Prostacyclin aerosol (100 ng/kg·min) caused selective pulmonary vasodilation without causing systemic hypotension in an infant with idiopathic pulmonary hypertension. Cardiac index increased suggesting improved right ventricular function. Aerosolized prostacyclin causes selective pulmonary vasodilation and may thereby improve systemic haemodynamics in(More)
The authors report an interesting case of arterio-venous fistula in the uterine vessels in a young two-para of 23 years of age. A pulsatile and throbbing mass was found in the right parametrium at her post-natal visit after the second delivery, although no abnormal sign had been noted during the pregnancy. The diagnosis was confirmed by arteriography. Two(More)
A new technique for treating obliterations of the proximal subclavian artery is described. It consists of anastomosing the cervical part of the artery with the common carotid artery. The authors have used this technique in 4 patients. The operation and post-operative course were uneventful. The functional disorders regressed and velocimetric tracings(More)
A series of 215 patients who had undergone 250 carotid artery operations were followed up for a mean of 30 months. Perioperative mortality was 2%, neurologic morbidity was 7% but with permanent sequelae in 1.39% of cases. Recurrence of stenosis was detected in 0.8% of patients but there were no cases of postoperative thrombosis. Indications for surgery were(More)
26 subjects underwent surgery for impotence of arterial origin between January, 1976 and January, 1979. The mean age of these patients was 49.6 years. The post-operative course was followed up with a mean period of 19.6 months. The 3 epigastrico-cavernous bypasses gave no good results beyond the third month. The best results were seen in lesions situated(More)
100 patients with stage II arteritis (claudication alone) were operated on. In the vast majority of cases (78%), the lesions were aorto-iliac. The operative mortality was nil. The immediate follow up period included 2 thromboses requiring 2 reoperations. The long term follow up, on average 22 months (from 8 months to 3 years) was very satisfactory with a(More)
With the aim of diagnosing possible arterial causes of sexual impotence, a Doppler study of the arteries of erection (dorsal arteries of the penis, left and right cavernous arteries) was performed according to an original protocol on 132 patients with cardiovascular disease. The Doppler study included recording of mean arterial flow and the measurement of(More)
