A Case of Effective Balloon Fenestration for Localized Aortic Dissection Complicated with Acute Renal and Bilateral Limb Ischemia in a Thoracoabdominal Aortic Aneurysm

Abstract

An 85-year-old man visited our hospital with bilateral leg weakness. Blood tests revealed an abrupt deterioration of renal function. Computed tomography revealed a 53-mm aortic aneurysm at the level of the diaphragm with an aortic dissection after branching of the superior mesenteric artery. An emergency left axillary–left femoral artery bypass surgery was performed to secure blood flow to the kidneys and lower limbs. Five days later, a transcatheter balloon fenestration for the stenosis was performed, and the blood pressure of the infrarenal aorta was improved. Both the dorsal pedis and posterior tibial arteries became palpable, and renal function was improved.
