The judgment of the efficiency of the collateral circulation is of decisive importance for the estimation of the clinical degree of severity and thus also for the indication to angiosurgical measures. Since also angiographically only an indirect evidence concerning the collateral circulation can be given, the angiological findings of 18 patients with unilateral or bilateral occlusion of the superficial femoral artery (n = 25 lower extremities) were evaluated. On the basis of the measuring values received with the help of the phebembraxis plethysmography 3 degrees of severity may be differed which essentially correspond to clinical stage: 1. good collateral circulation (data in ml/100 ml tissue min: ff above 5 ml, pf above 15 ml, pf-time below 30 s 2. moderate collateral circulation: ff below 5 ml, pf below 15 ml, pf-time 30-60 s 3. bad collateral circulation: ff below 5 ml, pf below 10 ml, pf-time above 60 s. Of the measuring sizes (ff, pf, pf-time) the pf-time proved to be the most reliable parameter. On the basis of these results the phlebembraxis plethysmography is a valuble supplementation in the preoperative vascular diagnostics.
侧支循环效率的判断对于评估临床严重程度至关重要，因此对于血管外科手术措施的指征也很重要。由于血管造影也只能提供关于侧支循环的间接证据，因此对18例单侧或双侧股浅动脉闭塞患者（n = 25条下肢）的血管学检查结果进行了评估。根据通过肢体阻断体积描记法获得的测量值，可以区分出3种严重程度，它们基本上与临床分期相对应：1. 良好的侧支循环（数据单位为ml/100 ml组织分钟：ff高于5 ml，pf高于15 ml，pf时间低于30秒）；2. 中等侧支循环：ff低于5 ml，pf低于15 ml，pf时间为30 - 60秒；3. 不良侧支循环：ff低于5 ml，pf低于10 ml，pf时间高于60秒。在测量指标（ff、pf、pf时间）中，pf时间被证明是最可靠的参数。基于这些结果，肢体阻断体积描记法在术前血管诊断中是一种有价值的补充方法。
