Insights
This study details a novel technique for percutaneous stent fragment removal in an infant. A two-sided stretching method successfully retrieved a fractured aortic stent fragment without complications.
Area of Science:
- Cardiovascular Medicine
- Pediatric Cardiology
- Interventional Cardiology
Background:
- Fractured stents during cardiac catheterization pose a significant challenge, especially in pediatric patients.
- Retrieval of small, distal stent fragments can be technically demanding, requiring innovative approaches.
Observation:
- A 9-month-old infant experienced stent fracture during cardiac catheterization, leaving a small distal fragment in the aorta.
- A novel two-sided stretching technique was employed, utilizing access from both the carotid and femoral arteries.
Findings:
- The innovative stretching maneuver successfully elongated the fractured stent fragment into a linear shape.
- The modified fragment was safely removed through a 6 Fr sheath without any procedural complications.
Implications:
- This technique offers a potential solution for managing fractured stent fragments in infants and small children.
- Percutaneous removal of challenging stent fragments can be achieved with specialized, minimally invasive methods.
Abstract:
We present the case of percutaneous removal of a fractured stent fragment during cardiac catheterisation using a novel stretching method. The procedure was performed in a 9-month-old infant. The small distal fragment of a fractured stent in the aorta was stretched using a two-sided approach - that is, from the carotid and femoral artery. This manoeuvre allowed for the removal of the stretched, linear-shaped stent part through a 6 Fr sheath without any local and general complications.
