Permanent unilateral visual loss and orbital compartment syndrome following unilateral frontal craniotomy: illustrative case.

Background: Vision loss following supine craniotomy is an unexpected and devastating complication for the patient and the operating team. Postoperative vision loss (POVL) is commonly associated with cardiac, spinal, neck, and prone head surgeries, as they share common risk factors, such as a prone position, intraoperative hypotension, a longer anesthesia duration, and the use of vasopressors. Herein, the authors report a case of irreversible vision loss following a frontal craniotomy in the supine position together with a review of the literature.

The role of preoperative ultrasound in the management of peripheral nerve injuries.

Background: Peripheral nerve injury refers to any damage or trauma to the nerves located outside the central nervous system. Ultrasonography is a reliable, cheap, and minimally invasive method in clinical practice to give physicians useful information about nerve injury.

Objectives: to assess the power of ultrasound in determining the presence, localization, and extent of neural damage in patients with clinical evidence of peripheral nerve lesions before surgery.

Transoral vertebroplasty for the treatment of C2 painful metastatic lesions; evaluation and outcome.

Objective: A small number of studies supports vertebroplasty at the C2 vertebral body due to the documented technical challenges, the rarity of C2 osteolytic metastatic lesions, and the existence of potentially serious consequences linked to this particular anatomical area. Vertebroplasty, in such a situation, can be performed through a transoral, an anterolateral, or an open approach. All are supported by a limited number of studies with absence of a significant clinical trial assessing the efficacy, safety, and feasibility of vertebroplasty for the C2 vertebral body.

Multiple lessons learned from a single case: Complications from pineal germinoma management.

Background: Pineal tumors are uncommon tumors that affect <1% of adults, with 50% of them being germinomas. A combination of endoscopic third ventriculostomy (ETV) and tumor biopsy is usually used. Cerebral vasospasm in association with aneurysmal subarachnoid hemorrhage (aSAH) has been extensively studied.

Micro-Multileaf Collimator LINAC Radiosurgery for Vestibular Schwannomas.

Objective: This study evaluates the efficacy of linear accelerator (LINAC) radiosurgery using micro multi-leaf collimator technique (μMLC) in the treatment of a consecutive series of patients with vestibular schwannomas.

Patients And Methods: In this retrospective study, we enrolled 50 patients with non-neurofibromatosis type 2 vestibular schwannoma who were treated with μMLC LINAC-based SRS at University Hospital of Cologne, Germany. A minimum clinical follow-up of 24 months was conducted.

Intracranial ganglioglioma WHO I: results in a series of eight patients treated with stereotactic interstitial brachytherapy.

In this retrospective study we evaluated the efficacy of interstitial brachytherapy (IBT) using (125)Iodine seeds ((125)I) for intracranial ganglioglioma WHO I. Between October 1994 and March 2010, eight patients (m/f = 5/3, median age 30.4 years, age range 7-42.
