title: The correlation of peroperative outflow resistance measurements with patency 109 infrainguinal arterial reconstructions.
abstract: The predictive value of outflow resistance measurements for the patency of femoro-popliteal and femoro-crural bypass grafts was analysed. Peroperative outflow resistance measurements were performed in 109 infrainguinal arterial reconstructions. Outflow resistance was significantly higher in occluded bypasses compared with those which remained open (P less than 0.01), but there was a considerable overlap of values in both groups. Statistical analysis of the correlation between outflow resistance and patency rates at 3 months revealed a marginal correlation in the femoro-popliteal bypass group (R = -0.25), which was not significant (P = 0.064). In the femorocrural bypass group there was again only a marginal correlation (R = -0.27) but this was statistically significant (P = 0.05). These data demonstrate that intraoperative outflow resistance measurements are only of limited value for predicting bypass patency in individual cases.
