Common carotid occlusion treated with endarterectomy followed by superficial temporal artery–middle cerebral artery bypass

Annals of Vascular Surgery - Brief Reports and Innovations, 2023
Surgical treatment of chronic common carotid artery (CCA) occlusion with hemodynamic instability has not been well studied because of the rarity of CCA occlusion and its strategic dilemma due to the difficulty of using ipsilateral superficial temporal ...

Shear Stress Targeted Delivery of Nitroglycerin to Brain Collaterals Improves Ischaemic Stroke Outcome

Advanced Science, EarlyView.
Shear‐activated nanoparticles carrying nitroglycerin selectively target high‐shear stress collateral vessels during ischaemic stroke, enhancing blood flow to at‐risk brain without systemic side effects. This novel approach significantly improves outcomes in animal models, outperforming conventional nitroglycerin delivery.

Granuloma formation and arterial thrombosis following cotton wrapping of an intracranial aneurysm a case report

Arquivos de Neuro-Psiquiatria, 1992
The authors report the case of a patient whose left middle cerebral artery aneurysm was wrapped with cotton. Occlusion of the middle cerebral artery, probably secondary to a foreign-body inflammatory reaction, developed late in the postoperative course ...

Potential use of oxygen as a metabolic biosensor in combination with T2*-weighted MRI to define the ischemic penumbra [PDF]

, 2008
We describe a novel magnetic resonance imaging technique for detecting metabolism indirectly through changes in oxyhemoglobin:deoxyhemoglobin ratios and T2* signal change during ‘oxygen challenge’ (OC, 5 mins 100% O2). During OC, T2* increase reflects O2

Procyanidin B3 and Its Derivatives Alleviate Neuronal Injury by Targeting G3BP1 for Ischemic Stroke Therapy

Advanced Science, EarlyView.
Ischemic stroke is a serious disease with high rates of mortality and disability, but there is a lack of novel therapeutic targets and agents for it. Now it is shown that Ras GTPase‐activating protein SH3 domain‐binding protein 1 (G3BP1) has the potential to serve as a therapeutic target for ischemic stroke.

Occlusion of the Middle Cerebral Artery Branch Mimicking Aneurysm [PDF]

Journal of Korean Neurosurgical Society, 2007
A 26-year-old man was admitted to our department due to intermittent left hemiparesis for 3 months. Magnetic resonance image showed subacute infarction in the right precentral gyrus. Digital subtraction angiography and magnetic resonance angiography revealed an aneurysmal protrusion at the right middle cerebral artery (MCA) bifurcation.

Advances in imaging of new targets for pharmacological intervention in stroke: real-time tracking of T-cells in the ischaemic brain [PDF]

, 2010
Background and purpose: T‐cells may play a role in the evolution of ischaemic damage and repair, but the ability to image these cells in the living brain after a stroke has been limited.

Ultrafine Molybdenum Wire Braided Neurointerventional Implants: Bridging Biodegradability and Neurovascular Safety for Stroke Treatment

Advanced Science, EarlyView.
Molybdenum (Mo), with its unique strength, uniform corrosion, and radiopacity, enables innovative biodegradable implants for transformative stroke therapy. Abstract Neurovascular implants for stroke intervention face a critical dilemma: permanent devices (e.g., nitinol stents, platinum coils) often trigger chronic inflammation and recurrence, whereas ...

Carbon Monoxide Nanomodulator Reverses Ischemia‐Reperfusion Injury in Stroke: A Novel Dual‐Channel Therapy Mode of Co‐driving Neuroprotection and Neurogenesis

Advanced Science, EarlyView.
This work develops a biomimetic and reactive oxygen species‐activated carbon monoxide (CO) nanogenerator to penetrate blood‐brain barrier, arrive in stroke‐affected regions, and release CO in a controlled manner for an innovative dual‐channel therapy strategy via co‐driving neuroprotection and neurogenesis.
