The intraluminal monofilament model of middle cerebral artery occlusion (MCAO) involves the insertion of a surgical filament into the external carotid artery and threading it forward into the internal carotid artery (ICA) until the tip occludes the origin of the MCA, resulting in a cessation of blood flow and subsequent brain infarction in the ...

MCAO是middle cerebral artery occlusion 的缩写形式，中文意思为中脑动脉栓塞。 大脑中动脉栓塞模型并不是把线栓插进大脑中动脉，而是经颈内动脉入颅并插入大脑前动脉，从而阻塞来自栓塞侧的大脑前动脉的血供，以及堵塞接受后交通动脉血供的的颈内动脉颅内段。

2011年2月13日 · The intraluminal monofilament model of middle cerebral artery occlusion (MCAO) involves the insertion of a surgical filament into the external carotid artery and threading it forward into the internal carotid artery (ICA) until the tip occludes the origin of the MCA, resulting in a cessation of blood flow and subsequent brain infarction in the ...

Here, we describe a detailed methodology on how to develop MCAO stroke in rodents using intra-arterial insertion of filament to occlude the middle cerebral artery. This approach allows for the study of a wide array of basic pathophysiology mechanisms, regenerative medicine and rehabilitation therapy.

Middle cerebral artery occlusion (MCAO) with 1-hour ischemia followed by reperfusion is a widely used stroke model in rodents that has significant limitations such as high mortality and severe neurological deficit hampering comprehensive neurobehavioral evaluation.

2011年2月13日 · 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.

2023年6月23日 · Ischemic stroke in rodents is usually induced by intraluminal middle cerebral artery occlusion (MCAO) via the common carotid artery plugging filament invented by Koizumi et al. (MCAO-KM), or the...

6 天之前 · The distance was approximately 9.5 to 10.5 mm from the tip of the monofilament to the common carotid artery bifurcation. After 1 h of MCAO, the monofilament was retracted to allow reperfusion. The Sham-operated mice underwent the same surgical procedures as the experimental mice except that the monofilament was not inserted.

2022年7月6日 · Middle cerebral artery occlusion (MCAO) induced brain ischemia-reperfusion model in Mice is essential for understanding the pathology of stroke and investigating potential treatments, in which a variety of methods may be employed to block the middle cerebral artery (MCA), the most common being through the insertion of a monofilament; however ...

2011年5月8日 · This video will be demonstrating the two major approaches for performing intraluminal MCAO procedure in mice in a stepwise fashion, as well as providing insights for potential drawbacks and pitfalls. The ischemic brain tissue will subsequently be stained by 2,3,5-triphenyltetrazolium chloride (TTC) to evaluate the extent of cerebral infarction.
