Use of Brain Oxygen Tension Level and Cleaved-tau Protein to Detect Vasospasm After SAH

Subarachnoid HemorrhageCerebral Vasospasm

The purpose of this study is to investigate if brain oxygen levels, levels of a specific protein in the cerebrospinal fluid and blood (Cleaved-tau protein), and brain blood flow can predict spasm of brain blood vessels after bleeding in the brain from a ruptured aneurysm.

Cerebral Vasospasm After Subarachnoid Hemorrhage

Cerebral vasospasm(CVS) after subarachnoid hemorrhage (SAH) results in a considerable amount of transient or even permanent neurological deficits and poor outcome of the patients. Transluminal Balloon angioplasty (TBA) or intraarterial application of vasodilators represents a rescue therapy for severe CVS. Indication, duration and efficacy of this treatment, however, is still under debate. Aim of the study is to investigate if such a rescue treatment can significantly reduce new delayed ischemic cerebral deficits after SAH. Hypothesis is that the occurance of delayed infarcts can be reduced by repetetive intraarterial therapy to more than 50 %.

Lumenate Observational Vasospasm Interventional Trial (LOVIT)

VasospasmIntracranial1 more

The LOVIT study is a European prospective, multi-center, open-label, single-arm feasibility trial designed to determine the safety and angiographic effectiveness through 30 days post treatment with Lumenate Intraluminal Device in the treatment of symptomatic vasospasm.

Sildenafil for Prevention of Cerebral Vasospasm

Subarachnoid HemorrhageCerebral Vasospasm1 more

A Randomized Clinical Trial with security and dose testing of Sildenafil Citrate in patients with subarachnoid hemorrhage due to a rupture of a cerebral aneurism for prevention of cerebral vasospasm. The cerebral vasospasm is a decrease in blood flow that occurs when the intracranial vessels lose their capability of self-control of dilations and contractions. Patients with subarachnoid hemorrhage without neurological deficits who underwent endovascular or surgical correction of the aneurysm can participate in this trial. They will be randomized to a daily doses of 75 mg of Sildenafil, 150 mg of Sildenafil or Placebo from the third to the 14th day post bleeding. Today there is no proven clinical treatment for prevention of cerebral vasospasm.

Safety Study of Sildenafil in Treatment of Cerebral Aneurysm Vasospasm

Cerebral VasospasmSubarachnoid Hemorrhage

Rupture of a cerebral aneurysm is a serious medical condition that may result in permanent disability or even death just related to the aneurysm rupture itself. Patients who undergo successful surgical treatment of their aneurysm will rarely experience problems related to that specific aneurysm in the future. However, blood that is on the surface of the brain from the initial aneurysm rupture is very irritating to other blood vessels that it comes in contact with. When these blood vessels become irritated, they spasm and become narrower. This narrowing restricts blood flow through the vessel, and if severe can result in a stroke that is caused by inadequate blood flow through the vessel. Depending on location and severity, this condition of vessel spasm (cerebral vasospasm) may result in permanent disability or death. Treatment to prevent cerebral vasospasm decreases the risk of stroke. This research is trying to see if a medication that is FDA approved for the treatment of lung disease and sexual dysfunction can be used to prevent and/or treat cerebral vasospasm.

Contrast Enhanced Ultrasound Imaging for Cerebral Perfusion Measurement in Cerebral Vasospasm After...

Subarachnoid Hemorrhage

The objective of the study is to assess brain tissue perfusion by ultrasound perfusion imaging. Specifically to diagnose brain tissue hypoperfusion due to CVS with contrast enhanced UPI and to assess specificity and sensitivity, and predictive values for detection of brain tissue hypoperfusion leading to infarction to test whether treatment-effects by induced hypertension, balloon-dilatation, or intra-arterial nimodipine infusion can be detected and quantified by UPI

Acetazolamide Challenge With Perfusion in the Prediction of Cerebral Vasospasm

Subarachnoid HemorrhageAneurysmal2 more

The investigators propose a technique using cone beam CT perfusion (CBCTP) imaging with an acetazolamide challenge as a potential diagnostic tool to detect a defect in cerebral autoregulation at a time when it has not yet caused clinically apparent signs or symptoms. 30 participants will be enrolled at the University of Wisconsin - Madison and can expect to be on study for about 2 weeks.

Brain Aneurysms: Utility of Cisternal Urokinase Irrigation

Subarachnoid HemorrhageAneurysmal3 more

Despite the efforts made in its treatment, aneurysmal subarachnoid haemorrhage continues to induce high mortality and morbidity rates. Today there are treatment protocols in all hospitals. The vast majority prefer, whenever possible, the endovascular route, given its lesser aggressiveness and morbidity. Although embolization prevents aneurysm' rebleeding, it does remove the subarachnoid blood clot. Therefore, it does not modify the evolution, incidence and severity of vasospasm. The idea is to carry out a 10-year retrospective study classifying patients into five groups based on the type of treatment received, analyzing the results' differences. The aim is to improve what is done as much as possible and to be able to propose potential areas for improvement. Besides, this study will be the basis of a future prospective study, prepared without the current one's biases and errors.
