Patient Data

Age: 50
Gender: Male

Aorta CT


Ascendant aorta aneurysm >50 mm.
Patent ductus arteriosus, elongated type, with contrast media blushing into the midly dilated pulmonary arterial trunk (left to right shunt).
Dilated left atrium with septal interlobular thickening and peribronchovascular thickening, most likely from mild cardiogenic edema.

Case Discussion

Given that size of aortic aneurysm is >50 mm, treatment is advocated.
In this case, there is no associated cardiac malformation.

Patent ductus may lead to pulmonary hypertension.
Treatment can be endovascular closure or surgical ligation.
