Abstract:
Endovascular strategies for the treatment of critical infrageniculate peripheral arterial occlusive disease exist and are becoming the primary methodology for such lesions at many centers. Although technically feasible for experienced operators, the evidence to support this strategy for below the knee (BTK) interventions is still evolving. We studied the 6-month and 1-year outcomes of percutaneous transluminal angioplasty (PTA) alone, PTA with stenting, and excimer laser recanalization for BTK lesions in patients with critical limb ischemia. Between September 2002 and June 2005, 443 patients (355 Rutherford category 4, 82 category 5, 6 category 6) underwent intervention for 681 BTK lesions. Follow-up was performed at 6-month intervals after index intervention: limb salvage data were recorded and duplex ultrasonography was performed to measure the patency of treated areas. The primary patency and limb salvage rates of the entire population were 85.2% and 97.0% and 74.2% and 96.6% at 6 months and 1 year, respectively. Stratified for the treatment strategy (PTA alone in 79, PTA with stenting in 300 patients, and excimer laser in 64), 1-year primary patency rates were 68.6%, 75.5%, and 75.4%, whereas the limb salvage rates were 96.7%, 98.6%, and 87.9% for each modality, respectively. Endovascular intervention will become the primary treatment for BTK lesions in patients with critical limb ischemia, with 1-year primary patency and limb salvage rates that compare favorably with published surgical data. Prospective, randomized, multicenter trials will be needed to further establish the role of endovascular intervention in this challenging patient group.
