Abstract:

Objective To evaluate the value of CTA in the diagnosis of anterior communicating artery aneurysms（ACoAA）and to analyze the relationship between ACoAA and the variation of horizontal segment of anterior cerebral artery. Methods 68 patients with ACoAA confirmed by DSA were selected as study group，all patients underwent CTA scan of the head and neck，the neck width and maximum diameter of ACoAA were mea⁃ sured on CTA and DSA images，and statistically compared，and 88 cases of cerebral vascular CTA images without intracranial aneurysms in the same period were taken as control group，and the relationship between the horizontal segment variation of anterior cerebral artery and ACoAA was compared between the two groups. Results The detection rate of ACoAA by CTA was 100%. There was no significant difference in the neck width and maximum diameter between CTA and DSA images（P > 0.05）. In the patients with ACoAA，the incidence of A1 segment variation of the anterior cerebral artery was significantly higher than that in the control group （P < 0.001）. Conclusion CTA can verify the existence of ACoAA and accurately measure the neck width and tumor size. There is a relationship between the occurrence of ACoAA and the variation of horizontal segment of the anterior cerebral artery，which provides an important reference for interventional therapy of ACoAA.
