endovascular graft exclusion

PURPOSE: To describe the endovascular treatment of a symptomatic juxtarenal abdominal aortic aneurysm (JAAA) using a combination of endoanchors (Heli-FX EndoAnchor, Medtronic, Minneapolis, Minnesota) and a physician-modified single-fenestrated endograft. TECHNIQUE: An 85 year-old patient unfit for open aortic repair presented for a symptomatic JAAA, characterized by an infrarenal neck with 0.6 cm in length and 23 mm in diameter. A 28 mm-diameter Endurant aortic cuff (Medtronic, Minneapolis, Minnesota) was modified with a single fenestration for the left renal artery (LRA) and diameter-reducing tie, then re-sheathed and deployed...

PURPOSE: Comparison of hybrid and total endovascular aortic arch repair at two tertiary vascular surgery centers. MATERIALS AND METHODS: Consecutive patients undergoing hybrid (HG) or total endovascular (TEG) total aortic arch repair for aneurysms or dissections were included (2008-2022). Primary outcome measure was 30-day mortality. Secondary outcomes were major complications, technical success (defined as absence of surgical conversion/mortality, high-flow endoleaks or branch/limb occlusion), clinical success (defined as absence of disabling clinical sequelae), late and aortic-related mortality/reinterventions, freedom from endoleaks, aortic diameter growth > 5 mm, graft migration and supra-aortic trunks (SAT) patency...

OBJECTIVE: We assessed the suitability of two triple branch arch devices (aBranch) (Terumo aortic and Cook Medical) and a balloon-expandable covered stent (VBX, W. L. Gore & Associates, Johnson & Johnson) to incorporate the brachiocephalic trunk (BCT) in a cohort previously treated with hybrid thoracic endovascular repair (TEVAR). METHODS: This is a single-center, retrospective, all-comers, preclinical suitability study. We conducted an analysis of preoperative computed tomography scans in surgical patients between 1999 and 2022 in a single vascular surgery unit...

BACKGROUND: Behcet's disease is a multi-systemic inflammatory disorder. Paravalvular leakage and aortic pseudoaneurysm are rare in patients with Behcet's disease after aortic root replacement. Complicated post-operative infective endocarditis can make the treatment more difficult. We applied a flanged Bentall procedure to treat one such case. CASE SUMMARY: A 27-year-old man with aortic regurgitation and Behcet's disease underwent aortic root replacement. Post-operative electrocardiogram showed a complete atrioventricular block...

A 62-year-old woman with abdominal pain was diagnosed with a splenic artery aneurysm (SAA) and an anatomical variant in the splenic artery (SA) arising from the superior mesenteric artery (SMA) as its first branch. To treat the SAA, the draining artery and a small branch of the SAA were embolized, and then small-diameter stent grafts were deployed from SMA orifice, covering the aberrant origin of the SA and preserving the second branch of SMA. Intraoperative angiography confirmed successful exclusion of the SAA without endoleak or arterial dissection...

OBJECTIVE: To report on the outcomes of patients undergoing an iliac branch device implantation after previous open or endovascular aorto-biliac repair, using exclusively femoral access for catheterization and delivery of the covering stent to the hypogastric artery. METHODS: Single-center retrospective study in which all patients in whom an iliac branch device was implanted after previous open or endovascular aorto-biliac repair were identified. Patients in whom the hypogastric artery catheterization and delivery of the bridging cover stent were achieved via exclusive femoral access were included...

OBJECTIVES: The management of type 1B endoleaks following endovascular aortic aneurysm repair (EVAR) can be challenging. The Heli-FX Endoanchor system effectively treats proximal type 1A endoleaks but has not been used for type 1B common iliac artery endoleaks. This study demonstrates that it is both safe and effective in being used in the common iliac artery (CIA) limb of an EVAR. METHODS: A retrospective review of patients identified through coding and medical records was performed to extract information on demographics, aneurysmal features, operative features, and postoperative outcomes...

OBJECTIVE: Complex middle cerebral artery (MCA) aneurysms incorporating parent or branching vessels are often not amenable to standard microsurgical clipping or endovascular embolization treatments. We aim to discuss the treatment of such aneurysms via a combination of surgical revascularization and aneurysm exclusion based on our institutional experience. METHODS: Thirty-four patients with complex MCA aneurysms were treated with bypass and aneurysm occlusion, 5 with surgical clipping or wrapping only, and 1 with aneurysm excision and primary reanastomosis...

BACKGROUND: Stent graft-induced new entry (SINE), defined as the stent graft-induced formation of a new entry point for blood to enter an area, is increasingly being observed after thoracic endovascular aortic repair (TEVAR) for Stanford type B aortic dissection worldwide. We herein describe a case of Stanford type A aortic dissection due to proximal SINE after TEVAR for Stanford type B dissection. CASE PRESENTATION: This case involved a 58-year-old man with type A aortic dissection due to SINE...

Superior mesenteric artery aneurysms are rare and associated with high mortality rates in cases of rupture. Current Society for Vascular Surgery guidelines recommend treatment of all superior mesenteric artery aneurysms regardless of size. A 53-year-old woman who was admitted for abdominal pain was found with a 14-cm, ruptured superior mesenteric artery branch aneurysm. Endovascular approach was performed with microvascular plug embolization of a feeding branch and aneurysm sac exclusion with a stent graft...

PURPOSE: To evaluate endovascular popliteal artery aneurysm repair using a an "off-label" abdominal endograft limb-module with nitinol-ring structure. MATERIALS AND METHODS: Retrospective observational study of 14 popliteal artery aneurysms in 12 male patients (mean age 76 years and median ASA grade 3) treated electively using the Anaconda™ endograft limb (Terumo Aortic) at a single teaching hospital. Eight limbs were treated percutaneously and 6 limbs required surgical arterial exposure...

PURPOSE: To demonstrate the feasibility of the modification to preserve intercostal arteries of the t-Branch Endograft (Cook Medical, Bloomington, IN) in an urgent setting, associated with a less invasive approach for branch incorporation from percutaneous femoral access with steerable sheaths. TECHNIQUE: A 73-year-old female patient presented at our institution with intense abdominal pain. Angiotomography showed a 50-mm juxtarenal aortic aneurysm, with no signs of rupture...

OBJECTIVES: to evaluate the suitability of a subclavian unibody single branch endograft among patients treated with Thoracic Endovascular Aortic Repair in landing zone 2. METHODS: pre-clinical, single-center, real-world, all-comers, retrospective cohort study.Patients treated with Thoracic Endovascular Aortic Repair in landing zone 2 with an available pre-operative computed tomography angiography were included. The primary outcome was the anatomical feasibility of the Castor endograft in patients receiving endovascular treatment in landing zone 2 between 1999 and 2022...

OBJECTIVE: The implementation of thoracic endovascular aortic repair (TEVAR) in patients with type A aortic dissection has been strictly constrained due to the pulsatile movement and distensibility and the insufficient length of landing zones on ascending aorta. The most prevalent anatomical limitation is the insufficient length of proximal and distal landing zones. We propose a modularly designed Endo-Bentall stent-graft system to broaden the scope of TEVAR in the ascending aorta by covering intimal tears in the aortic root and ascending aorta, and reconstructing coronary arteries...

UNLABELLED: A double secondary aortoenteric fistula (AEF) occurs in a patient who has had significant aortic surgery and is characterized by a direct connection between the gastrointestinal (GI) tract and the aorta at two separate sites. IMPORTANCE: During aortoc reconstructive surgery, the patient may present with a variety of unusual complaints, including fever and GI bleeding. These symptoms are indicative of problems, including the development of an aortoentric fistula, particularly when there is a double secondary fistula...

BACKGROUND: Isolated iliac artery aneurysm (IIAA) is an uncommon finding. It, accounts for 0.03% of all patients and 2% of all abdominal aneurysm. Endovascular approach represents the treatment of choice for most patients with IIAA. We reported our experience on iliac aneurysm with no proximal landing zone by simultaneous aortoiliac kissing endovascular (S.A.K.E.) covered stenting. METHODS: This is a retrospective analysis of nine consecutive patients with IIAA with no proximal landing zone, who underwent endovascular kissing covered stenting (Gore® Viabahn® VBX) The median aneurysm diameter was 4...

Background and Objectives : Persistent sciatic artery (PSA) is a rare congenital vascular anomaly that is often asymptomatic, but can be associated with aneurysm formation and potential complications, such as thromboembolism or aneurysm rupture in some cases. We present a case of a 75-year-old woman with a symptomatic thrombus-containing aneurysm of the left PSA. Materials and Methods : The treatment of the PSA aneurysm involved a successful hybrid approach, which included open surgical bypass and endovascular embolization...

BACKGOUND: The number of endovascular abdominal aortic aneurysm repairs (EVARs) has surpassed the number of open surgical repair of AAAs worldwide with a great variety of endografts being available. The aim of this study is to conduct a systematic review of the literature and meta-analysis of studies reporting patients with infrarenal abdominal aortic aneurysm (AAA) subjected to EVAR with the Anaconda endograft. METHODS: We performed a systematic review of multiple electronic databases for studies including patients with infrarenal AAA who were subjected to elective EVAR with Anaconda endograft exclusively...

PURPOSE: Ruptured mycotic pararenal aortic aneurysms are rare and serious condition that requires prompt treatment. Open surgery with aortic resection and in-situ or extra-anatomic reconstruction is the standard treatment. The aim of this technical note is to report urgent endovascular treatment using a readily available custom-made device (created for another patient), with a back-table modification using pericardium patch and a new fenestration. TECHNIQUE: In preoperative measurements on centerline-based workstation, aortic diameter in proximal and distal landing zone and target vessel position matched the measurements of graft plan of custom-made device (CMD) besides left renal artery...

OBJECTIVE: The main objective of this study is to present the experience of 2 centers undertaking total percutaneous aortic arch-branched graft endovascular repair using combination of femoral and axillary routes. The report summarizes the procedural steps, outcomes achieved, and the benefits of this approach, which eliminates the need for direct open surgical exposure of the carotid, subclavian, or axillary arteries, thereby reducing the unnecessary associated surgical risks. METHODS: Retrospectively collected data of 18 consecutive patients (15M:3F) undergoing aortic arch endovascular repair using a branched device between February 2021 and June 2022 at 2 aortic units...
