Arterial reconstructions of the lower extremities were reviewed to assess the usefulness of flow waveform analysis. Six hundred and thirty-four arterial reconstructions were divided into two groups: a former (1965-1973) group of 218 reconstructions not assessed by flow waveform analysis and a recent (1974-1985) group of 416 reconstructions analyzed according to flow waveform. The cumulative patency rates of the former and the recent group at 5 years were as follows: aorto-femoral, 75.2% and 86.7% (P less than 0.05); femoral-distal, 34.6% and 61.5% (P less than 0.001); extra-anatomical, 63.6% and 80.2% (P = 0.06), respectively. Based on the various flow waveforms evidenced intraoperatively, the cumulative patency rate of cases in the recent group with type 0 and I flow waveform was compared to the rate of those with type II flow waveform. The cumulative patency rates at 5 years were as follows: aorto-femoral, 92% and 82.7% (P = 0.15); femoral-distal, 77.7% and 49.3% (P less than 0.001); extra-anatomical, 91.8% and 68.9% (P less than 0.05), respectively. These results indicate that intraoperative flow waveform analysis is a simple and useful indicator for predicting the long-term results of arterial reconstruction.
回顾下肢动脉重建情况以评估血流波形分析的效用。634例动脉重建被分为两组：一组是过去（1965 - 1973年）的218例重建，未采用血流波形分析；另一组是近期（1974 - 1985年）的416例重建，根据血流波形进行分析。过去组和近期组5年的累积通畅率如下：主-股动脉，分别为75.2%和86.7%（P＜0.05）；股-远端动脉，分别为34.6%和61.5%（P＜0.001）；解剖外动脉，分别为63.6%和80.2%（P = 0.06）。根据术中观察到的各种血流波形，比较近期组中0型和I型血流波形病例与II型血流波形病例的累积通畅率。5年的累积通畅率如下：主-股动脉，分别为92%和82.7%（P = 0.15）；股-远端动脉，分别为77.7%和49.3%（P＜0.001）；解剖外动脉，分别为91.8%和68.9%（P＜0.05）。这些结果表明，术中血流波形分析是预测动脉重建长期效果的一种简单且有用的指标。
