Objectives – To evaluate safety, clinical feasibility, and outcome of intraventricular (IVen) administration of recombinant tissue plasminogen activator (rt‐PA) in patients with intraventricular hemorrhage (IVH).
Materials and methods – Forty‐eight patients with IVH who received IVen rt‐PA were compared with 49 age‐, sex‐, Glasgow Coma Scale score‐, and Intracerebral Hemorrhage score‐matched control patients. Patients with IVH of aneurysmal or arteriovenous malformation origin were excluded. External ventricular drainage was inserted as soon as baseline CT was performed and rt‐PA was administered within 12 ± 1 h after the ictal onset.
Results – The outcome after 3 months was evaluated using the modified Rankin Scale (mRS). In addition, Glasgow Outcome Scale (GOS) and mortality were assessed. A good outcome, defined as mRS 0–3, was detected in 27% of patients from the control group vs 58% of patients in the IVen group; P = 0.003. GOS as other outcome scale yielded a significant difference between groups: 20% in the control group, vs 54% in the IVen group; P = 0.001. A statistically significant decrease in mortality was observed in the IVen group: 30% in the control vs 10% in IVen group; P = 0.003. No one patient died because of a complication which could be directly attributed to the IVen thrombolytic therapy.
Conclusions – IVen administration of rt‐PA seems to be safe in cases of IVH. This pilot study shows that it may be associated with better outcomes. Further studies and clinical randomized trials are needed to establish indications and IVen administration protocols.
