The use of an arteriovenous (AV) graft for hemodialysis is associated with a relatively high rate of thrombosis. Unfortunately, the urgent thrombectomy is not always readily available. Our aim was to investigate a possible association between the timing of thrombectomy and the patency rates of AV grafts.
A retrospective single-center study on patients who underwent thrombectomy of clotted AV grafts was conducted. According to the time of thrombectomy, all patients were divided into 4 groups.
Primary graft patency at 6 months after thrombectomy was 28.3%, with no significant difference between the study groups (P = .161). Secondary graft patency at 6 months was significantly worse in the group that underwent thrombectomy between the third and fifth days than in the whole cohort: 15.4% versus 45.6% (P = .038).
Timing of thrombectomy of a clotted AV graft may have a significant impact on the graft survival.
动静脉（AV）移植物用于血液透析时血栓形成率相对较高。不幸的是，紧急血栓切除术并非总能轻易获得。我们的目的是研究血栓切除术时机与AV移植物通畅率之间可能存在的关联。
对接受血栓形成的AV移植物血栓切除术的患者进行了一项回顾性单中心研究。根据血栓切除术时间，将所有患者分为4组。
血栓切除术后6个月的初次移植物通畅率为28.3%，各研究组之间无显著差异（P = 0.161）。在第3天至第5天接受血栓切除术的组中，6个月时的二次移植物通畅率明显低于整个队列：分别为15.4%和45.6%（P = 0.038）。
血栓形成的AV移植物血栓切除术的时机可能对移植物存活有显著影响。
