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.
我们对155例接受血管重建术后患有慢性动脉闭塞性疾病的肢体进行了血流测量。在标准电磁流量计技术操作过程中记录血流情况。记录了使用罂粟碱进行最大程度血管扩张后的基线血流。确定即时效果的最重要测量指标是动脉内注射30毫克罂粟碱后基础血流的增加百分比。在主-髂血管重建术中，我们发现根据流出道不同，即股浅动脉是通畅还是闭塞，存在显著差异。近端吻合口位于主动脉或腋动脉的移植物产生的血流比来自对侧股动脉的移植物更好。口径不足的静脉移植物可能会导致压力梯度高于10毫米汞柱。在这些情况下，血流会更低。血流测量有助于在动脉病变意义存疑的病例中选择合适的外科手术。
