Pulmonary artery aneurysm: a review

Mridul Gupta et al. Pulm Circ. .

Abstract

Pulmonary artery aneurysm is a rare but important entity in the spectrum of pulmonary vascular diseases. The etiologies can be varied and patients can present with non-specific symptoms with the diagnosis being incidental. There is limited consensus regarding the diagnostic criteria and follow-up imaging for patients diagnosed with this entity. Further the management strategies can be variable depending upon underlying disease, etiology, center dependent expertise, and resources available. We review the etiologies, epidemiology, classification, clinical manifestations, and imaging features of pulmonary artery aneurysm. We also review the current management strategies and suggest an algorithmic approach to these patients.

Keywords: congenital cardiovascular malformations; pseudoaneurysm; pulmonary arterial hypertension; vasculitis.
