摘　　要：目的探讨急性胰腺炎累及肝后下腔静脉前间隙的MSCT表现及其解剖学基础。方法回顾性分析58例经手术病理和／或临床实验室检查证实的Bahhazar CT分级C级及其以上的急性胰腺炎患者的MSCT资料，着重观察肝后下腔静脉前间隙受累的CT表现及其受累途径，并分别记录Balthazar CT分级。结果①58例患者中13例表现为肝后下腔静脉前间隙受累，其中D级1例，E级12例；②肝后下腔静脉前间隙受累表现为该间隙增宽，正常脂肪密度被水肿、浸润增厚的弥漫性或局限性软组织密度或液性密度替代；③Balthazar CT分级C，D和E级与肝后下腔静脉前间隙的受累率有统计学意义。结论急性胰腺炎肝后下腔静脉前间隙受累表现为不同程度的炎性改变；MSCT可以清楚显示急性胰腺炎累及肝后下腔静脉前间隙的解剖细节。Objective To evaluate MSCT features and anatomic basis of retrohepatic tunnel（RT） involvement in acute pancreatitis. Methods The MSCT images of 58 patients with acute pancreatitis（belonged to C grade and above aecording to Balthazar＇s CT criterion） proved by surgery,clinical and laboratory findings were analyzed retrospectively. We focused on observation of the CT features and the pathway of RT involvement. The Balthazar CT classification were recorded. Results （1） In 58 patients, 13 patients showed RT involvement,and 1 case belonged to D grade, 12 cases belonged to E grade. （2）The RT involvement showed that the space widened and the normal fat density was replaced by diffuse or localized soft-tissue density or fluid density. （3）There was significant difference in the incidence rate of RT involvement among C,D and E grade. Conclusion RT involvement in acute pancreatitis showed different degree of inflammatosy changes,and MSCT can clearly demonstrate the details of the RT involvement in acute pancreatitis.
