    Abstract:
    Between February 1989 and June 1991 the peripheral outflow resistance was measured at 45 patients during infragenual bypass surgery. In order to find out whether there is a correlation between successful bypass grafting and measured outflow resistance, all patients were controlled regularly. There was a significant difference in mean resistance between those grafts remaining patent and those that failed. 8 out of 11 bypasses, that failed up to one month after operation, had measured peripheral resistance higher than 1.1 mmHg x min/ml. 12 out of 15 bypass grafts remained patent for more than one month and had an outflow resistance less than 0.55 mmHg x min/ml. There is no definite correlation between a measured outflow resistance from 0.55 to 1.1 mmHg x min/ml because of the low number of patients in this group. The purpose of resistance measurement during peripheral vascular surgery was to determine a final value for a decision, if additional surgical or non surgical treatment for a better runoff is necessary. In our study this value is 1.1 mmHg x min/ml. Additional treatments are the peripheral AV-fistula and a jump- or sequential-graft. Another possibility is the intra- and postoperative application of Prostaglandin, which is in an experimental study in our clinic.
