Arterio-venous malformation (AVM) is a congenital vascular malformation.It results from an error in vascular development during embryogenesis.An absent capillary bed causes shunting of blood directly from the arterial to venous citulation.An AVM is a potentially life-threatening lesion.The AVM remains the most challenging malformation among the various CVMs because it is difficult to treat.A multidisiciplinary team that integrates endovascular and surgical therapy can substantially improve the treatment results seen in patients with AVMs.A successful treatment strategy requires an aecurate assessment of the AVM taking into account the extent, type of A-V shunting, and progression of the lesion.Embelization is no longer just used preoperatively to reduce blood loss during resection.Ethanol embolization is becoming one of the major therapies for AVM.Meanwhile, for AVM patients who are unsuitable to be treated with ethanol embolization,well-designed plastic and reconstructive surgery still play an irreplaceable role in management of AVM.

背景：静脉畸形是常见的体表软组织静脉畸形。到目前为止，对其形态的认识来自普通的静脉造影X线摄片、CT平扫、MRI平扫和微观的病理结构观察，对其立体形态的观察尚未见报道。方法：我们采用向静脉畸形窦腔内注射造影剂碘普罗胺、注射后立刻行CT扫描、然后再进行三维重建的方法成功获得静脉畸形的三维成像。结果：根据血液回流的特征，我们将静脉畸形分为快速回流型和慢速回流型。快速回流型静脉畸形有粗大的回流静脉，与主
