Digital Subtraction Angiography-Guided Percutaneous Sclerotherapy of Venous Malformations With Pingyangmycin and/or Absolute Ethanol in the Maxillofacial Region

Digital subtraction angiography-guided phlebography of VMs in the maxillofacial region is one of the approaches to classify VMs using anatomic and hemodynamic features. A strong association was seen between the type of VM and the approach of sclerotherapy. Percutaneous sclerotherapy using pingyangmycin and/or absolute ethanol is a safe and effective method of treating symptomatic VMs.
