Single-stage hybrid procedure for ruptured calcified thoracic aortic aneurysm caused by Takayasu's arteritis.

A 68-year-old woman was referred to our hospital because of ruptured severely calcified thoracic aortic aneurysm on chest computed tomography. She was diagnosed with Takayasu's arteritis ~ 30 years ago and was treated with oral steroids daily. We performed total arch repair using uncalcified ascending aorta with open stent-grafting technique, and additional thoracic endovascular aortic repair immediately after open surgery to avoid type Ib endoleak. Continuous hemodiafiltration was needed owing to postoperative transient acute renal failure, following which the patient recovered. She was referred to another hospital 50 days after surgery. A single-stage hybrid procedure for ruptured severe calcified thoracic aortic aneurysm caused by Takayasu's arteritis was required in this case.
