Notably, recanalization of the occluded artery also reestablished the glymphatic flow. Focal brain ischemia occurs when a blood clot has occluded a cerebral vessel. The cuff is inflated until the artery is completely occluded. These patients require immediate reperfusion (re-opening) of the occluded vessel. The above algorithm does not account for images containing an object that is partially occluded. This variably present structure would be important if either vessel were occluded. Occluded fronts usually form around mature low pressure areas. Occluded fronts usually form around mature low-pressure areas. Occluded fronts have an area of warm air aloft. Occasionally, cyclogenesis will re-occur with occluded cyclones. The sun is often occluded during the monsoon season. More showers were centered near the occluded low. It has however been demonstrated that pigeons do not complete occluded shapes. At the advanced stage of ankylosis, joint mobility is completely occluded.
