Active clinical trials for "Intracranial Aneurysm"

Subarachnoid haemorrhage (SAH) may cause damage to the hypotalamo-pituitary-adrenal axis (HPA) thus disturbing the hormonal response of these structures. The aim of our study is to characterize the function of HPA-axis acutely and over time up to three months in patients with SAH.

The purposes of this study are to identify possible genes that may increase the risk of aneurysm development in the brain, and to determine the effect of environmental factors such as cigarette smoking and high blood pressure on the expression of these genes.

Searching a dysfunction of corticotropic and thyrotropin axis during the acute phase ( ≤48h ) of a subarachnoid hemorrhage secondary to spontaneous rupture of cerebral aneurysm. Impact on the incidence of complications and recovery are evaluated at 1 month. Blood sample are made within 48 hours of the onset of bleeding with assay of total plasma cortisol, plasma ACTH at 8 am and thyroid hormones (T3, free T4 , and TSH). Dynamic test ACTH stimulation (test Synacthene) with renewal of serum cortisol to H + 1 (60min). Evaluation in the first 30 days of the incidence of rebleeding, hydrocephalus, of vasospasm, infection and epilepsy. GOS to 1 month.

International, non-randomized, European , multicenter, observational study to collect data for the treatment of intracranial aneurysms with OPTIMA coils system to further document its safety and efficacy

Perform a prospective cohort study to compare the incidence and severity of headache between non-stent assisted coiling and stent assisted coiling of unruptured intracranial aneurysms.

Rapid ventricular pacing (RVP) is a technique to obtain flow arrest for short periods of time during dissection or rupture of the aneurysm. RVP results in an adequate fall of blood pressure which presents as an on-off phenomenon. It is not clear whether repetitive periods of pacing are harmless for the patient. Silent cardiac and cerebral infarcts may be undetected. The investigator will study the safety of RVP, particularly for the heart and the brain, retrograde by studying troponin levels and magnetic resonance imaging or computed tomography.

The purpose of this study is to assess the safety and efficacy rates of the treatment of small intracranial aneurysms with Stryker Neurovascular's Target® 360 Ultra coils which are a type of platinum coils used to occlude aneurysms.

Goal directed therapy (GDT) is a technique, which employs a non-invasive cardiac output monitoring (NICOM) device to guide management of circulating blood volume and blood pressure during procedures. The purpose of this study is to determine whether the use of goal-directed therapy to optimize blood volume and cardiac output during the procedure can improve the outcome of patients undergoing endovascular treatment of a brain aneurysm.

A global prospective, multi-center, single-arm, post-market clinical follow-up (PMCF) study conducted to assess the performance of the Medina Embolization Device when used in unruptured and ruptured intracranial aneurysms.

This study will evaluate the hypothesis that the administration of intraventricular tPA reduces the rates of cerebral vasospasm and ventriculoperitoneal shunt-dependent hydrocephalus in patients with aneurysmal subarachnoid hemorrhage.
