An 81 year-old woman was referred for the treatment of a 79 mm-diameter short neck abdominal aortic aneurysm with highly tortuous iliac arteries. She was considered at high risk for open repair and not suitable for standard endovascular repair given the short length of the proximal neck. Delay for a manufactured custom-made fenestrated stent-graft was too long given the diameter of the aneurysm. A flexible stent-graft was preferred because of severe iliac tortuosity. Endovascular repair was performed using a physician-modified Anaconda stent-graft with one fenestration for the left renal artery...

PURPOSE: The purpose of this study was to assess the technical feasibility of ultrasound-guided endovascular creation of a percutaneous extraluminal arterial bypass graft without a surgically created arterial anastomosis. MATERIALS AND METHODS: Nine swine were utilized for this IACUC-approved study using a carotid bypass model in swine. Using sonographic guidance, percutaneous access was obtained to the proximal and distal common carotid artery. A self-expanding stent graft was advanced through the proximal carotid access site, tunneled subcutaneously, then advanced through the distal carotid access site, and deployed...

INTRODUCTION: Hereditary Hemorragic Telangiectasia (HHT) is a rare disease consistent in vascular dysplasias affecting different organs. Liver involvement includes telangiectases, arteriovenous shunting, and ischemic cholangitis, and its prevalence ranges from 8 to 31%. Spontaneous pseudo aneurysms have never been reported associated to HHT. Several variations in the origin of the main hepatic artery (MHA) have been described in large radiological series, and can be found in around 4% of general population...

OBJECTIVE: The aim of this study was to report the technical aspects and outcomes of late open conversion (LOC) after endovascular aneurysm repair (EVAR) in a single center by using exclusively infrarenal clamping of the endograft as an alternative to suprarenal or supraceliac aortic clamping. METHODS: A retrospective analysis of EVAR requiring late explantation (>30 days) from January 1996 to October 2016 was performed. Patients' demographics, type of endograft, duration of implantation, reason for removal, extent of stent graft removal, type of reconstruction, 30-day mortality, postoperative complications, and long-term survival were obtained for analysis...

Treatment of thoracic aortic aneurysms constitutes high mortality and morbidity rates despite improvements in surgery, anesthesia, and technology. Endovascular stent grafting may be an alternative therapy with lower risks when compared with conventional techniques. However, sometimes the branches of the aortic arch may require transport to the proximal segments prior to successful thoracic aortic endovascular stent grafting. Atherosclerosis is accounted among the etiology of both aneurysms and occlusive diseases that can coexist in the same patient...

Deep femoral artery pseusoaneurysms (DFAPs) are rare and generally occur after penetrating trauma or surgical procedures. A 36-year old obese man presented with pain in correspondence of the anterior-lateral thigh after 6 months from gunshot wound. Duplex and computed tomography (CT) showed a bilobed right DFAP (maximal diameter 12.9 cm). The patient was managed urgently, under local anaesthesia, by placement in the distal DFA of a Viabahn 8 x 100mm stent-graft (W L Gore & Associates, Inc). The post-operative course was uneventful and the 24-months CT showed regular stent-graft patency and 20 mm DFPA shrinkage...

Type II endoleak is the most frequent procedure-related complication during endovascular aneurysm exclusion. Actually there is little controversy in the management of type I and III endoleak, while type II endoleak still generates conflicting reports about their timing and type of treatment. Currently, the intervention is needed only in case of sac enlargement, but not in case of persistent endoleak alone. We report the case of a 77 year-old man treated with a custom-made branched/fenestrated endograft for a type III thoracoabdominal aortic aneurysm...

PURPOSE: The newly designed unibody AFX endograft system for endovascular aortic aneurysm repair is the only graft with anatomical fixation to the aortic bifurcation in comparison to most other grafts that use the infrarenal neck as the main fixation point. The aim of this study was to assess the preliminary results of the AFX stent-graft system used with infrarenal aortic component and compare them with those obtained in patients treated with a well established endograft of the same material and pure infrarenal fixation as the Gore Excluder...

A 77-year-old male patient presented with a symptomatic, 66-mm pararenal aortic aneurysm. The patient was classified as unsuitable for open surgery due to significant comorbidities. Fenestrated or branched endografts were contraindicated due to the poor iliac access (6 mm diameter). A double Nellix with chimney endovascular aneurysm sealing (ChEVAS) technique was selected to exclude the pararenal aortic aneurysm and to preserve renal arteries and the superior mesenteric artery. Technical preplanning considered the ideal proximal landing zone to be close to the origin of the almost occluded celiac trunk and the distal common iliac arteries as the ideal distal landing zone...

BACKGROUND: The 1-year results of endovascular exclusion of degenerative descending thoracic aortic aneurysms (DTA) with the Valiant Thoracic Stent Graft (Medtronic Vascular, Santa Rosa, Calif) have been previously reported. With long-term follow-up now complete, the 5-year results are reported. METHODS: The VALOR II trial (Evaluation of the Clinical Performance of the Valiant Thoracic Stent Graft System in the Treatment of Descending Thoracic Aneurysms of Degenerative Etiology in Subjects Who Are Candidates for Endovascular Repair) was a prospective, nonrandomized trial of the Valiant Thoracic Stent Graft system in patients with degenerative DTA...

Total endovascular repair of TAAA using branched, fenestrated stent grafts have been performed with promising midterm results. However, severe angulation of the aorta as well as close proximity of the visceral and renal artery ostia pose a significant technical challenge in designing and implanting branched, fenestrated stent grafts. Parallel grafting offers an alternative technique, allowing an urgent, or emergent total endovascular repair of symptomatic, or ruptured TAAA. We describe a technique of 4-vessel incorporation in a total endovascular repair of TAAA, using multilayered parallel endografting via bilateral femoral and unilateral brachial access...

BACKGROUND: Severe aortic tortuosity of the access route often prevents successful complete exclusion of an aneurysm in thoracic endovascular aortic repair (TEVAR). CASE PRESENTATION: We performed antegrade TEVAR on a 79-year-old man with right hemiparesis. We deployed the stent graft from the ascending aorta with a tube graft conduit to treat a descending thoracic aortic aneurysm associated with rickets and multiple comorbidities. Although the application of a ministernotomy diminished the potential advantages of endovascular treatment in view of less invasive surgery, antegrade TEVAR using an ascending aortofemoral through-and-through wire technique was a good option in this patient because a conventional retrograde approach was not feasible due to his severely tortuous aorta...

BACKGROUND: Alternative access for thoracic endovascular aortic repair (TEVAR) has been explored for patients with unsuitable femoral and iliac access, but few cases of transapical access have been described. We report our experience with transapical access for various aortic pathologies. METHODS: We reviewed 6 cases undergoing transapical access for endovascular repair of thoracic aortic pathology between December 2013 and August 2015. Five patients had an aortic arch aneurysm and 1 patient presented with Stanford type A subacute aortic dissection...

BACKGROUND: Diminished pelvic arterial flow as a result of intentional coverage/embolization of internal iliac arteries (IIA) during isolated endovascular common iliac artery aneurysm (CIAA) repair or endovascular repair of abdominal aortic aneurysms (EVAR) may result in symptomatic pelvic ischemia. Although generally well tolerated, in severe cases, pelvic ischemia may manifest as recalcitrant buttock claudication, vasculogenic impotence, or perineal, vesicle, rectal, and/or spinal cord ischemia...

Large celiac artery aneurysms are associated with a high rupture and mortality risk. Traditionally, open surgical repair has been the mainstay of treatment. Endovascular alternatives have been increasingly described, ranging from coil embolization to exclusion with covered stent grafts. However, certain features such as a short wide neck, small vessel diameters, and significant vessel tortuosity can limit these two options. We describe a 75-year-old man with a splenic and celiac trunk aneurysm that was treated using a combination of coil embolization to occlude the outflow artery and aneurysm sac, and an aortic stent graft cuff to block the inflow...

The treatment of choice for aortic coarctation in adults remains open surgical repair. Aortobronchial fistula is a rare but potentially fatal late sequela of surgical correction of isthmic aortic coarctation via the interposition of a graft. The endovascular treatment of aortobronchial fistula is still under discussion because of its high risk for infection, especially if the patient has a history of cardiovascular prosthetic implantation. Patients need close monitoring, most notably those with secondary aortobronchial fistula...

Adam Tanious, Mathew Wooster, Andrew Jung, Peter R Nelson, Martin R Back, Murray L Shames
BACKGROUND: Proximal fixation loss following endovascular aortic aneurysm repair (EVAR) creates a clinical dilemma. Typically, endovascular salvage requires adequate aortic neck below the renal arteries, in cases with no infrarenal neck proximal extension into the paravisceral aorta using parallel grafts provides an alternative to open graft explant. We present our experience at a tertiary care center with endovascular management of proximal fixation loss following EVAR using parallel stent grafting techniques to preserve renal and visceral branches...

BACKGROUND: Abdominal aortic aneurysms (AAAs) are a vascular condition with significant risk attached, particularly if they rupture. It is, therefore, critical to identify and repair these as an elective procedure before they rupture and require emergency surgery. Repair has traditionally been an open surgical technique that required a large incision across the abdomen. Endovascular abdominal aortic aneurysm repairs (EVARs) are now a common alternative. In this procedure, the common femoral artery is exposed via a cut-down approach and a graft introduced to the aneurysm in this way...

INTRODUCTION: Bilateral common iliac artery (CIA) aneurysm (CIAA) is a rare entity. In the past decade, different endovascular approaches have been adopted for patients with several comorbidities or unfit for open repair (OR). Recently, the use of iliac branch stent graft has been proposed, resulting in satisfactory patency rates and decrease in morbidity. Currently, according to instruction for use, the iliac branch stent graft is to be used with aortobi-iliac stent graft conjunction...
