Objective To investigate the value of three-dimensional contrast-enhanced ultrasound (3D-CEUS) in diagnosing the hepatic artery complications after liver transplantation.
Methods A total of 26 liver transplant donors or recipients suspected with hepatic artery complications were examined by color Doppler ultrasound, two-dimensional contrast-enhanced ultrasound (2D-CEUS) and 3D-CEUS. The successful reconstruction rates of 3D-CEUS and the three-dimensional image quality of reconstructed hepatic arteries were evaluated.
Results In the 26 patients, 21 hepatic arteries could be visualized with a successful reconstruction rate 81%. The three-dimensional images of hepatic arteries by 3D-CEUS were continuous. The coronal(Z-axle), fine or circuitous branches or tributaries could be visualized well. The segmental hepatic arteries origin could be determined and the spatial relationship of vessels could be visualized definitely.
Conclusions The 3D-CEUS images are intuitive, three-dimensional and clear, and have clinical application value in diagnosing of hepatic artery complications after liver transplantation.
