目的 通过观察胆囊管正常变异的X线表现 ,探讨胆囊管正常变异的X线表现及临床病理学意义。方法 观察和测量84例直接法胆系造影中显影良好的胆囊管。结果 胆囊管变异发生率 78.6 %。其中胆囊管长度变异占 41.7% ,汇入位置变异占35 .7% ,汇入方向变异占 5 2 .4% ,与肝总管并、绕行占 47.6 %。 4种变异常有 2～ 4种同时存在。结论 胆囊管正常变异是一种发生率较高的先天异常 ,术前行直接法胆系造影对临床有重要意义。
Objective To observe the X-ray findings of normal variation of cystic duct and explore the X-ray findings and clinicopathological significance of normal variation of cystic duct. Methods 84 cases of direct method of gallbladder imaging in the development of a good cystic duct. Results The incidence of cystic duct abnormalities was 78.6%. Among them, the length of cystic duct was 41.7%, the location of foreign body was 35.7%, the direction of foreign body was 52.4%, and the common hepatic duct was 47.6%. Of the four kinds of mutations, there are often two to four kinds of coexistence. Conclusion The normal variation of cystic duct is a high incidence of congenital anomalies. The direct method of preoperative gallbladder angiography is of clinical significance.
