Intraoperative Innominate and Common Carotid Intervention Combined With Carotid Endarterectomy: A “True” Endovascular Surgical Approach

PURPOSE: To report the technique of carotid endarterectomy (CEA) combined with retrograde balloon angioplasty and stenting of proximal "tandem" lesions in the supra-aortic trunk. TECHNIQUE: Intraoperative techniques in 34 patients with 23 left common carotid artery (CCA) and 11 innominate artery lesions included general anesthesia, low-dose dextran, prosthetic patching, selective shunting, 8-F sheath entry into the native CCA before the CEA, manual CCA sizing, and balloon-expandable stent placement after predilation. The technique has a high procedural success rate (97%) and appears durable. Over a mean 34-month follow-up, 2 >70% ostial CCA restenoses were found at 24 months. CONCLUSIONS: Intraoperative innominate or left CCA balloon angioplasty/stenting combined with carotid endarterectomy is safe, effective, and durable.
