Background:
Middle aortic syndrome is a rare disease caused by stenosis of the distal thoracic and abdominal aorta involving the visceral and renal arteries.
Methods:
We performed reconstructive bypass surgery for three middle aortic syndrome patients. We used magnetic resonance angiography as well as conventional angiography to assess the stenotic vessels. According to these data, branched graft was fabricated preoperatively. We selected Dacron for aortic bypass graft, and ePTFE for the branch graft. In previous reports, branched graft was not applied for the surgery for middle aortic syndrome.
Results:
Using this branched graft, the clamping time and ischemic time of the organs were shortened.
Conclusions:
Using branched graft prefabricated according to accurate preoperative angiographic findings, the reconstructive surgery is thought to proceed more safely.
