Venous Thromboembolism Prophylaxis After Spontaneous Intracerebral Hemorrhage

Abstract

Background: 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. Review Summary: 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. Conclusions: 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.
