Figure 2 Receiver-Operating Characteristics Curves
Receiver-operating characteristics curves of the initial false lumen diameter and aorta diameter at the upper (A) and mid descending thoracic aorta (B) for predicting late aneurysmal change in patients with distal aortic dissection. The number on the curve represents the cutoff value of the point. CI = confidence interval.

Figure 3 Three Representative Examples of Long-Term Outcomes
Two patients with a small initial false lumen diameter at the upper descending thoracic aorta showed a complete resorption of the false lumen (left) or did not show an aneurysm for approximately 3 years (middle), while another patient with a large initial false lumen diameter developed an aorta aneurysm after approximately 2.5 years (right).

Figure 4 Rates of Aorta Dilation
Rates of dilation at the upper and mid descending thoracic aorta in patients with large and small initial false lumen diameters at the upper descending thoracic aorta. Each line connects the initial aorta diameter with the final follow-up aorta diameter for each patient. The 2 groups differed significantly in terms of dilating rates at both the upper and mid descending thoracic aorta.
