Case Reports
Endoscopic-Assisted Spinal Arachnoiditis Adhesiolysis and Placement of A Spinal Cysto-Subarachnoid Shunt.
Spinal arachnoiditis and associated arachnoid adhesions can cause debilitating neurological symptoms due to nerve root and spinal cord compression or tethering. Adhesiolysis using a microscopic approach has traditionally been used for this condition. This procedure has been further refined in recent years with the use of flexible endoscopes. ⋯ The present case report has highlighted the advantages of using a flexible endoscope to treat spinal arachnoiditis adhesiolysis and placement of a cysto-arachnoid shunt, including a smaller skin incision and extended visualization.

Vagus nerve stimulation (VNS) has become an increasingly popular procedure for the treatment of epilepsy and depression. Significant complications or side effects associated with VNS surgery may result from either the inadvertent direct injury to the vagus nerve as part of the surgical approach, placement of the electrode, or the concomitant stimulation of vagal efferent fibers. To mitigate these effects, the recognition of anatomic variants that may place the nerve at increased risk is necessary. ⋯ This is the first reported case of cervical vagus nerve duplication presented in the literature. Surgeons performing VNS implantations should be cognizant of this potential anomaly in order to avoid inadvertent injury to the nerve.

Carotid-cavernous fistulas are vascular malformations that pose a risk for intracranial hemorrhage when there is documented cortical venous drainage. When possible, treatment with transvenous embolization has become the technique of choice since the late 1990s.1,2 We present a case of a patient with a carotid-cavernous fistula treated with venous coil embolization via a jugular venous approach. The patient was a 59-year-old female with a history of intense headaches. ⋯ The patient was discharged at postoperative day 1 without complications. In this video, we narrate the important details of this alternative when a traditional route is inaccessible (Video 1). Informed consent was obtained for the case illustrated; however, neither Institutional Review Board nor patient consent is required for the report of a single case in which no identifiable patient information is shared.

Observational Study
Navigated 3-dimensional intraoperative ultrasound for spine surgery.
To integrate 3-dimensional (3D) intraoperative ultrasound (iUS) data in spinal navigation. ⋯ Using 3D-iUS can be successfully integrated in spinal navigation. Automatic registration applying low-dose iCT and non-linear image registration offers displaying preoperative images in the same orientation as the 3D-iUS scan, as well as visualizing segmented structures in the navigated 3D-iUS data. This greatly facilitates image interpretation. Navigated 3D-iUS provides a possibility for navigation updating and immediate online quality control.
