Objective:The objective of the current study was to demonstrate the threeyear outcome of the CERAB technique for the treatment of extensive aortoiliacocclusive disease (AIOD). Methods:Between February 2009 and July 2016, allpatients treated with the CERAB technique for AIOD were identified in the localdatabases of two centers and analyzed. Demographics and lesion characteristicswere scored. Follow-up (FU) consisted of clinical assessment, duplex ultrasoundand ankle brachial indices (ABI). Patency rates and clinically driven targetlesion revascularization (CD-TLR) were calculated by Kaplan-Meier analysis.Results: 130 patients (69 male and 61 female) were treated of which 68%patients were diagnosed with intermittent claudication and 32% suffered fromcritical limb ischemia. The vast majority (89%) were TASC-II D lesions and theremaining were TASC-II B and C (both 5%). Median follow-up was 24 months (range0-67 months). The technical success rate was 97% and 67% of cases wereperformed completely percutaneously. The ABI improved significantly from 0.65plusminus 0.22 preoperatively to 0.88 plusminus 0.15 after the procedure. The30-day minor and major complication rate was 33% and 7%. The median hospitalstay was 2 days (range 1-76 days). At 1 and 3-years FU 94% and 96% of thepatients clinically improved at least 1 Rutherford category (2% and 0%unchanged, 4% and 4% worsened). Limb salvage rate at 1-year was 98% and 97% atthree year follow-up. Primary, primary-assisted and secondary patency was86%/91%/97% at 1-year, 84%/89%/97% at 2-year and 82%/87%/97% at 3-year FU.Freedom from CD-TLR was 87% at 1-year and 86% at both 2 and 3-year FU.Conclusions:The CERAB technique is a safe and feasible technique for thetreatment of extensive aortoiliac occlusive disease with good three yearresults regarding patency and clinical improvement.
