2、照组进行比较分析。结果：ICA-PCoA动脉瘤患者年龄31~73岁，平均（49.64±12.50）岁，高峰段为40~50岁。男性17例，占41.46%，女性24例，占58.54%。18例（43.9%）有高血压史。3例为多发性动脉瘤，均为两侧各有1个ICA-PCoA动脉瘤。在44个ICA-PCoA动脉瘤中，26个位于右侧，18个位于左侧。ICA-PCoA动脉瘤患侧颈内动脉C1段、C2段平均夹角（90.80±22.87°）显著小于对侧（99.34±19.70°，P＝0.002）和对照组（114.33±34.98°，P＜0.001）。结论：ICA-
3、PCoA动脉瘤的形成可能与高血压和颈内动脉C1、C2段转折处夹角大小有关。关键词颅内动脉瘤；颈内动脉；后交通动脉；形态学特征TheFormationofInternalCarotid-PosteriorCommunicatingArteryAneurysmAnAnalysisofMorphologicalFactorsXu-YingHe,Chuan-ZhiDuan,Tie-LinLi,Ru-XiangXu,Qiu-JingWang,Xue-GanLianDepartmentofNeurosurgery,ZhujiangHospital,Sou
