GOMES, André  and  CAMPOS, Paula. Pulmonary artery pseudoaneurysm: a rare vascular lesion after right heart catheterization. Angiol Cir Vasc [online]. 2017, vol.13, n.1, pp.36-38. ISSN 1646-706X.

Pulmonary artery pseudoaneurysms may be caused by infection, trauma, neoplasm or iatrogenic lesions, such as pulmo- nary artery rupture during right heart artery catheterization. Clinical presentation can range from an incidental finding to a life-threatening bleeding with massive hemoptysis. We present a case of a 67 year old woman with systemic sclerosis that developed massive hemoptysis after right heart catheterization. Computer tomography angiography showed a pulmonary artery pseudoaneurysm in the posterior basal segmental branch of the left lower lobe. Computer tomography angiography usually allows pseudoaneurysm diagnosis, localization and characterization and can aid in therapeutic procedure planning. Without treatment pseudoaneurysms may enlarge or rupture. Although a rare complication, pulmonary artery pseudoa- neurysms are associated with high morbidity and mortality, and should not be missed.
