Iliac and femoropopliteal lesions: evaluation of balloon angioplasty and classical surgery.
OBJECTIVE
The purpose of this study was to compare the characteristics of patients treated for atherosclerotic disease of the lower extremities with balloon angioplasty (BA) or classical surgery (CS) and to assess the outcome of both techniques.


METHODS
The records of 1364 patients who were treated with BA or CS for chronic lower limb ischemia between 1986 and 1993 were analyzed. Demographic features of patients, immediate and long-term survival, patency, and amputation rates were compared in both groups according to the level of the revascularization (iliac or femoropopliteal).


RESULTS
Patients undergoing BA were slightly younger (62.3 years versus 65.9 years for CS group; p = NS) and demonstrated symptoms consistent with less severe atherosclerotic disease (81% claudication in the BA group versus 48% in the CS patients; p < 0.001). At 30 days post-treatment in the BA and CS groups, respectively, there were 0.7% and 4% deaths (p < 0.01); 13% and 6% primary failures (p = 0.013); 13% and 6% secondary failures (p = 0.01); 0.3% and 12% general complications (p = 0.001); and 3% and 8%, nonvascular complications (p = 0.007). At the iliac level, in the angioplasty (n = 134 limbs) and surgery (n = 721 limbs) groups, respectively, the mean age was 57.6 and 63.7 years (p < 0.01), and claudication was present in 91% and 72%. Perioperative mortality was 0% and 1.9%. The 4-year survival rates were 95% and 88%; patency was 70% and 79%; and the amputation rates were 0% and 5%. At the femoropopliteal level, in the angioplasty (n = 138 limbs) and surgery (n = 656 limbs) groups, respectively, the mean age was 67.8 and 66.8 years (NS), and claudication was present in 69% and 28%. Perioperative mortality was 0.9% and 5.5%. The 4-year survival rates were 95% and 78%; and patency was 44% and 65%. At 2 years, the amputation rates were 6% and 12%.


CONCLUSIONS
Patients treated by BA were younger, especially in the iliac group, and had less symptomatic lesions than patients treated with surgery. Surgery achieved a better long-term patency at the cost of a higher immediate complication rate and mortality. Whenever technically feasible, BA may be the better choice for initial therapy in appropriate patients suffering from chronic lower limb ischemia.
