The preoperative application of MSCT and MSCTP in performing TIPS combined with gastric coronary vein embolization / 介入放射学杂志

ABSTRACT

Objective To evaluate the clinical application of preoperative multi-slice computed tomography (MSCT) and multi-slice computed tomography portography (MSCTP) in performing transjugular intrahepatic portosystemic stent shunt (TIPSS) combined with gastric coronary vein embolization (GCVE). Methods A total of 126 patients with cirrhosis complicated by upper gastrointestinal bleeding or massive ascites due to portal hypertension were enrolled in this study. The patients were arranged to receive TIPSS together with GCVE. Before the treatment, MSCT and MSCTP were performed in all patients. By using post-processing techniques, including maximum intensity projection (MIP), multiplanar reformation (MPR), volume rendering (VR) and surface shade display (SSD), the anatomy of liver was comprehensively evaluated. Results Both MSCT and MSCTP could clearly display morphologic changes of liver , the spatial relationship of the portal and hepatic veins , the degree and extent of portal collateral circulation , and the severity of ascites, which provided important anatomical information for preoperative evaluation of TIPSS and GCVE. Conclusion MSCT and MSCTP are non-invasive and reliable examinations for the diagnosis of cirrhosis with portal hypertension, it can further clarify the diagnosis and guide the performance of TIPSS and GCVE.
