Supracerebellar-Infratrochlear Approach for Midbrain Cavernoma: 3-Dimensional Operative Video.
Gravity retraction is an underutilized adjunct in neurosurgery. Gravity is gentler than retractor blades; it does not cause brain edema or injury, and it tends to open natural subarachnoidal plans to deep lesions.1-3 A good example of this is the supracerebellar infratrochlear approach4-7 in semisitting position for resection to a midbrain cavernous malformation. This approach was selected because the cavernous malformation was 1 mm under the lateral mesencephalic sulcus. The procedure was developed with the use of transesophageal ultrasound and physiological neuromonitoring. We present a 3-dimensional video of this surgery with all the tricks and details used in the procedure. The patient consented to the procedure and to publication of the photos and surgical video.
