[Clinical significance of peripheral vascular resistance for early bypass occlusion rate. Errors and dangers in measuring vascular resistance].
An estimation of the peripheral resistance was performed during 264 peripheral bypasses. After completion of the distal anastomosis, saline was infused via the proximal graft end in constant flow rates. The mean distal pressure was used for calculation of peripheral resistance. There was a close correlation between the peripheral resistance (based on flow rates of 100 ml/min) and the 30 day graft failure rates. Below the level of 450 mPRU the failure rate was 4%, above 750 mPRU, however, this rate was more than 20%. It is concluded, that the estimation of the peripheral vascular resistance during the operation is a valuable tool to estimate the prognosis of graft patency.
