OBJECTIVE To explore which intraventricular fibrinolytic agent - urokinase (UK) or recombinant tissue plasminogen activator (rt-PA) - combined with extraventricular drainage (EVD) is most suitable for patients with spontaneous intraventricular hemorrhage (IVH). PATIENTS AND METHODS We searched PubMed, MEDLINE, OVID, Embase, and Cochrane Library databases for relevant articles and assessed their quality and extracted statistical analyses using Stata 13.0 and
Revman 5.3 software. RESULTS Compared with EVD alone, EVD combined with an agent causing intraventricular fibrinolysis (IVF) improved the survival and prognosis of patients with IVH. Regarding the patients' survival rates and prognoses, the treatments, from best to worst results were EVD + UK, EVD + rt-PA, EVD alone. The proportion of patients with serious disability also increased with these treatments, however, with the highest to lowest proportions being EVD + rt-PA, EVD + UK, EVD alone. In addition, EVD + IVF was associated with a higher risk of intracranial rebleeding (from lowest to highest incidence: EVD alone, EVD + rt-PA, EVD + UK). Finally, EVD + UK is associated with an increased risk of potential intracranial infection (from lowest to highest incidence: EVD + rt-PA, EVD alone, EVD + UK). CONCLUSIONS EVD + UK may be the best approach to improving patients' survival rate and prognosis. However, it also presents the highest risk of intracranial infection and rebleeding. EVD + IVF increased the proportion of patients with serious disability.
