Intracranial⁃intracranial bypass for the treatment of complex intracranial aneurysms: technical advances and surgical experience

Chinese Journal of Contemporary Neurology and Neurosurgery
Intracranial-intracranial bypass is a crucial treatment for complex intracranial aneurysms, as it not only achieves aneurysm eradication but also ensures perfusion to the bypassed vascular territory.

Poiseuille Flow of a Non-Local Non-Newtonian Fluid with Wall Slip: A First Step in Modeling Cerebral Microaneurysms [PDF]

Fractal and Fractional Vol. 2, No. 1, 9 (2018), 2018
Cerebral aneurysms and microaneurysms are abnormal vascular dilatations with high risk of rupture. An aneurysmal rupture could cause permanent disability and even death. Finding and treating aneurysms before their rupture is very difficult since symptoms can be easily attributed mistakenly to other common brain diseases.

Accuracy of Length of Virtual Stents in Treatment of Intracranial Wide-Necked Aneurysms. [PDF]

, 2019
Background and purposePrecise stent deployment is important for successful treatment of intracranial aneurysms by stent-assisted coiling (SAC). We evaluated the accuracy of virtual stents generated using commercial stent planning software by comparing ...

Genetics of Intracranial Aneurysms [PDF]

Stroke, 2018
Intracranial aneurysms (IAs) are localized dilatations of intracranial arteries that are because of weaknesses of the endothelial layer. These dilations vary in size (small aneurysms, 25 mm) and are classified according to their shapes: either localized sac-like pouches or long dilatations that increase the vessels diameter; these shapes are referred ...

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

Journal of Clinical Laboratory Analysis, EarlyView.
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 ...

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. Most aneurysms are asymptomatic and will not rupture, but they grow unpredictably and even small aneurysms carry

LncRNA PVT1 Facilitates Phenotypic Switching of Vascular Smooth Muscle Cells in Intracranial Aneurysms by Recruiting KDM1A to Reduce H3K9me2 Modification

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This study explores the differential expression of lncRNA PVT1 in intracranial aneurysms (IAs) and its role in the phenotypic switching of vascular smooth muscle cells (VSMCs). PVT1 and ALOX5 expressions in the serum of IA patients and healthy controls were detected by qRT‐PCR.
