Saphenous vein harvesting, though a relatively minor part of the coronary artery bypass operation, can cause complications that may dominate the early and late postoperative course. We describe three groups of complications that are usually given little attention in the literature: complication of vein harvesting in ischemic legs, recurrent cellulitis in vein donor legs, and saphenous neuropathy.
One hundred and fifty nine patients underwent surgery for abdominal aortic aneurysm (AAA) from 1975 to 1985. Of these, a tube graft was inserted in 86 patients (55.1%). Immediate and late results of these 86 patients were evaluated retrospectively as to the effect of concomitant common iliac artery (CIA) disease on early and late results. There were 77 males and nine females aged 35-91 (average 70.7) years. Surgery was elective in 44 patients (51.2%), and as an emergency due to expanding, ruptured or thrombosed AAA in 42 patients (48.8%). The CIAs showed unilateral or bilateral aneurysmal dilatation or atherosclerotic changes in 47 patients (54.7%). At the time of surgery additional bypass grafting from the tube graft to one femoral artery was performed in four patients, and patch angioplasty to the CIA in one. Operative mortality was 4.6% (two patients) in the elective group, and 45.2% (19 patients) in the emergency operations. Follow-up was 94% complete for a mean of 4.1 (range 0.5-10) years). Late mortality for the whole series was 20.0% (12 patients). Only one patient died of a cause related to the AAA operation. All but one of the 48 late survivors are free of any peripheral vascular problems. We conclude that tube graft replacement of AAA is a good choice even in the presence of some degree of CIA atherosclerosis or aneurysmal dilatation.
