaped like a funnel (conical) where the neck diameter at the top is larger than the neck diameter at the bottom. Local or general anesthesia might be used but it is not a surgery. It usually comprises of a custom-made endograft designed to fit … A hybrid repair strategy offers a reasonable choice for treating such patients. However, medical management is not considered a "fix" for TAA - it just reduces the stresses on the aneurysm. [45] The first clinical series of his device was published from Nottingham in 1994. Endovascular repair of aortic aneurysms (EVAR) has gained widespread acceptance in the treatment of abdominal aortic aneurysms (AAAs). It is usually carried out by a vascular surgeon, interventional radiologist or cardiac surgeon, and occasionally, general surgeon or interventional cardiologist. [40], Spinal cord injury is a devastating complication after aortic surgery, specifically for thoracoabdominal aortic aneurysm repair; severe injury could lead to paraplegia. However, not all aneurysms are suitable for endovascular repair. In 2003, EVAR surpassed open aortic surgery as the most common technique for repair of AAA,[1] and in 2010, EVAR accounted for 78% of all intact AAA repair in the United States.[2]. TCAR (transcarotid artery revascularization) Thromboendarterectomy or Excision of Infected Graf. When used to treat thoracic aorticdisease, the procedure is then specifically termed TEVARfor "thoracic endovascular aortic/aneurysm repair." [22][23][24] Risk of this form of failure is especially elevated in adverse or challenging proximal neck anatomies, where this seal could be compromised by unsuitable geometric fit between the graft and vessel wall, as well as instability of the anatomy. Overview Procedure Details Risks / Benefits Recovery and Outlook Resources. This involves inserting a catheter and guide wire through an artery in your groin or leg. This is not a surgery. During the procedure, the weak section of the aorta is treated to prevent it from tearing. Endovascular aneurysm repair (EVAR) Arteries carry blood away from your heart to the rest of your body. Endovascular coiling is a more recent treatment for brain aneurysms; it has been used in patients since 1991. Endovascular aneurysm repair has serious risks and potential complications. The Annals of Thoracic Surgery, 93(1), 103-109. 27 x 12 bell bottom bridge on the right in a 27 x 12 bell bottom limb of the left common iliac.. PREOPERATIVE DIAGNOSIS: The aortic lumen of the visceral stent is directed superiorly, resembling a snorkel. Women are known to have smaller aortas on average than men, so are potential candidates for AAA treatment at smaller maximum aneurysm diameters than men. Standard EVAR is appropriate for aneurysms that begin below the renal arteries, where there exists an adequate length of normal aorta (the "proximal aortic neck") for reliable attachment of the endograft without leakage of blood around the device ("endoleak"). It is a minimally invasive procedure in which a small incision is made for repairing the aorta. [13] Higher quality evidence suggests that there are no differences in post-repair bleeding complications or haematoma between the two approaches. Originally developed for treatment of abdominal aortic aneurysms (AAAs), EVAR has been extended to thoracic endovascular aortic graft repair [96]. Along with a short proximal aortic neck, necks with any of these characteristics are called "hostile necks" and endovascular repair can be either contraindicated or associated with early late complications of endoleak, or endograft migration, or both. The graft — a woven tube covered by a metal mesh support — is placed at the site of the aneurysm and fastened in place with small hooks or pins. A newer, minimally invasive alternative to traditional open surgery, endovascular aneurysm repair (EVAR), is now being performed regularly for elective AAA repair. Endovascular repair is generally associated with lower morbidity than open repair. [5], Endografts have been used in patients with aortic dissection, noting the extremely complex nature of open surgical repair in these patients. EndoAnchors: Small, helically-shaped devices are screwed through the endograft and into the aortic wall. [8][9][10][11] The procedure can be performed under general, regional (spinal or epidural) or even local anesthesia. The best method to repair an aneurysm depends upon several factors, including the location and shape of the aneurysm as well as the physical condition of the patient. UCSF has a world-renowned program in endovascular surgery, one of the largest and oldest in existence. The advantage of this type of repair is that there is no abdominal surgery. Thoraco-abdominal aortic aneurysms (TAAA) involve the aorta in the chest and abdomen. Lima, B., Roselli, E. E., Soltesz, E. G., Johnston, D. R., Pujara, A. C., Idrees, J., & Svensson, L. G. (2012). However, these are more complex procedures than standard EVAR and may be subject to further complications. It can only be used under the support of an investigational device exemption from the FDA –this trial is referred to as the “TAAA trial”. 31 mm main body place from the patient's left. Endovascular coiling is a procedure performed to block blood flow into an aneurysm (a weakened area in the wall of an artery). A patient's anatomy can be unsuitable for EVAR in several ways. Rayt HS, Sutton AJ, London NJ, Sayers RD, Bown MJ. Your doctor then guides the catheter guide wire to the aortic aneurysm in the abdomen or chest. Some studies have also observed a lower mortality rate with EVAR. Such an aneurysm may rupture, leading to extensive internal bleeding that is frequently fatal. Endovascular grafting is a minimally invasive method to treat an aortic aneurysm. This is called an aneurysm. Vascular surgeons at UCSF have been pioneers in the field of endovascular aneurysm repair for the abdominal and thoracic aorta. The term “endovascular” means “inside blood vessels.” To perform endovascular procedures, vascular surgeons use special technologies and instruments. This is a minimally invasive procedure. These usually happen in the abdominal aorta which is the vessel that leads from the heart, through the tummy (abdomen) to the rest of the body and is called an abdominal aortic aneurysm (AAA). [46] The first endovascular repair of a ruptured abdominal aortic aneurysm was also reported from Nottingham in 1994.[47]. When used to treat thoracic aortic disease, the procedure is then specifically termed TEVAR for "thoracic endovascular aortic/aneurysm repair." Expanded SVS 72% Endovascular Aneurysm Repair (EVAR) 66% open Thus, even when using the most liberal guidelines, 27% of EVAR and 33% of … Depending on the aortic anatomy, they may require further intervention to treat. Durability and problems such as 'endoleaks' may require careful surveillance and adjuvant procedures to ensure success of the EVAR or EVAR/hybrid procedure. Bowel ischaemia after endovascular aneurysm repair Vasa. Summary Background Data: Several studies have demonstrated a reduction of T2EL by IMA embolization before EVAR. Dr. Juan C. Parodi introduced the minimally-invasive endovascular aneurysm repair (EVAR) to the world and performed the first successful endovascular repair of an abdominal aortic aneurysm on 7 September 1990 in Buenos Aires on a friend of Carlos Menem, the then President of Argentina. Repair of Arterial Aneurysm. The aortic arch is transected and the stent graft device is delivered in an ante-grade fashion in the descending aorta. A thoracic aortic aneurysm is a bulge in the aorta which can cause the aorta's diameter to balloon to several times its normal size. Endovascular aneurysm repair involves inserting a graft within the aneurysm through small groin incisions using X-rays to guide the graft into place. Type IV - Leakage through the graft wall due to the quality (porosity) of the graft material. In hybrid procedures, the endograft is positioned over major aortic branches. On occasion, there is inadequate length or quality of the proximal or distal aortic neck. 2 2 Liverpool Vascular and Endovascular Service, Royal Liverpool University Hospital, Liverpool, United Kingdom. Vascular surgeons at UCSF have been pioneers in the field of endovascular aneurysm repair for the abdominal and thoracic aorta. Type II - Retrograde flow to the aneurysm sac from branches such as the. [34][35] These EndoAnchors may also be used to treat identified leaks between the graft and proximal neck.[36][37][38]. Then, using an x-ray to see the artery, the surgeon threads the graft (also called a stent graft) into the aorta to the aneurysm. A newer, minimally invasive alternative to traditional open surgery, endovascular aneurysm repair (EVAR), is now being performed regularly for elective AAA repair. Repair is also warranted for aneurysms that rapidly enlarge or those that have been the source of emboli (debris from the aneurysm that dislodge and travel into other arteries). Most commonly, in an infrarenal aneurysm, a potential EVAR candidate lacks adequate length of normal-diameter aorta between the aneurysm and the takeoff of the renal arteries, the "infra-renal neck". Vascular Ultrasound (venous, arterial, carotid, abdominal, renal artery) Venous Exams of the Legs Endovascular abdominal aortic aneurysm (AAA) repair is surgery to repair a widened area in your aorta. Endovascular aneurysm repair involves the transfemoral or transiliac placement of a endograft within the aneurysm, with the aim of completely excluding the aneurysm sac from the circulation. These procedures require only … The term “endovascular” means “inside blood vessels.”. Frank Veith, Michael Marin, Juan Parodi and Claudio Schonholz at Montefiore Medical Center affiliated with Albert Einstein College of Medicine. If a patient has calcified or narrow femoral arteries that prohibit the introduction of the endograft transfemorally, an iliac conduit may be used. Endovascular repair of aneurysms does not require a large incision and has a substantially shorter recovery than the conventional open surgical approach. As immunosuppressive medications are known to increase the rate of aneurysm growth, transplant candidates are AAA repair candidates at smaller maximum aneurysm diameters than the general population. After a few years the survival after repair is similar with EVAR or open surgery. Newer, improved technology may reduce the need for such secondary procedures. Endovascular repair is a procedure to fix an aortic aneurysm in the abdomen. [29][30][31], An approach that directly augments the fixation and sealing between the graft and aorta to mimic the stability of a surgical anastomosis is EndoAnchoring. At this point, an aneurysm is at risk of rupturing and causing  potentially fatal bleeding, just as a balloon will pop when blown up too much. Endovascular aneurysm repair (EVAR), is a type of minimally-invasive endovascular surgery used to treat pathology of the aorta, most commonly an abdominal aortic aneurysm (AAA). One example in the treatment of thoracic aortic disease is revascularization of the left common carotid artery and/or the left subclavian artery from the innominate artery or the right common carotid artery to allow treatment of a thoracic aortic aneurysm that encroaches proximally into the aortic arch. Endovascular procedures aim to reduce the morbidity and mortality of treating arterial disease in a patient population that is increasingly older and less fit than when major open repairs were developed and popularized. Our physicians have special board certification in vascular diagnosis as well as endovascular repair and treatment procedures from the American Board of Radiology. The advantage of this type of repair is that there is no abdominal surgery. The endograft acts as an artificial lumen for blood to flow through, protecting the surrounding aneurysm sac. This is called an aneurysm. Type 2 leaks are common and often can be left untreated unless the aneurysm sac continues to expand after EVAR. The graft is then expanded inside the aorta and fastened in place to form a stable channel for blood flow. A branched endograft has graft limbs that branch off of the main portion of the device to directly provide blood flow to the kidneys or the visceral arteries. Endovascular stent graft repair is designed to help prevent an aneurysm from bursting. EndoAnchors have been used successfully to treat endoleaks and, in concert with an aortic extension endograft, to treat migration of the original endograft. For example, a myocardial infarction that occurs immediately after the repair is normally related to the procedure and not the device. Advanced EVAR requires repair of a thoracoabdominal aortic aneurysm, or one close to the kidney arteries, often using a custom-made graft with branches or openings (fenestrations) to re-attach important arteries of the thoracic and/or the abdominal aorta. The abdominal aneurysm extends down to the common iliac arteries in about 25%-30% of patients. (Refer to "Description" below.) 23 mm IBE on the right with a 12 x 7 iliac branch on the right into the internal iliac. Endovascular repair of aortic aneurysm in patients physically ineligible for open repair. Since the first endografts were placed two decades ago, many changes have been made in graft design, operative technique, and management of complications. Setting: Patients were recruited from 38 … In endovascular repair, doctors attach a synthetic graft to the end of a thin tube (catheter) that's inserted through an artery in your leg and threaded up into your aorta. The aorta is the large artery that carries blood to your belly, pelvis, and legs. Open abdominal aortic aneurysm (AAA) repair has been performed successfully for decades. 2018 Jun;47(4):273-277. doi: 10.1024/0301-1526/a000698. In these cases a fenestrated endograft may be useful, where the attachment of the endograft to the aorta may be placed above the renal arteries with each fenestration opposite a renal artery so that blood flow to the kidneys is maintained. The procedure is carried out in a sterile environment under fluoroscopic guidance. Instead of an open aneurysm repair in which your chest and abdomen are surgically opened, your surgeon may consider a procedure called an endovascular aneurysm repair (EVAR). A "reverse frozen elephant trunk repair" is shown to be particularly effective.[19]. This study was performed using population-based data to determine the changing trends in the techniques for abdominal aortic aneurysm (AAA) repair in the state of Illinois during the past 9 years and to examine the extent to which endovascular aneurysm repair (EVAR) has influenced overall AAA management. This article describes how EVAR can treat a potentially life-threatening AAA and what nurses can do to ensure a successful outcome. Perdikides et al "Primary EndoAnchoring in the Endovascular Repair of Abdominal Aortic Aneurysms With an Unfavorable Neck". This is because head vessels of the aortic arch supplying blood to the brain cannot be covered and for this reason there in often an inadequate landing zone for stent graft delivery. You may have other treatment options, including open surgery. A major cause of complications in EVAR is the failure of the seal between the proximal, infra-renal aneurysm neck and the endovascular graft. Endovascular repair of infrarenal abdominal aortic aneurysms (EVARs) has revolutionized the treatment of aortic aneurysms, with over half of elective abdominal aortic aneurysm repairs performed endoluminally each year. By 2003, 4 devices were on the market in the United States. In patients with thoracic aortic disease involving the arch and descending aorta, it is not always possible to perform a completely endovascular repair. Endovascular aneurysm repair (EVAR) grafting holds the promise of effective and durable repair, improved morbidity and mortality relative to surgical correction, and reduced hospital costs [105–112]. Endovascular aneurysm repair (EVAR) is a procedure to fix an aortic aneurysm in the abdomen. Endovascular Aneurysm Repair Market Global Analysis, Demand, Share, Insights, Size, Growth, Demand Forecast to 2026 Sitemap The global endovascular aneurysm repair market is expected to rise with an impressive CAGR and generate the highest revenue by 2026. Endovascular repair for thoracic aortic aneurysm. Endovascular aneurysm repair (EVAR) is a preferred treatment option for aortic aneurysm given its advantages over open surgery. Endovascular aneurysm repair (EVAR), is a type of minimally-invasive endovascular surgery used to treat pathology of the aorta, most commonly an abdominal aortic aneurysm (AAA). The endograft is anchored in place by self expanding or balloon expandable stents, which may support all or part of the graft. Endovascular stent graft repair is designed to help prevent an aneurysm from bursting. This is a bulge in the wall of the large artery below your heart that is at risk for rupture. Roselli, E. E., Qureshi, A., Idrees, J., Lima, B., Greenberg, R. K., Svensson, L. G., & Pettersson, G. (2012). Thoracic endovascular aortic repair (TEVAR) has emerged as the surgical treatment of choice for patients with thoracic aortic aneurysm. Endovascular Repair of Abdominal Aortic Aneurysm (EVAR) Coverage, Coding and Reimbursement Overview — Hospital (Facility) Inpatient 2019 Edition — All Reimbursement Amounts are Listed at National Unadjusted Medicare Rates and Do Not Include the 2% Sequestration Reduction United Kingdom EVAR Trial Investigators", "Helical Endostaples Enhance Endograft Fixation in an Experimental Model Using Human Cadaveric Aortas", "Use of endostaples to secure migrated endografts and proximal cuffs after failed endovascular abdominal aortic aneurysm repair", "Aortic graft infection: is there a place for partial graft removal? Endovascular aneurysm repair involves inserting a graft within the aneurysm through small groin incisions using X-rays to guide the graft into place. In uncomplicated type B aortic dissection, TEVAR does not seem either to improve or compromise 2-year survival and adverse event rates. Surgery is currently the standard treatment for ascending thoracic aortic aneurysm (ATAA). The diagram above shows the steps involved in inserting the device. 2010; 362:1872–1880. S W Yusuf, S C Whitaker, TAM Chuter, PW Wenham, BR Hopkinson EMERGENCY ENDOVASCULAR ABDOMINAL AORTIC ANEURYSM REPAIR (letter) Lancet 1994; 344: 1645, "Impact of hospital market competition on endovascular aneurysm repair adoption and outcomes", "Comparison of Long-term Survival After Open vs Endovascular Repair of Intact Abdominal Aortic Aneurysm Among Medicare Beneficiaries", "Randomized comparison of strategies for type B aortic dissection: the INvestigation of STEnt Grafts in Aortic Dissection (INSTEAD) trial", "Editor's choice - Management of descending thoracic aorta diseases: Clinical practice guidelines of the European Society of Vascular Surgery (ESVS)", 1983/6273178d-f3ec-42f0-a26c-fd8ffdb5e82f, "National Vascular Registry - 2018 Annual Report", "Endovascular aortic aneurysm repair (EVAR)", "Endovascular aortic repair: first twenty years", "Totally percutaneous versus surgical cut-down femoral artery access for elective bifurcated abdominal endovascular aneurysm repair", "Hybrid repair of Kommerell diverticulum", "Repair of retrograde ascending dissection after descending stent grafting", "Endovascular versus open repair of abdominal aortic aneurysm. One solution, however, is a hybrid repair, which combines an open surgical bypass with EVAR or TEVAR. The aortic arch is subsequently reconstructed and the proximal portion of the stent graft device is then directly sutured into the surgical graft. Endovascular Aneurysm Repair Market Overview: Global Endovascular Aneurysm Repair (Evar) Market was valued at $2,327 million in 2016, and is expected to reach at $3,580 million by 2023, registering a CAGR of 6.2% from 2017 to 2023. Before people are deemed to be a suitable candidate for this treatment, they have to go through a rigorous set of tests. Dr. Timothy Chuter pioneered this approach, with a completely endovascular solution. Ann Vasc Surg 2013. Crossref Medline Google Scholar; 26. The aorta is the large blood vessel (artery) that carries blood from the heart through the belly to the rest of the body. Predictive factors include extent of coverage, hypogastric artery occlusion, prior aortic repair and perioperative hypotension. Brain aneurysm repair is a surgical procedure used to treat a bulging blood vessel in the brain that’s at risk of rupturing or tearing open. The EVAR1 trial of open compared with endovascular repair in 1252 patients with intact abdominal aortic aneurysm recently reported 15 year follow-up data.6 The early advantage of endovascular repair had disappeared by six months, and from eight years onward the open repair group had better survival. The Annals of Thoracic Surgery, 94(3), 751-758. Endovascular abdominal aortic aneurysm (AAA) repair is surgery to repair a widened area in your aorta. Varicose Vein Procedures. The procedure involves the placement of an expandable stent graft within the aorta to treat aortic disease without operating directly on the aorta. Endograft migration, aneurysm rupture, graft limb stenosis/kinking, type I/III/IV endoleaks, stent graft thrombosis, or infection. If you do not want open chest or abdominal repair, your doctor may suggest endovascular repair. You may be eligible for endovascular stent grafting if your thoracic aneurysm has not ruptured and the aneurysm is 5 centimeters or more in size. An endovascular repair of a TAAA is only possible if blood flow to these critical arteries is preserved. The catheter is threaded to the abdominal aorta, and the stent graft is released from the catheter. Endovascular aneurysm repair (EVAR) is a procedure to fix an aortic aneurysm in the abdomen. It's called endovascular because a doctor repairs the aneurysm from the inside of the damaged blood vessel (the aorta). Due to the expense associated with EVAR stent graft devices and their specificity to human aortic anatomy, EVAR is not used in other animals. N Engl J Med. As such, major branch arteries to the head, arms, spinal cord, intestines and kidneys may originate from the aneurysm. PROCEDURE: Endovascular repair of aortobiiliac aneurysm with WL Gore iliac branch device. Just like a balloon, the aneurysm enlarges, stretching the walls of the artery thinner which compromises the artery wall's ability to stretch any further. Alternatively, a specially designed endograft, (an iliac branch device) can be used to preserve flow to the internal iliac arteries. In particular the calibre/tortuosity of the iliac arteries and the relationship of the neck of the aneurysm to the renal arteries are important determinants of whether the aneurysm is amenable to endoluminal repair. Endovascular Repair of Thoracic Aortic Aneurysms Menu. seeking to develop state-of-the-art endovascular devices to advance the treatment of aortic aneurysms. Anatomical constraints limit the use of EVAR in 30 to 40 percent of patients, because of short necks, excessive angulation, or frank aneurysm involvement of aortic side branches such as supra-aortic … That is not the case in most patients today. The aorta is the large artery that carries blood to your belly, pelvis, and legs. A commonly used hybrid repair procedure is the "frozen elephant trunk repair". CT Angiography (CTA) imaging has in particular made a key contribution to planning, success, durability in this complex area of vascular surgery. While such a position would normally cause problems from disruption of blood flow to the covered branches (renal, visceral, or branches to the head or arms), the prior placement of bypass grafts to these critical vessels allowed deployment of the endograft at a level that would otherwise not be possible. Stents: Large bare-metal stents have been used to treat proximal endoleaks, as have aortic extension cuffs to treat endograft migration. An aortic aneurysm is a bulging, dilation or ballooning in the wall of a blood vessel, usually an artery, that is due to weakness or degeneration that develops in a portion of the artery wall. X-rays and ultrasound imaging help the doctor make sure that the stent graft is properly placed and excluding blood flow to your abdominal aortic aneurysm. Performed by Dr. Studies have reported successful use of hybrid techniques for treating Kommerell Diverticulum[16] and descending aneurysms in patients with previous coarctation repairs. This article describes how EVAR can treat a potentially life-threatening AAA and what nurses can do to ensure a successful outcome. BACKGROUND: Endovascular aortic aneurysm repair (EVAR) is the preferred first-line treatment for abdominal aortic aneurysms. These "extra-anatomic bypasses" can be performed without an invasive thoracotomy. The current phase of this study began in 2005, using an industry-made version of the multi-branched stent-graft to treat over 100 patients so far. The endograft is then introduced into the aorta through the conduit. This is a bulge in the wall of the large artery below your heart that is at risk for rupture. In anatomic position, blood flows superiorly through a chimney-stent-graft into the great vessel, just as smoke flows up a chimney. Instead of an open aneurysm repair in which your chest and abdomen are surgically opened, your surgeon may consider a procedure called an endovascular aneurysm repair (EVAR). Local or general anesthesia might be used. This is typically a piece of PTFE that is sewn directly to the iliac arteries, which are exposed via an open retroperitoneal approach. Endovascular repair of Abdominal Aortic Aneurysm, performed by an interventional radiologist in conjunction with a vascular surgeon, is a minimally invasive technique using imaging guidance to place a graft inside the patient’s aorta, effectively sealing off the aneurysm.
