摘要：

下颌骨动静脉畸形被视为一种血管来源的真性肿瘤[1]。由于其发生率低，部位隐蔽。早期常无症状，易误诊和漏诊，常因意外造成不可控制的大出血。早期临床表现易误诊，X线表现需要与其他多种疾病相鉴别。这里，我们报道一例左侧下颌骨动静脉畸形。此患者因拔牙后不可控制的出血转至我院，在止血和维持重要生命体征后在我院行介入与下颌骨刮治术治疗，疗效满意。

Abstract: Mandible arteriovenous malformations are classified as vessel-derived benign tumors. They are easily misdiagnosed and missed due to their low incidence rate, hidden locations, early asymptomatic course, and signs that are not obvious, which cause uncontrollable bleeding and could be fatal. Clinical manifestations are easily misdiagnosed, and X-ray findings need to be differentiated from those of multiple diseases. Here, we present a case of left mandible intraosseous hemangioma in a 50-year-old woman. The patient was transferred to our hospital because of uncontrollable bleeding after tooth extraction, which was treated with curettage and interventional therapy after emergency hemostasis and maintenance of vital signs.

Key words: arteriovenous maformation, mandible, curettage, interventional therapy.
