[Transjugular vena cava umbrella placement (author's transl)].

In order to prevent venous emboli originating from the veins of the lower extremities to pass through the inferior V. cava, its passage can be blocked without interrupting the blood stream. This is done by inserting an umbrella filter in the inferior V.

Management of concomitant occlusive disease of the supraaortic and lower-limb arteries.

Angiography examinations of the extracranial cerebral arteries in patients with peripheral occlusive disease of the lower limbs indicate cerebro-vascular disease more often than might be assumed from clinical-neurological examinations alone. In total, 61.5% of the patients examined showed lesions of the extracranial cerebral arteries which necessitated an operation.

[Operative treatment of deep vein thrombosis (author's transl)].

From 1973 to 1977 a total of 63 patients with thrombosis of the deep veins in leg and pelvis and in the V. cava inferior was treated by operative thrombectomy. Prior to the operation all patients were submitted to phlebography.

[Surgical treatment of therapy resistant ulcus cruris (author's transl)].

30 patients with chronic venous ulcerations of the lower leg, unable to be cured definitely by commonly known medical, local or surgical therapy are reported. All patients were submitted to the little known ulcer circumcision published by Nussbaum in 1873. During a postoperative period of up to 10 years there was no recurrence of ulcers in any case.

[New technic of the transjugular cava blocking in the removal of acute pelvic vein and inferior vena cava thrombosis].

Thrombosis of the inferior vena cava rarely occurs. However, it mostly develops by continous growth from thrombosis of the deep leg and pelvic veins. Thrombus formation in the inferior vena cava carries a potentially lethal risk because of possible involvement of the renal veins with consecutive renal failure or development of fulminant pulmonary embolism.

[Orthotopic saphena bypass in situ (author's transl)].

A procedure intended to restore the obliterated femoropopliteal arterial pathway is described. The vena saphena magna is canulated with a silicone tube, thus fixing the valves against the venous wall, the side vessels thrombose and close by secondary organization. After 6 to 8 weeks the transformed vein will be interposed instead of the obliterated arterial segment.

[Prolonged extracorporeal membrane oxygenation in the treatment of burns-induced shock lung (authors transl)].

A case of third-degree burns involving 35 per cent of the body surface is reported with occurred in a 28-year-old man. On the 6th day progressive pulmonary insufficiency developed which 3 days later necessitated extracorporeal membrane oxygenation. Oxygen diffusion capacity gradually improved and the patients resumed spontaneous respiration with oxygen enriched air.

[Angina abdominalis: Clinical findings and therapy (author's transl)].

Angiographic and clinical findings of angina abdominalis are demonstrated by the clinical course of four patients. Two of them suffered from athero-sclerotic stenosis and the remaining two from compression of the coeliac trunc respectively the upper mesenteric artery by fibrotic strings. One patient was treated by an interposition of a saphenous vein graft another one by tissue decompression.
