Active clinical trials for "Intracranial Aneurysm"

To investigate whether stellate ganglion block is helpful to brain protection during cranial aneurysm surgery

Endovascular treatment is now the first line treatment for the management of intracranial aneurysms. However aneurysm recanalization is an important limitation to this treatment. Several factors seems to be associated with aneurysm recanalization including medical history of the patient, aneurysm status (ruptured or unruptured), aneurysm size and location, modalities of treatment, immediate post-operative occlusion of the aneurysm. A precise knowledge of factors increasing the risk of aneurysm recanalization is quite important to optimize strategy of treatment and reduce the recanalization rate. No large, prospective, multicenter trial dealing with this question has been published in the literature.

The primary objective of this study is to demonstrate effectiveness and safety of the NeuroForm Atlas stent system for use in patients requiring stent assisted intracranial aneurysm treatment.

Endovascular treatment of ruptured and unruptured intracranial aneurysms presents complications, mainly the thrombo-embolic complication. No specific studies have been conducted to study factors associated with the occurrence of thromboembolic complications (symptomatic or not) post endovascular treatment of intracranial aneurysms.

A prospective, multicenter, observational assessment of the safety and effectiveness of the LVIS® device in the treatment of wide necked intracranial aneurysms.

A prospective, multicenter, observational evaluation of the safety and efficacy of the FRED® device in the treatment of intracranial aneurysms

Intracranial aneurysm (localized dilatation in weakened blood vessel wall) rupture is a catastrophic disease, with half of the victims died and many of the survivors disabled. There is currently no data in the literature for the Chinese population concerning the prevalence, characteristics (location and size) and risk of harboring an unruptured intracranial aneurysm. In this study, the investigators aim to study the population prevalence and characteristics (location and size) of intracranial aneurysm in Hong Kong Chinese, and its cost-effectiveness. The screening is carried out using magnetic resonance angiography (MRA), with a 3-T magnetic resonance system, which is a well-established non-invasive method for intracranial aneurysm detection.

The purpose of this study is to evaluate the morbidity, mortality, and efficacy of use of the Enterprise(TM) stent for the treatment of (ruptured or non-ruptured) intracranial aneurysms.

This is a prospective observational multicenter registry to evaluate safety and efficacy data on Neuroform3TM stenting for treatment with endovascular coiling of wide neck aneurysms on an intent to treat basis. The objectives of this study are: Assessment of morbidity-mortality at 1 month and 12-18 months following the treatment of the intracranial aneurysm with Neuroform3TM stent and endovascular coiling using the modified Rankin scale (mRS). to evaluate adverse events. Angiographic assessment at 12-18 months compared to the initial post-treatment assessment via the modified Raymond scale and same/better/worse scale.

Purpose: Phase 1: (Pilot Phase) To compare the treatment efficacy of surgical clipping and endovascular coiling for unruptured intracranial aneurysms. To obtain better estimates of morbidity and mortality related to a surgical or endovascular treatment strategy at one year within the context of an RCT. To show that an RCT comparing the morbidity and mortality of a surgical management strategy to an endovascular management strategy is feasible. Phase 2: To compare the results of surgical and endovascular management strategies, in terms of: Overall mortality and morbidity at 1 and 5 years. The clinical efficacy and safety of a surgical or endovascular management strategy at 1 and 5 years Hypotheses: Phase 1 Hypotheses: Surgical clipping of intradural, saccular, unruptured intracranial aneurysms is superior to endovascular management in terms of a lesser number of patients experiencing treatment failure. An RCT comparing the clinical outcomes of a surgical versus endovascular management strategy is feasible. Phase 1 Primary End-points: • Treatment failure, hereby defined as having occurred when either: the intended initial modality (surgical or endovascular) fails to occlude the aneurysm, a "major" (saccular) angiographic aneurysm recurrence is found, or an intracranial hemorrhagic event occurs during the 1-year follow-up period. Phase 1 Secondary End-points: Overall morbidity and mortality at one year. Occurrence of morbidity (mRS >2) or mortality following treatment. Occurrence of failure of aneurysm occlusion using the initial intended treatment modality. Occurrence of a "major" (saccular) angiographic aneurysm recurrence. Occurrence of an intracranial hemorrhage following treatment. Peri-treatment hospitalization lasting more than 5 days Discharge following treatment to a location other than home Treatment: Trial feasibility, or the capacity for patient recruitment, would require enrollment of at least 8 patients per actively recruiting center per year. Phase 2 Hypotheses: It may be too early to explicitly define the primary hypothesis of Phase 2, however, the intent of Phase 2 can be expressed as: One management strategy is superior to the other in terms of clinical outcome at five years. One management strategy is superior to the other in terms of clinical efficacy at five years.
