Abstract

Arterial pseudoaneurysms represent an uncommon complication of acute pancreatic inflammation or chronic pancreatitis. We describe a contained rupture of a suprarenal abdominal aortic pseudoaneurysm. An aorto-uni-iliac stent-graft was adopted as the aortic main body and was combined with two chimneys and two periscope stents for celiac/superior mesenteric artery and renal arteries, respectively. The procedure was complicated by the entrapment of the celiac sheath into the barbs of the aortic stent-graft and the attempts to remove the sheath resulted in an upward migration of the stent-grafts. A bail-out endovascular procedure was used to reline the stent-grafts and the pseudoaneurysmal sac was embolized with coils.

Keywords: aortic pseudoaneurysm; chimney technique; endovascular aortic repair; parallel graft techniques; periscope technique.
