Reconstruction of thoracolumbar structural stability is a formidable challenge for spine surgeons after vertebral body tumor resection. Various disadvantages of the currently used expandable or nonexpandable cages have limited their clinical applications. We sought to develop a novel prosthesis for clinical use and assess its preliminary clinical outcome in reconstruction of thoracolumbar structural stability after spinal tumor resection. ⋯ This novel prosthesis has many advantages in the reconstruction of height, lordosis, and alignment after thoracolumbar spinal tumor resection and has a favorable prospect for clinical application.

Deep Brain Stimulation of Nucleus Accumbens for Methamphetamine Addiction: Two Case Reports.
Methamphetamine (MA) addiction is one of the most prevalent socioeconomic and health problems worldwide. In recent years, deep brain stimulation (DBS) has increasingly been used for the treatment of addiction. ⋯ These case reports demonstrate that NAc-DBS maybe a possible treatment option for MA addiction.

In presurgical planning for intracranial meningiomas, the relationship between tumors and adjacent vasculature must be identified. The purpose of this study was to evaluate the usefulness of 3-dimensional digital subtraction angiography (3D-DSA) with dual-volume visualization (DVV). ⋯ 3D-DSA with DVV may be useful for preoperative planning by allowing the surgeon to identify the relationship between a tumor and peritumoral vasculature before meningioma surgery. Young neurosurgeons with little experience may benefit most from this technique.

Bow hunter syndrome describes a mechanical compression of the vertebral artery on head rotation leading to reversible symptomatic vertebrobasilar insufficiency. Patients are commonly presenting with syncope, vertigo, dizziness, and visual disturbances. These symptoms usually resolve when the head is turned back into neutral position. Treatment options involve surgical decompression with or without fusion, bypass surgery, or endovascular intervention. ⋯ The reported case is unique as the bow hunter syndrome was further complicated by a pseudoaneurysm of the V3 segment. Surgical intervention proved to be an efficient treatment by stabilizing the affected segment in this patient.

To investigate the clinical characteristics of delayed remission (DR) of growth hormone (GH)-secreting pituitary adenoma after transsphenoidal adenectomy and inform follow-up treatments. ⋯ For certain groups of patients likely to achieve DR, additional treatments should not be performed early after surgery. Prolonged follow-up and close observation could help determine the therapeutic effect of surgery and guide postoperative treatments.
