Endovascular Conversion Procedure for Failed Primary Endovascular Aortic Stent-Grafts

Abstract

Initial failure of successful deployment of endovascular aortic stent-grafts can be due to a variety of factors and frequently requires surgical intervention. We describe an endovascular technique for salvaging initially failed tubular aortic and bifurcated aortoiliac stent-grafts with reference to three cases.

Surgical corrections of endovascular aneurysms: Repair complications

“…Most elective re-interventions are due to endoleak. The majority of acute re-interventions are required due to stentgraft thrombosis with acute limb ischaemia 7,9,11,[14][15] . Our experience with EVAR complications requiring intervention is comparable with other presented reports.…”

“…Endovascular correction or conversion is determined to be the method of choice for most EVAR complications repair 7,9,[11][12][13][14][15] . The concept of having a "tool-box" con- .…”

“…This complications solution involving endovascular or surgical procedures, such as corrections and conversions, is reported in 10-34 % of cases 1,[6][7][8][9][10][11][12] . Well accepted by patients and technically mostly successful endovascular procedures are the methods of choice for most solutions to EVAR complications [13][14][15] . Surgical procedures are indicated in cases when endovascular repair is impossible, if it has failed or its success probability is low 16 .…”

The Perth Bifurcated Endovascular Graft for Infrarenal Aortic Aneurysms

“…All these cases occurred early in the learning curve, and displayed features that by current criteria would exclude them from an endovascular procedure. Secondary endovascular procedures performed for leaks include a Palmaz stent, two extension pieces, three endovascular conversion procedures from a bifurcate to aortouniiliac and crossover graft, 9 and embolisation of a persistently patent inferior mesenteric artery. 10…”

Stents for the Treatment of Aortic Aneurysms

“…The concept of self-expandable stent-grafts for the treatment of AAA was experimentally developed by Balko et al (3) and Mirich et al (10). Volodos et al (16) used the concept of stent-graft for the first time in humans to treat occlusive and aneurysmal aortoiliac disease.…”
