To evaluate long-term primary and secondary patency results of drug-eluting balloon angioplasty for the treatment of juxta-anastomotic stenoses in distal radiocephalic arteriovenous fistulas.
Thirty-eight patients with juxta-anastomotic stenotic distal radiocephalic arteriovenous fistulas who underwent endovascular treatment with drug-eluting balloons between January 2014 and August 2016 in our interventional radiology department were included in this retrospective study. Color Doppler examination for follow-up was performed 15 days, 6 months, 12 months, 18 months, 24 months, 36 months, and 48 months after the procedure. Kaplan-Meier analysis was used to estimate primary and secondary patency rates.
Totally, 42 angioplasty with drug-eluting balloons was performed in 38 patients (20 men and 18 women; mean age 66.42 ± 12.01). Technical and clinical success rate was 100% (42/42). The mean follow-up period was 27.71 months ± 12.98 (range, 1-54 months). The estimated primary patency rates at 6 months were 94.7% (95% CI, 80.9%-99.0%), at 12 months were 81.2% (95% CI, 64.6%-91.4%), at 24 months were 60.7% (95% CI, 43.6%-75.7%), and at 48 months were 53.1% (95% CI, 36.5%-69.1%). The estimated secondary patency rates at 6 months were 97.3% (95% CI, 84.5%-99.8%), at 12 months were 86.5% (95% CI, 70.7%-94.8%), at 24 months were 69.0% (95% CI, 51.8%-82.4%), and at 48 months were 61.7% (95% CI, 44.6%-76.5%).
Drug-eluting balloon angioplasty is a useful, effective technique in dysfunctional radiocephalic fistulas due to juxta-anastomotic stenoses. We demonstrated remarkably high primary patency rates at 6, 12, 24, and 48 months.
评估药物洗脱球囊血管成形术治疗远端头静脉桡动脉吻合口后狭窄的长期一级和二级通畅率。
本回顾性研究纳入了 2014 年 1 月至 2016 年 8 月期间在我院介入放射科接受药物洗脱球囊血管成形术治疗的 38 例吻合口后狭窄的远端头静脉桡动脉动静脉瘘患者。术后 15 天、6 个月、12 个月、18 个月、24 个月、36 个月和 48 个月进行彩色多普勒随访检查。Kaplan-Meier 分析用于估计一级和二级通畅率。
38 例患者共行 42 例药物洗脱球囊血管成形术（20 例男性，18 例女性；平均年龄 66.42±12.01 岁）。技术和临床成功率均为 100%（42/42）。平均随访时间为 27.71±12.98 个月（范围 1-54 个月）。估计术后 6 个月一级通畅率为 94.7%（95%可信区间，80.9%-99.0%），12 个月为 81.2%（95%可信区间，64.6%-91.4%），24 个月为 60.7%（95%可信区间，43.6%-75.7%），48 个月为 53.1%（95%可信区间，36.5%-69.1%）。估计术后 6 个月二级通畅率为 97.3%（95%可信区间，84.5%-99.8%），12 个月为 86.5%（95%可信区间，70.7%-94.8%），24 个月为 69.0%（95%可信区间，51.8%-82.4%），48 个月为 61.7%（95%可信区间，44.6%-76.5%）。
药物洗脱球囊血管成形术是治疗吻合口后狭窄导致功能不良的头静脉桡动脉动静脉瘘的一种有用且有效的技术。我们在术后 6、12、24 和 48 个月时显示了非常高的一级通畅率。
