Collapsed bifurcated modular infrarenal endograft

Collapsed endograft and lower limb ischemia from type B dissection repaired with thoracic endovascular aortic graft and iliac stenting: A case report and review of the literature

“…Other etiologies beyond TBAD for stent graft collapse have included angulation of the aortic neck, oversized endografts, stent migration, and type A dissection. 4 Similar cases of collapsed abdominal EVAR stent grafts from TBAD have been sparsely reported in the literature. Of the 12 reported cases we found, 11 patients (92%) were male and the mean patient age was 70.8 years.…”

“…The abdominal endograft may have prevented a reentry tear, leading to a mean false lumen pressure that was much greater than the true lumen pressure. 4 , 8 Furthermore, the remodeling of an undetected aortic dissection may be a precursor for infrarenal AAA and the two events may not always be mutually exclusive. 16 Although the stent graft material might play a role in susceptibility of collapse, the number of reported cases is too small to draw definitive conclusions.…”

Stent graft collapse caused by acute aortic dissection after endovascular repair for thoracoabdominal aortic aneurysm repair

“…Stent graft collapse owing to aortic dissection after endovascular aortic aneurysm repair is extremely rare. 1 Although a treatment strategy for this type of situation has not been established, successful reexpansion of stent grafts by thoracic endovascular aortic repair 2 or axillobifemoral bypass 3 for Stanford type B aortic dissection and total arch replacement for Stanford type A aortic dissection 4 have been reported. However, our case might required not only open aortic arch repair, but also complicated endovascular repair including stent graft fixation.…”
