Background: Accurate outcome prediction among patients with aneurysmal subarachnoid haemorrhage (aSAH) has remained elusive. We aimed to identify predictors and develop a model guide clinicians the families of who are being considered for microsurgical repair ruptured aneurysm. Methods: identified 246 consecutive aSAH underwent clipping culprit aneurysm between 01/09/2011 20/07/2020. Independen...

General microvascular perfusion and its heterogeneity are pathophysiological features of delayed cerebral ischemia (DCI) that gaining increasing attention. Recently, CT (CTP) imaging has made it possible to evaluate them radiologically using mean transit time (MTT) (measured by cvMTT). This study evaluates the effect multimodal rescue therapy (intra-arterial nimodipine administration elevation ...

Background. The ideal management of SAH patients with negative initial DSA findings remains unresolved. Objective. (i) To present risk factors, clinical courses, and outcomes in different types of SAH patients with negative DSA findings; (ii) to explore the differences of basal vein between aSAH patients and NASAH patients; and (iii) to evaluate the value of repeated DSA for these patients. Met...

Aneurysmal subarachnoid hemorrhage (SAH) affects 5-10 per 100,000 individuals per year1 and is associated with high rates of morbidity and mortality [1-4]. Main contributor to poor outcomes after SAH are the early cerebral injury (ECI) caused by the immediate increase in intracranial pressure, decreased cerebral perfusion pressure and global ischemia [1,5-9] and delayed cerebral ischemia (DCI) ...

OBJECTIVE Shunt-dependent chronic hydrocephalus (SDCH) is known to be a major complication associated with aneurysmal subarachnoid hemorrhage (aSAH). Old age is known to be one of numerous factors related to the development of SDCH. This study investigated whether postoperative cisternal drainage affects the incidence of SDCH and clinical outcome in elderly patients with aSAH. METHODS Fifty-n...

Cerebral vasospasm (CVS) is a potentially lethal complication of aneurysmal subarachnoid hemorrhage (aSAH). Recently, the symptomatic presentation of CVS has been termed delayed cerebral ischemia (DCI), occurring as early as 3-4 days after the sentinel bleed. For the past 5-6 decades, scientific research has promulgated the theory that cerebral vasospasm plays a primary role in the pathology of...

Aneurysmal subarachnoid hemorrhage- (aSAH-) associated vasospasm constitutes a clinicopathological entity, in which reversible vasculopathy, impaired autoregulatory function, and hypovolemia take place, and lead to the reduction of cerebral perfusion and finally ischemia. Cerebral vasospasm begins most often on the third day after the ictal event and reaches the maximum on the 5th-7th postictal...
