Efficacy and Safety of Proton Beam Therapy for Primary Optic Nerve Sheath Meningioma.

Purpose: Management of optic nerve sheath meningiomas (ONSM) remains challenging. Photon radiation therapy (PhRT) is the most common treatment for sight-threatening ONSM. Proton beam therapy (PBT) is less commonly used because it is more expensive and because there are questions about its efficacy specifically in relation to ONSM.

Microsurgical Transcranial Approach of 112 Paraoptic Meningiomas: A Single-Center Case Series.

Background: Predictors of visual outcomes after optic nerve decompression are controversial.

Objective: To identify the predictors of poor visual outcomes after surgery of meningiomas responsible of a compressive optic neuropathy.

Methods: We focused on paraoptic meningiomas (POMs), which gathered tuberculum sellae meningiomas (TSMs) and anterior clinoid meningiomas (ACMs) responsible for visual impairment or threatening visual function, that underwent surgery at our institution between January 2009 and December 2015 and analyzed the clinical and radiological findings of our patients.

Skull base surgery for pediatric parameningeal sarcomas.

Background: Localized pediatric parameningeal sarcomas are usually treated exclusively by chemotherapy and radiotherapy. In this location, surgery is complicated but sometimes attempted to improve local control.

Methods: A retrospective bicentric study was conducted to examine its place with particular reference to acute and long-term morbidity.

Latissimus dorsi free flap reconstruction of anterior skull base defects.

Introduction: Surgery of extensive skull base tumour results of a defect of soft and hard tissue and dura. Free flap reconstruction provides tissue to restore the defect and separate the intracranial content from the bacterial flora of the nasal fossae. Vertical and transverse rectus abdominis myocutaneous free flap are usually used.

Neck-bridge device for combined endovascular and surgical treatment of a giant anterior communicating artery aneurysm.

We report the case of a 58-year-old man with a giant partially thrombosed anterior communicating artery aneurysm, which presented with mass effect. Our treatment strategy consisted of endovascular aneurysm circulatory exclusion prior to surgical resection. To do so, we first occluded both the two A1 segments and the aneurysm neck with a neck-bridge device to prevent further coil migration within the aneurysm sac.

Carotid rupture during stent-assisted aneurysm treatment.

We report the case of a supraclinoid carotid rupture during the delivery of a balloon-expandable stent in a 59-year-old patient with incidental paraclinoid berry aneurysms for whom stent-assisted coiling was planned. The deployment of the stent resulted in immediate rupture of the artery. We describe the emergent management of this complication with prolonged balloon inflation to occlude the site of rupture, a treatment that led to the discharge of the patient 2 weeks later without any sequelae.

Clinical and hemodynamic responses to balloon test occlusion of the straight sinus: technical case report.

Objective And Importance: Surgical sacrifice of the straight sinus may be performed during intracranial tumor resection. Sacrifice of the straight sinus is associated with an unpredictable risk of venous infarction. We describe a patient with a falcine meningioma who underwent endovascular balloon test occlusion of the straight sinus before surgical resection.
