Sudden Death Due to a Ruptured Pulmonary Trunk Aneurysm Coexisting With a Saccular Aneurysm of the Ascending Aorta in an Elderly Cigarette Smoker: A Case Report.

The simultaneous occurrence of a pulmonary artery aneurysm and an aortic aneurysm is rare. Both aneurysms can have an insidious course with devastating consequences of rupture, resulting in sudden death. Elderly chronic cigarette smokers are at risk of developing both aortic and pulmonary artery aneurysms. We describe a case of a 75-year-old person whose only other comorbidity was a long history of cigarette usage, who had concurrent aortic arch aneurysm and pulmonary trunk aneurysm, with rupture of the latter causing sudden death.
