    Two cases of late stent dislodgement in pediatric aortic isthmus occurred nearly seven years post-implantation during follow-up procedures.

  • 2

    Both cases demonstrated that long-term stent behavior in the pediatric aorta may be heterogeneous, challenging assumptions of permanent fixation.

  • 3

    In Case 1, stent mobility during catheter manipulation suggested minimal long-term fixation, while Case 2 involved dislodgement due to stent fracture.

  • 4

    Procedural triggers for dislodgement included extensive catheter manipulation and advancement of a stiff long sheath, highlighting risks during reintervention.

    These cases suggest that pre-dilation of existing stents may improve wall apposition, while covered stents may be preferable in the presence of aneurysms.
