Table 1 Patterns of ICG fluorescence
Pattern | Intensity | Texture | Intestinal mucosa | Outcome |
|---|---|---|---|---|
Hyperemic | Increased | Uniform, smooth | Normal | Viable |
Normal | Normal | Uniform, smooth | Normal | Viable |
Fine granular | Normal to slightly decreased | Fine granular | Erosion | Viable |
Patchy | Decreased | Patches of non-fluorescence ≥ 5 mm diameter | Ulcer | Nonviable or Viable |
Perivascular | Decreased | Only perivascular areas stained | Necrosis/Deep ulcer | Nonviable > Viable |
Nonfluorescent | None | None | Necrosis | Nonviable |
