Abstract
Objective To study the application of multiple row spiral CT (MSCT) in the diagnosis of inferior vena cava lesions in Budd Chiari syndrome (BCS) and its clinical value. Methods Eighty patients with BCS admitted to the Central Hospital of Shan County from May 2017 to May 2018 were divided into two groups by digital grouping method, with 40 cases in each group.The control group was diagnosed by ultrasound, and the study group was diagnosed by multi-slice CT.The pathological changes, tissue contrast of inferior vena cava and hepatic vein and the diagnostic sensitivity, specificity, positive predictive value and negative predictive value of inferior vena cava obstruction were compared between the two groups. Results The pathological diagnosis rate in the study group was significantly higher than that in the control group(χ2=4.562, 4.695, 4.125, 5.124, all P<0.05). The contrast of inferior vena cava and hepatic vein tissues in the study group was significantly higher than that in the control group (t=12.897, 13.214, all P<0.05). The sensitivity, specificity, positive predictive value and negative predictive value of the diagnosis of inferior vena cava occlusion in the study group were higher than those in the control group (the control group: 91.2%, 98.6%, 97.3%, 80.3%, the study group: 100.0%, 99.5%, 98.2%, 100.0%, χ2=11.897, 10.214, 11.235, 13.564, all P<0.05). Conclusion The application of MSCT in the diagnosis of BCS-inferior vena cava lesions, can display the lesions comprehensively and intuitive guidance in the treatment of inferior vena cava lesions, has high diagnostic value, it is worthy of popularization and application in clinic.
