Pulmonary arteriovenous malformations (PAVMs) are direct traffic between pulmonary arterioles that do not pass through the pulmonary capillary bed, resulting in a right-to-left shunt. Most of them are congenitally inherited, among which they are mainly associated with hereditary hemorrhagic telangiectasia (HTT), also known as Rendu-Osler-Weber disease (ROWD); a few are secondary to pulmonary trauma, chronic lung infections, lung tumors, and liver cirrhosis. Clinically, it may present with hypoxemia, pulmonary hypertension, cerebral infarction, brain abscess, and hemoptysis. In the past, the treatment of PAVMs was mainly surgical. After interventional surgery was applied in the 1980s, it gradually replaced surgical treatment because of its minimally invasive nature, small complications, and high success rate, while interventional treatment is significantly better than surgical treatment for multiple PAVMs in both lungs. Interventional endovascular surgery is transcatheter vascular embolization, which embolizes the abnormal shunted vessels and occludes the malformed vessels to achieve the purpose of treatment. A large number of surgical experience, the domestic leading application of AVP embolization, more economical and practical.
