Objective: The aim of this study was to demonstrate the changes of PDA
aneurysm by performing a serial imaging study
Methods: A newborn was found to have a large ductus arteriosus by
screening two-dimentional echocardiography (2DE) on the first day of life.
A ductal aneurysm developed on the third day of life. A series of imaging
studies including 2DE, three-dimentional echocardiography (3DE),
three-dimentional CT (3DCT) and MRI had been performed.
Results: The large ductus arteriosus changed into a ductal aneurysm on the
third day of life and thrombus was gradually formed inside the aneurysm
leaving a small tract with blood flow. The small tract is still patent and
we are still following up the patient.
Conclusions:
3DE and 3DCT enhanced our ability to image and understand the spatial
relationship and changes of the PDA aneurysm anatomy by providing superior
imaging and demonstrating the shape and surrounding structures of the PDA
aneurysm.
