Encephalic hemodynamic phases in subarachnoid hemorrhage: how to improve the protective effect in patient prognoses
نویسندگان
چکیده
Subarachnoid hemorrhage is frequently associated with poor prognoses. Three different hemodynamic phases were identified during subarachnoid hemorrhage: oligemia, hyperemia, and vasospasm. Each phase is associated with brain metabolic changes. In this review, we correlated the hemodynamic phases with brain metabolism and potential treatment options in the hopes of improving patient prognoses.

Received: 8 Oct, 2008 Accepted: 11 Feb, 2009 Abstract Arteriovenous Malformation( AVM ) is one of the most common etiologies of subarachnoid hemorrhage. In the past, conventional angiography was the only way for the diagnosis of AVM but nowadays, using noninvasive devices such as MRA and recently TCD, the diagnosis of AVM is revaluated. This patient is a 19 year old man who was admitte...

Cerebral vasospasm considered to be a serious cause of morbidity and mortality following subarachnoid haemorrhage (SAH).Despite several available therapeutic options, current protocols do not prevent major consequences of vasospasm. Inflammation is believed to play an important role in post-haemorrhagic vasospasm. Meloxicam is a non-steroidal anti-inflammatory drug. The aim of this study was to...

متن کاملCardiac Complication Following Subarachnoid Hemorrhage
Besides its severe neurological injuries, spontaneous subarachnoid hemorrhage (SAH) commonly causes cardiac complications. These complications could include three different aspects of cardiac diseases, that is, electrocardiographic abnormalities, myocardial injuries, and left ventricular dysfunction. These complications not only may lead to misdiagnosis of SAH as myocardial infarction, but also...

BACKGROUND AND PURPOSE The efficacy of intra-arterial administration of nimodipine (IAN) in patients with severe vasospasm after aneurysmal subarachnoid hemorrhage (SAH) remains unproved. The goal of the present study was to investigate the clinical effect and cerebral perfusion after IAN in patients with severe vasospasm refractory to hemodynamic treatment. MATERIALS AND METHODS Twenty-six o...
