Prospective and retrospective data compared in patients with PTFE femoropopliteal bypass grafts.
Twenty-four patients with PTFE, femoropopliteal grafts were studied using two different methods. A prospective study was carried out as part of a clinical trial and later the same patients were identified as part of a retrospective study. Comparison of the details obtained independently showed marked differences in patients' ages, indications for surgery, angiographic runoff, operative detail, risk factors and subgroup patency.
