Preoperative and postoperative imaging examination and intraoperative findings of ruptured middle cerebral aneurysm with reconstruction clipping via supraorbital lateral keyhole approach. a, b The ruptured aneurysm was clipped with 3 aneurysm clips. The arrow is the aneurysm clip. c The arrow is the aneurysm at the M1M2 bifurcation of the right middle cerebral artery. d Postoperative CTA revascularization of the head showed that the aneurysm was completely clipped and the branch vessels were preserved. e The aneurysms were clearly exposed after temporary occlusion of the IA carrying vessels. f After clipping of three aneurysms, complete clipping was seen. (M1: M1 segment of middle cerebral artery; M2: M2 segment of middle cerebral artery; IA: cerebral aneurysm)
