Insights
Arteriovenous malformations in the rectum and sigmoid colon can cause severe bleeding. Preoperative angioembolization followed by surgical resection effectively managed a pediatric case, reducing bleeding risks.
Area of Science:
- Pediatric Surgery
- Vascular Malformations
- Gastroenterology
Background:
- Arteriovenous malformations (AVMs) are complex vascular anomalies.
- Lower gastrointestinal bleeding in children can be challenging to manage.
- Rectosigmoid AVMs pose a risk of significant hemorrhage.
Abstract:
We present a case of a child with ongoing lower gastrointestinal bleeding caused by a rectosigmoid arteriovenous malformation. To reduce perioperative bleeding, we performed preoperative angioembolization followed by subsequent resection by low anterior resection. Here we present the case and review the literature regarding neoadjuvent embolization for gastrointestinal and pelvic arteriovenous malformations.
