ABSTRACT

Objective To study preliminarily on the value of real-time three-dimensional contrast-enhanced ultrasound (RT-3D-CEUS ) for the diagnosis of hepatic artery complications after liver transplantation.Methods From April to July in 201 4,a total of 1 8 liver transplant recipients were examined 29 times,by color doppler ultrasound,contrast-enhanced ultrasound (2D-CEUS)and RT-3D-CEUS.The successful rate of RT-3D-CEUS was calculated.And the image quality and the diagnosis of hepatic artery complications were evaluated.Results In the 29 times of RT-3D-CEUS examination,the successful rate was 93% (27 /29).The image quality of RT-3D-CEUS got 3 points for 1 4 times,2 points for 1 3 times and 1 point for 2 times.In 6 cases who were diagnosed hepatic artery stenosis by RT-3D-CEUS,4 cases were first diagnosed by RT-3D-CEUS and confirmed by CTA,and 2 cases were diagnosed by CTA or DSA before RT-3D-CEUS.Conclusions The RT-3D-CEUS examination can get intuitive and clear images,which has clinical application value in evaluating hepatic artery complications after liver transplantation.
