Stroke Model (MCAO)

The middle cerebral artery occlusion (MCAO) model is a commonly used technique for the creation of a stroke model. Laser Doppler is typically used in order to confirm that occlusion has taken place and ischaemia has occurred. With successful surgery novel therapies can be tested to assess the impact on stroke recovery. Typical published figures demonstrate that a reduction in monitored blood flow of up to 90% can be observed following successful occlusion.

Produktempfehlungen

We recommend the moorVMS-LDF, moorVMS-PC software, VP10M200ST master probe with P10d single fibre slave probe with corresponding probe holders. Surgical glue and accelerator can be used to securely fix the probes in place. For thicker skulls (older/ larger rodents) the single fibre solution may not penetrate the skull sufficiently and in this case the twin fibre VP14-CBF probe is used. For those using a stereotaxic frame we recommend the use of needle probes, the VP3, VP4 or VP5.
