A 46-year-old female patient was admitted to the emergency room with the sudden onset of abdominal pain, back pain, and paresthesia in the right leg. An emergent chest computed tomography (CT) showed an acute Type B aortic dissection. An emergency thoracic endovascular aneurysm repair (TEVAR) procedure was subsequently performed, for an evolving visceral malperfusion syndrome. We performed the procedure using an axillary approach because the small diameter of the true lumen precluded transfemoral endovascular access. This case illustrates that TEVAR permits the treatment of complicated acute Type B aortic dissection; specifically, technical variations can expand the applicability of endovascular procedures.
