Figure 3.

Operation of bilateral carotid artery stenosis. After the skin is cut, blunt dissection with a small clamp or forceps is conducted until the trachea can be seen. Expose both common carotid arteries from their sheaths under an operating microscope. Separating the carotid from the vagus nerve (green arrows) is very important and attention should be paid not to damage the nerve. Sutures should be located around the CCA for lifting the vessels (a). Then twine the microcoil (yellow) by rotating it around the left CCA (b) and right CCA (c).
