Compliance measurements of 53 long saphenous veins before femorodistal bypass have been performed using a duplex scanner with venous occlusion for distension. These have been compared with the histological features of the veins. There was significantly more moderate or severe focal hyperplasia and circular muscle hypertrophy in distal long saphenous vein than in its proximal counterpart (P < 0.01 and P < 0.05 respectively). The mean (95 per cent confidence interval) compliance of distal vein with moderate or severe hyperplasia was 0.16 (0.13-0.19) compared with 0.29 (0.22-0.36) for that with no, minimal or mild hyperplasia (P = 0.001). The mean compliance of distal vein with moderate or severe muscle hypertrophy was 0.19 (0.17-0.21) and of vein with no, minimal or mild hypertrophy 0.25 (0.21-0.29) (P = 0.14). The mean lowest compliance in seven patients who developed stenosis was 0.10 (0.07-0.13) compared with 0.21 (0.16-0.26) in the rest (P < 0.001). Preoperative measurement of vein compliance can be used to identify vein with marked pre-existing intimal hyperplasia and as a predictor of future graft stenosis.
在进行股腘动脉搭桥术前，使用带有静脉闭塞装置以实现静脉扩张的双功扫描仪对53条大隐静脉进行了顺应性测量。这些测量结果已与静脉的组织学特征进行了比较。与近端大隐静脉相比，远端大隐静脉中存在中度或重度局灶性增生和环形肌肥大的情况明显更多（分别为P < 0.01和P < 0.05）。有中度或重度增生的远端静脉的平均（95%置信区间）顺应性为0.16（0.13 - 0.19），而无、轻度或轻度增生的静脉的顺应性为0.29（0.22 - 0.36）（P = 0.001）。有中度或重度肌肉肥大的远端静脉的平均顺应性为0.19（0.17 - 0.21），无、轻度或轻度肥大的静脉的顺应性为0.25（0.21 - 0.29）（P = 0.14）。7例发生狭窄的患者的平均最低顺应性为0.10（0.07 - 0.13），其余患者为0.21（0.16 - 0.26）（P < 0.001）。术前测量静脉顺应性可用于识别已有明显内膜增生的静脉，并作为预测未来移植物狭窄的指标。
