Endothelium-dependent acetylcholine-induced vasodilatory response of saphenous vein grafts.
INTRODUCTION It has been suggested that endothelial dysfunction is critical to saphenous vein graft (SVG) occlusion. AIM To evaluate in vivo endothelium-mediated vasoreactivity in angiographically non-stenotic SVG. METHODS The group consisted of 31 patients (pts), aged 58.7+/-8.7 years, 54+/-38 months after coronary bypass surgery. In each patient one angiographically normal SVG was selecte...

متن کاملEndothelium-dependent relaxation of human basilar arteries.
We studied the effects of acetylcholine and calcium ionophore A23187 on human basilar artery rings. Among 11 arteries, both agents produced significant relaxations in five, A23187 but not acetylcholine caused a response in six, and neither agent was effective in four. After rubbing off the endothelium, the relaxations induced by both agents were significantly attenuated. Indomethacin (a cycloox...
متن کاملPathologic changes in aortic-coronary arterial saphenous vein grafts.
This is a pathologic study of segments of saphenous vein used as a graft between the aorta and a coronary artery in the surgical treatment of coronary atherosclerosis. Except for an occasional case with thrombotic occlusion of the graft, no lesions were observed in grafts which had been in place for less than 1 month. In each of two grafts in place for 1 month, mild fibrous thickening of the in...
