ABSTRACT
BACKGROUND AND OBJECTIVES:
Percutaneous intervention has become an established technique in the treatment of peripheral arterial obstructive disease. This study was performed to evaluate the procedural success and long-term outcome of percutaneous intervention of the superficial femoral artery (SFA), and to determine the factors that influence the long-term outcome. SUBJECTS AND MEHTODS Eighty-eight consecutive lesions, in 76 subjects (mean age 65) with chronic lower limb ischemia and SFA obstruction, diagnosed with angiography were included in this study. The angiographic success was defined as residual stenosis <30% and the clinical success as an improvement by at least one clinical category. The clinical patency was defined as an absence of symptom recurrence and target lesion revascularization during the follow up period. The predictors of the outcome were also determined.RESULTS:
Balloon angioplasty only was performed in 39 lesions and thrombolysis only in 2, whereas stenting was performed in 47 lesions. Seventy four of the 88 attempts (84%) at recanalization were angiographically successful, while 73 (83%) experienced clinical improvement. The twelve month patency was 67%. Critical ischemia (versus intermittent claudication)(relative risk 4.2, p=0.020) and renal failure (relative risk 4.1, p=0.016) were independent negative predictors of the patency.CONCLUSION:
Percutaneous intervention of the SFA yielded a high procedural success rate, with an acceptable long-term outcome. Symptoms of critical ischemia and renal failure were predictive of a low long-term patency.
