目的总结胰腺损伤脾静脉的CT征象,评价其在胰腺损伤CT诊断中的作用。方法搜集经手术证实4例和经临床表现、实验室、CT表现证实6例胰腺损伤病人的CT检查资料,观察和分析脾静脉的变化。结果10例胰腺损伤病人脾静脉均有改变,CT平扫脾静脉分辨不清,CT增强扫描包括弧形征3例,S征3例,V征分为浅V征和深V征均为3例,僵直征4例。结论CT能较准确反映胰腺损伤脾静脉的变化;结合胰腺及胰周的CT表现,能准确显示胰腺损伤的部位、程度及并发症,并能初步判断脾静脉损伤的部位、程度。
Objective To summarize CT findings of splenic vein in pancreatic injury and evaluate its role in CT diagnosis of pancreatic injury. Methods Four cases confirmed by operation and CT examination data of 6 cases of pancreatic injury confirmed by clinical manifestation, laboratory and CT were collected to observe and analyze the changes of splenic vein. Results The splenic veins of 10 patients with pancreatic injury were changed. The splenic vein was not clearly identified by CT. CT scan included 3 cases of arc sign, 3 cases of S sign, 3 cases of V sign and 3 cases of V sign Cases, stiff sign in 4 cases. Conclusions CT can accurately reflect the changes of splenic vein in pancreatic injury. Combined with the CT findings of pancreas and peripancreatic, it can accurately show the location, degree and complications of pancreatic injury, and can preliminarily determine the location and degree of splenic vein injury.
