Article Title: Intentional staged embolization via the “highway bypass” using a radial artery graft for a large posterior circulation aneurysm: illustrative case
doi: 10.3171/CASE24527
Figure Lengend Snippet: A: Axial T2-weighted MRI showed a mass-occupying lesion with compression of the left internal capsule and thalamus from below ( white arrow ). B: Cerebral angiography showed an unruptured cerebral aneurysm formed in the left P1 segment of the posterior cerebral artery ( white arrow ), with bilateral occlusion of the ICAs. C: Three-dimensional rotational angiography showed a broad-necked aneurysm with a maximum diameter of 22 mm in the left P1 segment. D: Three-dimensional computed tomography angiography showed bilateral VAs with marked tortuosity at the origin and distal portion ( white arrows ).
Article Snippet: The aneurysm, including the left P1, was embolized with coils (16 mm × 50 cm × 2, Target XL 360 standard, Stryker; 12 mm × 40 cm × 3, Axium 3D, Medtronic; 10 mm × 30 cm × 1, Axium 3D; 9 mm × 25 cm × 1, Galaxy G3, Cerenovus; 8 mm × 24 cm × 1, Galaxy G3; 8 mm × 20 cm × 2, Axium 3D; 6 mm × 20 cm × 2, Axium Prime 3D; 5 mm × 20 cm × 1, Axium Prime Helix; and 4 mm × 12 cm × 4, Axium Prime 3D; and ).
