Introduction:
Carotid angioplasty and stenting (CAS) has been demonstrated to be safe and an acceptable alternative to surgery. Stent malpositioning can occur during the maneuvers of delivering; technical errors can lead to proximal or distal slipping of the stent that needs the placement of additional pieces.
Presentation Of Case:
We describe the case of a postoperative dislocation of a carotid stent that happened 1 year after placement. After the first ultrasound control confirmed the correct position of the Stent the following one, executed 9 months later, showed a severe restenosis due to a proximal dislocation of the stent. The problem was solved with the positioning of a further one more distally.
Discussion:
We observe the possibility of Carotid Wallstent shortening during the implant due to an incorrect placement or sizing, but a delayed displacement is a rare complication that, we highlight, can occur after CAS and that needs to be considered at the moment of the preoperative planning.
Conclusion:
After CAS a closed ultrasound follow up is advisable for a long time in order to detect unexpected complications.
