The relationship between high density (HD) on computed tomographic (CT) scans (which indicates a collection of blood in the subarachnoid space) and cerebral vasospasm was studied in 177 patients with ruptured aneurysm. The development of cerebral vasospasm was confirmed at the high rate of 84.6% in 26 cases where HD was demonstrated on the CT scan within 4 days after subarachnoid hemorrhage (SAH). In 8 cases where HD was not found on the CT scan obtained within 4 days after SAH, no cerebral vasospasm was seen. However, no relationship was found between HD and the occurrence of cerebral vasospasm in cases in which CT was performed after the 5th day of disease. It is suggested that CT performed within 4 days after SAH may give important information for predicting cerebral vasospasm.

: Subarachnoid hemorrhage is a serious condition caused by ruptured intracranial aneurysms, resulting in severe disability mainly in young adults. Cerebral vasospasm is one of the most common complication of subarachnoid hemorrhage; thus, active prevention is key to improve the prognosis. The glycosylation of proteins is a critical quality attribute which is reportedly altered in patients diagnosed with acute ischemic stroke.

Objective: Inflammation contributes to morbidity following subarachnoid hemorrhage (SAH). The authors of this study evaluate how applying noninvasive transauricular vagus nerve stimulation (taVNS) can target this deleterious inflammatory response following SAH and reduce the rate of radiographic vasospasm.
Methods: In this prospective, triple-blinded, randomized controlled trial, 27 patients were randomized to taVNS or sham stimulation.
The clinical impact of recent amphetamine exposure in aneurysmal subarachnoid hemorrhage patients.

Background: Amphetamines possess sympathomimetic properties that can affect cerebral vasculature though conflicting reports exist about their effect on vasospasm risk and clinical outcomes in aneurysmal subarachnoid hemorrhage. This study aimed to characterize the impact of recent amphetamine use on vasospasm development in aneurysmal subarachnoid hemorrhage as well as neurological outcomes.
Methods: We retrospectively screened 441 consecutive patients admitted with a diagnosis of subarachnoid hemorrhage who underwent at least one cerebral digital subtraction angiogram.
Thrombolysis for aneurysmal subarachnoid haemorrhage.

Background: Aneurysmal subarachnoid haemorrhage continues to cause a significant burden of morbidity and mortality despite advances in care. Trials investigating local administration of thrombolytics have reported promising results.
Objectives: - To assess the effect of thrombolysis on improving functional outcome and case fatality following aneurysmal subarachnoid haemorrhage - To determine the effect of thrombolysis on the risk of cerebral artery vasospasm, delayed cerebral ischaemia, and hydrocephalus following subarachnoid haemorrhage - To determine the risk of complications of local thrombolysis in aneurysmal subarachnoid haemorrhage SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (last searched 9 March 2023), MEDLINE Ovid (1946 to 9 March 2023), and Embase Ovid (1974 to 9 March 2023).
