We report two cases demonstrating supravalvular aortic stenosis (a common feature of Williams syndrome) and coarctation of the aorta on computed tomography (CT) aortogram.
CT aortogram with 3D reformats confirmed supravalvular aortic narrowing, coarctation of the aorta just distal to the left subclavian artery (long segment 6 mm) as well as coarctation distally of the descending aorta (Figs 1 a & b, 2 & 3).
Muriel Gordon, a radiology resident at AEMC, obtained the patient's written consent to undergo an aortogram
scheduled to be performed by Dr.
Subsequently, an aortogram
was obtained, and it confirmed the presence of several anomalous, large-caliber vessels branching off the aorta (Figure 2, arrows).
showed two tears in the thoracic aorta.
An abdominal aortogram
showed a 50% narrowing of the ostium of the right renal artery, complete occlusion of the proximal portion of the left common iliac artery with bridging collaterals, 75% narrowing of the proximal right common iliac artery by a complex plaque, and 70% narrowing at the ostium of the right internal iliac artery.
revealed brisk extravasations from the CHA origin (Fig.
These included 138 aortic arch/four-vessel ar teriograms, 116 aortograms
with distal run-off, and 6 renal arteriograms.
In 1981, Strife et al (3) reviewed approximately 172 anteroposterior aortograms
and angiocardiograms and 1,000 lateral radiographs from infants, children, and adolescents.
In addition, many centers also perform peripheral vascular angiography ranging from diagnostic aortograms
to peripheral vascular angioplasty and stent placement.
Cardiac catheterization and aortograms
were done which did not show any issues with the repair.
It has a cardiac portion, a pulmonary angiography portion, it has an abdomen CT portion, and we use it for our CT vascular studies, CT angiograms and aortograms
, as well.
