The mesoatrial shunt is performed in patients with the Budd-Chiari syndrome when the inferior vena cava is occluded and not available for a conventional portosystemic shunt. Computed tomography (CT), with injection of contrast media, was used to evaluate mesoatrial shunt patency with five examinations in four patients. Shunt patency was demonstrated by CT and confirmed by angiography in two studies. Total shunt occlusion diagnosed by CT in two additional cases was confirmed by angiography or operation. Partial graft occlusion diagnosed by CT in a fifth study was verified by both angiography and operation. CT is recommended instead of angiography in the evaluation of mesoatrial shunts because it is less invasive, it may be performed on an outpatient basis, and it yields additional useful information related to shunt patency, such as the volume of ascites, collateral vascularity, and the size of the spleen.
当布加综合征患者的下腔静脉闭塞且无法进行传统的门体分流术时，可进行中房分流术。对4例患者进行了5次检查，通过注射造影剂的计算机断层扫描（CT）来评估中房分流术的通畅情况。在两项研究中，CT显示分流通畅并经血管造影证实。另外两例经CT诊断的分流完全闭塞经血管造影或手术证实。在第五项研究中经CT诊断的移植物部分闭塞经血管造影和手术均得到证实。在评估中房分流时，推荐使用CT而非血管造影，因为CT侵入性较小，可在门诊进行，并且能提供与分流通畅相关的其他有用信息，如腹水量、侧支血管情况和脾脏大小。
