Hybrid surgery for a severe infectious innominate artery pseudoaneurysm compressing the main trachea

Here, we report a case of an infectious pseudoaneurysm at the root of the innominate artery, compressing the trachea, that resulted in massive hemorrhage due to rupture of the innominate artery. The patient, a 31-year-old man, had complained of persistent fever for 40 days and severe dyspnea for 1 week. Contrast-enhanced computed tomography imaging of neck and thorax showed a pseudoaneurysm originating from the root of the innominate artery that was severely compressing the main trachea. A hybrid surgery strategy was applied. We first implanted a covered stent in the root of the innominate artery. Then, we performed a left-to-right carotid−carotid bypass with a great saphenous vein graft. Finally, we performed a median thoracotomy in which both the pseudoaneurysm and the previously implanted covered stent were successfully extracted. The patient lost strength in the right upper limb muscle on postoperative day 2 but recovered to baseline strength after 3 months. A hybrid surgical technique may represent a practical solution for such conditions.
