ABSTRACT
PURPOSE: Percutaneous peripheral balloon angioplasty and stent insertion are used for the treatment of peripheral arterial obstructions and stenosis. In this study, we assessed the efficacy of peripheral balloon angioplasty and stent insertion in patients with peripheral arterial disease. METHOD: We performed a retrospective review of patients who underwent peripheral balloon angioplasty or stent insertion in obstructive or stenotic peripheral arterial lesions between July 2003 and November 2006. Follow-up study was performed using lower extremity multi-directional computed tomography (MDCT) or lower extremity angiography. Mean follow-up was 22.8 months. RESULT: A total of 30 patients (47 lesions) were treated. The mean age was 66.8 years, and the ratio of male to female patients was 29 to 1. Calf claudication was the most common chief complaint, and 19 patients had hypertension. Obstructive lesions were found in the common iliac artery (CIA) (18), external iliac artery (EIA) (11), superficial femoral artery (SFA) (15), and anterior tibial artery (ATA) (3). Peripheral balloon angioplasty was performed for 8 lesions, and stent insertion was performed for 39 lesions. Re-stenosis occurred in 9 lesions (3 in the CIA, 5 in the SFA, 1 in the ATA) during follow-up. CONCLUSION: Peripheral balloon angioplasty and stent insertion are useful modalities for the treatment of obstruction or stenosis in lower extremity peripheral arteries. Close follow-up is necessary to improve long-term outcomes.
