Applying cinematic rendering, it was shown that there were extensive collateralization and dilation of the abdominal wall vasculature including the superior epigastric artery, the inferior epigastric artery and the superficial artery forming an intricate arterial mesh in the middle third of the abdominal wall (Figure 1).

The superior epigastric arteries are also seen originating from severely dilated internal mammary arteries (Figure 2). Findings showed that there was about 50% short segment narrowing of the distal part of the aortic arch (Figure 2) and severe narrowing of the thoracic aorta beginning from the distal part of the aortic arch (diameter 0.9 cm) covering a length of about 10 cm, with significant tortuosity of the descending aorta (Figure 2). Multiple dilated anterior and posterior chest wall vessels were seen (Figure 2).

Also, extensive arterial wall calcifications were seen in the maximum intensity projection images (Figure 3).
