Thrombotic Occlusion of Stent Graft Limbs due to Severe Angulation of Aortic Neck in Endovascular Repair of Abdominal Aortic Aneurysm
Endovascular aneurysm repair (EVAR) is a safe alternative to open surgical repair for an abdominal aortic aneurysm. However, unfavorable aortic anatomy of the aneurysm has restricted the widespread use of EVAR. Anatomic limitation is most often related to characteristics of the proximal neck anatomy. In this report, we described a patient with a severely angulated proximal neck who underwent EV...
متن کاملExplantation of aortic infrarenal stent graft
end of the stent graft is extracted from the aorta. If another graft is used, proximal anastomosis is carried out with the balloon inflated. To complete the anastomosis a second Foley catheter is passed through a limb of the new graft (Fig 2). While the original catheter is deflated and removed, the second balloon is inflated in the suprarenal aorta (Fig 3) and the anastomosis completed. ACKNOW...
متن کاملThe Relationship between Temporal Changes in Proximal Neck Angulation and Stent-Graft Migration after Endovascular Abdominal Aortic Aneurysm Repair.
BACKGROUND In recent years, endovascular abdominal aortic aneurysm repair (EVAR) for treating abdominal aortic aneurysms (AAA) has become quite prevalent in Japan. Though little information is available about temporal changes in proximal neck angulation due to the difficulties encountered in measuring the angle. Therefore, we examined temporal changes in proximal neck angulation and its relatio...
متن کاملEccentric stent graft compression: an indicator of insecure proximal fixation of aortic stent graft.
PURPOSE The purpose of this study was to determine whether radiographically demonstrated proximal stent graft contour can be used as a marker for security of proximal neck fixation after endovascular aneurysm repair. METHODS Stent graft structure was examined in 100 consecutive patients with abdominal aortic aneurysms who were treated with the stent graft. Stent graft integrity, stent contour...
متن کاملBranched endovascular stent-graft for suprarenal aortic aneurysm: the future of aortic stent-grafting?
The use of a branched endovascular stent-graft to repair an aneurysm of the visceral aorta is described. The evolving role of branched endovascular stent-grafts in the management of aortic aneurysms is discussed, and the literature reviewed.
