From: Usefulness of intraoperative Indocyanine green video angiography to select the recipient artery for bypass surgery in arteriosclerotic occlusion of the middle cerebral artery: a technical case report

Fig. 2

A, B, C: Intraoperative microscopic photographs. (a) After dissection of the Sylvian fissure, the M1–2 bifurcation of the middle cerebral artery is exposed (asterisk: M2 inferior trunk). (b) After dissection of the M2 inferior trunk from the proximal side, the occluded portion is long. (c) There are several M4 cortical arteries on the brain surface (arrows: Sylvian fissure, F: frontal lobe, T: temporal lobe). D, E, F: Intraoperative indocyanine green video angiography in the same view as C. (d) In the early phase, M4 cortical arteries fed by the superior trunk show luminescence. (e) A short time later, M4 cortical arteries fed by the inferior trunk show luminescence. (f) In the late phase, M4 cortical arteries fed by the inferior trunk still show luminescence. (arrows: M4 cortical arteries fed by the inferior trunk)
