Active clinical trials for "Intracranial Hypotension"

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.

The aim of this study is to assess the efficacy of stent implantation versus medical therapy on idiopathic intracranial hypertension with venous sinus stenosis.

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.

Spontaneous intracranial hypotension (SIH) is an infrequent disease, related to a leak of cerebrospinal fluid. There are not controlled studies for this treatment.The main of this study is to demonstrate the superiority of the Trendelenburg position compared to supine position during 24 hours after an epidural blood patch for a spontaneous intracranial hypotension

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.

The injection of autologous blood Blood Patch (BP) into the epidural space is the standard treatment for headache associated with intracranial hypotension. It provokes cerebral vasoconstriction. It is cons-indicated in a number of situations (HIV positive, fever, sepsis, leukemia). The purpose of this study is to evaluate another technique using a patch made by injecting an epidural hydroxyethylstarch solution (HES 130, 0.4, 6%) instead of blood patch. This alternative technique is simple to implement and does not have some of the specific blood pressure contra-indications. The study aims at comparing the "Blood Patch" group versus the "HES Patch" in terms of clinical efficacy , tolerance, satisfaction of the anesthetist, ease of implementation and effect of the injection of epidural anesthesia on cerebral blood flow within 24 hours.

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.

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.

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.

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.
