Endografting in the aortic arch - does the proximal landing zone influence outcome?
OBJECTIVES To analyse early and midterm results of thoracic aortic endografting (TEVAR) in the aortic arch. METHODS Between January 1997 and February 2009 178 patients received TEVAR in the aortic arch at our institution. This population was subdivided into four groups according to the proximal landing zone (LZ) classification in the aortic arch by Ishimaru et al. and a retrospective analysis...
متن کاملDirectional tip control technique for optimal stent graft alignment in angulated proximal aortic landing zones
Angulated anatomy in the aorta, such as tortuous infrarenal aortic necks or steep aortic arches, is a significant challenge for endovascular aortic repair because it often causes inadequate sealing and fixation, which may lead to treatment failure. We have developed a technique using off-the-shelf equipment to precisely control the deployment of stent grafts in challenging landing zones. The ke...
متن کاملProximal aortic stent migration
A 21-year-old man underwent stent implantation (8Z45CP stent on 18 mm BiB-balloon, Numed, Hopkinton, NY) for a recurrent aortic obstruction, after previous repair of an aortic interruption type A. At the age of two weeks after birth an end-to-side anastomosis of the descending aorta onto the distal arch (left subclavian artery) was performed. Diagnosis of restenosis was based upon upper limb hy...
متن کاملProximal aortic arch cannulation for proximal ascending aortic aneurysms
INTRODUCTION Different arterial inflow sites have been reported to date for particularly challenging cardiac operations. The ascending aorta, femoral artery, and subclavian artery are the most commonly used sites. Although its use has been reported, the aortic arch has not gained popularity in the performance of cannulation. According to a search performed in the PubMed database, aortic arch ca...
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...
