Pulmonary arteriovenous malformation
Most PAVMs are congenital and occur in patients with HHT, also known as Osler-Weber-Rendu syndrome. They can also occur in acquired conditions such as cirrhosis (most common), penetrating chest trauma, mitral stenosis, schistosomiasis, actinomycosis, Fanconi syndrome, and thyroid carcinoma. Some are idiopathic. The cause of PAVM is unknown.
