BACKGROUND AND AIMS: We evaluated the possible predictive role of C-reactive protein (CRP) on the immediate postoperative outcome after femoropopliteal bypass surgery for critical leg ischaemia (CLI). MATERIAL AND METHODS: 138 patients with CLI who underwent 143 femoropopliteal reconstructions. RESULTS: The immediate postoperative period secondary patency rate was 87%, leg salvage rate was 94%, and survival rate 97%. Nine patients (6.3%) had 30-day postoperative major amputation, three of them despite a patent bypass graft because of progression of foot infection. The preoperative serum concentration of CRP was the only predictor of postoperative major amputation (p = 0.004; for an increase of 10 mg/l: OR, 1.188; CI 95%, 1.059-1.332). The median preoperative serum concentration of CRP among patients who did not have major amputation was 13.0 mg/l (range, 1-185), whereas it was 47.5 mg/l (range, 5-168) among those who had amputation after bypass graft occlusion, and 115.0 mg/l (range, 34-222) among those who had amputation despite a patent bypass graft (p = 0.008). CONCLUSIONS: CRP may be a useful marker in risk stratification for postoperative amputation in patients undergoing femoropopliteal bypass surgery for CLI.
