To explore the safety and clinical effects of interventional embolization for iatrogenic post-traumatic arteriovenous fistula (AVF) in children.

Three children with iatrogenic post-traumatic arteriovenous fistula had been confirmed by ultrasound and CTA, and all of them were treated with interventional embolization. All therapy was by the injection of coils or ethanol through. The clinical symptoms and sign changes of all patients were followed-up from 6 months to 2 years.

Arteriography could clearly demonstrate the blood flow of fistula and vein. In 3 patients, no major complications such as ectopic coil embolization tissue necrosis, peripheral nerve palsy or cardio-pulmonary collapse were found. After interventional embolization therapy for 3 times, the clinical symptoms were under control. In the follow up of 6 months to 2 years, 3 cases were clinically cured, l patient was still with pelvic varices, but no significant progress, and there was no abnormality in daily activities in 3 cases.

Interventional embolization for iatrogenic post-traumatic AVF is a safe and effective therapeutic method for AVF in children and is worthy of clinical application.
