Abstract: Objective This study reports the experience of predicting surgical results through the anatomical characteristics of aneurysms.Methods Continuous cases of aneurysm clipping in neurosurgery were collected Statistics include patient demographic data,imaging features and surgical procedures The Glasgow Outcome Score (GOS) at discharge,6 months and 1 year after discharge were analyzed.Results Samong 300 patients with anterior communicating aneurysms,267 were ruptured and 33 were unruptured The mean GOS score was 4.6±0.7 The GOS score of ruptured anterior communicating artery aneurysms was correlated with hunt Hess score,frontal lobe hemorrhage and the need for multiple aneurysm clipping during operation.132 aneurysms originated from anterior communicating artery,12 from A1 segment and 3 from A2 segment;153 cases originated from A1 / A2 junction There were 108 cases of aneurysm protruding upward,97 cases protruding downward,88 cases in the front and 7 cases in the back Aneurysms originated from segment A1 and had the worst prognosis Aneurysms with posterior orientation are less likely to rupture and are usually larger than other types of aneurysms.Conclusion The location,direction and surrounding neurovascular anatomy of anterior communicating aneurysms are helpful to predict the surgical results.Understanding the unique anatomical structure of each aneurysm is very important to obtain the best surgical effect.
