[Peripheral prosthesis bypass for saving the extremity].

We report the results of more than 1000 PTFE tibial bypass implantations during the last 20 years. An extra-anatomic lateral bypass to the peroneal or tibial artery prevents angulation problems. Using the Linton patch technique, early results improved to 85%. In the context of redo-operations long-term results are enhanced through the consistent use of PIDDA catheter. In 57% we achieved our purpose: limb salvage until the death of the patient or for 3-7 years (3.8 years in the middle) at the time of reexamination. Two examples of lateral tibial bypasses are given that have been functioning for 18 years.

[Leiomyosarcoma in the area of the pelvic vein].

A 37-year-old patient presented with relapsing edema of the left leg lasting for 3 months. The radiological investigations indicated a thrombotic occlusion of the pelvic veins. Surgery revealed a neoplastic growth within the common femoral vein. Histology corresponded to a leiomyosarcoma of the venous wall with intraluminal growth and no indication for penetration of the wall and invasion of the surrounding tissue. In a second operation the tumor-bearing parts of the profound and superficial femoral vein and the external iliac vein were removed. A postoperative infection with involvement of the superficial femoral artery necessitated resection of the artery and replacement by a bypass. Three months after the intervention the patients fares well. The swelling tendency of the left leg is minimal. A local recurrence of the tumor could not be detected so far. Chemotherapy was refused by the patient.

[Advantages of the combination of surgical and sclerosing treatment of varicose veins. A new kind of therapy for varicose veins].

In many patients with varicose veins the combination of surgery and sclerotherapy gives good results and reduces the operating time for each patient considerably. Especially in all patients with recurrent and side branch varicose veins this method seems to be advantageous. During the last ten years we treated 3328 patients with varicose veins. The combined method was used in 64% (2130 patients).

[Mucoid cystic adventitial degeneration of the popliteal artery with simultaneous arteriosclerosis].

A 56-year-old male patient presented with intermittent claudication due to cystic adventitial degeneration of the popliteal artery. In addition independent symptomatic arteriosclerotic alterations of several arteries distal and proximal of the popliteal artery were detected. The etiologic, diagnostic and differential-diagnostic aspects in general and the therapeutic implications of this uncommon case are discussed.

[Extra-anatomic crural reconstruction].

In the difficult field of crural surgery technical details are very important. However only if we succeed in demystifying the crural bypass and integrating it in to general surgery, will we succeed in drastically lowering the number of amputations. To achieve this aim PTFE graft was used as extraanatomic bypass. Based on experience with more than 500 operations (since 1. January 1980), the Linton patch, and not the AV-fistula, is the best additional measure for treating distal anastomosis.

[Popliteo-femoral venous reconstruction: indications and results].

In cases of a serious post-thrombotic syndrome in which conservative treatment has failed, the possibility of a venous femoralis bypass should be considered. Prerequisites for this procedure are an adaequate v. saphena magna and an open or recanalised v. poplitea at the confluens of the vv. tib. post. et vv. fib. This method was first described by May and Husni; we have modified it by replacing the original end-to-side anastomosis with a more effective end-to-end anastomosis and have added a subfascial av-fistula. Both procedures lower the ambulatory venous pressure. This operation has been performed 23 times; the paper presents the late results from 18 patients, 5 of whom underwent the operation over 8 years ago.

[Extracranial aneurysms of the internal carotid artery proximal to the skull base. A case report].

Extracranial aneurysms of the internal carotid artery are considered to be relatively rare. The main causes are constitutional vessel weakness arteriosclerosis and trauma. Neurological complications can sometimes give rise to confusing symptoms. Most important are transitory ischaemic attacks. Apart from these, damage by compression of the lower cranial and sympathetic nerves may occur. A case is reported in which the symptoms led to the topological diagnosis. The method of treatment used was that of delayed carotis ligature as described by van Dongen.

[Reconstructive surgery of the peripheral arteries in elderly people].

The results of reconstructive surgery of atherosclerotic occlusive disease in the senium are reported on 71 patients. Mortality rate of 14.68% and improvement of 63.38% showed clearly better results than described in literature with an amputation mortality rate between 26% and 60%. In the authors' opinion also in the senium the reconstructive surgery of the peripheral arterial system should be preferred if general and local operability are given.

[Pulmonary contusion after blunt chest trauma--an experimental model (author's transl)].

A model in the rat for pulmonary contusion after blunt chest trauma is described. It is possible to avoid trauma of the mediastinal organs, liver and spleen; therefore it is possible to produce pulmonary contusion with a good reproducebility. The parameter for the extent of contusion was the lungweight which rose statistically with a specific force of trauma. Simultaneous injection of high doses of prednisolone with the blunt chest trauma inhibits the increase of the lung weight.

[Aortic arch syndrome (author's transl)].

This report demonstrates a case of a fully developed aortic arch syndrome with an unusual lack of symptoms. A sufficient collateralisation and nearly free cerebral vessels were hiding the clinical manifestations of arteriosclerosis for a long time. Besides the diagnostic maneuvers the operative therapy is shown during which a short, acute circulatory failure occurred caused by a reflex reaction of the carotic sinus due to the improved blood supply.

[Different ultrastructure of the right and left myocardium after preservation for 24 hours (author's transl)].

After a 24 hrs' preservation of rat hearts, in 22% the viability test with allogenic perfusion showed a singular recovery of the right ventricle (57 of 257 experiments). The ultrastructural aspects correlate with the differences of the function. The micrographs of the right myocardium show--except a mild edema--ultrastructural integrity, but the micrographs of the left myocardium show marked alterations of the ultrastructure: edema, swollen mitochondria with destroyed cristal membranes, swelling of the sacrotubular system and alterations of myofibrils.

[Clinical experiences with autologous blood transfusion in vascular surgery].

In a prospective study 30 patients with high operative risk in vascular surgery underwent preoperative phlebotomy. Blood loss during operation could be replaced by bank autologous blood. The clinical data during and after operation are compared with the data of a control group. The use of banked autologous blood does not even endanger patients with poor cardiorespiratory function. As a clinical procedure it is easily performed and reduces the cost of medical care. The method of preoperative phlebotomy reduces the need of homologous blood by 75%. The number of patients receiving homologous blood is reduced by 50%. Banked autologous blood is an important help for the anesthetist. The basic physiologic principles of the method are discussed as well as advantage and disadvantage of preoperative hemodilution. The authors suggest to withdrawal of 800 ml autologous blood before every operation in which the blood loss will be higher than 500 ml.
