Gamma knife radiosurgery (GKRS) is recognized as an important treatment modality for meningioma.To analyze the long-term outcomes in meningioma patients treated with GKRS to determine risk factors related failure and peritumoral edema (PTE) development.Between 1998 2010, 770 consecutive were intracranial meningioma. After exclusion of follow-up periods less than 5 yr those neurofibromatosis, multiple meningiomas, nonbenign meningioma, or radiotherapy, a total 424 enrolled this study. The...
A total of 130 patients with metastatic brain tumors were treated the Gamma Knife; 85 had multiple lesions. The marginal dose was 14–30 Gy for initial 20 cases during first 6 months. Thereafter, we increased to between 25 and 30 last 110 cases. follow-up period ranged from 1 49 months (mean 9 months). recurrence rate fell 20% early low-dose 4.6% later higher-dose (p = 0.043). Transient neurological deterioration developed in 7 (5.4%), permanent deficits recognized a further (4.6%)....
ABSTRACT Stress affects the serotonergic system, which is associated with depression. Previous research has showed that chronic stress causes deactivation of limbic system. However, influence acute physical on system in vivo was primarily unclear. The purpose this to elucidate effects using PET. For quantification 5‐HT 1A receptors brain, we measured [ 18 F]Mefway uptake two experiment groups (control and despair rats). group subjected external stressful situation (i.e., forced swimming)...
Abstract Cerebrospinal fluid (CSF) leakage after endoscopic skull base surgery remains a challenge despite multilayer reconstruction including nasoseptal flap (NSF) has become standard technique. Injectable hydroxyapatite (HXA) shown promising results to prevent CSF leakage. This study aimed validate the efficacy of HXA-based performed by less-experienced neurosurgeons who had short-term clinical experiences as independent surgeons. Between March 2018 and November 2022, 41 patients...
Objective : Chronic subdural hematoma (CSDH) is a common disease in neurosurgical departments, but optimal perioperative management guidelines have not yet been established. We aimed to assess the current clinical and outcomes for CSDH patients identify prognostic factors recurrence.Methods enrolled total of 293 consecutive with who underwent burr hole craniostomy at seven institutions 2018. Clinical surgery-related characteristics surgical were analyzed. The cohort included 208 men 85...
<b><i>Background:</i></b> Gamma knife radiosurgery (GKRS) has recently been used as a treatment modality for dural arteriovenous fistula (DAVF). <b><i>Objective:</i></b> To retrospectively analyze the outcomes of GKRS DAVF at single institute. <b><i>Methods:</i></b> Between 1998 and 2016, total 20 patients underwent DAVF. After excluding 4 with &#x3e; 12 months follow-up, 16 were enrolled in this study. Twelve had...
Nonfunctioning pituitary adenoma is a primary benign brain neoplasm and the transsphenoidal approach known for safe effective first-line surgical treatment tumours. The aim of this study was to retrospectively analyse outcomes nonfunctioning adenomas treated at single institute.A total 181 patients who underwent with institute from March 1998 November 2018 were included in study. Ninety-six (53.0%) men 85 (47.0%) women aged 21-79 years included. median outpatient follow-up duration 58...
Epidermoid cysts are uncommon intracranial tumors. As one of the extradural types epidermoid cysts, intradiploic even rarer tumors and occur in any part skull. We herein report a rare case giant cyst occipital bone. A 57-year-old woman presented with 1-year history localized headache area. CT MRI showed an mass measuring 50×70 mm bone bony destruction. The patient underwent surgical resection. tumor was completely removed its capsule. There no extension to intradural space. pathological...
The aim of the present study is to retrospectively analyze surgical outcomes and complications microscopic endoscopic transsphenoidal surgery in management Rathke cleft cysts (RCCs) at a single institution. A total 38 patients were enrolled this study. All diagnosed with RCCs, which confirmed histopathologically. Endocrine function, radiological, clinical evaluated following surgery. This cohort consisted 16 male 22 female patients. median age was 48 years (range, 21–72). follow-up duration...
Objective: The evolution of microsurgical techniques enables neurosurgeons to treat various lesions through limited keyhole approaches. supraorbital craniotomy via an eyebrow incision is a less invasive approach for accessing anterior skull base lesions. This has been used access number pathologies including tumors and vascular abnormalities. Surgeons can in the subfrontal, suprasellar, Sylvian fissure, posterior fossa regions. We report our experience with this minimally technique...
Migration is one of the major complications after inserting a self-expandable metal stent (SEMS) into colon [1] [2] [3]. We report case migrated SEMS from ascending that had been impacted wall transverse colon.
Multiple brain abscesses associated with the lung mass require differential diagnosis from cancerous diseases. Here, we report a rare case of multiple originating abscess. A 65-year-old man presented 2-day history motor weakness during antibiotic treatment for pneumonia. Brain magnetic resonance imaging (MRI) revealed enhanced lesions various sizes in whole brain. Diffusion-weighted MRI showed high signal intensity several lesions, and (MR) spectroscopy reduced N-acetyl-aspartate (NAA)...
