Abstract

Arteriovenous malformations (AVMs) are rare congenital anomalies characterized by direct communication between arteries and veins that bypass the capillary bed. AVMs may not manifest clinically until late infancy or childhood. In particular, facial AVMs can cause urgent life-threatening dental events. A 5-year-old girl without a medical history visited the hospital because of spontaneous gingival bleeding around the posterior gingival area of the lower left 2nd primary molar. Angiography through the femoral approach under general anesthesia was performed for differential diagnosis and therapeutic option. The blood flow was effectively reduced after arterial embolization alone, and there was no evidence of recurrence at the 5-month follow-up. The present study reports that embolization of the affected vessels can be a more effective and safe method than surgical resection for the treatment of AVM during the growth period.

동정맥 기형(Arteriovenous malformations, AVMs)은 동맥과 정맥이 직접적으로 연결되어 모세혈관과 연결되지 않은 희귀한 선천성 기형 중 하나이다. AVM은 유아기 후반이나 소아기까지는 임상적으로 나타나지 않을 수 있다. 특히 안면 AVM은 생명을 위협하는 치과적 응급 상황을 일으킬 수 있다. 전신병력이 없는 만 5세 여아가 하악 좌측 제2유구치의 후방 치은 주위의 자발적인 잇몸 출혈로 내원하였다. 감별진단 및 치료를 위해 전신마취 하에 대퇴정맥 접근을 통한 혈관조영술이 시행되었다. 동맥색전술 만으로도 혈류량이 효과적으로 감소되었다. 5개월 동안의 경과관찰에서 재발되지 않았다. 본 연구는 성장기 환자에서 이환된 혈관의 색전술이 외과적 절제술보다 더 효과적이고 안전한 방법이 될 수 있다고 보고하는 바이다.
