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:[2]
- Type A: Conical duct with well defined aortic ampulla and narrowest portion near the pulmonary artery end.
- Type B: Large duct with window like structure which is very short in length at the aortic insertion.
- Type C: Tubular duct without any constriction.
- Type D: Complex duct with multiple constrictions.
- Type E: Elongated duct with multiple conical constriction remote from the edge of the trachea (as viewed on lateral angiography).
