Carotid versus axillary artery cannulation for descending aorta remodeling in type A acute aortic dissection

Figure 2 Segment changes in the false lumen area ratio in the descending aorta of the axillary artery and carotid artery groups calculated by computed tomography angiography. A: The preoperative (left), postoperative (middle), and postoperative/preoperative (right) false lumen area ratio (FLAR) of the S1; B and C: S2 and S3 segments in the AA and CA groups. S1: Thoracic segment; S2: Upper abdominal segment; S3: Lower abdominal segment. ^aIndicates a significant difference between the two groups (P < 0.01).
