The collateral circulation is a subsidiary network of vessels that stabilize blood flow when intracranial arterial occlusion or severe stenosis, arterial insufficiency due to thromboembolism, hemodynamic compromise or a combination of these factors may lead to the recruitment of collaterals. Noninvasive imaging techniques now allow for real time assessments of the structural and functional components of this circulation. The adequacy of collaterals at the time of presentation of acute ischemic stroke patients has dramatic implications on the success of endovascular therapy, influencing not only technical success in terms of recanalization rates, but also the ultimate clinical outcome. Collateral status should be included in the process of selecting acute ischemic stroke patients for endovascular therapy, which could help improve our ability to identify those most likely to benefit from treatment.
