Overview
In PERFUSE Grade 5 thrombus, a recent total occlusion is present. [1]
The characteristics of a recent total occlusion are:
- There is often a beak like appearance of the occlusion. Chronic occlusions tend to have a more abrupt or straight appearance.
- The clot has not propagated backward to the most distal branch.
- Some collaterals may be present, but usually there are not extensive collaterals.
