A method for assessment of arterial collateral vessels and corresponding stenoses on arteriograms of arteriosclerotic legs is presented. The method is based on the concept that compensatory collateral vessels, by-passing stenoses of the conductive arterial segments, have to cross a plane traversing the distal part of each segment (common iliac artery, external iliac/common femoral artery and superficial femoral artery). The number of collateral vessels was counted and the minimum diameter within the corresponding conductive arterial segment was measured (three locations in each leg). There was a close correlation between the sum of remaining lumen diameters and the sum of corresponding collaterals in thirty-four legs (r = -0.77, P less than 0.001). Maximum lower leg blood flow during exercise (thermodilution) was better correlated to arteriosclerotic changes in the pelvic arterial tree than to changes in the femoral arteries, and the must abundant collateral vessels were found in individuals having central stenoses or occlusions.
本文介绍了一种在动脉硬化腿部动脉造影上评估动脉侧支血管及相应狭窄的方法。该方法基于这样的概念，即绕过传导性动脉段狭窄的代偿性侧支血管必须穿过横贯每个动脉段（髂总动脉、髂外/股总动脉和股浅动脉）远端的平面。计算侧支血管数量，并测量相应传导性动脉段内的最小直径（每条腿三个部位）。在34条腿中，剩余管腔直径总和与相应侧支血管总和之间存在密切相关性（r = -0.77，P < 0.001）。运动期间小腿最大血流量（热稀释法）与盆腔动脉树的动脉硬化改变相关性比与股动脉改变的相关性更好，并且在有中心狭窄或闭塞的个体中发现侧支血管最丰富。
