Endovascular Stent-graft Repair for Spontaneous Rupture of the Nonaneurysmal Thoracic Aorta in a Patient with Takayasu's Arteritis

Takayasu's arteritis is a disease of unknown etiology with a constellation of clinical findings primarily resulting from stenotic lesions on the aorta and its branches. Although aneurysmal degeneration is observed frequently in patients with Takayasu's arteritis, non-aneurysmal spontaneous aortic rupture is extremely rare. We report a case of endovascular stent grafting for spontaneous rupture of a non-aneurysmal thoracic aorta in Takayasu's arteritis.
