The results of a prospective, nonrandomized, multicenter clinical trial that compared endovascular stent graft exclusion of abdominal aortic aneurysms with open surgical repair are presented. During an 18-month period, 250 patients with infrarenal aneurysms underwent treatment at 12 study sites-190 patients underwent endovascular repair using the Medtronic AneuRx stent graft (Sunnyvale, Calif),...

BACKGROUND In total arch repair with open placement of a triple-branched stent graft for acute type A aortic dissection, the diameters of the native arch vessels and the distances between 2 neighboring arch vessels did not always match the available sizes of the triple-branched stent grafts, and insertion of the triple-branched stent graft through the distal ascending aortic incision was not ea...

BACKGROUND The primary experience of open triple-branched stent graft placement for acute aortic arch dissection was reported. METHODS Between January 2011 and October 2011, 13 well-selected patients (mea age, 46±8.2 years; approximate range, 30~58 years) with acute aortic arch dissection underwent open triple-branched stent graft placement for total arch reconstruction. The triple-branched s...

AIM To compare polytetrafluoroethylene stent graft (PTFE) with sirolimus and bare metal stents in reducing in-stent restenosis in native coronary vessels in patients with acute coronary syndrome. METHODS The study included patients who underwent stent implantation in acute coronary syndrome from January 2003 to May 2004. The patients (n=119) were randomized either to stent graft group (n=40),...

Coronary aneurysms in adults are rare clinical entities. Herein, we presented a 54-year-old man who was admitted with an acute extensive anterior myocardial infarction. The emergency coronary angiography revealed an isolated large aneurysm at the proximal segment of the left anterior descending coronary artery. The patient was successfully treated with a graft-coated stent

The mechanical behavior of aortic stent grafts plays an important role in the success of endovascular surgery for aneurysms. In this study, finite element analysis was carried out to simulate the expansion of five marketed stent graft iliac limbs and to evaluate quantitatively their mechanical performances. The deployment was modeled in a simplified manner according to the following steps: (i) ...

OBJECTIVE To evaluate the outcome of endovascular stent graft placement in patients with acute thoracic aortic syndromes. METHODS Emergency stent-graft implantations were performed in 57 patients with acute thoracic aortic syndromes from May 2001 to December 2005 (45 Stanford B aortic dissections, 9 acute penetrating aortic ulcers or pseudoaneurysms. 3 traumatic thoracic aneurysms). The clini...

Open stent grafting is an alternative treatment for extensive thoracic aortic replacement. However, this procedure is associated with a high incidence of spinal cord injury, which has limited its application. Multiple factors have been suggested to explain the risk of spinal cord injury, including deep delivery of the stent graft, history of operation of the downstream aorta, and postoperative ...

Giant-cell arteritis is associated with a higher risk of aortic aneurysm and aortic dissection formation. We present a women with aortic dissection type B treated with a stent graft and bare-metal stent implantation. After the stent deployment we noticed aortic rupture, which was successfully treated with implantation of an additional stent graft. This report highlights the difficulty of endova...

OBJECTIVE Our objective was to assess potential causative factors of stent-graft collapse after thoracic endovascular aortic repair. METHODS We retrospectively reviewed clinical data and preoperative and postoperative computed tomographic scans of patients with thoracic stent-graft collapse in 2 French departments of vascular surgery. Aortic arch angulation, length of the lack of device wall ...
