To investigate the clinical effect and surgical techniques of fourth ventricle astrocytoma resection through the median suboccipital keyhole approach.
This article was published in the following journal.
Name: World neurosurgery
Arachnoid cysts are common anomalies in the intracranial region. However, an intraventricular arachnoid cyst is rare, and occurrence within the fourth ventricle is especially uncommon; only 16 cases h...
This 3-dimensional operative video covers the suboccipital approach to a brainstem cavernoma of the floor of the fourth ventricle. Brainstem cavernomas are low-flow vascular lesions associated with a ...
This video illustrates the case of a patient with familial cerebral cavernous malformation syndrome with a history of multiple symptomatic hemorrhages attributable to a medullary malformation. The pat...
Ruptured aneurysms causing intraventricular hemorrhage (IVH) are associated with high morbidity. The presence of blood that completely fills the fourth ventricle (cast fourth ventricle, CFV) is though...
This video demonstrates microsurgical resection of low-grade (Grade I) thoracic spinal cord astrocytoma. Astrocytomas are the most common pediatric intramedullary tumors and occur secondary to ependym...
This study seeks to determine the optimum dose frequency of 5-Azacytidin (5-AZA) infusions into the fourth ventricle of the brain. The study's primary objective is to establish the maximum...
Prospective controlled clinical trial in which a minimally invasive microsurgical approach was used following the keyhole principle in 55 patients and 65 hands under local anesthesia and a...
The goal of this clinical research study is to learn if infusions of a particular type of patients' own white blood cells called natural killer (NK) cells can reliably and safely be given ...
Objectives: To evaluate the clinical efficacy of using a manual inhibition technique for the suboccipital muscles compared with the use of the so-called INYBI tool in individuals with chro...
This is a Phase 2 study in subjects with WHO Grade III Anaplastic Astrocytoma (G3 astrocytoma) who had progressive disease during first or second line treatment and who have not previously...
An irregularly shaped cavity in the rhombencephalon, between the medulla oblongata, the pons, and the isthmus in front, and the cerebellum behind. It is continuous with the central canal of the cord below and with the CEREBRAL AQUEDUCT above, and through its lateral and median apertures it communicates with the subarachnoid space.
Primary or metastatic neoplasms of the CEREBELLUM. Tumors in this location frequently present with ATAXIA or signs of INTRACRANIAL HYPERTENSION due to obstruction of the fourth ventricle. Common primary cerebellar tumors include fibrillary ASTROCYTOMA and cerebellar HEMANGIOBLASTOMA. The cerebellum is a relatively common site for tumor metastases from the lung, breast, and other distant organs. (From Okazaki & Scheithauer, Atlas of Neuropathology, 1988, p86 and p141)
Intracranial tumors originating in the region of the brain inferior to the tentorium cerebelli, which contains the cerebellum, fourth ventricle, cerebellopontine angle, brain stem, and related structures. Primary tumors of this region are more frequent in children, and may present with ATAXIA; CRANIAL NERVE DISEASES; vomiting; HEADACHE; HYDROCEPHALUS; or other signs of neurologic dysfunction. Relatively frequent histologic subtypes include TERATOMA; MEDULLOBLASTOMA; GLIOBLASTOMA; ASTROCYTOMA; EPENDYMOMA; CRANIOPHARYNGIOMA; and choroid plexus papilloma (PAPILLOMA, CHOROID PLEXUS).
Four CSF-filled (see CEREBROSPINAL FLUID) cavities within the cerebral hemispheres (LATERAL VENTRICLES), in the midline (THIRD VENTRICLE) and within the PONS and MEDULLA OBLONGATA (FOURTH VENTRICLE).
A narrow cleft inferior to the corpus callosum, within the diencephalon, between the paired thalami. Its floor is formed by the HYPOTHALAMUS, its anterior wall by the lamina terminalis, and its roof by EPENDYMA. It communicates with the FOURTH VENTRICLE by the CEREBRAL AQUEDUCT, and with the LATERAL VENTRICLES by the interventricular foramina.
According to the American Brain Tumor Association, just over 24,000 patients will be diagnosed with a primary malignant brain tumour during 2012 in the US alone. Some 80% of primary malignant brain tumours are gliomas, a broad term which includes all tum...
Surgery is a technology consisting of a physical intervention on tissues. All forms of surgery are considered invasive procedures; so-called "noninvasive surgery" usually refers to an excision that does not penetrate the structure being exci...
