Macrovascular Malignant Portal Vein Thrombosis in Cirrhotic Patients with HCC

Methods: The diagnosis of HCC in cirrhotic patients was based on the EASL guidelines. On contrast-enhanced CT scans, MMPVT was identified by the presence of a low-attenuation intra-luminal filling defect. Intrathrombus vascularity, observed in the arterial phase of imaging studies after the administration of contrast, has been reported to be a sign that is specific for MMPVT on CT [3]. MMPVT was graded into 4 grades according to Nonami grading [3]. Child-TurcottePuph (CTP) score was calculated for every patient and AFP was measured. Neutrophillymphocyte ratio (NLR) was calculated by dividing the neutrophil count by the lymphocyte count, provided that there was no ongoing infection.
