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.
