Here we present a protocol to produce permanent distal middle cerebral artery occlusion in elderly female rats with simultaneous occlusion of the carotid arteries to generate large cortical infarcts and sustained deficits. We show confirmation of the lesion size using structural MRI at 24 hr and 8 weeks after stroke.

Various murine models of middle cerebral artery occlusion (MCAO) are widely used in experimental brain research. Here, we demonstrate the model of transcranial permanent distal MCAO which produces consistent cortical infarction of a size corresponding to damage imposed by the majority of human ischemic strokes.

We demonstrate in the video a method for producing a middle cerebral artery occlusion in adult mice using an intraluminal monofilament. We also show how to evaluate the extent of cerebral infarction by 2,3,5-triphenyltetrazolium chloride (TTC) staining.

We describe a highly reproducible method for the permanent occlusion of a rodent major cerebral blood vessel. This technique can be accomplished with very little peripheral damage, minimal blood loss, a high rate of long-term survival, and consistent infarct volume commensurate with the human clinical population.

The objective of this study was to establish a reproducible method for performing a craniectomy followed by permanent, selective middle cerebral artery occlusion in rats for application in experimental studies of motor and spatial memory deficits.
FAQs
The affected branch determines which brain region receives insufficient blood flow, so clinical findings can differ substantially between patients. Involvement of one territory may affect language, while another may produce sensory or motor changes. The involved hemisphere also matters, making the neurological pattern useful for relating symptoms to the vascular abnormality.
The vascular blockage can produce a central infarct while leaving surrounding tissue potentially salvageable. This distinction matters because the visible or established injury may not represent the entire region at risk. Identifying the occlusion and assessing the clinical situation therefore supports decisions about whether treatments intended to restore blood flow should be considered.
Both thrombus and embolus can obstruct a distal MCA branch and interrupt oxygen delivery to its territory. Their presence provides a possible explanation for the vascular blockage, but the clinical consequences still depend on the branch and hemisphere involved. Combining the suspected obstruction with neurological findings and vascular imaging helps characterize the event.
New deficits involving language, sensation, or movement should prompt consideration of an MCA territory problem, particularly when the findings fit a focal pattern. The precise presentation varies with the affected branch and hemisphere, so clinicians use the examination to localize the likely brain region and determine whether vascular imaging is warranted.
Evaluation combines a neurological assessment with vascular imaging rather than relying on symptoms alone. The examination identifies deficits such as language, sensory, or motor impairment, while CT angiography or MR angiography can demonstrate the affected vessel. Together, these findings help clinicians identify the occlusion, relate it to the presentation, and guide treatment decisions.
Thrombolysis and endovascular thrombectomy are treatment options considered after clinicians identify the occlusion and evaluate the patient’s neurological findings and imaging. The purpose is to address the interrupted blood flow and limit injury when appropriate. Studying these decisions also supports better patient selection and improves understanding of expected outcomes after the event.
