The atrium is the most common location for masses in the lateral ventricle. However, access to this area is limited owing to its deep location and adjacent eloquent neurovascular structures, such as the choroidal arteries, perisylvian white matter (WM) tracts, and optic radiations. We investigated the feasibility and safety of an endoscopic approach to the atrium via the anterior middle temporal gyrus (MTG). ⋯ Our findings have confirmed the feasibility of an anterior endoscopic approach to the atrium through the anterior MTG, with preservation of the functional integrity of the eloquent cortex and WM tracts.

Cerebral revascularization is used in the treatment of treat complex aneurysms and acute and chronic cerebral occlusive disease. While STA-MCA remains the workhorse of extracranial-intracranial bypass, several approaches for the same have been developed during the past half century. ⋯ While technically challenging and unfamiliar, maxillary-intracranial bypass offers the advantages of higher flow, good caliber matching, shorter graft length, calvarial protection of the interposition graft, and versatility for revascularizing multiple intracranial targets, including the intracranial internal carotid, proximal and middle cerebral, posterior cerebral, and superior cerebellar arteries. We discuss and review the evolution of, operative approaches for, and clinical applications of maxillary artery to intracranial bypass.

Preoperative embolization (POE) of meningioma has been established to facilitate surgical resection, which may reduce intraoperative blood loss and surgical time. However, no consensus has been achieved in meningioma treatment and no meta-analysis has been conducted. The purpose of this study was to perform a systematic review and meta-analysis and provide evidence of the efficacy of meningioma treatment with POE and direct surgery. ⋯ This meta-analysis supports the hypothesis that POE of meningioma is a useful adjunct in meningioma treatment. This technique helps reduce blood loss and surgical time during meningioma resection.

The impact of antithrombotic agents on patients with primary intracerebral hemorrhage (ICH) remains controversial, especially patients who require emergent craniotomy. This study was undertaken to evaluate clinical outcomes in operated patients with ICH with and without previous antithrombotic agents. ⋯ These findings suggested an increased risk of in-hospital mortality and poor short-term outcome among operated patients with ICH with previous antithrombotic therapy, particularly anticoagulant therapy, but not with antiplatelet therapy.

Spontaneous resorption of herniated lumbar disk was explained in the literature by different mechanisms, and multiple predictive factors for resorption were reported in numerous studies. The purpose of this study was to evaluate the phenomena of spontaneous resorption of herniated lumbar disk without surgery (mechanisms, predictive factors, expected time for resorption, and proper time for conservative treatment). ⋯ Spontaneous resorption of herniated lumbar disk can occur by different mechanisms (retraction, dehydration, and inflammatory mediated mechanism). Large and/or sequestrated disks are essential predictive factors for rapid spontaneous resorption. Furthermore, early clinical recovery is usually associated with quick resorption of the herniated disk.
