Collateral blood vessels in acute ischaemic stroke: a potential therapeutic target

TLDR
Imaging of the brain and vessels has shown that collateral flow can sustain brain tissue for hours after the occlusion of major arteries to the brain, and the augmentation or maintenance of collateral flow is therefore a potential therapeutic target.
Abstract
Summary Ischaemic stroke results from acute arterial occlusion leading to focal hypoperfusion. Thrombolysis is the only proven treatment. Advanced neuroimaging techniques allow a detailed assessment of the cerebral circulation in patients with acute stroke, and provide information about the status of collateral vessels and collateral blood flow, which could attenuate the effects of arterial occlusion. Imaging of the brain and vessels has shown that collateral flow can sustain brain tissue for hours after the occlusion of major arteries to the brain, and the augmentation or maintenance of collateral flow is therefore a potential therapeutic target. Several interventions that might augment collateral blood flow are being investigated.

Relationship between estimated glomerular filtration rate and outcome of ischemic stroke patients after mechanical thrombectomy.

TL;DR: In this paper, the effect of preprocedural renal function on the outcome of acute ischemic stroke patients with mechanical thrombectomy (MT) and whether this effect is modified by the onset-to-reperfusion time (OTR) and mediated by collateral status was investigated.

Mismatch of delayed perfusion volume between TTP and Tmax map of perfusion MRI.

TL;DR: The finding of a large TTP-Tmax perfusion delay mismatch volume in patients with acute stroke who have a PWI-DWI mismatch on an initial MRI may predict that the infarct volume will not increase despite persistent vascular occlusion.

The significance of leptomeningeal collaterals in moyamoya disease

TL;DR: According to the authors, the wide range of complex LMC in the brain of MMD patients should lead to a variety of hemodynamic sources for parasylvian continental arteries (PSCAs) in MMD hemispheres, and results suggested that the recipient vessel in traditional “superficial temporal artery-middle cerebral artery (STA-MCA)” bypass surgery was not always from MCA.

Classification of subtype of acute ischemic stroke. Definitions for use in a multicenter clinical trial. TOAST. Trial of Org 10172 in Acute Stroke Treatment

TL;DR: The TOAST stroke subtype classification system is easy to use and has good interobserver agreement and should allow investigators to report responses to treatment among important subgroups of patients with ischemic stroke.

Thresholds in cerebral ischemia - the ischemic penumbra.

J Astrup, +2 more

TL;DR: Recent evidence indicates that immediate failure of basic functions such as synaptic transmission, ion pumping and energy metabolism in the ischemic brain, is critically dependent on residual blood flow, and that these functions fail at certain critical flow thresholds.
