Pulmonary arterio-venous malformation

ABSTRACT

Pulmonary arterivenous malformation [PAVM] is an abnormal communication between the pulmonary and the pulmonary vein. PAVMs are usually congenital in origin. In this study we reported 32-year-old women that referred to the clinic with the chief complain of frequently coughs and hemoptysis for three months. Also her past medical history revealed that she had a thoracotomy and decortication of the right lung due to clotted hemothorax, about 12 years ago while she had a term pregnancy. CT angiography and spiral CT-scan demonstrated in the right hemithorax. These masses were enhanced like pulmonary vessels and had feeding artery and evacuator vein. So three PAVMs were diagnosed in the right lung. The patients underwent right postrolated thoracotomy. Two of the PAVMs were in the lower lobe which treated by resection but the one in the middle lobe was performed
