Abstract 13140: Long-Term Outcomes for Primary Stenting in Complex Iliac Artery Disease Classified According to Trans-Atlantic Inter-Society Consensus (TASC)-II
Introduction: Although advances in endovascular techniques have provided new options in the treatment of complex lesions, few reported the long-term outcome in the patients underwent endovascular therapy for Trans-Atlantic Inter-Society (TASC)-II C/D lesion in iliac artery.
Hypothesis: We assessed the hypothesis that endovascular therapy for TASCII C/D iliac lesion was safe and good result with primary stenting. The purpose of this study was to evaluate outcomes of endovascular interventions on TASCII groups in iliac disease.
Methods: Retrospective analysis of 436 patients who underwent iliac arterial stent placement revealed 650 stents were placed in 535 limbs. Iliac lesions of patients were classified according to the TASCII classification on initial angiography. Analysis was performed based on the number of treated limbs. The primary patency (defined as freedom from restenosis or repeat revascularization) of individual TASCII stages were analyzed by Kaplan-Meier methods and were compared by the log rank test.
Results and Conclusions: The primary technical success rate was achieved in 99.8% with an overall complication rate of 2.8%. The number of limbs in each TASCII group was: TASCII A (288), TASCII B (138), TASCII C (54), and TASCII D (55). The 1 and 3 year primary patencies of the iliac stenting for TASC A were 98% and 94%; TASC B were 97% and 95%; TASC C were 94% and 94%; and TASC D were 98% and 95%, respectively. Four TASC groups were not statistically different for primary patency rates. In conclusion, primary stent placement for iliac artery disease was safe and acceptable among any TASCII category.
