Abstract:
Objective To study the clinical significance of the caudate lobe vein in patients with Budd-Chiari syndrome (BCS) by contrast-enhanced magnetic resonance imaging(MRI).Methods Contrast-enhanced MRI data of 46 patients with BCS, 30 patients with cirrhosis due to hepatitis B virus (HBV) and 49 healthy people in our institution were analyzed retrospectively.The presence and diameter of the caudate lobe vein among the three groups were measured.Among the BCS group, in which the caudate lobe vein could be seen, andpatients were divided into two groups according to disease duration and patency of inferior vena cava (IVC), respectively.And comparative study of diameter between two groups was performed.Results ①The caudate lobe vein was noted in 76.1% of patients with BCS, in 30.0% of patients with cirrhosis due to HBV,and in 36.7% of healthy subjects.The diameter of caudate lobe vein in BCS group was larger than that in both cirrhosis group and healthy group(P<0.01).There was no statistically difference between cirrhosis group and healthy group(P>0.05).②Among BCS group,the caudate vein was shown in 35 patients, with mean diameter of(4.21±1.66)mm.For 35 BCS,the diameter of caudate lobe vein in chronic group was larger than that in acute group(P<0.05).The diameter of caudate lobe vein in IVC obstruction group was larger than that in IVC open group(P<0.05).Conclusion The demonstration of the caudate lobe vein on contrast-enhanced MRI is of great significance in the diagnosis and treatment of BCS.
