Filter by:SIH is a debilitating neurological disorder caused by a cerebrospinal fluid leak, with an estimated incidence of 5 per 100,000 persons per year, of which mostly women between the ages of 35 years and 55 years (1). The typical presentation is moderate-to-severe orthostatic headache and several other possible neurological symptoms, that significantly impact patients' quality of life (2). Treatment of SIH usually starts with conservative measures, consisting of strict supine bed rest, hydration, caffeine, and simple analgesics (3). The vast majority of patients will require invasive treatments for their CSF leak, such as epidural blood patches, fibrin glue patches, endovascular coiling, and/or surgical repair (4). These specialized treatments are only offered in tertiary care centers and require specialized personnel and resources, which implicates a certain waiting time for the patients before permanent treatment is offered (5). In the meantime, due to the lack of an effective and accessible alternative, patients continue to suffer. The GONB has been reported as a simple, safe, and effective treatment to provide short-to-intermediate term relief of migraine (6), cervicogenic headache, cluster headache (7), occipital neuralgia, and more recently, post-dural puncture headaches (PDPH) (8). As the pathophysiology of intracranial hypotension caused by SIH or PDPH is very similar (9), it is stipulated that the effect of GONB will be similar for SIH patients. However, to date, no studies exploring the efficacy of GONB for SIH have been performed. We propose to do a prospective observational study to explore the outcome of GONB for SIH. GONB can serve as a bridge therapy to control the debilitating headache of SIH while patients are awaiting permanent SIH treatment. Moreover, GONB can be performed by physicians of different specialties including neurology, which makes it an accessible treatment for all patients. Lastly, by offering better symptom control, this intervention could potentially restore patients' ability to work and reduce healthcare costs.
The purpose of this research is to determine the efficacy of paraspinal vein embolization for treatment of digital subtraction myelography (DSM) or CT myelography (CTM) confirmed cerebrospinal fluid (CSF)-venous fistulas so that researchers can inform the development and design of future clinical trials of this technique.
The aim of this study is to assess the efficacy of stent implantation versus medical therapy on idiopathic intracranial hypertension with venous sinus stenosis.
Administration of intravascular fluids is one of the methods to prevent SA-induced hypotension, but empirical intraoperative volume repletion carries the risk of fluid overload during elective surgery. Over fluid resuscitation is associated with organ dysfunction and higher mortality rate , thus, to avoid ineffective or even harmful intravascular volume expansion, it is important to have tools to predict hypotension and fluid responsiveness.
The proportion of the elderly population is increasing rapidly. Chronic subdural hematoma has become the most common cause of surgery in neurosurgery for elderly patients. The standard treatment for cSDH is mostly surgery. Clinically, we often encounter elderly patients with certain underlying diseases or organ dysfunction, especially preexisting cardiovascular disease or medication history like anticoagulant or antiplatelet drugs, resulting in poor surgical tolerance, high risk during anesthesia and hematoma recurrence. At present, the mechanism of cSDH is not completely clear. Our previous observational studies had shown significant correlation between cSDH and intracranial hypotension. So we would like to conduct a randomized, controlled, multi-center clinical study to explore the effectiveness and safety of low intracranial pressure treatment strategies for patients with chronic subdural hematoma.
This is observational study. The investigator will measure optic nerve sheath diameter by ultrasound on the eye after cesarean section under spinal anesthesia.
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 that of a simulated procedure without patching material in patients with spontaneous intracranial hypotension.
Hypertonic saline is used to treat elevated intracranial pressure. Intraosseous vascular access has been used to administer fluids and medications. This study combines these to administer 3% hypertonic saline via IO.
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 that surrounds your brain and spine) using non-invasive magnetic resonance imaging (MRI) techniques, and to determine whether changes in estimated ICP are seen after treatment of this condition.
Previous research has identified spontaneous cerebral spinal fluid leakage as a cause for spontaneous intracranial hypotension, leading to positional headache patterns. Typical magnetic resonance imaging findings include subdural fluid collections, enhancement of pachymenginges, engorgement of venous structures, pituitary hyperemia, and sagging of the brain (SEEPS). Because pituitary hyperemia has been documented in cases of spontaneous cerebral spinal fluid leakage and is known to mimic a pituitary tumor or hyperplasia, the investigators would like to like to assess the clinical manifestations and neuroimaging abnormalities of SIH patients with regard to the pituitary gland. Specifically, the investigators are looking to analyze the compression of the pituitary stalk and conduct a systemic evaluation of pituitary function in SIH patients.
