Spinal cord ischemia(SCI) has been devastating complication of endovascular thoracic and thoracoabdominal aortic repair. Spinal cord blood supply arises from not only segmental artery, subclavian artery, hypogastric artery and these branches, but also perivertebral vasculature and paravertebral muscle and small arterial network, and risk factors of SCI were multifactorial. There are several adjuncts/strategies which are utilized to minimize the incidence of SCI: cerebrospinal fluid drainage, perioperative management of high mean arterial pressure, intraoperative evoked potential monitoring, and staged thoracoabdominal aortic repair...

Open aortic aneurysm repair in the setting of bilateral hypogastric aneurysms is technically challenging. We present a novel technique for open surgical repair for bilateral hypogastric aneurysms using the Gore hybrid vascular graft (GVHG; W. L. Gore and Associates Inc, Flagstaff, Arizona). The GVHG is an expanded polytetrafluoroethylene graft with a nitinol stent at 1 end designed for hemodialysis access. The GVHG has been also been used for aortic debranching and treatment of occlusive disease. We describe the first report using GVHG to repair hypogastric aneurysms...

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...

OBJECTIVE: During endovascular aneurysm repair (EVAR), severely tortuous aortoiliac anatomy can alter the deployment and conformability of the endograft. The accuracy of treatment length measurements is commonly recognized to be affected by severe tortuosity. However, the exact mechanism of the postintervention length discrepancy is poorly understood. The objective of this study was to determine the mechanism of how severe aortoiliac tortuosity influences the endograft and native aorta during EVAR and its impact on the distal sealing zone...

Endovascular aneurysm repair (EVAR) has revolutionized the treatment of abdominal aortic aneurysm (AAA). However, persistent AAA sac endoleak following EVAR can result in sac diameter increase requiring re-intervention in up to one-third of cases and even result in aneurysm rupture. In this case review, we summarize and detail endovascular re-interventions for each type of endoleak. We also detail specific options including stent-graft relining for indeterminate, Type III, and Type IV endoleaks and perigraft arterial sac embolization to induce thrombosis and resolve acute Type I, II, or III endoleaks...

PURPOSE: Hypogastric artery (HA) revascularization during endovascular aneurysm repair (EVAR) is still open to debate. Moreover, exclusion-related complication rates reported in literature are not negligible. The aim of this study is to present and analyze the outcomes in patients undergoing EVAR with exclusion of 1 or both HAs at our academic center. METHODS: We retrospectively reviewed our results in patients submitted to EVAR and needing HA exclusion, in terms of perioperative (30-day) and follow-up rates of intestinal and spinal cord ischemia, buttock claudication, buttock skin necrosis, and sexual dysfunction...

BACKGROUND: Bowel ischemia is a rare but devastating complication after abdominal aortic aneurysm (AAA) repair. Its rarity has prohibited extensive risk-factor analysis, particularly since the widespread adoption of endovascular AAA repair (EVAR); therefore, this study assessed the incidence of postoperative bowel ischemia after AAA repair in the endovascular era and identified risk factors for its occurrence. METHODS: All patients undergoing intact or ruptured AAA repair in the Vascular Study Group of New England (VSGNE) between January 2003 and November 2014 were included...

Use of endovascular means is gaining ever greater acceptance in the treatment of aorto-iliac aneurysms. Especially, the treatment of patients with common iliac aneurysms (CIAs) may be very challenging due to the complexity of the underlying disease with often involvement of the hypogastric artery. Additionally, the variety of endovascular therapeutic options such as the use of iliac branch devices, parallel grafts, the bell-bottom technique or coil embolization of the hypogastric artery and overstenting of the origin represents significant limitation regarding the presentation of a clear and robust endovascular therapeutic algorithm...

BACKGROUND: Concomitant procedures during endovascular aneurysm repair (EVAR) of an abdominal aortic aneurysm are performed to facilitate endograft delivery, to simultaneously treat unrelated conditions, or to resolve intraoperative pitfalls. The frequency and perioperative impact of these procedures are not well described. This study aimed to assess the frequency and perioperative impact of various concomitant procedures performed at the time of EVAR. METHODS: We included all elective EVARs in the Vascular Study Group of New England between January 2003 and November 2014 and identified those with and those without concomitant procedures...
