Hybrid treatment of an aortic pseudoaneurysm arising at the innominate artery junction secondary to superior vena cava stenting

Abstract

Pseudoaneurysm of the innominate artery secondary to superior vena cava stenting has never been reported. We report the case of a 42-year-old woman previously treated for a Masaoka stage III thymoma with superior vena cava replacement through median sternotomy followed by adjuvant radiation therapy. Four years later, the patient came back with a large pseudoaneurysm at the junction of the innominate artery and ascending aorta. To avoid resternotomy, endovascular deployment of a stent graft in the ascending aorta with a periscope stenting in the left common carotid artery after axilloaxillary bypass was performed to treat this aortic pseudoaneurysm.
