Implication
Clinical study demonstrates that angiographic collateral grade dictates recanalization success in acute ischemic stroke, indicating that collateral assessment should guide endovascular therapy.
Key Points
- Determine whether angiographic collateral circulation grade predicts vessel recanalization and clinical outcomes following endovascular revascularization in acute ischemic stroke.
- Evaluated angiographic collateral grade in patients undergoing endovascular revascularization therapy for acute cerebral ischemia.
- Assessed post-procedural recanalization rates and clinical recovery in relation to baseline collateral status.
- Angiographic collateral grade directly determined successful vessel recanalization rates following endovascular intervention.
- Successful therapeutic revascularization failed to produce clinical benefit in patients who presented with poor baseline collateral flow.
