Subclavian stenosis/occlusion in patients with subclavian steal and previous bypass of internal mammary interventricular anterior artery: medical or surgical treatment?

There are only a few published studies on the association between subclavian steal syndrome and ischemic heart disease. The objective of this report is to evaluate the efficacy of subclavian steno-occlusion treatment in patients with subclavian steal syndrome (SSS) and previous coronary bypass. Over the last 8A years we observed 207 patients who underwent left internal mammary artery-intraventricular artery (LIMA-IVA) bypass graft.

Effects of PGE-1 in patients suffering from peripheral arterial occlusive disease.

Background: The purpose of the research is to determine the effects of PGE-1 in patients with chronic obliterans arteriopathy of the lower extremities and to investigate the possibility of its having an influence on local hemodynamics.

Methods: The study comprises 123 patients aged between 39 and 75 years, suffering from Fontaine's Stage Two peripheral arteriopathy randomised into 2 therapeutic groups: the patients of Group 1 were treated with PGE-1, those of Group 2 with the association pentoxyfillin-buflomedil by venous infusion. The following were evaluated: the free walking distance on a treadmill; Rest Flow, Peak Flow and basal and minimum vascular resistance by means of strain gauge plethysmography; RF, PF, tPF and tRF by means of laserdoppler.
