title: Open endarterectomy of the SPT segment: an experience.
abstract: The purpose of the study was to evaluate the results of open endarterectomy in short atherosclerotic occlusions of the SPT segment (superficial femoral, popliteal, and tibioperoneal arteries). Retrospectively, records from July 1999 to June 2004 of patients who underwent open endarterectomy of lower limb arteries were verified; 63 patients with 66 lesions had open endarterectomy of the SPT segment as a primary procedure. At the time of this study, there were 57 patients alive and six dead, with the cause of death being unrelated to the procedure. The patients had a mean age of 71 +/- 10.73 years, and there were 18 females and 45 males. All patients underwent routine follow-up at 1, 3, 6, and 12 months and yearly thereafter. Routine clinical examination and ultrasound were done to assess the outcome. The mean length of endarterectomized superficial femoral artery was 7.42 +/- 3.66 cm (range 2-15). The lesions involved were the superficial femoral, popliteal, and tibioperoneal arteries (SPT segment). The primary cumulative patency rate by means of life-table analysis was 48.8% at 5 years (mean 12.7 months, range 1-60). During follow-up, percutaneous transluminal angioplasty was necessary in nine patients, for a primary assisted patency rate of 85.1% at 5 years. The location of recurrent stenoses after endarterectomy was usually at one of the ends of the endarterectomy site. Once a preferred technique, endarterectomy is now overshadowed by bypass procedures. Our clinical experience suggests that, in a select group of patients with SPT segment occlusions, open endarterectomy is technically feasible and should be used in cases with insufficient vein for bypass grafting. It also can be used as an alternative to allow the long saphenous vein to be reserved for a bypass procedure in the future.
