摘要: Abstract Objectives : to identify risk factors for infrainguinal bypass occlusion and quantify the predictive value of data available before after surgery. Design prospective study 2650 patients who participated in a randomised trial oral anticoagulants or aspirin Materials methods were determined by univariate Cox regression analysis, entered multivariate analyses which distinguished two models: analysis from history clinical examination, completed radiological surgical second model. To compare information content models, receiver–operator characteristic (ROC) curves computed. Results all female gender, critical ischaemia, femorocrural grafting non-venous graft material independent factors. In with femoropopliteal bypasses poor run-off material, latter even supragenicular bypasses, The only significant factor grafts was use graft. contained first model poor, whereas had higher value. Conclusions major factor, above-knee is material. venous should be offered whenever possible.
