Abstract：Objective To analyze the formation of internal carotid-posterior communicating artery aneurysm by detecting the size of the angle between the ophthalmic segment and origin of the posterior communicating artery (Apcom), the angle between ophthalmic and communicating segment of the internal carotid artery (Aica) and the angle between the communicating segment of the internal carotid artery and origin of the posterior communicating artery (Apcom') with 3D-DSA. Methods The clinical data of 24 patients with internal carotid-posterior communicating artery aneurysm (aneurysm group) and 22 patients without any aneurysm (control group) were analyzed retrospectively. The 3-dimensional models of involved arteries were constructed for analyzing the morphological features. Results Statistically significant differences were found in the value of Apcom, Aica, Apcom', sex and age between the two groups (P<0.05). Only Apcom (P=0.008) and Aica (P=0.007) were independent associations with the formation of internal carotid-posterior communicating artery from the logistic regression. The area under ROC curve (AUC) of Apcom was 0.799 (95%CI:0.661~0.938), and the threshold for optimal diagnosis was 100.2.. The AUC of Aica was 0.764 (95%CI:0.622~0.906), and the threshold for optimal diagnosis was 113.3.. Conclusion The formation of internal carotid-posterior communicating artery aneurysm may be associated with the sizes of Apcom and Aica.
