Overview
In TIMI Grade 6 thrombus, a chronic total occlusion is present.[1]
The characteristics of a chronic total occlusion are:
- 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.
Example
Shown below are an animated image an a static image depicting TIMI grade 6 thrombus in the left circumflex. Encircled in yellow in the image on the right is the thrombus, where you can notice an abrupt blunt cut-off appearance. Outlined in yellow in the same image on the right is the path of the dye in a collateral artery arising from the LAD.
Shown below are two animated images of the same case depicting TIMI grade 6 thrombus in the left circumflex. The image on the left shows the same thrombus before PCI and the image on the left shows the patent left circumflex after PCI.
