Accurate evaluation is important. Preoperative intra-arterial digital subtraction angiography and Doppler evaluation with pulse-generated augmentation of 90 patients who underwent femorodistal reconstruction were compared with postoperative angiography. Underestimation of distal run-off of the calf vessels occurred in 33% of cases by preoperative intra-arterial digital subtraction angiography. A below-knee pulse-generated run-off score of 3 or less was associated with a 12-month cumulative patency of 73% compared with 85% with a below-knee pulse-generated run-off score of 4 or more ( P= 0.079, log rank test; P= 0.060, Wilcoxon signed rank test). The 12-month cumulative patency for grafts with a complete, incomplete and occluded arch as defined by pulse-generated run-off was 78.90 and 38% respectively (P&lt; 0.0001 log rank and Wilcoxon signed rank tests). Preoperative evaluation of distal run-off before femorodistal bypass should not be based exclusively on intra-arterial digital subtraction angiography. <\/jats:p>","DOI":"10.1177\/096721099600400208","type":"journal-article","created":{"date-parts":[[2024,9,24]],"date-time":"2024-09-24T01:41:23Z","timestamp":1727142083000},"page":"161-164","source":"Crossref","is-referenced-by-count":3,"title":["Evaluation of Distal Run-off before Femorodistal Bypass"],"prefix":"10.1177","volume":"4","author":[{"given":"A.
