Active clinical trials for "Subarachnoid Hemorrhage"

The purpose of this study is to determine the feasibility of conducting a large trial examining the effect on clinical outcome of a liberal red blood cell (RBC) transfusion strategy compared to a restrictive strategy (usual care) in patients with aneurysmal subarachnoid hemorrhage (SAH).

The primary objective of this project is to investigate the effect of statin therapy on cerebral blood flow in patients with aneurysmal SAH who are randomized to receive or not receive statins in a blinded design.

The purpose of this phase II study is to further assess the safety of tiopronin in aneurysmal subarachnoid hemorrhage(aSAH) patients in order to obtain preliminary data on the efficacy of tiopronin versus placebo in reducing serum and cerebrospinal fluid (CSF) 3AP levels in this patient population.

Brain injury patients who meet defined criteria will be assigned to intensive insulin treatment (target blood glucose levels of 10-110 mg/dl) or conventional IV insulin treatment (target glucose of 150-170 mg/dl). Follow up will occur at 3, 6 and 12 months. The primary outcome measure will be neurological outcome at 12 months according to Karnofsky Performance Scale (KPS). A general view of outcome will also be presented as favorable (good recovery+ moderate disability), unfavorable (severely disabled+ vegetative state), and dead. Secondary outcome measures will be blood glucose levels and death.The investigators will also record systemic complications like pulmonary emboli, pulmonary edema, myocardial infarction, ventricular arrhythmias, and pneumonia.

Recent study has shown that inhalatory sedation is a practicable, effective and not risky method in Intensive Care Unit. Sevoflurane effect on cerebral system have been described in previous studies: it causes an increasing of cerebral blood flow and a decrease of oxygen cerebral consumption. Clinical strategy for Subarachnoid Hemorrhage is orientated to increase cerebral blood flow to limit vasospasm phenomena after SAH. Scope of this study is to evaluate the Cerebral Blood Flow variation associated to Isoflurane sedation versus conventional sedation with propofol .

Despite the advances in neurosurgical and -radiological techniques and intensive care, the mortality and morbidity rates in SAH have not changed in recent years. There is still only a limited understanding of the mechanisms of secondary insults causing brain injury after SAH, also called delayed cerebral ischemia (DCI). In this study, the investigators are exploring the use of quantifiable biomarkers from blood and continuous EEG monitoring as tools for the diagnostics of DCI. Additionally, the investigators are looking into other clinical variables (eg. pain, heart function) as factors of DCI.

HYBRID study is prospective randomized open label controlled multi center trial, to compare Hydrocoil and bare platinum coil for recanalization after endovascular treatment of intracranial aneurysms.

The purpose of this study is to determine the impact of in situ fibrinolysis on the mortality at 30 days in case of subarachnoid hemorrhage.

In this project we are collecting cerebrospinal fluid and blood from patients at Vanderbilt Medical Center who have a subarachnoid hemorrhage which has followed the rupture of a brain aneurysm. We then propose to study the cerebrospinal fluid using a novel microscopic laser directed mass spectrometric analysis (MALDI) available at Vanderbilt. The cerebrospinal fluid and blood will then be analysed for different biological markers, protein expression and gene expression. These markers will then be statistically correlated with clinical data including prediction of vasospasm, time to vasospasm and response to standard therapy.

Cerebral swelling is a major complication following aneurysmal subarachnoid hemorrhage.This study is a retrospective cohort aimed to predict the extent of brain swelling. Cerebral venous assessment can identify the risk of brain swelling and improve surgical outcomes.
