Thrombolytic Evacuation of Intracerebral and Intraventricular Hemorrhage

Intracranial hemorrhage (ICH) accounts for 10-15?% of all strokes, however it causes 30-50?% of stroke related mortality, disability and cost. The prevalence increases with age with only two cases/100,000/year for age less than 40?years to almost 350 cases/100,000/year for age more than 80?years. Several trials of open surgical evacuation of ICH have failed to show clear benefit over medical management. However, some small trials of minimal invasive hematoma evacuation in combination with thrombolytics have shown encouraging results. Based on these findings larger clinical trials are being undertaken to optimize and define therapeutic benefit of minimally invasive surgery in combination with thrombolytic clearance of hematoma. In this article we will review some of the background of minimally invasive surgery and the use of thrombolytics in the setting of ICH and intraventricular hemorrhage (IVH) and will highlight the early findings of MISTIE and CLEAR trials for these two entities respectively.
