title: Nonsurgical treatment of scalp arteriovenous malformation using a combination of ultrasound-guided thrombin injection and transarterial coil embolization.
abstract: Scalp arteriovenous malformations are treated by surgical excision in many patients. We report a patient with a scalp arteriovenous malformation who was successfully treated by a combination of ultrasound-guided thrombin injection (UGTI) and transarterial coil embolization. This patient was a 52-year-old man with a subcutaneous mass in the left retroauricular region. An angiogram showed that the mass was a nidus of arteriovenous malformation. We performed UGTI after transarterial coil embolization. No recurrence or complication was reported during 2 years of follow-up. This report describes the advantages of UGTI and the method for complete occlusion of the collateral artery.
