Figure 1 Measurement of the Total Aortic Diameter and False Lumen Area
(A) The maximal short-axial diameter of the aorta was measured (black line). (B) The computed tomography imaging system software measured the maximal false lumen area. The false lumen area is delineated by the red line.

Figure 2 Influence of MFLA on Incidence of In-Hospital Complications
Differences in incidence of total in-hospital complications, rupture, progression, and end-organ malperfusion between patients with maximal false lumen area (MFLA)  922 mm2
(green bars) and those with MFLA <922 mm2
(yellow bars). *p = 0.01, **p < 0.01, and ***p < 0.001 compared with patients with MFLA <922 mm2.

Figure 3 Influence of BVI Number on Incidence of In-Hospital Complications
Differences in incidence of total in-hospital complications, progression, and end-organ malperfusion between patients with branch-vessel involvement (BVI) number 2 (green bars) and those with BVI number <2 (yellow bars). *p = 0.01 and **p < 0.001 between patients with BVI number 2 and <2.
