ABSTRACT
Objective To investigate the value of three-dimensional digital subtraction angiography (3D-DSA)in the diagnosis and interventional treatment of Budd-Chiari syndrome caused by the obstruction of inferior vena cava(IVC).Methods Twenty-one patients with complex Budd-Chiari syndrome caused by the obstruction of IVC underwent 3D-DSA after two-dimensional-DSA(2D-DSA)was performed with posterior-anterior view.The images of 2D-DSA and 3D-DSA were independently reviewed by two senior interventional radiologists iu a double-blinded way.Percutaneous transluminal angioplasty or stent placement of IVC were performed according to the results of 2D-DSA and 3D-DSA.Results Different aspects of the IVC in all patients were demonstrated on the 3D-DSA images,including the mowhology and the location of obstructions,the origins of collateral vessels and their relationships to the IVC.Collateral vessels originated from the site of IVC occlusions in 9 patients were detected by the 3D-DSA.However.the 2D-DSA provided excellent visualization of the vascular structures of the IVC in 7 patients.and the collateral vessels origihated from the site of IVC occlusions were shown in 2 patients.The 3D-DSA was significantly superior to the 2D-DSA in detecting the IVC obstructions and the collateral vessels(P<0.05).The virtual angioscopy of the 3D-DSA was able to visualize free IVC thrombosis in 3 paitents.and mural IVC thrombosis in 1 patient.The procedures were successful in all patients.There were no other complications except the rupture of IVC in 1 patient.Conclusion The 3D-DSA can offer valuable informations in diagnosis of IVC obstruction.and it may play an important role in interventional treatment of Budd-Chiari syndrome.
