Patients with spontaneous intracerebral hemorrhage (sICH) are at high risk for venous thromboembolism (VTE). The administration of mechanical and pharmacological VTE prophylaxis after sICH is important but challenging. The safety and efficacy of the optimal anticoagulant dose, timing, and type of VTE chemoprophylaxis in cases of sICH are still unclear, and clinicians are concerned that it may lead to cerebral hematoma expansion, which is associated with poor prognosis. Through this literature review, we aim to summarize the latest guidelines, recommendations, and clinical research progress to support evidence-based treatment strategies.
It has been proven that intermittent pneumatic compression can effectively reduce the risk of VTE and should be used at the time of hospital admission, whereas gradient compression stockings or lack of prophylaxis in sICH cases are not recommended by current guidelines. Studies regarding pharmacological VTE prophylaxis in patients with ICH were reviewed and summarized. Prophylactic anticoagulation for VTE in patients with ICH seems to be safe and was not associated with cerebral hematoma expansion. Meanwhile, the prophylactic efficacy of anticoagulation for pulmonary embolism seems to be more obvious than that of deep vein thrombosis in patients with ICH.
Clinicians should pay attention to the prevention and management of VTE after sICH. Intermittent pneumatic compression should be applied to patients with sICH on the day of hospital admission. After documentation of bleeding cessation, early initiation of pharmacological VTE prophylaxis (24 h to 48 h from sICH onset) seems to be safe and effective in pulmonary embolism prophylaxis.
自发性脑出血(sICH)患者发生静脉血栓栓塞(VTE)的风险很高。sICH后进行机械和药物性VTE预防很重要,但具有挑战性。sICH病例中VTE化学预防的最佳抗凝剂量、时机和类型的安全性和有效性仍不清楚,临床医生担心这可能导致脑血肿扩大,而这与预后不良相关。通过本次文献综述,我们旨在总结最新的指南、建议和临床研究进展,以支持基于证据的治疗策略。
已证实间歇性气动压迫可有效降低VTE风险,应在入院时使用,而目前的指南不建议在sICH病例中使用梯度压力袜或不进行预防。对关于ICH患者药物性VTE预防的研究进行了综述和总结。ICH患者VTE的预防性抗凝似乎是安全的,且与脑血肿扩大无关。同时,ICH患者中抗凝对肺栓塞的预防效果似乎比对深静脉血栓形成的预防效果更明显。
临床医生应关注sICH后VTE的预防和管理。应在入院当天对sICH患者应用间歇性气动压迫。在记录出血停止后,早期启动药物性VTE预防(sICH发病后24小时至48小时)在预防肺栓塞方面似乎是安全有效的。
