FIG 3. Bifurcation aneurysm is created by using a venous pouch of external jugular vein after a partial end-to-side anastomosis of the left CCA to the proximal part of the arteriotomy of the right CCA. Side-wall aneurysm is created by using a venous pouch of the external jugular vein with slight oblique orientation, and a small branch-artery aneurysm is created by using a venous pouch of the anterior facial vein at the junction of the CCA and cranial thyroid artery (asterisk).
