目的 评估初次切割球囊血管成形术治疗自体透析瘘静脉狭窄的技术成功率和通畅率。 方法 41 名患者（26 名男性，15 名女性；年龄范围 26-82 岁，平均年龄 59 岁）在 3 个机构由 3 名主要操作者进行了 50 次（9 名患者重复手术）初次切割球囊 (PCB) 血管成形术。适应症为原发性狭窄 21 例，复发性病变 15 例，未成熟瘘管 5 例。17 例单独使用 PCB，33 例随后使用更大的标准球囊。随访内容包括超声、血流分析和尿素减少率，随访时间2～30个月，平均14个月。结果技术成功率为98%。所有手术都相对无痛。两块 PCB 爆裂，四块 PCB 泄漏，但没有造成任何发病。最后一次随访时，19 个瘘管仍然有效。使用 Kaplan-Meier 分析，6、12 和 24 个月时的初次通畅率分别为 88%、73% 和 34%，初次辅助通畅率分别为 90%、75% 和 50%。 结论 PCB 血管成形术技术成功率高，并发症发生率低。 PCB血管成形术的长期通畅率良好，与其他系列相比具有优势。
Aim To evaluate the technical success and patency rates following primary cutting balloon angioplasty for venous stenoses in native dialysis fistulas.Methods Forty-one patients (26 men, 15 women; age range 26-82 years, average age 59 years) underwent 50 (repeat procedures in 9 patients) primary cutting balloon (PCB) angioplasty procedures in three institutions by three primary operators. The indication was primary stenosis in 21 patients, recurrent lesions in 15, and immature fistulas in 5. A PCB was used alone in 17 cases, but was followed by a larger standard balloon in 33 cases. Follow-up included ultrasound, flow analysis and urea reduction ratio, and ranged from 2 to 30 months (mean 14 months).Results The technical success rate was 98%. All procedures were relatively painless. Two PCBs burst and 4 leaked, but without causing any morbidity. Nineteen fistulas were still working at last follow-up. Primary patency rates at 6, 12, and 24 months using Kaplan-Meier analysis were 88%, 73%, and 34%, respectively, and the primary assisted patencies were 90%, 75%, and 50%, respectively.Conclusion PCB angioplasty has high technical success and low complication rates. The long-term patency rates are favorable for PCB angioplasty and compare favorably with other series.
