Far lateral approach for resection of lower pontine cavernous malformation
1Department of Neurological Surgery, University of Miami, Miami, Florida; and 2Department of Neurological Surgery, University of Pittsburgh Medical Center, Pittsburgh, Pennsylvania Abstract In this 3D video we review the case of a lower pontine cavernous malformation in a 31-year-old man who presented with hemiparesis and an abducens palsy. The cavernous malformation was completely resected through a far lateral approach and a peritrigeminal brainstem entry zone, with a significant improvement in the patient’s hemiparesis. The relevant anatomy is reviewed in detail through multiple anatomical brainstem dissection specimens, as well as high-definition fiber tractography images. The rationale for the approach is analyzed relative to other possible options, and a number of technical pearls are provided.
