To report two rare cases of late stent dislodgement occurring nearly seven years after implantation in pediatric patients, highlighting the need for ongoing monitoring.
Key Findings:
Both cases exhibited very late dislodgement of aortic isthmus stents after stable long-term implantation, raising concerns about stent stability.
Stent migration is a rare complication typically occurring in the peri-procedural or early post-implantation period, necessitating careful follow-up.
Somatic growth, structural stent changes, and balloon dilations contributed to stent dislodgement, indicating the need for individualized monitoring strategies.
Interpretation:
The findings challenge the assumption that endovascular stents are permanently incorporated into the vessel wall shortly after implantation, suggesting a need for ongoing assessment of stent behavior.
Limitations:
The cases are limited to two patients, which may not represent the broader population, and further studies are needed to validate these findings.
Long-term behavior of stents may vary based on individual anatomical and procedural factors, highlighting the need for personalized follow-up.
Conclusion:
Late stent dislodgement is exceptional and underscores the need for careful consideration of stent behavior in pediatric patients during follow-up procedures, emphasizing the importance of ongoing monitoring.
