Repair of a Contained Ruptured Paravisceral Aortic Aneurysm Using a Surgeon-Modified Fenestrated Endograft and Development of an Aortogastric Fistula

Abstract

Complex aortic aneurysms such as paravisceral aneurysm represent a challenging condition especially in the case of rupture. The presence of an aortoenteric fistula in this setting is associated with a very high mortality and morbidity. We report the case of a 72-year-old patient with contained ruptured paravisceral aortic aneurysm who underwent surgeon-modified fenestrated endovascular aneurysm repair (sm-fEVAR) with fenestrations for multiple renal arteries and the superior mesenteric artery. The patient successfully recovered from the repair but developed an aortogastric fistula on the basis of a preexisting gastric ulceration so that second-stage atypical gastrectomy was conducted. The further postoperative course was complicated by severe pancreatitis and sepsis resulting in multiorgan failure and in-hospital death 1.5 months later. We were able to demonstrate the technical feasibility of an sm-fEVAR for a contained ruptured paravisceral aneurysm. Coverage of the celiac artery is required in some complex cases but may lead to severe ischemic complication despite from angiographic sufficient collateralization.
