Summary: The pathophysiological mechanisms of aneurysmal subarachnoid haemorrhage (aSAH) involve early brain injury (EBI) and delayed cerebral ischemia (DCI). Several mechanisms contribute to EBI pathogenesis, including cell death, inflammatory response, oxidative stress, excitotoxicity, microcirculatory dysfunction, microthrombosis and cortical spreading depolarization. All are suggested to be linked due ...

Summary: The study is an observational prospective evaluation of an approved and unchanged clinical management, evaluating different diagnosis methods to assess brain perfusion in patients with an aneurysmal or AVM-related intracranial hemorrhage

Summary: Patients with subarachnoid hemorrhage are prone to suffer from dysnatriemia. Evidence shows that hyponatriemia is associated with increased incidence of vasospasm, brain swelling and mortality in these patients. Patients with subarachnoid hemorrhage often require large amounts of iv fluids in order to maintain euvolemia and support cardiocirculatory function. Prior evidence shows that the type of ...

Summary: Ruptured cerebral aneurysms lead to subarachnoid hemorrhage (SAH),that has a high morbidity and mortality rate, the severity of which is predicted by the Hunt-Hess grade (HHG). SAH leads to iron (Fe) and hemoglobin (Hb) accumulation in the brain, which is toxic for neurons. Ferritin (iron reported in the brian) and iron overload leads to brain atrophy, specifically in the mesial temporal lobe (hip...

Summary: The Stroke Recovery Initiative is a nation-wide participant recruitment registry that connects people who have had a stroke with researchers who are working to develop new approaches to improve recovery after stroke.

Summary: Intracranial aneurysm is the main cause of subarachnoid hemorrhage, and the incidence of subarachnoid hemorrhage in Chinese population is about 5%. The intervention of unruptured intracranial aneurysms is controversial because of its great harm after natural rupture and bleeding, and about a quarter of patients still have poor prognosis through existing invasive treatment methods. How to accuratel...

Summary: This is a monocentric randomized prospective trial comparing 2 different endovascular strategies of intracranial arterial angioplasty in case of refractory intracranial arterial vasospastic stenosis : chemical angioplasty chemical and mechanical angioplasty

Summary: The aim of this study is to evaluate the effect of inhalational sedation on cerebral perfusion in patients with SAH. It will evaluate whether the administration of isofluorane, by inducing direct vasodilation in the cerebral parenchyma, can improve the cerebral perfusion rates. Perfusional CT will be used to study the variation of cerebral blood flow to rule out the vasodilatory effect on territor...

Summary: A double-blinded placebo-controlled randomized trial to evaluate the effect of preventative treatment of depression in survivors of aneurysmal subarachnoid hemorrhage (aSAH), a type of stroke.

Summary: Subarachnoid hemorrhage (SAH) is a frequent and severe disease. Mortality can reach 40%. The most frequent complication of SAH is arterial vasospasm, with estimated incidence as high as 70%. Vasospasm is responsible for cerebral ischemia leading to severe morbidity, poorer quality of life and increased mortality. Intravenous Milrinone, because of vasodilatory properties could be a therapeutic opti...

Background: While the intensive care of patients with life-threatening brain illnesses has advanced tremendously, a large number of therapies are still without proper scientific support. This can be partly explained by the fact that mechanisms of initial brain injury are still not well understood. Why additional neurological injury occurs during a patient's stay in the NeuroCritical Care Unit (NCCU) despite c...

Summary: Aneurysmal subarachnoid hemorrhage (SAH) is a fatal disease with high morbidity and mortality. While the primary injury results from the initial bleeding and cannot be influenced, secondary injury through vasospasms and delayed cerebral ischemia (DCI) during the course of the disease might be a target for intervention in order to improve outcome. To date, beside the aneurysm treatment to prevent r...
