CEUS: A new imaging approach for postoperative vascular complications after right-lobe LDLT

Figure 4 Regional congestion in a 35-year-old man who underwent RLDLT. A: Longitudinal oblique 2D US scan 1 d after RLDLT revealed regional echogenicity in segment V; B: Contrast-enhanced CT showed poor perfusion (arrow) in segment V 2 d after ultrasound examination; C: Longitudinal oblique 2D US scan revealed regional echogenicity in segment VII; D: Contrast-enhanced CT showed poor perfusion (arrow) in segment VII; E: Longitudinal oblique CEUS scan obtained following the Doppler scan. At CEUS, the poor perfusion area (arrows) was seen as an inhomogenous echo that corresponded to segment V and segment VII. This patient remained asymptomatic and formed collaterals between the tributary of the middle hepatic vein and the right hepatic vein at Doppler ultrasound follow-up.
