Iatrogenic pulmonary artery rupture

The incidence of pulmonary artery ruptures is probably underestimated because many hemoptysis episodes or radiological infiltrations associated with pulmonary artery catheter use are not investigated. Also, the natural evolution of the pulmonary artery false aneurysm is unknown. The incidence of spontaneous healing, bleeding recurrence or asymptomatic persistence is unknown following formation of a pulmonary artery false aneurysm.
