Conclusions—Our preliminary results indicate that RhoA expression and activity in peripheral blood mononuclear cells might be related with aSAH severity and cerebral vasospasm. RhoA is a potential biomarker of the risks associated with aSAH.
Conclusion: Intraocular hemorrhage has previously been described in association with intracranial hemorrhage and in particular subarachnoid hemorrhage (Terson syndrome). We describe a similar clinical picture in the context of cerebral venous sinus thrombosis with no associated intracranial hemorrhage.
AbstractPurpose of ReviewCerebral autoregulation (CA) is a mechanism that maintains cerebral blood flow constant despite fluctuations in systemic arterial blood pressure. This review will focus on recent studies that measured CA non-invasively in acute cerebrovascular events, a feature unique to the transcranial Doppler ultrasound. We will summarize the rationale for CA assessment in acute cerebrovascular disorders and specifically evaluate the existing data on the value of CA measures in relation to clinical severity, guiding management decisions, and prognostication.Recent FindingsExisting data suggest that CA is general...
Conclusions Patients who are older and suffer from poor psychological outcomes are at an increased risk of failing to RTW 1-year post-aSAH. Our interactive results give us information about which patients should be streamlined for therapy to target their psychosocial needs.

Mitchell Stroke is a leading cause of death and disability, and while preferences for cardiopulmonary resuscitation (CPR) are frequently discussed, there is limited evidence detailing outcomes after CPR among acute cerebrovascular neurology (inclusive of stroke, subarachnoid hemorrhage (SAH)) patients. Systematic review and meta-analysis of PubMed and Cochrane libraries from January 1990 to December 2016 was conducted among stroke patients und...
Discussion The paramedian artery of Percheron is a rare anatomic variant and subarachnoid hemorrhage due to aneurysm of this artery is exceedingly rare. This case underlines the importance of a correct evaluation of cerebral arterial anatomy in order to choose the best endovascular therapeutic approach, reduce complications, and optimize patient outcome.

CONCLUSIONS: LncRNA MEG3 is up-regulated in SAH, which may promote SAH-induced neuronal cell injury via inhibition of the Pi3k/Akt pathway. PMID: 29771435 [PubMed - in process]
In anterosuperior-projecting anterior communicating artery (ACoA) aneurysms, the aneurysm dome usually adheres to one or both proximal A2 segment, which may present technical difficulties. This video demonstrates microsurgical clipping of a ruptured anterosuperior-projecting AComA aneurysm. A 52-year-old male presented with a Hunt-Hess grade II subarachnoid hemorrhage (SAH). Computed tomography showed SAH in the basal cisterns, sylvian and interhemispheric fissures. Angiography demonstrated a wide-necked AComA aneurysm projecting anterosuperiorly.
We report the successful treatment of the aneurysm with coil embolization.
Conclusion Time ratios at higher risk of DCI had a positive relationship with the CPP thresholds. Keeping CPP above 70 mmHg may be helpful to prevent DCI after aSAH, but it still needs further investigation.
