Abdominal aorta
We measured the volume of the abdominal aorta and the results were shown in Figure 5 . The percentage of AbTL was decreased, the percentage of AbTL in TATL was also decreased, and the percentage of AbFL was increased. In the long FET group, AbTL/AbFL was decreased by 13%, AbTL/AbAL did not change (P =0.6685), AbFL/AbAL was increased by 0.5%, and AbTL/TTL was decreased by 4.5%. In the short FET group, AbTL/AbFL was decreased by 13%, AbTL/AbAL was decreased by 5%, AbFL/AbAL was increased by 5%, and AbTL/TTL was decreased by 6%.
