An overview of intracranial aneurysms

McGill Journal of Medicine, 2020
Intracranial aneurysms are relatively common, with a prevalence of approximately 4%. Unruptured aneurysms may cause symptoms mainly due to a mass effect, but the real danger is when an aneurysm ruptures, leading to a subarachnoid hemorrhage.

Analysis of the Role of Vasa Vasorum in the Oxygen Transport to the Aneurysm Wall

International Journal for Numerical Methods in Biomedical Engineering, Volume 41, Issue 6, June 2025.
The observed vasa vasorum network provided adequate oxygen supply to the outer layers of the thickened aneurysm walls, but without the vasa‐vasorum, due to consumption throughout the wall, the oxygen demand could not be met by diffusion from the luminal surface alone. These findings support the idea that local hypoxic conditions in regions of increased

Aneurysmal Subarachnoid Hemorrhage : Posterior Communicating Artery Aneurysms and Long-Term Excess Mortality [PDF]

, 2018
Introduction Aneurysmal subarachnoid hemorrhage (aSAH) is a serious form of stroke, caused by a ruptured intracranial aneurysm. The origin of the posterior communicating artery (PComA) is one of the most common locations for ruptured aneurysms causing ...

Prostaglandin E-2-EP2-NF-kappa B signaling in macrophages as a potential therapeutic target for intracranial aneurysms [PDF]

, 2017
Intracranial aneurysms are common but are generally untreated, and their rupture can lead to subarachnoid hemorrhage. Because of the poor prognosis associated with subarachnoid hemorrhage, preventing the progression of intracranial aneurysms is ...

Prevalence and Risk Factors for Augmented Renal Clearance in Neurocritical Ill Patients

Journal of Clinical Laboratory Analysis, Volume 39, Issue 11, June 2025.
Augmented renal clearance is prevalent in critically neurological patients. Age is likely to significantly influence renal clearance in this population, especially patients with low Scr and cystatin C levels should be given more attention. ABSTRACT Background Augmented renal clearance (ARC) refers to a phenomenon in critically ill patients ...

Application of Magnetic Resonance Imaging in Postoperative Cognitive Dysfunction: A Narrative Review

Organ Medicine, Volume 2, Issue 2, Page 73-89, June 2025.
While POCD diagnosis currently relies on subjective assessments and lacks objectivity, MRI provides an objective means to visualize related brain changes (structural MRI being the current routine standard). Advancing to multiple MRI modalities holds promise for enabling early detection and intervention.
