Efficacy and safety of endovascular treatment for femoropopliteal lesions of TASC II type C and D compared with TASC II type A and B in Korea

ObjectiveTo compare the long-term safety and clinical efficacy of endovascular treatment for TASC-II type C/D femoropopliteal lesion compared with TASC-II type A/B femoropopliteal lesion in Korea.MethodsA total of 179 limbs [TASC-II A/B femoropopliteal lesion (group I, n = 105 limbs) and TASC-II C/D (group II, n = 74 limbs)] were retrospectively analyzed from patients who underwent angioplasty with or without primary stent implantation between February 2008 and November 2012 at two medical centers in South Korea. The major adverse limb event was defined as a composite of target lesion revascularization, symptom relapse with abnormal ankle brachial index, and major amputation.ResultsImmediate procedural success rates were not significantly different (96.2% vs. 95.7%, p = 0.450). Although major adverse limb event, mainly driven by symptom relapse with abnormal ankle brachial index, were significantly higher in group II (p = 0.013), the incidence of major amputation was very low and similar in both groups.Co...
