Subdural hygromas are often found bilaterally in spontaneous intracranial hypotension (SIH). They frequently progress to chronic subdural hematomas (CSDHs), and if the hematomas are formed, it is difficult to consider SIH as an underlying cause. Whether SIH is underlying or not among the patients presenting bilateral subdural fluid collections (hygromas or CSDHs) is clinically important because the treatment strategy should be different between them.

To investigate clinical and imaging features of 40 patients with spontaneous intracranial hypotension (SIH).
One commonly cited complication of neuraxial techniques is postdural puncture headache. Patients with spontaneous intracranial hypotension may present with a similar constellation of symptoms in the a...
Spontaneous intracranial hypotension is a rare condition for which no optimal treatment guidelines have been determined. The most common presentation is orthostatic headaches, but patients can present...
Various signs may be observed on brain magnetic resonance imaging (MRI) in patients with spontaneous intracranial hypotension (SIH). However, the lack of a classification system integrating these find...
Spontaneous intracranial hypotension (SIH) is a syndrome that was unknown until the advent of magnetic resonance imaging (MRI). It is a cause of orthostatic headache, which remains underdiagnosed and,...
The purpose of this study is to estimate the intracranial pressure (ICP, the pressure in your head) in subjects with intracranial hypotension (a condition caused by leakage of the fluid th...
Observational Study of the Differences in Characteristics of the Spontaneous Electroencephalogram, Derived From the Left and Right Hemisphere in Patients With Unilateral Intracranial Tumor During Routine Anesthesia: Comparison With a Control Group Without
Study of the influence of brain tumor on bilateral electroencephalogram (EEG) during anaesthesia.
Hypotension frequently occurs during anesthesia induction. Preload decrease by anesthetics was often considered as one of main causes for this hypotension. However, the studies on this top...
The goal of this randomized controlled trial (RCT) is to compare the efficacy of CT fluoroscopy-guided targeted epidural patching for treatment of imaging-confirmed spinal CSF leaks to tha...
A prospective, single-arm, open-label, multicenter post-approval study to determine whether the use of the Acumen HPI Software to guide intraoperative hemodynamic management in non-cardiac...
Reduction of CEREBROSPINAL FLUID pressure characterized clinically by HEADACHE which is maximal in an upright posture and occasionally by an abducens nerve palsy (see ABDUCENS NERVE DISEASES), neck stiffness, hearing loss (see DEAFNESS); NAUSEA; and other symptoms. This condition may be spontaneous or secondary to SPINAL PUNCTURE; NEUROSURGICAL PROCEDURES; DEHYDRATION; UREMIA; trauma (see also CRANIOCEREBRAL TRAUMA); and other processes. Chronic hypotension may be associated with subdural hematomas (see HEMATOMA, SUBDURAL) or hygromas. (From Semin Neurol 1996 Mar;16(1):5-10; Adams et al., Principles of Neurology, 6th ed, pp637-8)
Bleeding into the intracranial or spinal SUBARACHNOID SPACE, most resulting from INTRACRANIAL ANEURYSM rupture. It can occur after traumatic injuries (SUBARACHNOID HEMORRHAGE, TRAUMATIC). Clinical features include HEADACHE; NAUSEA; VOMITING, nuchal rigidity, variable neurological deficits and reduced mental status.
A sporadic neurodegenerative disease with onset in middle-age characterized clinically by Parkinsonian features (e.g., MUSCLE RIGIDITY; HYPOKINESIA; stooped posture) and HYPOTENSION. This condition is considered a clinical variant of MULTIPLE SYSTEM ATROPHY. Pathologic features include a prominent loss of neurons in the zona compacta of the SUBSTANTIA NIGRA and PUTAMEN. (From Adams et al., Principles of Neurology, 6th ed, p1075-6)
An autosomal disorder of the peripheral and autonomic nervous systems limited to individuals of Ashkenazic Jewish descent. Clinical manifestations are present at birth and include diminished lacrimation, defective thermoregulation, orthostatic hypotension (HYPOTENSION, ORTHOSTATIC), fixed pupils, excessive SWEATING, loss of pain and temperature sensation, and absent reflexes. Pathologic features include reduced numbers of small diameter peripheral nerve fibers and autonomic ganglion neurons.

An acquired or spontaneous abnormality in which there is communication between CAVERNOUS SINUS, a venous structure, and the CAROTID ARTERIES. It is often associated with HEAD TRAUMA, specifically basilar skull fractures (SKULL FRACTURE, BASILAR). Clinical signs often include VISION DISORDERS and INTRACRANIAL HYPERTENSION.
