For some patients with mobility issues, a walking frame (commonly known as a zimmer frame - trademark of Zimmer Holdings), is provided to keep them on their feet and help them remain more ...
Intracranial pressure is a cornerstone in neurosurgical care used in a variety of diseases. However currently, doubts regarding normal intracranial pressure exist. Few studies have investi...
This study examines the short- and long-term-effects of different repeated frames in which an exercise program is offered on behavior (i.e., frequency of exercise) and motivation (i.e., au...
In certain neurosurgical procedures, the use of a stereotaxic frame is required. It is then possible to set a precise target (depending of the type of the surgery) to be reached by the sur...
Atherosclerotic intracranial arterial（ICA） stenosis and intracranial aneurysms are the common causes of ischemic stroke and hemorrhagic stroke, respectively. Investigators aimed to ass...
Frame-based stereotaxy is generally considered the gold standard for brain biopsies while frameless stereotaxy may expedite efficiency of clinical work flow. There are conflicting reports in the liter...
Our objective is to define the clinical, radiological and technical factors that can condition the emergence of post-biopsy symptomatic intracranial hemorrhage. Based on our findings, we suggest recom...
In complex cases of drug-resistant focal epilepsy, the precise localization of the epileptogenic zone requires simultaneous implantation of depth and subdural grid electrodes. This study describes ...
To investigate the association between vascular morphology and the development of intracranial aneurysms (IAs), the morphological changes of intracranial arteries after IA induction were examined usin...
Idiopathic intracranial hypertension (IIH) is a syndrome of unknown cause that is increasing in frequency. Patients who are typically women of childbearing age and obese present with headaches and may...
A well-circumscribed mass composed of tuberculous granulation tissue that may occur in the cerebral hemispheres, cerebellum, brain stem, or perimeningeal spaces. Multiple lesions are quite common. Management of intracranial manifestations vary with lesion site. Intracranial tuberculomas may be associated with SEIZURES, focal neurologic deficits, and INTRACRANIAL HYPERTENSION. Spinal cord tuberculomas may be associated with localized or radicular pain, weakness, sensory loss, and incontinence. Tuberculomas may arise as OPPORTUNISTIC INFECTIONS, but also occur in immunocompetent individuals.
Embolism or thrombosis involving blood vessels which supply intracranial structures. Emboli may originate from extracranial or intracranial sources. Thrombosis may occur in arterial or venous structures.
Abnormal outpouching in the wall of intracranial blood vessels. Most common are the saccular (berry) aneurysms located at branch points in CIRCLE OF WILLIS at the base of the brain. Vessel rupture results in SUBARACHNOID HEMORRHAGE or INTRACRANIAL HEMORRHAGES. Giant aneurysms (>2.5 cm in diameter) may compress adjacent structures, including the OCULOMOTOR NERVE. (From Adams et al., Principles of Neurology, 6th ed, p841)
Increased pressure within the cranial vault. This may result from several conditions, including HYDROCEPHALUS; BRAIN EDEMA; intracranial masses; severe systemic HYPERTENSION; PSEUDOTUMOR CEREBRI; and other disorders.
Bleeding into the SUBARACHNOID SPACE due to CRANIOCEREBRAL TRAUMA. Minor hemorrhages may be asymptomatic; moderate to severe hemorrhages may be associated with INTRACRANIAL HYPERTENSION and VASOSPASM, INTRACRANIAL.
