Wall Stress in Giant Aneurysm of the Pulmonary Artery: A Possible Guide to Therapy

 Wall Stress in Giant Aneurysm of the Pulmonary Artery: A Possible Guide to Therapy

Pulmonary artery aneurysm in adults is a rare diagnosis, most frequently reported in association with congenital heart disease or pulmonary arterial hypertension. Best therapeutically approach to pulmonary artery aneurysm in asymptomatic adults is disputed. We present the case of a 66-year old man with incidental finding of a true aneurysm of the common pulmonary artery. We discussed the impact of pressure fall and/or conduit diameter reduction on wall stress and likelihood of aneurysm rupture, therefore suggesting a potential rationale to support a most effective therapeutic approach in rare cases.
