FIG. 3.

A: Splitting the sylvian fissure revealed the M2 segment of the ICA trifurcating at the limen insulae; the segment caliber was found to be too small for the graft. B:The cavernous sinus was accessed and filled with cotton packing material. C: Because the cephalic vein was severely mismatched to the M2 branch, the supraclinoid ICA was chosen as the new recipient. D: Anastomosis between the supraclinoid ICA and the cephalic vein was performed after trapping of the supraclinoid ICA distal to the ophthalmic artery and proximal to the choroidal artery, with an additional temporary clip on the posterior communicating artery. E: The CCA and the cephalic vein were sutured after temporary trapping of the CCA. F: Indocyanine green videoangiography confirmed patency of the cephalic vein graft bridging the supraclinoid ICA and CCA.
