Awake Craniotomy in a Patient with Previously Diagnosed Post-Traumatic Stress Disorder.

Background: Awake craniotomy (AC) with brain mapping has been successfully used for the resection of lesions located in or near eloquent areas of the brain. The selection process includes a thorough presurgical evaluation to determine candidates suitable for the procedure. Psychiatric disorders including post-traumatic stress disorder (PTSD) are considered potential contraindications for this type of surgery because these patients may be less cooperative to tolerate AC. Here we present the management of a patient with PTSD who underwent an AC using a multidisciplinary team for removal of a dominant hemisphere low-grade insular glioma with speech, motor, and cognitive mapping.

Case Description: A 34-year-old right-handed male military veteran with a previous history of PTSD was scheduled for a left AC for resection of a low-grade insular glioma. He underwent preoperative neurocognitive assessment with a neuropsychologist and clinic visit with a neurosurgeon to characterize his PTSD and potential triggers, explain the procedure in a stepwise fashion, and address any concerns. The intraoperative environment was modified to minimize triggering stimuli, and an asleep-awake-asleep anesthetic protocol was followed. The patient tolerated the procedure well without any postoperative neurologic deficits including cognitive deficits. At 1-month follow-up, he denied any worsening of his PTSD symptoms and recalls the AC as a positive experience.

Conclusions: With a multidisciplinary team, adequate preoperative education, detailed clinical interview to identify triggers, and a controlled intraoperative environment, awake surgery can be carried out safely in a patient with PTSD.
