Figure 1. Computed tomography image of ascending aorta. Peri-graft effusion is shown by the white arrow. As a marker of peri-graft effusion volume, the maximum dimension of peri-graft effusion (E) and the ratio of the peri-graft effusion dimension to graft diameter (E/G ratio) were evaluated as reported previously [16]. (A) Before initiation of the first glucocorticoid treatment (6 weeks after the first surgery): Peri-graft fluid collection. E 10 mm, E/G ratio 0.37. (B) After the first glucocorticoid treatment: Substantial improvement of peri-graft fluid collection. E 2 mm, E/G ratio 0.07. (C) Before initiating the second round of glucocorticoid treatment (6 months after the first surgery): Exacerbation of peri-graft fluid collection. E 14 mm, E/G ratio 0.52. (D) Four months after starting the second glucocorticoid treatment: No recurrence of peri-graft fluid collection. E 2 mm, E/G ratio 0.07.
