Clinical Studies

OBJECTIVE: Endovascular stenting is an alternative treatment for brachiocephalic artery stenosis, replacing standard surgical approaches such as carotid endarterectomy. However, a percutaneous approach may be difficult because various conditions such as severe arteriosclerosis of iliac or femoral arteries and aortic disease. We report our experience with intraoperative stenting for these lesions, presenting indications, strategy, and results.

METHODS: Seven patients underwent intraoperative stent placement via an open cervical approach. The sites of lesions included 1 innominate artery, 1 common carotid artery, and 5 cervical carotid arteries. Stenting was performed with a sheath introducer placed through a surgically exposed common carotid artery via a small skin incision or common carotid artery exposed for simultaneously performed carotid endarterectomy. Distal protection was used in 6 patients with an endovascular protective balloon or external clamping with forceps.

RESULTS: Sufficient dilation of stenosis was obtained in all cases. No complications such as transient ischemic attack, cerebral infarction, and hyperperfusion were encountered. Wound hematoma was not experienced despite perioperative antiplatelet therapy and heparinization during the procedure. Angiographic follow-up over 1 year showed no restenosis in 5 available patients.

CONCLUSION: Intraoperative stenting may be an excellent alternative for patients in whom both direct surgical approach and standard percutaneous endovascular approach are not possible.
