Dynamic cardiac computed tomography
Dynamic cardiac computed tomography (CT) was performed preoperatively in
our series for two patients. In patient P4, intracranial arteriovenous
malformations were strongly suspected of leading to dilatation of the
SVC. Dynamic cardiac CT revealed a moderately large ASD (superior sinus
venosus type; Figures5to 8). The right superior pulmonary vein drained into the terminal
portion of the SVC. This scenario was suggestive of both PAPVC and
PAPVD. The main, right, and left pulmonary arteries were dilated, which
was suggestive of pulmonary arterial hypertension. The left vertebral
artery arose directly from the aortic arch as a third branch. The
proximal, middle, and distal diameters of the SVC each measured
approximately 8.7 mm.
