Overview

In PERFUSE Grade 6 thrombus, a chronic total occlusion is present.[1]

Characteristics of a chronic total occlusion:

  • The occlusion does not have a "beak like" appearance, and the occlusion has a blunt cut-off/edge
  • Extensive collaterals may be present
  • The clot generally propagates backwards up the proximal vessel to the nearest proximal side branch
