Overview
Buerger's disease may be classified according to the type and size of corkscrew collaterals present into 4 subtypes: type I, artery diameter >2 mm, large helical sign; type II, diameter >1.5 mm and ≤2 mm, medium helical sign; type III, diameter ≥1 mm and ≤1.5 mm, small helical sign; and type IV, diameter <1 mm, tiny helical sign.
Classification
- Buerger's disease may be classified according to the type and size of corkscrew collaterals present into 4 subtypes:[1]
- These subtypes indicate severity of disease and include:
- Type I, artery diameter >2 mm, large helical sign
- Type II, diameter >1.5 mm and ≤2 mm, medium helical sign
- Type III, diameter ≥1 mm and ≤1.5 mm, small helical sign
- Type IV, diameter <1 mm, tiny helical sign
