【摘要】 目的：探讨门脉高压脾静脉与左肾静脉自发交通的ＣＴ表现及其在诊断中的应用价值。材料与方法：回顾性分析９８０例肝硬化患者，门脉高压导致脾静脉与左肾静脉自发交通及其他侧支循环开放的ＣＴ增强表现特征。结果：ＣＴ增强扫描发现１８例脾静脉与左肾静脉自发交通，表现为脾门与左肾静脉之间柱状、团块状均匀强化影，边缘光整、锐利。脾静脉与左肾静脉明显增粗、扭曲。结论：ＣＴ增强扫描能明确诊断门脉高压时有无脾静脉与左肾静脉自发交通存在，并与左肾上腺肿瘤和肿大淋巴结鉴别，在诊断与鉴别诊断中具有重要的应用价值更多还原

【Abstract】 Objective: To investigate the CT characteristics of spontaneous splenorenal shunt in portal hypertension. Materials and Methods: The enhanced CT findings of 980 cases with cirrhosis were analyzed retrospectively. Results: Eighteen cases of spontaneous splenorenal shunt were found. On enhanced CT scan, the shunt represented as columnar or massive uniformlyenhanced sharplybordered structure between the splenic and left renal veins, which were significantly enlarged and twisted and enable to be differentiated with adrenal tumor or lymph node. Conclusion: Enhanced CT scan can confirm the existence of spontaneous splenorenal shunt or other collateral channels occasionally seen in portal hypertension, and can also differentiate the shunt from adrenal tumor or lymph node.更多还原
