Objective: To analyze the risk factors of intracranial hemorrhage after implanting 125-iodine seeds for brain tumors. Methods: A total of 234 patients with intracranial tumors receiving treatment of 125-iodine seeds from March, 2013 to November, 2020 were retrospectively analyzed. Patients were divided into bleeding group and non-bleeding group according to whether postoperative intracranial hemorrhage was reported. Univariate and multivariate analysis was performed by logistic regression to determine the independent risk factors of intracranial hemorrhage. Result: A total of 22 cases (9.4%) reported postoperative intracranial hemorrhage in 234 patients treated with 125-iodine seeds. Univariate analysis showed that the type of tumor and the history of anti-angiogenic drug within one month were possible risk factors (P<0.1). Multivariate logistic regression analysis showed that anti-angiogenic drug within one month was the independent risk factor for intracranial hemorrhage (P<0.05). Conclusions: The application of anti-angiogenic drugs within one month is the independent risk factor of intracranial hemorrhage with 125-iodine seeds for the treatment of brain tumors.
目的： 分析颅内肿瘤125I粒子治疗并发颅内出血的危险因素。 方法： 回顾性分析青岛大学附属医院介入医学中心2013年3月至2020年11月行颅内肿瘤125I粒子治疗患者的临床资料，共计234例，按照术后是否并发颅内出血将患者分为出血组和未出血组。应用二分类logistic回归分析对纳入的因素进行单因素分析，再将有意义的因素纳入多因素logistic回归分析确定颅内肿瘤125I粒子治疗并发颅内出血的独立危险因素。 结果： 234例接受125I粒子治疗的颅内肿瘤患者术后并发颅内出血者共计22例，颅内出血发生率为9.4%。单因素分析显示：肿瘤类型、近1个月内抗血管生成药物治疗史可能是颅内肿瘤125I粒子治疗并发颅内出血的影响因素（P<0.1）。多因素logistic回归分析显示，近1个月内抗血管生成药物治疗史是颅内肿瘤125I粒子治疗并发颅内出血的独立危险因素（P<0.05）。 结论： 近1个月内应用抗血管生成药物治疗是125I粒子治疗并发颅内出血的独立危险因素，评估上述指标对125I粒子治疗并发颅内出血有重要的临床意义。.
