PDFAbstract
Objective To investigate the value of CT combined with enhanced scan in the diagnosis of portal vein tumor thrombus in the right liver with Ca. Methods Retrospectively analyze CT angiography data and clinical data of 31 patients from March 2014 to May 2016. Results Among 31 patients, there are 8 cases of the type Ⅰ, 7 cases of type Ⅱ, 11cases of type Ⅲ, and 5cases of type Ⅳ. There are 29 cases of equal density thrombus, 2 cases of slightly low density thrombus, the diameter of portal vein is about 1.5cm - 3.4cm and an average of (2.3±0.51)cm. There are 21 cases of slightly enhancement thrombus and 5 cases of reinforced walls in the enhanced scan artery phase. There are 23 cases of low-density filling defects in the CT enhanced venous phase. Conclusion The specificity of the diagnosis of portal vein tumor thrombus in the right liver with Ca is 100%. It not only determines the precise period of thrombus, the size, location and other parameters of tumor thrombus, but also is able to be non-invasive and convenient, which is worthy of further promotion and application.
