Branched graft technique for middle aortic syndrome - Three case reports

Background. Middle aortic syndrome is a rare disease caused by stenosis of the distal thoracic and abdominal aorta involving the visceral and renal ar teries. Methods. We performed reconstructive bypass surgery for three middle aortic syndrome patients. We used magnetic resonance angiography as well as conve ntional angiography to assess the stenotic vessels. According to these data , branched graft was fabricated preoperatively, We selected Dacron for aort ic bypass graft, and ePTFE for the branch graft. In previous reports, branc hed 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 preop erative angiographic findings, the reconstructive surgery is thought to pro ceed more safely.
