摘要: |
目的:探讨超声引导下置管溶栓联合高压球囊治疗动静脉内瘘急性闭塞的应用价值。
方法:回顾性分析在我院就诊经超声检查诊断为前臂动静脉内瘘急性闭塞的10例患者,病例组在超声引导下行置管溶栓联合高压球囊治疗。观察术后1个月、3个月、6个月的内瘘通畅率。对比分析病例组术前、术后及对照组的血管内径、峰值流速、血流量等数据。
结果:所有病例组均取得手术成功,术后6个月1例患者动静脉内瘘吻合口发生再狭窄;无患者出现再闭塞。病例组患者术后的血管内径、血流量较术前均有所增加,峰值流速有所减低,有统计学差异。
结论:超声引导下置管溶栓联合高压球囊治疗前臂动静脉内瘘急性闭塞有一定的可行性。 |

Abstract: |
Objective: To investigate the application value of ultrasound-guided transcatheter thrombolysis combined with high pressure balloon for acute occlusion in forearm arteriovenous fistulas (AVF) patients.
Methods: In the retrospective analysis, transcatheter thrombolysis with high pressure balloon dilatation were performed under ultrasound guidance in 10 patients with acute occlusion of forearm AVF as operation group. Meanwhile data of 20 patients whose AVF used commonly in hemodialysis as control group was collected. The patency rate of AVF at 1 ,3 ,6 months were studied. The vessel internal diameter and the peak systolic velocity (PSV), the blood flow of brachial artery were compared in the pre- operative and post-operative patients and control group.
Results: In 10 patients of operation group, ultrasound-guided transcatheter thrombolysis with high pressure balloon dilatation were successfully performed. After follow-up for 6 months, 1 patient had recurrent stenotic lesion, none of patients had recurrent occlusion. It showed a significant increase in the vessel internal diameter and blood flow and a significant decrease in PSV after the procedure.
Conclusons: Ultrasound-guided transcatheter thrombolysis with high pressure balloon is a feasible method for acute occlution in forearm AVF patients. |
