Nicotine Replacement Therapy for Smokers with Acute Aneurysmal Subarachnoid Hemorrhage: An International Survey.

Introduction: Smoking prevalence is twice as high among patients admitted to hospital because of the acute condition of aneurysmal subarachnoid hemorrhage (aSAH) as in the general population. Smoking cessation may improve the prognosis of aSAH, but nicotine replacement therapy (NRT) administered at the time of aSAH remains controversial because of potential adverse effects such as cerebral vasospasm. We investigated the international practice of NRT use for aSAH among neurosurgeons.

Operative Anatomy of the Skull Base: 3D Exploration with a Highly Detailed Interactive Atlas.

 We evaluated the usefulness of a three-dimensional (3D) interactive atlas to illustrate and teach surgical skull base anatomy in a clinical setting.  A highly detailed atlas of the adult human skull base was created from multiple high-resolution magnetic resonance imaging (MRI) and computed tomography (CT) scans of a healthy Caucasian male. It includes the parcellated and labeled bony skull base, intra- and extracranial vasculature, cranial nerves, cerebrum, cerebellum, and brainstem.

Papillary meningioma: a rare cause of massive supratentorial intracerebral hemorrhage.

Papillary meningioma (PM) represents a very rare histological subtype, which may present with massive intracerebral hemorrhage. Gross total tumor resection results in a lower recurrence rate and mortality. A 69-year-old man had been experiencing headache for 6 months.

Treatment of type II odontoid fracture in the elderly.

Odontoid fractures constitute the commonest cervical spinal fracture in the elderly. There are varied management approaches with paucity of robust evidence to guide decision-making. We review the case of a 92-years-old man with traumatic Grauer type II B odontoid fracture treated with anterior cannulated screw fixation.

Metastatic epidural spinal cord compression.

Up-to-date management for metastatic epidural spinal cord compression is based on appropriate scoring systems. In this case, separation surgery and stereotactic radiosurgery achieved an optimized outcome. A 75-year-old man had thoracic band-like pain, left lower limb weakness and difficulty ambulating for 6 weeks.

sEVD-smartphone-navigated placement of external ventricular drains.

Background: Currently, the trajectory for insertion of an external ventricular drain (EVD) is mainly determined using anatomical landmarks. However, non-assisted implantations frequently require multiple attempts and are associated with EVD malpositioning and complications. The authors evaluated the feasibility and accuracy of a novel smartphone-guided, angle-adjusted technique for assisted implantations of an EVD (sEVD) in both a human artificial head model and a cadaveric head.

Reduction of thromboembolic events in meningioma surgery: a cohort study of 724 consecutive patients.

Background: Meningiomas are associated with the highest postoperative rate of venous thromboembolic events (VTE) among all intracranial tumors. The aim of this study is to compare two entirely different VTE prophylaxis regimens in 724 consecutive patients undergoing meningioma surgery.

Methods: Two cohorts at a single institution treated with different regimens to prevent VTE were reviewed retrospectively.
