We performed 6 revascularization procedures in 5 patients after removing aneurysms of the superficialized brachial artery. The patients were 2 men and 3 women with an age range of 52 to 73 years. Their periods of hemodialysis ranged from 1 to 10 years. The aneurysms included 3 unruptured aneurysms, 1 ruptured aneurysm at the anastomosis site of an arteriovenous fistula and 1 ruptured infected aneurysm. Three procedures with interposed techniques for aneurysms and 3 brachial-urnal bypasses through the ulnar side roots of the elbow were performed with saphenous vein grafts (SVG) for revascularization. Two interposed SVGs closed after operation angiographically. In contrast, all brachial-ulnar bypass SVGs remained patent. One patient of the 2 graft occlusion patients had a ruptured infected aneurysm, and the other patient had exercised his elbow joint actively after operation. In conclusion, brachial-ulnar bypass through the ulnar side roots in the elbow is an effective revascularization technique for patients who exercise the elbow joint after operation or who have infected aneurysms.
