Stent placement caused angles to expand. A–C, A 62-year-old female patient had an Enterprise stent deployment for the treatment of a small BA aneurysm. The angle between the right PCA and the BA was 74.63° before stent placement (A), 105.07° immediately following stent placement (B), and 123.18° 7 months later. D–F, A 37-year-old female patient had 2 Neuroform stents deployed in a Y-configuration to treat a BA aneurysm. The angle between the right PCA and the BA was 111.55° before stent placement, 112.55° immediately after stent placement, and 128.72° at 4-year follow-up.

Modified figures show angular changes before and after stent placement and after delayed stent migration. A–D, The angle between the left PCA and the BA was 117.2° before stent placement (A), 145.68° at the end of stent-coiling procedure (B), 148.07° at 3-month follow-up (C), and 134.95° after delayed stent migration at 5-month follow-up (D). Modified with permission from Kelly et al.1 E–G, The angle between the right PCA and the BA was 124.90° before stent placement (E), 125.75° after stent placement (F), and 134.33° after delayed proximal stent migration (G). Modified with permission from Lavine et al.3 H–I, The angle between the left PCA and the BA was 121.02° after stent placement (H) and 109.23° after the stent migrated into the BA 6 months later (I).
