【摘要】 目的探讨肝尾状叶静脉分别在正常人群和Budd-Chiari患者中的显示以及测量显示的直径,并评价肝尾状叶静脉在Budd-Chiari综合征的诊断价值。方法 14例Budd-Chiari综合征MRI资料(Budd-Chiari组)和54例上腹部MRI增强检查阴性病例(正常组),在横断位上观察正常组和Budd-Chiari组肝尾状叶静脉的显示,分别计算其显示率,测量正常组和Budd-Chiari组显示肝尾状叶静脉直径,在其下腔静脉汇入口处测量,并进行比较。结果在MRI横断位上,两组病例中显示的肝尾状叶静脉都为一支,汇入下腔静脉左前壁或前壁,54例正常组显示4例,显示率为7.4%,显示直径为0.2~0.34 cm,平均0.26 cm;14例Budd-Chiari组显示9例,显示率为64%,显示宽径为0.4~1.69 cm,平均0.73 cm。Budd-Chiari组肝尾状叶静脉的显示率及显示直径大于正常组,差别有统计学意义(P<0.05)。结论在综合判断肝脏形态及血供的前提下,肝尾叶静脉显示及扩张且扩张直径≥0.4 cm,要高度怀疑Budd-Chiari综合征的可能。更多还原

【Abstract】 Objective To study the diameter of visible hepatic caudate vein in healthy people and patients with Budd chiari syndrome respectively,and evaluate value of hepatic caudate vein in diagnosis of Budd chiari syndrome. Methods 14 patients with Budd chiari syndrome( Budd chiari groups) and 54 healthy people( healthy groups) received upper abdominal enhanced MRI,the visibility of hepatic caudate vein was observed on cross section imaging in Budd chiari groups and healthy groups,rate of visibility was calculated respectively,the diameter of visible hepatic caudate vein was measured at site of confluence of its inserting into inferior vena in Budd-chiari groups and healthy groups,and results were compared between two groups. Results On cross section imaging,the visible hepatic caudate vein was 1 ramus in two groups,inserting into left anterior wall or anterior wall,hepatic caudate vein was noted in 4 of 54 healthy peoples,rate of visibility was 7. 4%,the diameter was 0. 2- 0. 34 cm,average value was 0. 26 cm,hepatic caudate vein was noted in 9 of 14 patients with Budd chiari syndrome,rate of visibility was 64%,the diameter was 0. 4- 1. 69 cm,average value was 0. 73cm. Visibility rate and diameter of hepatic caudate vein were more observed in Budd chiari groups than that in healthy groups, there was a significant difference between two groups( P < 0. 05). Conclusion Visibility and dilation of hepatic caudate vein can be considered as a valuable sign,when diameter of visible hepatic caudate vein is more than 0. 4 cm,Budd chiari syndrome must be highly suspected.更多还原
