Abstract Objective: To investigate the relationship between the aspect ratio (AR) of the anterior communicating artery (AComA) aneurysm and aneurysm rupture. Methods: A retrospective analysis of 650 consecutive patients with single AcoA aneurysms between October 2010 and January 2016 in the First Affiliated Hospital of Wenzhou Medical University was conducted. There were 578 patients with ruptured AcomA aneurysms and 72 with un-ruptured AcomA aneurysms. The diameter of perpendicular height and aneurysm neck was re-measured using CT angiography images and the relationship between the AR and aneurysm rupture status was analyzed. Results: In ruptured aneurysm group, the perpendicular height was (3.57±1.96) mm, the neck size was (3.07±1.17) mm, and the AR was 1.24±0.67. In un-ruptured aneurysm group, the perpendicular height was (2.59±1.85) mm, the neck size was (2.71±1.15) mm, and the AR was 0.97±0.60. The perpendicular height, neck size and AR of ruptured aneurysms were larger than the unruptured, with significant difference (P<0.05) between them. The AR of AComA aneurysms was analyzed by ROC curve. The area under the curve was 0.64, and the optimal cut-off value was 0.935. Conclusion: The AR size was significantly related to the rupture of AComA aneurysms. In clinical practice, the AR could be considered a reference factor that may aid in risk evaluation of these patients.
