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
Objective: To investigate the CT findings of spontaneous traffic in portal hypertension and splenic vein and its clinical value in the diagnosis. Materials and Methods: A retrospective analysis of 980 patients with cirrhosis, portal hypertension leading to splenic vein and left renal vein spontaneous traffic and other collateral circulation open CT enhanced performance characteristics. Results: 18 cases of splenic vein and left renal vein spontaneous traffic were found by CT enhanced scanning. The splenomegaly and the left renal vein showed columnar and lumpy homogeneous enhancement with sharp edge. Splenic vein and left renal vein significantly thicker, distorted. Conclusions: CT enhanced CT can clearly diagnose the presence of spontaneous traffic in splenic vein and left renal vein in patients with portal hypertension and is associated with left adrenal tumor and enlarged lymph node, which is of great value in the diagnosis and differential diagnosis
