  • Title: Suprarenal fixation resulting in intestinal malperfusion after endovascular aortic aneurysm repair.
    Author: Siani A, Accrocca F, De Vivo G, Marcucci G.
    Journal: Interact Cardiovasc Thorac Surg; 2016 May; 22(5):685-7. PubMed ID: 26826712.
    Abstract:
    Superior mesenteric artery (SMA) and coeliac axis (CA) occlusion after endovascular abdominal aneurysm aortic repair (EVAR-AAA), using endograft with suprarenal fixation, are uncommon. However, we are reporting a case of visceral malperfusion, which occurred 7 days after successful EVAR with suprarenal fixation for symptomatic AAA. Endograft metal stent barbs caused severe stenosis of SMA and CA. A successful recovery of SMA was carried out by means of a balloon-expandable stent released through bare metal stent barbs. We believe that an unfavourable anatomy of a proximal aortic neck and visceral aorta may have caused a wrong stent strut deployment with the coverage of CA and SMA.
