Coronary stent fractures have been suggested as a potential new mechanism of restenosis. The mechanical properties of stents were designed not only to prevent vessel recoil, but also to resist the mechanical stress of vessel movement over millions of cardiac cycles. We present a case in which mechanical stress may have contributed to the fracture of a stent implanted in a saphenous vein graft (...

Subclavian artery (SCA) perforation is a rare complication while performing SCA intervention. In our present report, a 73-year-old female, with stenosis of the left SCA and situs inversus, presented with exercise-induced left arm weakness. The SCA stenosis was treated with direct stenting with a balloon-expansible Express LD 10×25 mm stent. However, it caused iatrogenic SCA perforation and hemo...

PURPOSE To describe a new technique to assist aortoiliac stent-graft implantation in the presence of severe and extensive calcification. TECHNIQUE The use of an aortic stent-graft telescoped into the aorta and deployed partly within and partly outside the aorta is illustrated in 2 cases. In the first, the bifurcated stent-graft was deployed with the proximal end and body intraluminally within...

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...

OBJECTIVE The objective was to review the current results of endovascular abdominal aortic aneurysm repair with the AneuRx stent graft and to determine the effectiveness of the device in achieving the primary objective of preventing aneurysm rupture. METHODS The outcome of all patients treated during the past 4 years in the U.S. AneuRx clinical trial was determined, and the worldwide clinical...

PURPOSE To evaluate endovascular repair of infrarenal abdominal aortic aneurysms (AAA) using the Endurant stent-graft and compare the outcomes of patients with different neck anatomies, particularly as pertains to stent-graft oversizing. METHODS A retrospective review was conducted of 75 consecutive patients (69 men; mean age 75 years) undergoing endovascular AAA repair using the Endurant Ste...

BACKGROUND Endovascular repair by stent graft has been developed as a safe and less-invasive treatment for descending thoracic and abdominal aortic diseases. In case of involvement of the aortic arch, the challenge in endovascular repair is to maintain blood flow to the brain and upper extremities. Several studies have been done trying to repair this difficult part of the aorta with different s...

Background: Endoleaks after stent-graft repair of aortic dissections are poorly understood but appear substantially different from those seen after aneurysm repair. We studied anatomical and clinical factors associated with endoleaks in patients who underwent stent-graft repair of complicated type B aortic dissections. Methods and Results: From 2000 to 2007, 37 patients underwent stent-graft re...

Although the technology of endovascular aortic repair (EVAR) for abdominal aortic aneurysm (AAA) is evolving that make it appealing for challenging anatomy, proximal aortic neck morphology, especially severe angulation, is still one of the most determinants for a successful procedure. We describe a patient of AAA with severely angulated proximal neck, in whom kinked stent graft limb occurred ag...
