Abstract: Objective  To study the effect and complication of the promptly used type of artificial blood vessel for vascular access.  Methods  A total of 83 patients undergoing the surgery of artificial blood vessel implement in People’s Hospital of Ziyang during February 2019 to February 2022 were recruited as the research subjects. According to the diameter of outflow vein, they were divided into promptly used type of artificial blood vessel group (diameter of outflow vein >4mm, n=41) and expanded polytetrafluoroethylene (ePTFE) type of artificial blood vessel group (diameter of outflow vein 3～4mm, n=42). They were followed up for 18 months after the surgery. Postoperative patency rate, effectiveness, complication and survival rate were compared between the two groups.  Results  The primary patency rates and secondary patency rates after the surgery for 6, 12 and 18 months had no statistical significances between promptly used type group and ePTFE type group (Primary patency rate: t=1.437, 0.609 and 0.595 respectively; P=0.231, 0.435 and 0.441 respectively. Secondary patency rate: t=2.108, 0.149 and 0.310 respectively; P=0.147, 0.699 and 0.578 respectively). The time of first puncture and the time of dialysis catheter removal after the surgery were shorter in promptly used type group than in ePTFE type group (t=78.386 and 21.491, P<0.001). Postoperative dialysis blood flow and artificial vessel utilization rate were similar between the two groups (t/χ²=0.214 and 0.988, P=0.831 and 0.320). The incidence of postoperative swelling and thrombosis were lower in promptly used type group than in ePTFE type group (χ²=24.418 and 7.540, P＜0.001 and 0.006). The survival rates of the patients after the surgery for 6, 12 and 18 months had no statistical significances between the two groups (χ²=1.037, 0.239 and 0.183 respectively; P=0.309, 0.625 and 0.668 respectively).   Conclusion  The promptly used type of artificial blood vessel for vascular access has the advantages of earlier puncture, higher patency rate, and lower risk of complications, and is worthwhile to be widely used clinically.
