Embolization and imaging follow-up of an unruptured left middle cerebral artery (MCA) bifurcation aneurysm. (A) A 57-year-old woman was admitted for treatment of a left middle cerebral artery aneurysm diagnosed by CTA. (B) Orthostatic cerebral angiography revealed a wide-necked bifurcation aneurysm in the left MCA. (C) 3D reconstruction showing the left MCA aneurysm involving three middle cerebral artery branches, and Y-stent-assisted embolization was proposed for treating the aneurysm. (D) Postoperative 3D angiography showing embolization of the aneurysm in the left MCA bifurcation. (E,F) The 3D reconstruction reveals the embolization status of the aneurysm at the bifurcation of the left MCA. The embolization result is classified as mRRC III b, with partial opacification observed in the aneurysmal sac. (G,H) Postoperative orthopantomography and 3D reconstruction demonstrating improvement in the embolization of the aneurysm located in the branch of the left MCA at the seventh month after surgery, with the aneurysm completely and densely embolized to mRRC I.
