Effects of pentoxifylline on central hemodynamics in patients with congestive heart failure.

Pentoxifylline, a xanthine derivative with vasoactive and hemorheologic properties, was studied in regard to effect on central hemodynamics in ten patients with congestive heart failure due to aortic or mitral valve disease, mainly in NYHA group III or IV. The drug was infused intravenously in a dose of 4 mg/kg b.w.

Negative effects of dihydroergotamine (Orstanorm) on central haemodynamics and aorto-coronary bypass blood flow. An intraoperative study.

Dihydroergotamine (DHE), Orstanorm, because of its strong constrictor action on capacitance vessels, is used in the treatment of hypotension caused by orthostatism or spinal or epidural anaesthesia. Lately Orstanorm has also been used in combination with heparin as prophylaxis against postoperative thromboembolism. In the present study, Orstanorm (0.

The advantage of the thoraco-retroperitoneal approach for aortorenal bypass grafting.

Postoperative angiographic studies after aortorenal saphenous vein bypass grafting have revealed a high incidence of graft dilatation and aneurysms. The aortorenal bypasses in all these series were performed via the transabdominal approach which gives an angle of at least 90 degrees between the graft and aorta. The routine approach in the present study has been the thoraco-retroperitoneal one which has been used since more than 20 years in 189 patients.

Central, high flow subclavian artery-internal jugular vein fistula for venous access.

A subclavian artery--internal jugular vein shunt was created for intermittent parenteral infusions in six patients who had undergone extensive intestinal resection because of Crohn's disease or ulcerative colitis. The flow rates through the shunt were initially around 1000 ml/min. In three patients the flow later increased, giving rise to mild cardiac symptoms.

Surgical management of obliterative disease of the brachiocephalic trunk. Experience from 24 cases.

Transsternal endarterectomy was performed in 24 patients for symptomatic obliterative disease of the brachiocephalic trunk in the period 1961-1981. In 10 of the patients the vessel was occluded, and in 14 there were various degrees of stenosis. Reversal of vertebral artery flow was found in 15 patients.
