AbstractDespite the lack of conclusive outcome data, surgical evacuation of large, symptomatic intracerebral hematomas (ICH) may be offered to patients on a case-by-case basis, aiming to prevent brain herniation, control intracranial pressure, relieve symptoms, and possibly facilitate or accelerate recovery.1-3 For deep ICH, minimally invasive techniques, which limit operative damage to healthy brain tissue, are generally preferred. Although new tube and endoscope-based techniques are currently being studied,4-7 those elaborate techniques are not widely available and often require special equipment and/or expensive disposable material. In this operative video (Video 1), we demonstrate a minimally invasive microsurgical approach for the evacuation of deep ICH, which relies on the use of careful preoperative planning, frameless stereotactic neuronavigation, and meticulous microsurgical technique. This technique involves small craniotomies, infracentimetric corticotomies, and physiologic subcortical white matter dissection, leading to very limited disruption of healthy brain tissue, akin to tube and endoscope-based procedures. We acknowledge that this technique or a modification thereof may currently be in use by other neurosurgeons in their practice.8 However, to the best of our knowledge, a step-by-step microsurgical video illustration of this technique has not been previously published. Although this technique can be broadly used by neurosurgeons, irrespective of the hospital setting, it would be particularly valuable in settings where expensive cutting-edge technology is not readily available.Copyright © 2021 Elsevier Inc.
