Summary
Preoperative embolization significantly reduces blood loss during the resection of giant high-vascular sacrococcygeal teratomas in newborns. This technique enables safer surgical outcomes for infants with these complex tumors.
Area of Science:
- Neonatal surgery
- Vascular malformations
- Pediatric oncology
Background:
- Giant sacrococcygeal teratomas (SCTs) are congenital tumors that can present with high vascularity.
- Surgical resection of highly vascular SCTs in neonates carries a high risk of massive intraoperative hemorrhage, potentially leading to mortality.
- Minimizing blood loss is critical for improving surgical outcomes in neonates undergoing resection of large vascular tumors.
Observation:
- A case of a giant, high-vascular Type-1 sacrococcygeal teratoma was diagnosed in an infant born at 35 weeks gestation.
- The tumor exhibited significant vascularity, posing a substantial risk for exsanguination during surgical resection.
- Endovascular embolization was performed to occlude the feeding arteries supplying the tumor prior to surgical removal.
Findings:
- The endovascular embolization procedure effectively reduced the tumor's vascularity.
- Surgical resection following embolization resulted in minimal blood loss, documented at only 12 ml.
- The infant tolerated the combined treatment approach, achieving a safe surgical outcome.
Implications:
- Preoperative endovascular embolization is a viable and effective strategy for managing high-vascular giant sacrococcygeal teratomas in neonates.
- This approach significantly mitigates the risk of massive bleeding, enhancing surgical safety and improving neonatal outcomes.
- Embolization should be considered as an adjunct to surgical resection for complex, vascular pediatric tumors to reduce perioperative morbidity and mortality.
