Proteinuria as an independent risk factor for contrast-induced acute kidney injury and mortality in patients with stroke undergoing cerebral angiography

Journal of NeuroInterventional Surgery, 2016
Background The correlation between proteinuria and contrast-induced acute kidney injury (CI-AKI) in patients with cerebrovascular disease is still unknown.

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

Advanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent

Difference in Transcranial Doppler Velocity and Patient Age between Proximal and Distal Middle Cerebral Artery Vasospasms after Aneurysmal Subarachnoid Hemorrhage

Cerebrovascular Diseases Extra, 2016
Background: Transcranial Doppler (TCD) is used to monitor cerebral vasospasm after subarachnoid hemorrhage (SAH), but its diagnostic ability is reported to be limited.

Prevalence of Venous Sinus Stenosis in Spontaneous Cerebrospinal Fluid Leak and the Role for Venous Sinus Stenting: A Systematic Review and Meta‐Analysis

International Forum of Allergy &Rhinology, EarlyView.
ABSTRACT Background Given the association between spontaneous cerebrospinal fluid (sCSF) leak and idiopathic intracranial hypertension (IIH), and the association of IIH and venous sinus stenosis (VSS), we sought to determine the prevalence of VSS in sCSF leak and the role of venous sinus stenting for sCSF leak.

Association of tetralogy of Fallot with multiple variations of the cerebral arteries diagnosed by magnetic resonance angiography

Radiology Case Reports, 2020
Tetralogy of Fallot very rarely manifests with variations of the cerebral arteries, but we detected an extremely rare combination comprising 3 such variants –bilateral carotid–anterior cerebral arteries anastomoses, the vertebral–anterior inferior ...

Compensation pathways for venous drainage of the brain in superior sagittal sinus occlusion by parasagittal meningioma

Medičnì Perspektivi, 2022
This study aims to determine the existing pathways of collateral cerebral circulation in parasagittal meningiomas that cause superior sagittal sinus occlusion based on literature review and analysis of own clinical observations.

Sheep femoral artery occlusion is well tolerated and does not result in ischemia

Animal Models and Experimental Medicine, EarlyView.
Left femoral artery occlusion (yellow arrows) can be seen shortly after the lateral femoral circumflex artery origin, with distal arterial reconstitution. Sheep with femoral artery occlusion showed no change in pain scores nor mobility, thus making them an appropriate model for novel small diameter femoral artery graft studies. Abstract Objective Sheep

Imaging findings and cerebral perfusion in arterial ischemic stroke due to transient cerebral arteriopathy in children [PDF]

Einstein (São Paulo), 2012
We report the case of a 4-year-old female child who developed an arterial ischemic stroke in the left middle cerebral artery territory, due to a proximal stenosis of the supraclinoid internal carotid artery, most probably related to transient cerebral ...
