Abstract:
OBJECTIVETo evaluate magnetic resonance venography (MRV) in diagnosing obstructive interface morphology of Budd-Chiari syndrome(BCS).
METHODSMRV examination was performed on 44 cases of BCS, and the images of obstructive interface morphology of the inferior vena cava were reviewed by two radiologists.
RESULTSIn all 44 cases, there were 37 cases with complete obstruction and 7 with incomplete obstruction. MRV showed 4 cases with membrane with hole of incomplete obstruction. The morphologies MRV demonstrated that the proximal part of the 37 cases with complete obstruction were mainly divided into the cone type (36 cases) and the planum type (1 case). Besides, the type of distal end of obstruction were the cone type (30 cases), the planum type (4 cases) and the irregular type (3 cases). The overall sensitivity, specificity, positive and negative predictive values for the diagnosis of MRV were respectively 100%%, 57.1%, 92.5% and 100% as compared to the DSA.
CONCLUSIONThe examination of MRV is capable of revealing the obstructive interface morphology of the inferior vena cava, especially for the distal end of obstruction. MRV can provide guidelines in interventional treatment of Budd-Chiari syndrome.
