Mesoinnominate shunt for the treatment of Budd-Chiari syndrome: evaluation with multimodality imaging.
The construction of a mesoinnominate shunt between the superior mesenteric vein and the left innominate vein is a recent surgical procedure for the treatment of Budd-Chiari syndrome with vena caval obstruction. The purpose of this study was to determine the role of the different imaging modalities for the follow-up of mesoinnominate shunts. Doppler US (n = 32), and MR imaging examinations (n = 32) were prospectively performed in 10 patients with mesoinnominate shunts. Shunt patency or thrombosis was confirmed with angiography (n = 32) and transhepatic portography with pressure measurement (n = 6). For each follow-up evaluation, all examinations were performed within 4 days. Shunt patency was correctly demonstrated in 28/28 cases with Doppler US, CT and MR imaging. Shunt thrombosis was correctly demonstrated in 4/4 cases with Doppler US, CT and MR imaging. Since Doppler US, CT and MR imaging have the same accuracy for diagnosing mesoinnominate shunt patency and detecting thrombosis, our study suggests that redundant screening methods can be avoided. Doppler US is accurate enough and should be the preferred technique in the evaluation of mesoinnominate shunts.
