This study evaluated the technical success and long-term patency of endovascular treatment for occluded native hemodialysis fistulas caused by thrombotic occlusion (TO) and nonthrombotic occlusion (NTO).
This cohort included 96 consecutive occlusions (70 TOs and 26 NTOs) at the forearm. Clinical success and patency rates of endovascular treatment were calculated and compared between the TO and NTO groups.
Overall clinical success rate was 91.6%; and primary, assisted primary, and secondary patency rates at 1, 2, and 3 years were 49.6%, 30.7%, and 28.3%, respectively; 73.8%, 48.3%, and 48.3%, respectively; and 80.7%, 72.3%, and 66.2%, respectively. Clinical success rates of the TO and NTO groups were 91.4% and 92.3%, respectively. The 1-, 2-, and 3-year primary, assisted primary, and secondary patency rates of the TO group were 54.4%, 29.3%, and 25.6%, respectively; 70.7%, 49.4%, and 49.4%, respectively, and 78%, 68.8%, and 64,2%, respectively. Those of the NTO group were 38.9%, 32.4%, and 32.4%, respectively; 81.2%, 47.3%, and 40.6%, respectively; and 87%, 80.3%, and 70.2%, respectively. There were no significant differences between the clinical success and patency rates of the two groups.
Occluded native hemodialysis fistulas were restored with high frequency, without significant differences between clinical success and patency in the TO and NTO groups.
本研究评估了经腔内治疗血栓性闭塞（TO）和非血栓性闭塞（NTO）导致的自体动静脉内瘘闭塞的技术成功率和长期通畅率。
本队列纳入了 96 例前臂闭塞（70 例 TO 和 26 例 NTO）患者。计算并比较了 TO 和 NTO 组的腔内治疗临床成功率和通畅率。
总体临床成功率为 91.6%；1、2、3 年的原发通畅率、辅助原发通畅率和继发通畅率分别为 49.6%、30.7%和 28.3%、73.8%、48.3%和 48.3%、80.7%、72.3%和 66.2%。TO 和 NTO 组的临床成功率分别为 91.4%和 92.3%。TO 组的 1、2、3 年原发通畅率、辅助原发通畅率和继发通畅率分别为 54.4%、29.3%和 25.6%、70.7%、49.4%和 49.4%、78%、68.8%和 64.2%。NTO 组分别为 38.9%、32.4%和 32.4%、81.2%、47.3%和 40.6%、87%、80.3%和 70.2%。两组的临床成功率和通畅率无显著差异。
自体动静脉内瘘闭塞经腔内治疗后可恢复通畅，TO 和 NTO 组的临床成功率和通畅率无显著差异。
