OBJECTIVE Awake craniotomy is commonly used to resect lesions located near the language area during brain surgery. However, it often difficult perform tasks due several limitations such as difficulty in awakening surgery and intraoperative seizures. This study investigated clinical significance of bidirectional corticocortical evoked potential (CCEP) monitoring a new approach evaluate function. METHODS enrolled 12 patients who underwent awake tumor resection with CCEP assess Electrodes were...
This report describes the use of three fluoroscopy-guided epidural blood patch procedures to treat a patient with spontaneous intracranial hypotension. A 42-year-old woman no history surgery or trauma presented headache and dizziness. Magnetic resonance imaging revealed an extradural cerebrospinal fluid leak collection leading diagnosis Common symptoms hypotension include orthostatic headache, nausea, neck pain, hearing disturbance, dizziness, aural fullness. However, cause in this was not...
The conventional transcranial approach for treating lower basilar artery aneurysms is challenging because the deep and narrow surgical field limits maneuvering clipping. We report a case of 77-year-old female who presented with right hemiparesis caused by partially thrombosed giant aneurysm in her artery. performed neck clipping thrombus debulking using combined endonasal approach. This enabled us to secure parent from side, which difficult achieve alone. It also allowed early removal,...
Although the use of titanium implants in cranioplasty has recently become common, long-term results this strategy are sometimes difficult to manage. The aim study was clarify characteristics patients developing exposure implants. Records eight with were reviewed. Patient ages ranged from 41 77 (mean, 56.8) years. Two male, and six female. periods implantation 5 87 30.5) months. In seven cases, mesh performed after postcraniotomy infections. removed all cases. Scalp tissue closed by applying...
Enlarged perivascular spaces (EPVS) are often observed with magnetic resonance imaging in patients small vessel disease. However, the risk factors, radiological features, and clinical relevance of EPVS moyamoya disease poorly understood. The purpose this study was to evaluate EPVS, factors many pathophysiology adult One hundred cerebral hemispheres 50 were examined. control group consisted age/sex-matched without ischemic numbers at level centrum semiovale per hemisphere compared between...
OBJECTIVE The purpose of this study was to understand the anatomical and functional connections between paracentral lobule (PCL) primary motor cortex (M1) human brain. METHODS This retrospective included 16 patients who underwent resection lesions located near M1. Nine had in dominant hemisphere. Tractography performed visualize connectivity two regions interest (ROIs)—the convexity interhemispheric fissure—that were shown by MRI be activated during a finger tapping task. number, mean...
Rigid endoscopic resection using a thick sheath (ViewSite) may be viable method for the or biopsy of selected deep-seated brain tumors, such as thalamic gliomas and malignant lymphomas. Neuroendoscopic is one technique used histological verification suspected tumors. There are number advantages to this technique. For example, under direct vision, it possible carefully observe tumor surface avoid vessels during resections. It also collect enough specimens pathological diagnosis. Eighteen...
OBJECTIVE Medullary streaks detected on fluid-attenuated inversion recovery (FLAIR) imaging have been considered to be reflected ischemic regions in pediatric moyamoya disease. The purpose of this study was evaluate these medullary both clinically and radiologically discuss associated pathophysiological concerns. METHODS authors retrospectively reviewed data from 14 consecutive patients with disease treated between April 2009 June 2016. Clinical radiological features postoperative changes...
A positive (outward) remodelling pattern in patients with typical atherosclerotic disease was recognised using magnetic resonance imaging (MRI). In this report, the outer diameter of circle Willis evaluated moyamoya disease, and its verified.A total 18 consecutive were included analysis. The terminal portion internal carotid artery (ICA) (C1), proximal middle cerebral (MCA) (M1) anterior (A1) fast employing steady-state acquisition (FIESTA) imaging. estimated these images, compared control...
