Javed Anees: Cerebral Collateral Circulation in Acute Ischemic Stroke
Javed Anees, Medical Consultant at Government of Kerala, shared a post on LinkedIn:
”Cerebral Collateral Circulation in Acute Ischemic Stroke: Part 1
A visual synthesis of anatomy, collateral physiology, multimodal imaging, collateral grading, and evidence-based reperfusion strategies.
Understanding collateral circulation has transformed acute ischemic stroke management—from rigid time windows to tissue-based decision making.
High-quality collateral assessment refines patient selection for intravenous thrombolysis and mechanical thrombectomy, predicts infarct evolution, and helps identify patients who may still benefit from reperfusion despite delayed presentation or large ischemic cores.
This educational infographic integrates current concepts in collateral anatomy, CT/CTA, CT perfusion, MRI, DSA, collateral scoring systems, HIR, ghost-core phenomenon, fetal PCA variants, and practical imaging algorithms into a single postgraduate learning resource.
Designed for educational purposes to support residents, neurologists, neuroradiologists, emergency physicians, and stroke teams.”
