Arteriovenous malformations (AVM) are rare in the oral and maxillofacial regions. We report a case of a mandibular gingival AVM in a pregnant woman, who presented at 35 weeks' gestation with massive pulsatile bleeding from a mass in the mandibular gingival margin, which could be managed by local compression and cauterisation. After delivery, the mass gradually regressed. She developed a similar swelling during a second pregnancy. It was thought that increased cardiac output as a result of her pregnancy caused her AVM to progress.
动静脉畸形（AVM）在口腔颌面部区域较为罕见。我们报告一例孕妇下颌牙龈动静脉畸形病例，该孕妇在妊娠35周时，下颌牙龈边缘肿物出现大量搏动性出血，可通过局部压迫和烧灼进行处理。分娩后，肿物逐渐消退。她在第二次怀孕时出现了类似的肿胀。据认为，怀孕导致的心输出量增加使她的动静脉畸形病情进展。
