Objective: The authors reviewed experience with patients harboring intracerebral hematoma (ICH) treated by stereotactic computed tomography (CT) guided thrombolysis and aspiration and evaluated feasibility, safety and prognostic factors of this procedure.
Methods: One hundred and ten patients with supratentorial ICH >25 ml without underlying structural etiology or coagulopathy were recruited. The patients with Glasgow Coma Scale (GCS) <5 were excluded. A catheter was directed stereotactically into the ICH under CT guidance. Hematoma aspiration was followed by instillation of urokinase. This was repeated every 6 hours until less than half of its initial volume remained. For analysis of prognostic factors, we classified them into two groups;good (Glasgow Outcome Scale (GOS) > or =4) and bad (GOS<4) prognosis group, and performed comparative analysis between two groups.
Results: Mean age was 59.8 years. The baseline hematoma size ranged from 15 to 72 mL. ICH volume reduced by an average of 74.2%. At 6 months after the procedure, 56 patients had achieved a good recovery, 29 patients were dependent, and 10 remained vegetative. Fifteen patients died in hospital. The main good prognostic factors were young age, small ICH volume, high GCS, absence of rebleeding, underlying disease and complications.
Conclusion: CT-guided thrombolysis and aspiration appears safe and effective in the reduction of ICH volume. Patients of ICH presenting with bad prognostic factors should require frequent radiological investigation and more meticulous procedure. Further studies are needed to assess optimal thrombolytic dosage and must include controlled comparisons of mortality, and disability outcome.
