[Combined surgical treatment for coronary heart disease as well as heart valve diseases and carotid artery stenosis].

This is an account on combined procedures in 124 patients suffering from arteriosclerotic vessel disease. In order to judge the proceedings and the results the patients were divided up into two groups. in 15 patients (group I) a carotid endarterectomy combined with an aorto-coronary bypass operation was performed; once a subclavian artery stenosis was resected at the same time. One patient of that group died after 31 days (7%). In group II 108 heart valve operations were performed together with a coronary artery revascularisation. Early and late mortality divided up as follows: aortic stenosis 6/44 (14%) respectively 2/44 (5%); aortic insufficiency 1/14 (7%) resp. 0; combined aortic disease 1/8 )13%) resp. 0; mitral stenosis 1/11 (9%) resp. 0; mitral insufficiency 6/26 (23%) resp. 2/26 (8%); combined mitral valve disease 1/2 (50%) resp. 0; three times both valves (aorta, mitral) were replaced without mortality. In our opinion combined procedures, resection of supraaortic artery stenosis respectively cardiac valve operations and aorto-coronary bypass are indicated especially since the functional long-term results are excellent. Though one should consider the high operative risk in patients with mitral insufficiency and combined mitral valve disease.

[Vascular surgery in arterial occlusive disease. Possibilities and indications (author's transl)].

Besides amputation and resection of the sympathetic trunk, vascular reconstructive operations are among the most important surgical possibilities for the treatment of arterial occlusive disease. Disobliteration and bypass procedures come into consideration. Depending on the localization of the obstruction and the affected organ, one or the other method will be given preference. The indication for vascular reconstruction is principally governed by the disease complex, the danger to the organ due to the reduced blood supply and finally the extent of the arterial obstruction. The lethality of the intervention, the results, complications and follow-up are discussed in detail.

[Lymphographic investigations of oedema of the extremities following reconstructive vascular surgery in the femoro-popliteal territory (author's transl)].

In 37 patients, oedema of the legs was observed following successful femoro-popliteal surgery; lymphangiograms were performed between the third and ninth post-operative days and the intact lymph vessels at the knee and at the groin were counted. In 27 patients there was partial to total disruption of the lymphatic vessels. There was a clear correlation between the degree of swelling of the leg and thigh with the number of not divided lymphatic vessels at the knee and groin. In the presence of more than three intact lymph vessels, swelling amounted to only 1 to 2 cm., whereas if all lymph vessels had been divided, swelling amounted to 7 cm. Extensive soft tissue trauma and repeat surgery resulted in a greater reduction in intact lymph vessels and correspondingly more oedema than was found with more conservative surgery and after initial operations. The pre-operative condition of the arteries, the presence of venous disease and the postoperative blood-flow in the leg had no influence on postoperative oedema. In order to avoid post-operative lymphoedema, it is necessary to preserve the lymphatics during surgery. Marked oedema requires treatment consisting of compression bandages and medicaments.

[The revascularization of the profunda femoris artery (author's transl)].

The revascularization of the profunda femoris artery, the minimal vascular operation, is described in this paper. After the anatomic and pathological relations of the femoral arteries the indications and the position of the profunda-revascularization in vascular surgery of the thigh are reported. During a period of 15 years (1959-1974) a profundaplasty was performed in 357 cases on 308 patients in the Munich University Surgical Clinic. The result of the operation could be controlled in 320 cases. The lethality-rate of operation is 3,8%. The operation was successful after 5 years in 75,3%, after 10 years in 62,6% in the whole period in 60% of the living patients. If there is a vascular disease of the deep femoral artery, the profundaplasty proves to be a standard technique in the vascular surgery of the thigh.

[Change in indications for reconstruction of supraaortic extracranial arteries (author's transl)].

Analysis of 334 patients, operated upon from 1962 till 1976 because of obstructions of the extracranial cerebral vessels demonstrates a change in the indication for reconstruction during the last years. The aspect of prophylaxis of neurological damage by prompt reconstruction becomes increasingly important which is documented by an increase of patients which were operated upon a) in the asymptomatic stage, b) bilaterally, c) for internal carotid occlusion during the stage of increasing neurological symptoms after they were selected according to certain criteria.

Peripilar keratin casts: a study with the scanning electron microscope.

Two cases of Peripilar keratin casts are presented and the results of a Scanning EM investigation are discussed. The surface of the casts is very irregular and disordered. In the underlying structure of the casts the characteristic image of a "sponge" is observed. The cuticle of the hair beneath is slightly flaky, showing fissures. The hair surface facing the peripilar casts is normal.

[Atypical suprarenal aortic stenosis as a cause of hypertension in young people (author's transl)].

In nine of ten hypertensive patients with "atypical" suprarenal aortic stenosis (aged 20 to 51 years, mean 28.5 years), operative treatment of the stenosis reduced blood pressure to normal. In the tenth patient, combined vascular and reno-parenchymal hypertension was effectively treated by drugs, the dosage of which could be reduced after resection. Aorto-aortic bypass was the operative procedure of choice because of its lower risk and better results than other methods. In a review of 346 cases of atypical coarcation reported in the literature, two-thirds were found to be located above or at the level of the renal arteries, causing marked hypertension. Surgical procedures and results in 136 operated cases are tabulated and discussed.

[Preliminary experiences in use of the Sparks prosthesis for femoro-popliteal bypass and arterio-venous shunt in chronic hemodialysis (author's transl)].

The present paper summarizes our preliminary results using the Sparks-Mandril. The prothesis has been applied both as femoro-popliteal bypass graft and as arteriovenous shunt for hemodialysis in patients suffering from chronic renal failure. Indications, techniques and results of implantation both as femoro-popliteal bypass and as a.-v. shunt are outlined. It is concluded that in both cases the Sparks-Mandril has its well defined field of application.
