Neuroendoscopic fenestration for entrapped temporal horn after surgery :report of 3 cases
The postoperative ventricular adhesion after resection of CNS tumors may obstruct physiological CSF circulation and cause temporal horn entrapment. The surgical goal is to restore physiological flow of cerebrospinal fluid (CSF). The authors reviewed their database to report their experience with endoscopic fenestration for treating entrapped temporal horn caused by atrial adhesions. All endoscopic operations performed from February 2015 to December 2016 were reviewed. Three patients developed temporal horn entrapment after tumor resection. (Source: World Neurosurgery)

Accuracy of susceptibility weighted imaging and dynamic susceptibility contrast MRI for differentiating high-grade glioma from primary CNS lymphomas: a meta-analysis
and Purpose: It is always a great challenge to distinguish high-grade glioma (HGG) from primary central nervous system lymphoma (PCNSL). We conducted a meta-analysis to assess the performance of dynamic susceptibility contrast (DSC) and susceptibility weighted-imaging (SWI) in differentiating HGGs from PCNSLs.

Making Anatomical Preparations of the Human Brain Using Colored Silicone for Vascular Perfusion Staining (Technical Description)
Thorough understanding of the central nervous system anatomy is a fundamental part of a neurosurgeon ’s training. Development of novel neurosurgical approaches and optimization of existing ones directly depend on the comprehensive study of topographic anatomy of the head and neck using cadaveric specimens. Staining the vessels of the arterial and venous systems of a cadaveric specimen aids the de tailed understanding of the vascularization of anatomical structures of the brain.

Occipital artery to middle cerebral artery bypass in cases of unavailable superficial temporal artery
In neurosurgery, extracranial-to-intracranial (EC-IC) bypass surgery is necessary for patients who have undergone surgery in which the superficial temporal artery (STA) was already used for a different bypass procedure or was damaged. Here, we report our experience with EC-IC bypass using the occipital artery (OA) in cases in which the STA is unavailable, and discuss the technical considerations and pitfalls. Five patients with ischemic-onset moyamoya disease and atherosclerotic disease were included. (Source: World Neurosurgery)

Coloring technique of magnetic resonance angiography for superficial temporal artery to middle cerebral artery bypass surgery
Superficial temporal artery (STA)-middle cerebral artery (MCA) bypass is an established surgical technique for achieving revascularization. It is important to select the proper recipient artery of MCA. 3D-CTA and conventional angiography are useful in the selection process but need contrast agents. The authors designed the coloring MRA technique that needed no agents to visualize the recipient artery. Retrospective evaluation of the efficacy and limitation for selection of the recipient artery and decision of the place and size of the craniotomy were carried out. (Source: World Neurosurgery)

The Role of Neurosurgery in Countries with Limited Facilities: Facts and Challenges
The Lancet Commission on Global Surgery has recently focused the attention on the lack of surgical care worldwide. Like other surgical subspecialties, neurosurgical care needs to be better distributed around the world, with a major attention to the low-middle income countries. Neurosurgical diseases like hydrocephalus, traumatic brain injury and brain tumours have a high impact on families, individual quality of life and cost for the society. Implementation of neurosurgical care in poor settings is not easy. (Source: World Neurosurgery)

Is Psychiatric Depression a Presenting Neurologic Sign of Meningioma? A Critical Review of the Literature with Causative Etiology.
Benign meningiomas constitute 80-90% of all meningiomas, and represent the most common type of central nervous system (CNS) tumor in adults. The vast majority of meningiomas are minimally symptomatic or asymptomatic early in their onset and thereby can often result in delayed diagnosis. Early diagnosis of meningioma is critical as it can maximize treatment options and improve outcomes and survival. While seizures and focal neurological deficits are considered to be the most prevalent symptoms, depression may also be an important and significant sign. (Source: World Neurosurgery)
