摘要：
目的 经过256层螺旋CT血管成像技术察看胆囊癌、胆囊炎时胆囊动脉显示状况、能否影响胆囊动脉起源,并测量胆囊动脉管径及横截面积.方法 选取在我院行上腹增强扫描检查并提示胆囊癌、胆囊炎及胆囊未见异常患者的影像资料,观察并记录各组资料胆囊动脉显示率、显示评分、起源,并测量胆囊动脉直径及横截面积.结果 胆囊炎组91例,胆囊动脉显示率96.7%(88/91),其中胆囊动脉起源变异13例(14.8%),88例患者中,显示评分1分19例、2分69例;胆囊癌30例,胆囊动脉显示率96.7%(29/30),其中胆囊动脉起源变异5例(17.2%),29例患者中,显示评分1分3例、2分26例;胆囊正常组100例,胆囊动脉显示率94.0%(94/100),其中胆囊动脉变异16例(17%),94例患者中,显示评分1分58例、2分36例.各组间进行统计分析,胆囊动脉显示率及起源变异无统计学意义( P >0.05),胆囊动脉显示评分有统计学意义( P 0.05). However,the scores of displaying the cystic artery had statistical significance ( P <0.05). As for the measure-ment of the pipe diameter and cross sectional area of cystic artery,in the group of cholecystitis,there were 98 pieces,with an av-erage of (1.99 ± 0.39) mm in the pipe diameter and with an average of(3.30 ± 1.25) mm2in the cross sectional area of cystic artery;in the group of gallbladder carcinoma,there were 30 pieces,with with an average of(2.44 ± 0.69) mm in the pipe diam-eter and with an average of(5.11 ± 3.46) mm2in the cross sectional area of cystic artery;and in the group of normal gall-blad-der,there were 101 pieces,with an average of (1.78 ± 0.30) mm in the pipe diameter and with an average of (2.59 ± 0.83)mm2in the cross sectional area of cystic artery. Compared the results in each group, there were significant differences ( P <0.05). Conclusion 256-slice spiral CT angiography can evaluate cystic artery well,which can be used as preoperative examina-tion for laparoscopic cholecystectomy.
