Abstract

Abstract Cavernous malformations (CM) are benign, low-flow vascular lesions that account for 5% - 13% of all cerebrovascular malformations. Surgery remains the most important treatment strategy, and many different approaches have been developed. We present here our institutional experience with 68 cases using a transcortical neuronavigation approach with some technical nuances to improve navigation accuracy during resection. The technique and clinical outcomes are discussed, with a specific focus on seizure sequels. Demographic data were collected, along with information on clinical and seizure characteristics at presentation, localization and size of CM, presence of multiple localizations, evidence of recent CM-related bleeding on MRI, intervention features, postoperative complications, prescription of anti-epileptic drugs at discharge and seizure outcome. We assume that surgery through a narrow well-defined working corridor would limit brain exposure and manipulation, and hence could significantly affect not only general complications, but also seizure control. The technique is feasible and associated with relatively low rates of minor and major procedure-related complications. It is also a valid method for surgeons in training since the trajectory is planned preoperatively with a senior consultant and the working corridor always follows the catheter, which directly leads to the cavernoma.
