Intraoperative blood measurements following revascularization of the lower extremities with chronic arterial occlusive disease.
We have measured blood flows in 155 limbs with chronic arterial occlusive disease after revascularization procedures. Blood flows were recorded during standard electromagnetic flowmeter techniques. Base line flows after maximal vasodilatation with papaverine were recorded. The most important measurement to determine immediate results was the percentage increase of the basal flow after intraarterial injection of 30 mg papaverine. In aorto-iliac revascularization we found a significant difference according to the outflow tract, whether the superficial femoral was patent or occluded. Grafts in which proximal anastomosis were at the aorta on the axillary artery yielded better flows than those from the opposite femoral artery. A vein graft of inadequate caliber may determine a pressure gradient higher than 10 mm. Hg. In these circumstances the the blood flow is lower. Blood flow measurements may aid in the selection of the adequate surgical procedure in cases of arterial lesions of doubtful significance.
