OBJECTIVES To report a rare case of delayed Type IIIb endoleak secondary to fabric tear following implantation of a Medtronic Talent endovascular device. METHODS A 83-year old gentleman underwent elective endovascular aneurysm repair for infrarenal abdominal aortic aneurysm with a Medtronic bifurcated stent graft in 2008. RESULTS Seven years after the initial repair, imaging surveillance re...

Only a few cases of endoleak following conventional abdominal aortic aneurysm repair have been reported. We treated a patient with a type I endoleak-like phenomenon occuring 12 years after conventional abdominal aortic aneurysm repair. Computed tomography demonstrated dilation of the surgically replaced, once-shrunken aneurysm sac to a diameter of 3.5 cm. Thrombus was identified between the gra...

conclusions considering the unique construct of the powerlink stents, this is thought to represent aneurysmal degeneration of the outer fabric material from the metal struts and may potentially pressurize the excluded sac with risk for rupture. case presentation a 65-year-old woman who had endovascular aortic repair (evar) of an abdominal aortic aneurysm with endologix powerlink system develope...

OBJECTIVE Hostile infrarenal neck characteristics are associated with complications such as type Ia endoleak after endovascular aneurysm repair. Aortic neck angulation has been identified as one such characteristic, but its association with complications has not been uniform between studies. Neck angulation assumes triangular oversimplification of the aortic trajectory, which may explain confli...

Endovascular repair has been used over a decade as a treatment of abdominal aortic aneurysm, and has become a widely accepted treatment method with a low rate of perioperative complications. Endoleak, perigraft blood flow outside endograft but within aneurysmsac, has been intensively studied during the last 10 years of endovascular aneurysm repair (EVR). The natural history of aneurysms with en...

Endovascular aortic aneurysm repair (EVAR) is a predominant surgical procedure to reduce the risk of aneurysm rupture in abdominal aortic aneurysm (AAA) patients. Endoleak formation, which eventually requires additional surgical reoperation, is a major EVAR complication. Understanding the etiology and evolution of endoleak from the hemodynamic perspective is crucial to advancing the current pos...

Endovascular aneurysm repair (EVAR) of abdominal aortic aneurysms (AAA) was introduced 20 years ago as a minimally invasive prophylactic procedure to prevent aneurysm rupture. However, rupture after EVAR has been reported and is associated with a high mortality. Rupture after successful EVAR is usually preceded by endograft-related complications, such as type I endoleak and stentgraft migration...

OBJECTIVES To present results from the first 100 patients treated with the new C3 Gore Excluder stent-graft in a single institution. METHODS All patients treated with the C3 Excluder stent-graft between August 2010 and July 2013 in our institution were included. Patient demographics, treatment indication, need for intraoperative stent-graft repositioning, immediate technical success, survival...

PURPOSE Type I endoleak is known to be associated with sac enlargement and occasional rupture, therefore, the treatment of type I endoleak is recommended at the time of diagnosis. The aim of this study was to identify the significance of early type I endoleak found on completion angiography. METHODS Between January 2000 and December 2012, a total of 86 patients underwent endovascular abdomina...

OBJECTIVE The purpose of this study was to define changes in aneurysm volume after endovascular repair of abdominal aortic aneurysm. METHODS A total of 154 consecutive patients who underwent endovascular repair of abdominal aortic aneurysm with the Medtronic AneuRx stent graft at Stanford University Hospital were evaluated. During a mean follow-up period of 15.8 +/- 11.3 months, serial comput...
