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. The elimination of risks in an operation requiring extensive peripheral vessel reconstruction necessitates initial supraaortic vessel reconstruction. Of the 48 patients with reconstructions in both vascular systems, none has suffered any postoperative neurological dysfunction. Concomitant occlusive disease of the supraaortic and peripheral arteries should not be treated simultaneously.

[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. The mean age of all was 52 years. One patient died from pulmonary embolism during thrombectomy, there was no further hospital mortality. Because of low mortality incidence and rarely postthrombotic complications we prefer the operative treatment of deep vein thrombosis. The preoperative cavography helps to avoid pulmonary embolism during thrombectomy.

[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. The operation is simple and time saving. Requiring an average hospital stay of 24 days, thus saves expenses as well. The procedure is described and the clinical results obtained have been documented.

[Surgical interventions in pacemaker patients (author's transl)].

In this paper 44 operations in patients with cardiac pacemakers have been reported. Electrosurgical instruments were used in almost all cases. It was noted, that neither a disturbance of the pacemaker nor of the heart stimulated by it occured during or after operation. A premature exhaustion of the battery was not observed.

[Radiological lung changes in progressive pulmonary insufficiency (author's transl)].

Chest radiographs can reflect increasing pulmonary insufficiency of shock lung. In the early and intermediate stages, there is almost pure interstitial oedema which, in the later stages becomes alveolar-interstitial. In addition one may find evidence of broncho-pneumonia. Respiratory insufficiency is due to abnormalities of perfusion and distribution and is aggravated by disturbance of oxygen diffusion. The latter is due to an increase in the alveolo-capillary diffusion distance in the presence of interstitial oedema. It was not possible to demonstrate quantitatively significant precapillary shunts greater than 25 mu.

[The effects of dihydroergo-corine,-cryptine and-cristine on Haemodynamics in experimental cardiogenic shock].

Experimental results demonstrate, that serial ligatures of the side brances of the anterior descending and circumflex artery in the openchest dog produce a hemodynamic and electrocardiographic criteria fullfilling cardiogrenic shock. The application of the alpha-receptor-blocking agens Hydergin is followed by a statistically significant increase of the mean aortic pressure, the left ventricular systolic pressure and the mean blood flow in the femoral artery. The left ventricular enddiastolic pressure in the left ventricular enddiastolic pressure in the left ventricle decreases statistically not significant, dp/dtmax is unchanged. Hydergin effects a slope of the increased peripheral vascular ristance; if the peripheral vascular risistance is lowered during cardiogenic shock, there will not be a further lowering after treatment. The results show, that Hydergin causes a dilation of peripheral vasoconstricted vessels without unwanted hemodynamic side effects.

[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. He died 5 days after membrane oxygenation was discontinued due to massive haemorrhages from an infection at the site of the femoral by-pass. The technique adopted for the perfusion, which lasted 83 hours, is described.

[Diagnosis and therapy of pulmonary sequestration (author's transl)].

Pulmonary sequestration is a rare malformation which is characterised by lacking connection to the bronchial system and by atypical arterial blood supply. Unidentifiable tumorous, cystic or infiltrative lung diseases, especially of the lower lobes, should always lead to aortography to exclude pulmonary sequestration.
