Several postoperative complications related to lumbar microdiscectomy have been reported, including cauda equina syndrome. However, to the best of our knowledge, postoperative cauda equina syndrome resulting from dural sac shift with engorgement of the epidural venous plexus is yet to be reported. ⋯ We report a rare case of postoperative cauda equina syndrome due to dural sac shift and discuss the nascent mechanism of the dural sac shift focusing on anatomic features of the dural sac. We also propose laminoplasty as an option to treat dural sac shift with engorgement of the epidural venous plexus.

Most aneurysms originating from the clinoidal segment of the internal carotid artery (ICA) are nowadays managed conservatively, treated endovascularly with coiling (with or without stenting) or flow diverters. However, microsurgical clip occlusion remains an alternative. This video demonstrates clip occlusion of an unruptured right carotid cave aneurysm measuring 7 mm in a 39-year-old woman. ⋯ This case demonstrates the importance of anterior clinoidectomy and thorough distal dural ring dissection for effective clipping of carotid cave aneurysms. Control of venous bleeding from the cavernous sinus with fibrin glue injection simplifies the dissection, which should minimize manipulation of the optic nerve. Knowledge of this anatomy and proficiency with these techniques is important in an era of declining open aneurysm cases.

Gross total resection for malignant brain neoplasms is challenging owing to the heterogeneity of these lesions and infiltration in eloquent areas. Gross total resection is a very important part of treatment of these patients and is a crucial prognostic factor. Fluorescence-guided surgery is an important tool that improves the rate of total resection. ⋯ The use of fluorescence for malignant brain tumor resection increases the rate of gross total resection. It is an important tool that makes it possible to identify the lesion in areas where it looks like normal tissue under white light. This device is a low-cost option that has shown good results in our experience.

Central sensitization is abnormal and intense enhancement of pain mechanism by the central nervous system. Patients with central sensitization may be at higher risk of poor outcomes after spinal fusion. The Central Sensitivity Inventory (CSI) was developed to identify and quantify key symptoms related to central sensitization. ⋯ Preoperative CSI was associated with worse quality of life outcomes and increased length of stay after spinal fusions. CSI may be an additional measure in evaluating patients preoperatively to better predict successful spinal fusion outcomes.

A new sling technique in cervical radiculopathy due to vertebral artery loop compression : Case Report.
A 52-year-old woman had a 20-month history of progressive radiating pain in the left arm and numbness on C7 dermatome. ⋯ The patient's radiculopathic symptoms were improved and especially the aggravated pain by left head rotation subsided dramatically.
