J Neurosurg:海绵状血管瘤抗栓治疗的安全性

2019-08-08 杨中华 脑血管病及重症文献导读

脑海绵状血管畸形(Cerebral cavernous malformations,CCM),也称为海绵状血管瘤,是一种常见的颅内血管异常。其中1/5的患者超过1个 CCM,普通人群的发病率大约为0.1%-0.5%。排在颅内动脉瘤以后,CCM 是第二常见的脑血管畸形。

脑海绵状血管畸形(Cerebral cavernous malformations,CCM),也称为海绵状血管瘤,是一种常见的颅内血管异常。其中1/5的患者超过1个 CCM,普通人群的发病率大约为0.1%-0.5%。排在颅内动脉瘤以后,CCM 是第二常见的脑血管畸形。

由于心脑血管病属于高发性疾病,大量的患者长期服用抗血小板和/或抗凝药物,包括CCM 患者。这就提出了一个问题,诊断一个或多个 CCM 患者是否需要停止长期服用的抗栓药物(antithrombotic medication,ATM)。因为早期的研究样本量较小且随访时间短,以至于产生了矛盾的推荐意见,需要大型队列研究回答这个问题。

2019年6月来自瑞士的David Bervini等在JNS 上公布了他们的研究结果,以探讨合并1个或多个 CCM 患者长期服用 ATM 的 ATM 相关出血的风险。

该研究为单中心历经34年的回顾性研究,分析1个或多个 CCM 患者的人口学资料、临床、治疗和 ATM 相关信息。

共408例患者纳入到分析中,492个 CCM 诊断后进行了随访,共1616病灶-年。随访期间共37个 CCM(7.5%)发生了出血,CCM 相关症状性出血的每年总发生率为2.3%(95% CI,1.7% - 3.2%)。82例患者91个 CCM(16.8%)服用了 ATM。当按照 ATM 分层时,服用 ATM 患者病灶出血的每年发生率为0.7%(95% CI < 0.01% - 4.2%)未服用 ATM 者为2.5%。在多元描述性分析(P = 0.912)和生存分析(P = 0.145)中,未发现 ATM 与入院时(at presentation)CCM 相关出血风险增加有关,也没有发现 ATM 与 CCM-相关出血风险增加有关。

最终作者认为对于诊断为 CCM 的患者,使用 ATM 与出血风险增加无关。
