Patent ductus arteriosus chest x ray
Introduction
Overview
Overview
The findings on chest x ray depends on the degree of shunting between left and right system.
Chest X Ray
Chest X Ray
Small-Sized PDA
- Normal heart size and vascularity.[1]
Medium-Sized PDA
- Occasionally, the ductus can be seen as a separate convexity between the aortic knob and the pulmonary artery segments.[2]
- Cardiomegaly related to left atrium and left ventricular volume overloads.
- Increase in the pulmonary vascular markings.
- The ascending aorta may be prominent due to increased flow.
Large-Sized PDA
- Similar to a PDA complicated by pulmonary vascular disease.[3][4]
- Left ventricular overload regresses by adolescence and the heart size may revert to normal.
- The apex may be tilted upward reflecting right ventricular hypertrophy.
- The pulmonary trunk and its branches are markedly dilated and may show central calcification, but in the outer third there is an abrupt decrease in vascularity.
