Differences in SII, WPR, and Hcy levels were compared between unruptured and ruptured patients in the unstable small SIAs group, and the area under the curve was plotted to predict the risk of aneurysm rupture. (a) The initial SII level was significantly different between the two groups(median 417.14 vs 2445.29, p < 0.001). (b) The initial WPR level was significantly different between the two groups (median 2.49 vs 5.19, p < 0.001). (c) The initial Hcy level was significantly different between the two groups (median 10.15 vs 12.1, p = 0.005). (d) The initial SII level predicted the probability of secondary rupture of unstable unruptured aneurysms was 0.955 (95%CI, 0.927–0.983). (e) The initial WPR level predicted the probability of secondary rupture of unstable unruptured aneurysms was 0.879 (95%CI, 0.828–0.931). (f) The initial Hcy level predicted the probability of secondary rupture of unstable unruptured aneurysms was 0.619 (95%CI, 0.538–0.7). Compared with patients with unruptured aneurysms, the SII, WPR and Hcy of patients with ruptured aneurysms were significantly higher. And it has a good predictive ability in the risk of secondary rupture in patients with unstable unruptured aneurysm types.
