COVID-19 Impact on Intraparenchymal Hemorrhage and Surgical Outcomes: A Comprehensive Analysis.

Aim: To investigate the possible association between COVID-19 infection and intraparenchymal hemorrhage (IPH) by examining changes in the preoperative and postoperative periods, mortality, and the impact of COVID-19 on IPH survival times.

Material And Methods: This cross-sectional retrospective analysis included 82 IPH cases operated on and treated between January 2021 and March 2023. Brain computed tomography/magnetic resonance imaging scans were used to confirm the diagnosis of IPH and provide evidence of neurological damage.

Morphometric analysis of the influence of selenium over vasospastic femoral artery in rats.

Background: Cerebral vasospasm (CV) is the leading cause of morbidity and mortality occurring after subarachnoid hemorrhage (SAH). Etiopathogenesis of CV is multifactorial. Selenium is the cofactor of the glutathione peroxidase (GSH-Px) enzyme which is a very important defense mechanism against antioxidants.
