- Abstract
<bold>Aim: </bold>This study aimed to evaluate whether a quantitative contrast-enhanced ultrasonography (CEUS) study is feasible to diagnose middle hepatic venous occlusion after living donor liver transplantation (LDLT).<bold>Materials and Methods: </bold>From December 2018 to July 2019, the CEUS study on the first postoperative day had been conducted in patients who underwent LDLT. 46 patients were finally included in the study. To obtain CEUS parameters from time-intensity curves (TICs) on the hepaticparenchyma, the two regions of interests (ROIs) were located in the right hepatic vein (RHV) territory and middle hepatic vein (MHV) territory of the right hepatic graft. The measured CEUS parameters were wash-in slope (WIS), peak intensity (PI), time to peak (TTP), and area under the curve (AUC). The subjects were classified into the occlusion and non-occlusion groups. In each group, the parameters measured in the RHV and MHV territories were compared with paired-sample Student'st-tests.<bold>Results: </bold>Hepatic venous occlusion was diagnosed in 25 patients (54%). The WIS, TTP, and AUC of the MHV territory (2.95 dB/sec; 22.39 sec; 204.27 dB·sec, respectively) were significantly different from those of the RHV territory (2.16 dB/sec; 25.81 sec; 165.66 dB·sec; all p<0.05). There were no statistically significant differences in PI between the MHV and RHV territories (19.08 dB vs. 18.27 dB, respectively; p=0.259). In the non-occlusion group, there was no parameter which was significantly different between MHV and RHV territories (p>0.05).<bold>Conclusion: </bold>The parametric analysis of CEUS can helpdiagnose middle hepatic venous occlusion after LDLT.
