Purpose of review: Recent success in preliminary clinical studies evaluating various forms of minimally invasive surgery for spontaneous intracerebral hemorrhage (ICH) has renewed interest in the surgical treatment of this disease process.
Recent findings: In December of 2016, phase 2 of the Minimally Invasive Surgery Plus Rt-PA for ICH Evacuation (MISTIE) study demonstrated that this form of stereotactic thrombolysis safely reduces clot burden and may improve functional outcome 6 months after injury. A smaller arm of this study, the Intraoperative Stereotactic Computer Tomography-Guided Endoscopic Surgery (ICES) study, also demonstrated feasibility and good functional outcome for endoscopic minimally invasive evacuation. Early-phase clinical studies evaluating various forms of minimally invasive surgery for intracerebral hemorrhage evacuation have shown safety and feasibility with a preliminary signal towards improved functional long-term outcome. Results from phase 3 studies addressing various minimally invasive techniques are imminent and will shape how intracerebral hemorrhage is treated.
