Abstract

We report a case of right main pulmonary artery compression due to a type II dissecting aortic aneurysm simulating massive pulmonary artery embolism. Aortic tear and intimal splitting developed around an aortocoronary bypass graft performed 11 months earlier. Ultrasound detected the aortic aneurysm and pulmonary hypertension, and excluded emboli in the pulmonary artery. Pulmonary angiography explained the lung involvement, showing compression of the right main pulmonary artery. Coronary and aortic angiograms demonstrated that the aortic aneurysm developed around the right venous bypass graft. Surgery confirmed the angiographic findings and the pathogenesis of the syndrome.
