Contrast-enhanced CT reveals inhomogeneous enhancement of liver, such as peripheral regions with low attenuation due to portal hypoperfusion and focal enhancing area owning to arterioportal shunting. Benign regenerative nodules, intrahepatic collateral circulation, body collateral circulation and hepatic cirrhosis can be seen in chronic BCS cases. Hepatocellular carcinoma often develops in chronic end-stage liver disease, sometimes it will be shown in BCS cases. Knowledge of the morphologic type of BCS is useful for guiding the therapeutic Senegenin approach and assessing operation risk. Shunt surgery is no longer the standard care for BCS, with advances in radiological interventions and a good midterm outcome. Interventional techniques can aid in treating and stabilising the patient for possible orthotopic liver transplantation when liver dysfunction progressive.. Percutaneous transluminal angioplasty can be used for patients with post-hepatic IVC membranous-type obstruction, balloon dilatation and percutaneous stent placement have been found to be the techniques for those with segmental IVC obstruction or IVC web. PTA is seldom adopted in Western countries, however, and stenting are effective and safe for treating BCS, with a good long-term outcome, because most chronic BCS are caused by membranous obstruction. According to our experiences, large balloon dilation with a diameter of 25�C 30 mm Saikosaponin-C ballon catheter is safe and effective for most IVC obstruction cases, and only few cases need further stenting after large balloon dilation. The blood backflow of HV and liver function can be basically compensated, as long as there was a widely patent HV, regardless of which branch of the main HVs was or whether it was the accessory HV. PTA, mainly balloon dilation, is suitable for this kind of BCS. TIPS and orthotopic liver transplantation are usually adopted in Western countries, although the survival rate is poor.. In case of short segment occlusion or stenosis of HV and/or IVC, the obstruction between remnant HV and IVC should be reopened by means of balloon angioplasty with or without stent placement. TIPS and surgical options are reserved for patients with failure of interventions due to complete occlusion of HV. Patients with both the and segmental IVC occlusion require opening of both occlusive segments, these may be difficult and challenging and the several multiple approaches should be required. The IVC occlusion should be reopened as long as they have unobstructed HV blood flow. Besides, additional therapies with anticoagulation, pharmacological or endoscopic treatment for variceal bleeding and diuretics for ascites should be considered.. In this context, computer-aided texture analysis can be a promising method for lesion characterization. Texture analysis is an imaging analysis method that assesses and quantifies lesion characteristics using pixel values and/or their distribution within target lesions, providing a more detailed and reproducible quantitative assessment of lesion characteristics than visual analysis by human observers. Indeed, several texture features such as skewness, kurtosis, entropy, or uniformity have already been reported to be clinically applicable and valuable 
in the diagnosis of malignancy, treatment monitoring, and prediction of patients’ prognosis. In addition, Goh et al. reported that CT texture analysis reflecting tumor heterogeneity is an independent factor associated with time to progression and has the potential to be a predictive imaging biomarker of the response of metastatic renal cancer to targeted therapy.
