(A) Preoperative CT shows subarachnoid hemorrhage. (B–C) Preoperative CTA suggests anterior communicating artery aneurysm. (D) Intraoperative puncture of the lateral ventricle to release cerebrospinal fluid for decompression. (E–I) Separation and clipping of aneurysms by neuroendoscopy. (J) Postoperative CT shows aneurysm clip. (K) Postoperative CT scan revealed ventricular drainage tube. (L,M) Postoperative 3D Slicer reconstruction of virtual reality images of lateral ventricles and extraventricular drainage tubes. (N,O) Postoperative CTA indicates complete occlusion of the anterior communicating artery aneurysm, with no stenosis in the parent artery and branches. (P) Surgical incision and bone window.
