| Initial scan results may also reveal a hyperdense middle cerebral artery thought to be caused by a fresh clot or embolus. |
| An embolus set free in the circulation might eventually be trapped in a narrower vessel and lead to a serious lesion in the neighbouring parts. |
| The embolus is carried in the blood stream until it gets stuck in a place where it forms a blockage. |
| Air should not be used to inflate balloons, the balloon rupture during use could cause an air embolus. |
| If the embolus reaches a blood vessel it cannot flow through, a blockage occurs. |
| Pulmonary embolus is an important risk factor for mortality in these patients. |
