摘　　要：目的探讨超声引导下动静脉内瘘扩张术后通畅率的影响因素。方法选取2018年1月—2023年11月在遵义市红花岗区人民医院行血液透析的动静脉内瘘狭窄患者96例,所有患者给予超声引导下动静脉内瘘扩张术治疗,在术后6个月进行内瘘通畅情况的判定,其中内瘘通畅80例(通畅组),内瘘狭窄16例(狭窄组),分析超声引导下动静脉内瘘扩张术后通畅率的影响因素。结果单因素分析显示,两组的动静脉内瘘内径、肱动脉血流量、年龄、透析时间、低镁血症比较,差异均有统计学意义(P均<0.05)。多因素Logistic回归分析显示,年龄≥60岁、有低镁血症、透析时间≥8个月、动静脉内瘘内径<1.80 mm与肱动脉血流量<150 mL/min为超声引导下动静脉内瘘扩张术后内瘘通畅的危险因素(OR=1.389、1.696、1.587、2.076、1.572,P均<0.05)。结论超声引导下动静脉内瘘扩张术后通畅率有待提高,年龄、透析时间、低镁血症、动静脉内瘘内径与肱动脉血流量为重要的影响因素,需要加强预防性管理。Objective To explore the influence factors of the patency rate after ultrasound-guided arteriovenous fistula dilatation.Methods From January 2018 to November 2023,a total of 96 patients with arteriovenous fistula stenosis who underwent hemodialysis in People's Hospital of Honghuagang District in Zunyi City were selected.All patients were treated with ultrasound-guided arteriovenous fistula dilatation.The patency of the fistula was determined at 6 months after operation.Among them,80 cases of internal fistula patency(patency group),16 cases of internal fistula stenosis(stenosis group),and the influencing factors of the patency rate after ultrasound-guided arteriovenous fistula dilatation were analyzed.Results Univariate analysis showed that there were significant differences in arteriovenous fistula diameter,brachial artery blood flow,age,dialysis time and hypomagnesemia between the two groups(all P<0.05).Multivariate Logistic regression analysis showed that age≥60 years,hypomagnesemia,dialysis time≥8 months,arteriovenous fistula diameter<1.80 mm and brachial artery blood flow<150 mL/min were risk factors for patency of internal fistula after ultrasound-guided arteriovenous fistula dilatation(OR=1.389,1.696,1.587,2.076,1.572,all P<0.05).Conclusion The patency rate after ultrasound-guided arteriovenous fistula dilatation needs to be improved.Age,dialysis time,hypomagnesemia,internal diameter of arteriovenous fistula and brachial artery blood flow are important influencing factors,and preventive management needs to be strengthened.
