  Figure 1 The CT images. (A and B) The CT angiography (performed 2 months ago) showed no endoleak and no interval change of the aneurysmal sac size (10×16 cm). (C) In this presentation, an increase in aneurysmal sac size (12×16 cm) and contrast leakage (arrow) in front of the left limb of the stent-graft were observed.CT = computed tomography.

  Figure 2 The fluoroscopic and aortographic images. (A) The fluoroscopy showed a diastolic compression of the main body of stent-graft. (B) The aortography showed that the left limb extension (implanted 2 years ago) for type IIIa endoleak was focally bulged at the systolic phase (arrow), which was considered an active-seal phenomenon of the AFX device (Endologix, Inc., Irvine, CA, USA). Another focal bulging at the connection part of the modular components was also observed (arrowhead), indicating a suspicious type IIIa endoleak.

  Figure 3 The completion aortographic and fluoroscopic images. (A) The completion aortography showed that the focal bulging of left limb disappeared after the additional placement of a stent-graft (dashed line), but the pulsatile compression of the main body persisted (arrow). (B) After 7 days, the fluoroscopy revealed that the pulsatile compression of the stent-graft completely disappeared.
