We aimed to investigate the effect of the time interval from the clinical presentation of a thrombosed dialysis access graft to intervention on procedure success.
Records from two academic institutions for patients who underwent percutaneous thrombectomy of occluded surgical hemodialysis graft access sites in interventional radiology from 2006 to 2011 were reviewed retrospectively. The following data were recorded: gender, age, time and date of the initial request for a thrombectomy and the procedure, age of the surgical access, angiographic outcome, and clinical outcome (successful or unsuccessful postinterventional dialysis). Univariate and multivariate logistic regression were used to evaluate whether the time to intervention significantly affected the study endpoint.
In total, 268 percutaneous thrombectomies were performed in 139 patients. Of these 224 (83.5%) were categorized as successful and 44 (16.4%) as unsuccessful. The time to intervention was 19.9±30.1 vs. 22±35 hours for successful and unsuccessful procedures, respectively. The difference between the two was not significant, and there were also no significant differences in covariate distributions between successful and unsuccessful outcomes.
During the first 72 hours following clinical presentation of a thrombosed dialysis access graft, time to intervention may be considered independent of procedure outcome.
我们旨在研究从血栓形成的透析通路移植物临床表现至干预的时间间隔对手术成功率的影响。
回顾性分析了2006年至2011年期间在两家学术机构接受介入放射学经皮血栓切除术治疗闭塞性外科血液透析移植物通路部位患者的记录。记录了以下数据：性别、年龄、首次请求血栓切除术及手术的时间和日期、手术通路的使用时长、血管造影结果以及临床结果（介入后透析成功或失败）。采用单因素和多因素逻辑回归分析来评估干预时间是否显著影响研究终点。
总共对139例患者进行了268次经皮血栓切除术。其中224例（83.5%）手术成功，44例（16.4%）手术失败。成功和失败手术的干预时间分别为19.9±30.1小时和22±35小时。两者之间的差异不显著，成功和失败结果的协变量分布也无显著差异。
在血栓形成的透析通路移植物临床表现后的最初72小时内，干预时间可被视为与手术结果无关。
