Sternum-Sparing Hybrid Repair of a Symptomatic Innominate Artery Aneurysm in a Frail Patient with Bovine Aortic Arch

We present the case of a 65-year-old man with a bovine aortic arch variation, who presented a symptomatic aneurysm of the innominate artery. Standard open repair was contraindicated and an hybrid approach was performed, regarding general status (Organisation Mondiale de la Santé (OMS) Performance Status score 3 and American Society of Anesthesiologists Physical Status classification system score 3). Right common carotid artery and right subclavian artery were revascularized surgically from the left common carotid artery. Proximal aneurysm exclusion was performed with a vascular plug. Follow-up computed tomography angiography confirmed the exclusion of the innominate artery aneurysm. Vascular plugs can be used safely through a sternum-sparing hybrid approach to treat symptomatic innominate artery aneurysms in frail patients.
