Endoluminal embolization and revascularization for complicated mesenteric pseudoaneurysms: a report of two cases and a literature review.

ABSTRACT

Mesenteric artery pseudoaneurysms are a rare and complex complication after abdominal trauma, surgery, or inflammatory disease. These lesions can be associated with compression or erosion into adjacent structures and may result in life-threatening hemorrhage. Traditional management has been open surgical ligation, aneurysm resection with interposition grafts, or resection or partial resection of the end organ involved. We present two cases of endovascular repair of complex mesenteric pseudoaneurysms. One patient presented with a recurrent pseudoaneurysm of the superior mesenteric artery and the second presented as recurrent gastrointestinal bleeding secondary to a traumatic celiac artery pseudoaneurysm-to-pancreatic duct fistula. A systematic review of the literature on endovascular management of mesenteric vascular disease and mesenteric pseudoaneurysms is included in this report to allow these cases to be put into proper perspective.
