Tumor-feeding artery diameter reduction is associated with improved short-term effect of hepatic arterial infusion chemotherapy plus lenvatinib treatment

Figure 2 Shrinkage of the hepatic artery diameters in patient with unresectable hepatocellular carcinoma after treatment with hepatic arterial infusion chemotherapy plus lenvatinib. A-C: Digital subtraction angiography performed before treatment (A), after 1 (B) and 2 (C) mo of treatment; D-H: Bars represent the vessel diameters before treatment, at 1 and 2 mo after treatment. P-values are calculated using the mixed linear model for repeated measured data. ^cP < 0.001. NS: Not significant (P > 0.05); CHA: Common hepatic artery; PHA: Proper hepatic artery; LHA: Left hepatic artery; RHA: Right hepatic artery; TFA: Tumor-feeding artery.
