目的：对动脉门静脉造影（CTAP）中CT显示的Retzius静脉根据解剖位置进行分类，并评价CT显示频率与相关疾病的关系。材料和方法：作者回顾了130例患者的轴向CTAP扫描。患者分为两组：肝硬化患者（1组[n = 81]）和无肝硬化患者（2组[n = 49]）。结果：Retzius静脉通路分为：(a)回肠结肠静脉经右性腺静脉汇入下腔静脉或右肾静脉（n = 61）；(b)胰十二指肠静脉引流至下腔静脉（n = 8）；(c)肠系膜上静脉近端分支流入左侧。性腺静脉（n = 6）；(d)回结肠静脉直接引流至下腔静脉（n = 5）。1组81例患者中有41例（51%）出现Retzius静脉，2组49例患者中有26例（53%）出现Retzius静脉。两组间差异无统计学意义。结论：大约50%的肝硬化患者和50%的非肝硬化患者在CTAP上显示了Retzius的静脉作用。
PURPOSE: To classify the veins of Retzius demonstrated at computed tomography (CT) during arterial portography (CTAP) on the basis of anatomic location and to evaluate the relationship between the frequency of CT visualization and associated disease.MATERIALS AND METHODS: The authors reviewed axial CTAP scans from 130 patients. Patients were classified into one of two groups: patients with liver cirrhosis (group 1 [n = 81]) and patients without liver cirrhosis (group 2 [n = 49]).RESULTS: The pathways of the veins of Retzius were classified as follows: (a) The ileocolic vein drained into the inferior vena cava (IVC) or the right renal vein through the right gonadal vein (n = 61); (b) the pancreaticoduodenal vein drained into the IVC (n = 8); (c) the proximal branches of the superior mesenteric vein drained into the left. gonadal vein(n = 6); and (d) the ileocolic vein drained directly into the IVC (n = 5). The veins of Retzius were demonstrated in 41 (51%) of the 81 patients in group 1 and 26 (53%) of the 49 patients in group 2. There was no statistically significant difference between the two groups.CONCLUSION: the veins of Retzius were demonstrated at CTAP in approximately 50% of patients with and 50% of patients without liver cirrhosis.
