[Early and late results following 244 reconstructions of the internal carotid artery with contralateral internal carotid occlusion].

Between December 1974 and March 1985 244 reconstructions of the internal carotid artery with contralateral occlusion were performed. 7.3% of the patients were asymptomatic, 48.4% had typical transient ischemic attacks and 44.3% had a completed stroke. The postoperative mortality was 2.0% and a permanent neurologic deficit occurred in 3.3%. An intraluminal shunt was used in only 5.4%. The long-term survival rate after 5 years was 65.2 +/- 4.8%. In the follow-up period of 103 months 9.2% of the patients had a new stroke.

[Vascular surgery emergencies in geriatrics. Diagnosis and operative measures].

Particularly in the elderly patient, acute vascular occlusion must be treated quickly and with as little risk as possible. Among the surgical possibilities, preference is given to the inflatable balloon catheter to eliminate the occlusion. This procedure is usually possible in acute arterial and venous obstructions. Acute arterial thrombosis requires a vascular reconstructive procedure. Here, in unilateral thrombotic occlusion of a pelvic artery, the femoro-femoral bypass is particularly useful. After successful surgery, anticoagulant treatment should always be given unless contraindicated.

[Hemodynamic effect of carotid stenoses and longtime course following carotid surgery].

Between 1962 and 1980, a total of 706 patients with chronic arteriosclerotic vascular changes or kinking or coiling of the carotid artery, were subjected to surgery at the Surgical Department of the University Hospital at Erlangen. In 1981, a total of 703 patients were analysed to obtain information about the postoperative course. In addition to a computation of the survival rates, together with the stroke rates, broken down by the clinical stage, the preoperative haemodynamic effect of the carotid stenosis was taken into account. Patients with transient ischaemic attacks or mild cerebral infarction affecting the carotid artery territory, revealed a favourable long-term survival rate, and a low rate of strokes, irrespective of whether haemodynamically effective carotid stenoses presented or not. Patients with asymptomatic carotid artery stenosis, with chronic cerebral ischaemia, with non-hemispheric attacks, and with completed cerebral infarction, revealed, all in all, no favourable survival rates. For patients with preoperative haemodynamically effective carotid stenoses, the incidence of strokes was markedly lower than in patients without haemodynamically effective stenoses. This means that an indication for carotid artery surgery in these patients, can only be justified if the carotid stenosis is haemodynamically effective, but not if the stenosis is lowgrade.

[Potency disorders before and after pelvic artery reconstruction: objectification by measuring penile artery pressure].

Penile artery pressure was measured in 38 patients before and after aorto-iliac reconstruction using the Doppler technique. In 14 patients a markedly reduced penile pressure was found preoperatively which was significantly enhanced in 71% after operation. In 16% of all cases postoperative penile pressure was lower than the preoperative value. An improvement of sexual impairment was observed in 37% of the patients, while 26% reported a decrease of sexual function after operation. The reason seems to be an operative damage to the preaortal nerve plexus in most cases. Therefore, in younger patients with unilateral iliac artery occlusive disease an extraanatomical reconstruction is recommended.

[Transitory ischemic attacks. Results of surgical therapy].

Classical transient-ischemic attacks in patients with proven occlusive disease of the carotid arteries are an absolute indication to operate. Operative reconstruction leads to a significant reduction in the incidence of cerebral infarction when compared to conservative treatment with inhibitors of thrombocyte aggregation. The survival rate of carotid endarterectomy in this stage was 96% after 5 years and 60% after 7 years. The actual stroke rate during this observation period was 5.1%. Contralateral stenosis should be treated operatively in order to achieve further reduction in the rate of cerebral infarction.

[Late results in supraaortic reconstructions (author's transl)].

Since 1965 we have performed 602 reconstructions at the supraaortic branches, mainly at the carotid artery. Follow-up showed equally good long-term results in subclavian reconstructions by transthoracic and extrathoracic approach. The patency was 90% after 6 years. Mortality in carotid endarterectomy was 1.6%. According to the Life Table Method the survival rate was 57.6% after 5 years in stage I, 73.7% in stage II, and 66% in stage IV.

[Late results of 336 femorotibial bypasses (author's transl)].

A total of 336 femorotibial reconstructions were performed at the surgical clinic of the University of Erlangen and the Fürth City Hospital between 1966 and 1978. Mortality was 1.5%, and 89.6% of the patients were discharged with functioning reconstructions. The Life Table Method showed a patency of 58.7% after 5 years and 56.7% after 7 years follow-up for the saphenous vein graft.
