Objective:
The aim of this study was to determine the incidence and etiology of pulmonary artery pseudoaneurysms in patients undergoing bronchial angiography for massive hemoptysis and to assess patient outcome after the embolization of these pseudoaneurysms.
Conclusion:
Peripheral pulmonary artery pseudoaneurysms occur in up to 11% of patients undergoing bronchial angiography for hemoptysis. These are often most easily appreciated on bronchial and/or nonbronchial systemic arterial angiograms because of complete reversal of flow in pulmonary artery branches in the diseased lung. Embolization of bronchial and nonbronchial systemic arteries alone may not be sufficient therapy to control hemoptysis, and occlusion of the pseudoaneurysm itself via a pulmonary artery approach is recommended.
