To present operative details and clinical follow-up of a series of patients with thoracic disk herniation treated with the minimally invasive technique of thoracic microendoscopic diskectomy (TMED). ⋯ TMED is a safe and effective minimally invasive posterolateral approach for the treatment of thoracic disk herniations that lacks the morbidity associated with traditional approaches.

In preparation for a multicenter study, a protocol was written on how to perform surgical targeting of the bed nucleus of the stria terminalis, based on the lead implantation experience in patients with treatment-refractory obsessive-compulsive disorder (OCD) at the Universitaire Ziekenhuizen Leuven (UZ Leuven). When analyzing the postoperative images, we were struck by the fact that the difference between the postoperative position of the leads and the planned position seemed larger than expected. ⋯ The cause of the posterior deviation could not be determined with certainty. The most likely cause was an increased mechanical resistance of the brain tissue along the trajectory when following the targeting protocol compared with the trajectories classically used for subthalamic nucleus or ventral intermediate nucleus of the thalamus stimulation.

Minimally invasive posterior atlantoaxial fusion: a cadaveric and clinical feasibility study.
Minimally invasive surgical (MIS) techniques have several potential advantages for the patient over open techniques, including decreased loss of blood, postoperative pain, and recovery time. We aimed to demonstrate atlantoaxial fusion by using the MIS techniques, shown previously in only two reports. A smaller operating corridor with MIS may increase difficulty of instrumentation placement and risk of instrumentation-related complications. ⋯ Minimally invasive atlantoaxial fixation is feasible and safe. Preoperative CT is paramount for preoperative evaluation of the vertebral artery anatomy in relation to C1/2 vertebra.

On the basis of the findings of the electrophysiological evaluation of vegetative state (VS) and minimally conscious state (MCS), the effect of deep brain stimulation (DBS) was examined according to long-term follow-up results. The results of spinal cord stimulation (SCS) on MCS was also examined and compared with that of DBS. ⋯ DBS for VS and MCS patients and SCS for MCS patients may be useful, when the candidates are selected on the basis of the electrophysiological inclusion criteria. Only 16 (14.9%) of the 107 VS patients and 15 (71.4%) of the 21 MCS patients satisfied the electrophysiological inclusion criteria.

To assess the outcome of stereotactic radiosurgery (SRS) for patients with benign skull base tumors and trigeminal-related facial pain. ⋯ Although SRS offers excellent radiographic tumor control for benign skull base tumors, durable relief of tumor-related trigeminal pain without medication was noted in only one-fourth of patients at last follow-up.
