【摘要】 目的比较高压球囊与普通外周球囊治疗前臂自体动静脉瘘狭窄1年后的通畅率。方法将40例前臂自体人工动静脉瘘狭窄的患者,随机分成高压球囊组和普通球囊组,每组20例。对患者行经皮静脉血管成形术,随访1年患者的手术后通畅率和瘘管的流量。结果与普通球囊组比较,高压球囊组患者的手术成功率高(95.00%vs 80.00%),1年后的通畅率高(30%vs 10%),差异均有统计学意义(P=0.033,P=0.04)。结论高压球囊在治疗前臂自体人工动静脉瘘狭窄,较普通外周动脉球囊长期通畅率和手术成功率有明显优势。更多还原

【Abstract】 Objective To compare primary patency rates achieved by conventional balloon angioplasty and high-pressure balloon angioplasty in treatment of stenosis of arteriovenous fistulae(AVF) in patients with hemodialysis. Methods Forty hemodialysis patients with native AVF stenosis were randomly assigned to undergo high-pressure balloon angioplasty(n = 20) or conventional balloon angioplasty(n = 20). Patients were followed up for 1 year,the duration of patency and the flow rate of fistula were compared between two groups. Results Technical success rate of high-pressure balloon angioplasty was higher than that of conventional balloon angioplasty(95. 0% vs 80. 0%,P = 0. 033).The 1-year patency rate of high-pressure balloon angioplasty was higher than that of conventional balloon angioplasty(30% vs 10%,P = 0. 04). Conclusion Compared with conventional balloon angioplasty,high-pressure balloon angioplasty can improve success rate of surgery and long-term patency rate in treatment of stenosis in hemodialysis arteriovenous fistulae.更多还原
