目的 评价大、小肾下型腹主动脉瘤(AAA)的CT形态学特点.方法 对45例肾下型AAA患者行64层螺旋CT血管成像(CTA),并测定AAA形态学指标.以直径5 cm为界,将患者分为大、小AAA两组,比较两组AAA的临床危险因素及形态学差异,分析瘤体大小与其他形态学特点的相关性.结果 大AAA患者(n=25)收缩压小于小AAA(n=20)(P＜0.05),吸烟比例大于小AAA(P＜0.05).大AAA瘤体长度、近远端瘤颈直径、后壁血栓分布几率及瘤壁钙化积分大于小AAA(P＜0.05).AAA瘤体长度与近端瘤颈角度(r=0.418,P＜0.01)及近端瘤颈直径呈正相关(r=0.411,P＜0.01),与入口角度(r=-0.478,P＜0.01)及近端瘤颈长度呈负相关(r=-0.562,P＜0.01).结论 肾下型AAA的瘤体大小与其他形态学特点具有一定的相关性.
目的 評價大、小腎下型腹主動脈瘤(AAA)的CT形態學特點.方法 對45例腎下型AAA患者行64層螺鏇CT血管成像(CTA),併測定AAA形態學指標.以直徑5 cm為界,將患者分為大、小AAA兩組,比較兩組AAA的臨床危險因素及形態學差異,分析瘤體大小與其他形態學特點的相關性.結果 大AAA患者(n=25)收縮壓小于小AAA(n=20)(P＜0.05),吸煙比例大于小AAA(P＜0.05).大AAA瘤體長度、近遠耑瘤頸直徑、後壁血栓分佈幾率及瘤壁鈣化積分大于小AAA(P＜0.05).AAA瘤體長度與近耑瘤頸角度(r=0.418,P＜0.01)及近耑瘤頸直徑呈正相關(r=0.411,P＜0.01),與入口角度(r=-0.478,P＜0.01)及近耑瘤頸長度呈負相關(r=-0.562,P＜0.01).結論 腎下型AAA的瘤體大小與其他形態學特點具有一定的相關性.

Objective To evaluate the morphological characteristics of large and small infrarenal abdominal aortic aneurysm (AAA) with 64-slice spiral CT angiography (CTA). Methods Forty-five patients with infrarenal true AAA underwent CTA. The morphological characteristics of AAA were evaluated. The patients were divided into two groups: small AAA (diameter<5 cm, n=20) and large AAA (diameter≥5.0 cm, n=25). The clinical risk factors and morphological characteristics between small and large AAA were compared. The correlation between the size of AAA and the other morphological characteristics was analyzed. Results Compared to patients with small AAA, those with large AAA showed lower systolic blood pressure and larger prevalence of smoking (P＜0.05). The length of aneurysms body, diameter of proximal and distal neck, the prevalence of thrombus in posterior wall, and aneurysm wall calcification score in large AAA were significantly larger than those of small AAA (P＜0.05). The length of AAA was positively correlated with proximal neck angle (r=0.418, P＜0.01) and diameter (r=0.411, P＜0.01), whereas negatively correlated with entry angle (r=-0.478, P＜0.01)and proximal neck length (r=-0.562, P＜0.01). Conclusion The size of infrarenal AAA is associated with the other morphological characteristics.
