Arteriovenous malformation (AVM) of the head and neck is a rare phenomenon, more so when it is an extracranial AVM like the auricle. AVMs are caused by genetic mutations. Most are probably present in the subclinical form at birth and then evolve; some may arise postnatally or during adolescence or get aggravated by precipitating factors like trauma, infection or hormonal influence like puberty or pregnancy. Once diagnosed, the feeding vessels have to be identified using radiological investigations. They are then embolised via means of percutaneous embolisation and surgical resection.
头颈部动静脉畸形(AVM)较为罕见,尤其是发生在耳廓等颅外部位的 AVM 更为少见。AVM 是由基因突变引起的。大多数可能在出生时即处于亚临床状态,然后逐渐发展;有些可能在出生后、青春期或由创伤、感染或青春期、妊娠等激素影响等诱发因素引起。一旦确诊,就需要使用影像学检查来识别供养血管。然后通过经皮栓塞和手术切除来栓塞供养血管。
