    Abstract:
    BACKGROUND: This retrospective study evaluates the clinical outcomes of two heparin-bonded expanded polytetrafluoroethylene grafts, PROPATEN and ACUSEAL (W. L. Gore & Associates, Flagstaff, AZ, USA), for forearm loop vascular access. METHODS: We prospectively collected data on 60 patients who had undergone arteriovenous graft of the forearm loop type between January 2015 and December 2019. The primary endpoints were graft primary, assisted primary, and secondary patency rates. Secondary endpoints were time to first cannulation and postoperative complications. RESULTS: We enrolled 36 patients in the PROPATEN group (Group P) and 24 in the ACUSEAL group (Group A). All procedures were successful without any 30-day mortality. The median times to first cannulation were 16.5 days and 3 days in Groups P and A, respectively (p < 0.001). Mean follow-up periods were 13.4 ± 14.5 and 17.3 ± 9.3 months, respectively. Primary patency rates were 81% and 64%, respectively, at 6 months, and 60% and 40%, respectively, at 12 months (p = 0.008). Assisted primary patency rates were 96% and 83% at 6 months, 91% and 73% at 12 months, and 81% and 35% at 24 months (p = 0.044). Secondary patency rates were 96% and 81% at 12 months, and 87% and 62% at 24 months (p = 0.207). As a remote-period complication, disruption of the luminal layer of the graft was observed in two patients (4.2%) in Group A due to puncture and thrombectomy. CONCLUSIONS: Although the ACUSEAL graft offers the advantage of early cannulation, its primary and assisted primary patency outcomes were inferior to those of the PROPATEN graft. It is important for physicians to be aware of the different characteristics of each graft to select the best option for each patient.
