¿Por qué los portales subcutáneos se quedan atorados?
Topic overview
Case-control study examining risk factors for difficult subcutaneous port removal in pediatric patients. Acute lymphoblastic leukemia diagnosis and prolonged placement duration (median 2.6 vs 0.8 years) were significantly associated with stuck ports requiring complex removal techniques.
Key takeaways
- Polyurethane ports placed for ALL treatment (2+ years) have significantly higher risk of becoming stuck during removal.
- 86% of stuck ports occurred in ALL patients vs 22% in controls; median placement duration 2.6 vs 0.8 years.
- Subclavian access and polyurethane catheters (vs silicone) are associated with difficult port removals in children.
- Preoperative planning for long-term ALL ports should include endovascular backup and extended OR time allocation.
- Catheter surface roughness at removal correlates with difficulty (92.6% stuck ports vs 9.4% controls).
