Overview
Patent ductus arteriosus is classified by the anatomical view of the duct by Krichenko criteria.
Classification
- Krichenko et al. first introduced a method for classifying PDA in 1989.[1]
- 5 types are introduced:
- Type A: conical duct with well defined aortic ampulla and constriction near the pulmonary artery end.
- Type B: large duct with window like structure which is very short in length.
- Type C: tubular duct without any constriction.
- Type D: complex duct with multiple constrictions.
- Type E: elongated duct with constriction remote from the edge of the trachea (as viewed on lateral angiography).
