ABSTRACT
The middle cerebral artery occlusion reperfusion (MCAO/R) model is crucial for understanding the pathological mechanisms of stroke and for drug development.However, among the commonly used modeling methods, the Koizumi method often faces scrutiny due to its ligation of the common carotid artery (CCA) and its inability to achieve adequate reperfusion. Similarly, the Longa method has been criticized for disconnecting and ligating the external carotid artery (ECA). This study aims to introduce a modified model preparation method that preserves the integrity of the ECA, involves inserting a monofilament nylon suture through the CCA, repairing the ligated CCA incision, and maintaining reperfusion from the CCA. Reperfusion of blood flow was confirmed using laser speckle flow imaging. Evaluation methods such as the Longa scale, Modified Neurological Severity Score, triphenyltetrazolium chloride (TTC) staining, and immunofluorescence labeling of neurons demonstrated that this approach could induce stable ischemic nerve damage. This modified MCAO/R model protocol is simple and stable, providing valuable guidance for practitioners in the field of cerebral ischemia.
