Endovascular Management of a Ruptured Thoracoabdominal Aneurysm-Damage Control With Superior Mesenteric Artery Snorkel and Thoracic Stent-Graft Exclusion

ÌÇÐÄ´«Ã½

Abstract

We report a case of a large ruptured thoracoabdominal aortic aneurysm, which was stabilized with endovascular aortic exclusion and snorkel bypass of the superior mesenteric artery (SMA). An 80-year-old African American woman with multiple medical comorbidities and previous open infrarenal abdominal aortic aneurysm repair presented with a ruptured 10.7 × 7.3 cm thoracoabdominal aortic aneurysm involving the origins of the renal and mesenteric vessels. The patient underwent emergent endovascular aortic repair with placement of a covered stent into the SMA coursing parallel to the aortic endograft. This technique was initially successful in clinically stabilizing the patient; however; 3 weeks after the initial procedure, she presented with recurrent rupture necessitating proximal extension of her snorkeled SMA bypass and aortic endograft into the mid-descending thoracic aorta. The patient stabilized and was successfully discharged home.
