May warrant slower balloon inflation in EVAR; case reports leave open incidence and optimal technique.
Since the report of the first endovascular repair of an abdominal aortic aneurysm (AAA) by Parodi et al. in 1991, endovascular aneurysm repair (EVAR) has been accepted as an alternative to traditional open surgery in selected patients (13). Despite the minimally invasiveness of this treatment, there are several complications that may occur during or after EVAR. Complications include endoleak, graft thrombosis, graft kinking and migration, aortic dissection, distal embolism, or iatrogenic injury to the access artery (rupture, dissection, and false aneurysm) (1-8). However, there are few reports on the vascular rupture caused by a molding balloon during EVAR (8, 9). We report two cases of infrarenal AAA complicated by procedure-related aortic or iliac artery rupture by the molding balloon during EVAR.

Lee et al. (2011) conducted a case report in Infrarenal abdominal aortic aneurysm (n=2). Endovascular aneurysm repair (EVAR) with molding balloon dilatation was evaluated on Vascular rupture (aortic or iliac artery). Rapid inflation of a molding balloon during endovascular aneurysm repair caused a sudden abrupt increase in endograft diameter, leading to aortic or iliac artery rupture in two patients.
