Aortoiliac angioplasty: is there a need for other types of percutaneous intervention?
In a retrospective study, the authors compared results in 81 patients who underwent 117 percutaneous transluminal angioplasty (PTA) procedures in the iliac arteries and 21 patients who underwent iliac artery atherectomy. Both groups were similar with respect to symptoms and risk factors. The overall technical success rates were 97.4% for PTA and 100% for atherectomy. The initial clinical success was 92.8% for PTA and 100% for atherectomy. Complications requiring surgery occurred in four of 117 (3.4%) PTA and one of 21 (4.8%) atherectomy procedures. The 2-year patency rate for PTA was similar to that achieved with atherectomy in a smaller patient population. These results indicate that atherectomy does not offer any definite advantage over conventional PTA for the routine management of iliac lesions and make it difficult to justify the additional expense and complexity of this technique.
