Trans-atlantic inter-society consensus II C and D Iliac lesions can be treated by endovascular and hybrid approach: A single-center experience

摘要

Purpose: To evaluate the long-term results of endovascular and hybrid treatment in patients with Trans-Atlantic Inter-Society Consensus (TASC) II type ''C'' and ''D'' aortoiliac lesions and to highlight, in contrast to TASC II guidelines, the importance to analyze individually the lesions of a single iliac axis. Methods: From January 2008 to December 2012, 50 patients with TASC II type C and D aortoiliac lesions underwent endovascular or hybrid treatment. In 38 patients (76%), the lesions were treated by endovascular approach, while in 12 (24%) patients surgical treatment was adopted. All patients underwent a postoperative surveillance program at 1, 3, and 6 months for the first year and every 6 months thereafter. Results: Technical success was achieved in all patients (100%). The postoperative complication rate was 4%. Primary patency rate was 93.3% at 1 year, 90.2% at 2 years, and 86.6% at 3 years. Cumulative secondary patency rate was 97.7% at 1, 2, and 3 years. Survival after 1 and 2 years was 94.8% and after 3 years was 91.1%. Limb salvage was 100% for the entire period of follow-up. Conclusions: In contrast to TASC II guidelines, the endovascular or hybrid treatment should be considered a valid approach for type C and D lesions. The hybrid treatment, in selected cases, is an effective method to improve the runoff, which plays a key role in the success of the treatment of multilevel stenoocclusive lesions. In TASC II C to D iliac lesions, a specific overview of each axis is necessary in order to select the most appropriate treatment.
