The long-term results of 37 carotido-subclavian grafts was 100% till the end of the third year. This method is now our preferred method for correction of subclavian lesions. The operative mortality was 0%. The long-term results of the femoro-femoro bypasses was 79.7% from the third through the fifth year. 5 out of 7 axillo-femoral grafts remained patent. In our opinion the axillo-femoral bypass should only implanted in patients with an infected area in the aortoiliac segment but not routinally.

Digital transvenous angiography in follow-up examinations after carotid reconstruction: early results.

A total of 187 check-up examinations by DVSA were carried out after various types of carotid reconstructions. The results were inconclusive in only 2.7% of the cases. A good or very good postoperative result could be demonstrated in 77.5%. A slight stenosis was present in 16%, a significant stenosis in 2.7% and a complete occlusion of the internal carotid artery in 1.1%. Patch plasty alone showed the best results followed by endarterectomy and endarterectomy with patch plasty. Segmental carotid resections and dilatations led to the poorest results. Most of those cases, where a stenosis recurred, it was already present immediately after the operation and only rarely caused by progression of the basic disease or intimal proliferation. The complication rate of DVSA was low. It is concluded that DVSA is a low risk and reliable method which can routinely be used in the postoperative evaluation of patients with carotid reconstructions.

Surgical treatment of renal artery occlusive disease: long term results.

68 patients were operated on for renal artery occlusive disease. After a mean follow-up of 61 months renovascular hypertension was cured or markedly improved in 79.2%. The results depended mostly on the duration of preexisting hypertension and on the histology of the renal artery lesion. Forty-four months after surgery, 37 reconstructions were examined by angiography. Mostly digital subtraction technique was used. Total occlusion rate was 24%. Patency rates of autogenous vein bypass grafts were similar to prosthetic grafts. It is concluded that prosthetic grafts like PTFE are a reasonable alternative in aortorenal bypass procedures.

Long-term results of femoro-popliteal/tibial bypasses with special references to re-operation in former femoro-popliteal procedures.

Since 1962 a total of 1,361 femoro-popliteal/tibial reconstructions have been performed and followed up. In addition to the saphenous vein, Dacron, PTFE, and umbilical vein grafts were used. The following long-term results were achieved: The saphenous vein grafts have a patency of 73.6% after 10 years and of 52.2% after 17 years. Cumulative patency rate for the PTFE grafts were 76.4% after 39 months with above knee and 62.2% after 2 years with below knee reconstructions. After 12 months 85.7% of the umbilical vein grafts were functioning.

Late results with Dardik-biograft in peripheral arterial surgery.

A total of 117 vascular reconstructions below the inguinal ligament were performed using Dardik's human umbilical vein. The indication for surgery was limb salvage in 91.5%. In 61.5% a previous reconstruction had failed. The distal anastomosis was done with the popliteal artery above the knee in 9 cases, below the knee in 41, and with a tibial or the peroneal artery in 60 cases. The umbilical vein was combined with a prosthesis or the autologous saphenous vein in 20 cases. The cumulative patency rates of all reconstructions were 59.6% after 3, and 46.7% after 6 years. Crural reconstructions had a cumulative patency rate of 52% 3 years after surgery. The main factors influencing patency were the preoperative grade of ischemia, the site of the distal anastomosis and the angiographic run-off. It is concluded that the human umbilical vein is the graft material of choice in long length revascularization whenever the saphenous vein is not available.

Composite grafts: an alternative to saphenous vein for lower extremity arterial reconstruction.

In the absence of adequate saphenous vein for femoral-popliteal/infrapopliteal bypass grafts, composite grafts constructed with PTFE (Gore-tex) and short segments of autogenous tissue were utilized. The composite grafts (208 cases) were compared to plain PTFE (Gore-tex) grafts (235 cases) and to the literature results reported for saphenous vein grafts (2,108 cases) in limb salvage situations. Evaluation using life table analysis with followup extending to 63 months indicates composite grafts yielded favorable results when compared to the "gold standard" of saphenous vein and superior results to plain PTFE (Gore-tex) grafts for infrapopliteal bypass. A combined, dual center approach was chosen to enhance significance by expanding the number of patients evaluated and extending the period of followup from earlier studies reported separately from each center.

Our experience of surgery for innominate and subclavian lesions.

Since 1965 we have performed 67 operations to correct a subclavian steal-syndrom. Mortality after transthoracic correction in 30 patients was 6.7%, but we lost no patient after 37 extrathoracic reconstructions. The long-term results in these reconstructive procedures were excellent with a patency of 94.7% from the forth through the fifth year after transthoracic approach. Over 90% of the patients were asymptomatic or improved.

The tibio-peroneal reconstruction in reocclusions after femoro-popliteal procedures.

After a reocclusion of the femoro-popliteal segment with run-off problems, there is frequently still the possibility of a crural revascularisation. After an exact pre- or intra-operative angiography, there is a choice to reconstruct the tibio-peroneal trunk by autologous saphenous vein graft, composite graft and, if a vein is not available, with the PTFE prosthesis or umbilical vein.
