Two congenital cases

[Bhavin Jankharia]

Hi

These two cases illustrate the use of cardiac CT in extra-cardiac
vessel analysis, whether they are extra-cardiac shunts or aortic or
pulmonary pathologies.

The first is a paient with a bi-directional Glenn shunt, which is
normal and well seen -

The second is a young child with a double aortic arch forming a
vascular ring and causing tracheal compression with fusion images of
the trachea and the ring -

This has been discussed in a case report in a recent issue of AJR -
