Resumen

Objective: Efficacy and safety of pharmacologic thromboprophylaxis after an episode of intracerebral hemorrhage remains unclear. This meta-analysis aimed at comparing the clinical outcomes of intracerebral hemorrhage patients with or without pharmacologic thromboprophylaxis. Methods: We performed a comprehensive literature review of PubMed to identified relevant studies. The primary and secondary endpoints included venous thromboembolism, deep venous thrombosis, pulmonary emboli, rebleeding, hematoma enlargement (defined as increase in hematoma volume of ≥33%), major disability (defined as modified Rankin score of 3–5), and death. Pooled outcomes were estimated by fitting random effects model with restricted maximum likelihood method. A total of 8 original studies including 3893 patients were analyzed. Result: Compared to the control group, pharmacologic thromboprophylaxis was associated with a lower risk of pulmonary embolism (odds ratio [OR]: 0.34, 95% CI: 0.15–0.80, P = 0.01). There was no significant difference in the risk of DVT (OR: 0.75; [95% CI: 0.37–1.53], P = 0.44) and VTE (OR: 0.65; [95% CI: 0.34–1.25], P = 0.20). Finally, anticoagulation was not associated with an increase rate of major disability (OR:1.36; [95% CI: 0.57 – 3.23], P = 0.48), rebleeding (OR: 0.35; [95% CI: 0.10–1.19], P = 0.09), hematoma enlargement (OR:1.34; [95% CI: 0.58–3.12], P = 0.49), or death (OR:0.90; [95% CI: 0.68–1.19], P = 0.46). Conclusion: Among patients with intracerebral hemorrhage, pharmacologic thromboprophylaxis was associated with a significant reduction in pulmonary embolism, without an increase in rebleeding or hematoma enlargement. The results of this meta-analysis need to be further validated in large scale clinical trials.
