Primary bypass surgery from the descending aorta to the iliac arteries for a severely calcified aorta: Report of two cases

摘要

We herein report two patients with end-stage renal failure who complained of disabling claudication due to abdominal aortic atherosclerosis. Both were on chronic hemodialysis for more than 15 years, and their abdominal aorta was densely calcified. We elected to perform a descending aorta to iliac artery bypass in order to avoid hazardous clamping of the calcified aorta. Hemodialyisis was able to be resumed on the first postoperative day. They tolerated the operation well and their symptoms disappeared. This operative procedure is therefore considered to be a useful option for patients with a porcelain aorta who are on chronic hemodialysis.
