Surgical Technique for Tentorium Resection and Oculomotor Nerve Mobilization during Internal Carotid Artery-Posterior Communicating Artery Aneurysm Clipping

Introduction: Internal carotid artery-posterior communicating artery aneurysms (ICPCANs) are occasionally located under the anterior petroclinoid fold (tentorium). The tentorium must be resected to achieve safe and secure clipping of the ICPCAN. The surgeon performing the procedure must be careful not to damage the oculomotor nerve, which is usually located behind the aneurysm, to ensure that the patient's oculomotor function is preserved. In this article, we presented a surgical technique for the tentorium resection and oculomotor nerve mobilization during an ICPCAN clipping intervention. Additionally, the clinical features of the patients who underwent the procedure have been described.
