Clinical Analysis Of Correlation Betwwen Transverse Sinus Drainage Dominance And Aneurysm Formation And Rupture

Objective:To investigate the clinical correlation between transverse sinus classification and variation and aneurysm formation and rupture,and to determine the risk factors of intracranial aneurysm rupture.Methods:A total of 345 cases of intracranial aneurysms were retrospectively enrolled in the study from January to December 2018.Clinical characteristics were compared between ruptured aneurysm group(RAG;n=230)and unruptured aneurysms group(URAG;n= 115),the venous sinus drainage situation burst group and anatomical structure were also analyzed.Logistic regression analysis was performed to analyze the risk factors of nosocomical infection in patients with intracranial aneurysm rupture.Results:the rupture of intracranial aneurysm had statistical significance with the patients’ drinking history,smoking history,hypertension,diabetes,location and size of the aneurysm,as well as the dominant venous sinus on the same side as the aneurysm(P < 0.05).Multivariate logistic regression analysis suggested that diabetes(OR=10.567),anterior communication(OR=2.214),posterior communication(OR=2.932),small aneurysms(OR=3.841),dominant venous sinus on the same side as the aneurysm(OR=1.736)were independent risk factors for rupture of the unruptured aneurysm.In addition,the dominant side of transverse sinus is more likely to form intracranial aneurysms(P < 0.001).Conclusion:The predisposing factors for rupture of intracranial aneurysms are anterior communication,posterior communication,small aneurysms and dominant lateral venous sinuses on the same side as aneurysms.Ipimilateral aneurysms are more likely to form in patients with dominant venous sinuses and can be used to accurately predict aneurysm rupture.
