Abstract:
Aortic aneurysms (AA) are a common complication in patients with large-vessel vasculitis, such as chronic phase Takayasu arteritis, that often require surgical management to prevent a lethal rupture. Historically, mainstay of treatment for AA in the setting of arteritis was traditional open repair. However, in this case study an alternative surgical approach was devised to successfully treat an extent III thoracoabdominal AA in a patient with a diagnosis of Takayasu arteritis and a complex surgical history that made her high risk for an open surgical intervention. This case study summarizes a hybrid surgical approach that successfully excluded a thoracoabdominal AA and revascularized the superior mesenteric artery and left renal artery, by directly accessing the infrarenal aorta and using a bifurcated abdominal aortic endograft as a two-vessel branched device.
