Correlation between blood glucose and aneurysm rupture

Objective To investigate the correlation between blood glucose and aneurysm rupture, and analyze the correlation factors of aneurysm rupture. Methods The clinical data of 128 patients with intracranial aneurysms in the First Affiliated Hospital of Kunming Medical University from January 2017 to August 2018 were retrospectively analyzed. Among them, intracranial aneurysm rupture was in 85 cases (rupture group), and unruptured was in 43 cases (unruptured group). The patient′s clinical features and aneurysm morphological features were recorded. Results The blood glucose, daughter sac rate and regularity of morphology rate in ruptured group were significantly higher than those in unruptured group: (6.74 ± 2.61) mmol/L vs. (5.77 ± 2.11) mmol/L, 60.00% (51/85) vs. 11.63% (5/43), and 68.24% (58/85) vs. 30.23% (13/43), the aneurysm width was significantly smaller than that in unruptured group: (4.53 ± 2.25) mm vs. (5.67 ± 2.68) mm, and there were statistical differences (P 0.05). Univariate Logistic regression analysis result showed that blood glucose, aneurysm width, daughter ascus and irregular shape were the risk factors of rupture of aneurysm (P<0.05 or <0.01). Multivariate Logistic regression analysis result showed that blood glucose, aneurysm width, daughter sac and irregular shape were the independent risk factors of rupture of aneurysm (OR = 1.364, 0.709, 9.441 and 3.935; 95% CI 1.073 to 1.734, 0.565 to 0.889, 2.879 to 30.963 and 1.330 to 11.646; P = 0.011, 0.003, 0.000 and 0.013). The patients were grouped again according to the aneurysm width, and univariate Logistic regression analysis result showed that aneurysm width ≤ 3 mm was the risk factors of rupture of aneurysm (OR = 0.294, 95% CI 0.094 to 0.916, P = 0.035). Conclusions Irregular shape and daughter sac of aneurysm are the independent risk factors of aneurysm rupture, but aneurysm rupture has nothing to do with recent blood sugar levels.
