A rare case of a simultaneous post-dissection saccular aneurysm of the ascending aorta and large pulmonary artery aneurysm with secondary embolism: a case report.

ABSTRACT

BACKGROUND: Aneurysms of the pulmonary arteries and the ascending aorta are rare, and both bear a high mortality risk if left untreated. In general, these entities are primarily caused by etiologies such as hypertension, pulmonary arterial hypertension, infection or congenital disorders. Treatment requires a rapid diagnostic work-up or even immediate surgical intervention in acute cases. Nevertheless, surgery entails serious perioperative risks, in particular in patients with multiple comorbidities. CASE PRESENTATION We discuss a 70-year-old woman presented with decompensated heart failure based on severe pulmonary artery hypertension, coincided by a massive pulmonary artery aneurysm with secondary embolism. Additional diagnostic imaging also showed a chronic post-dissection, saccular aneurysm of the ascending aorta. To our knowledge, this simultaneous diagnosis of a saccular aneurysm of the ascending aorta and a large aneurysm of the pulmonary artery with secondary embolism has not yet been described. Nonetheless, conservative treatment was chosen due to extensive pulmonal and cardiovascular comorbidities and the high-risk profile of surgery. CONCLUSIONS: Extensive aneurysmatic disease of the pulmonary arteries and ascending aorta come with a serious burden of disease, especially if coincided by severe pulmonal and cardiovascular comorbidities. Both conditions can be curatively treated by surgical intervention. However, in every case the risk of surgery and the patient's vitality, comorbidities and wishes should be taken into account to formulate an adequate treatment plan. Therefore, shared decision making is of utter importance.
