Application of conventional ultrasound and contrast-enhanced ultrasonography in comparison of the two different artery remodling techniques for kidney transplantation / 中华超声影像学杂志

ABSTRACT

ObjectiveTo assess long-term effect of two different types of arterial reanastomoses for kidney transplantation [an end-to-side anastomoses (ESA) of renal artery to external iliac artery and an endto-end anastomoses (EEA) of renal artery to internal iliac artery] by comparing conventional ultrasound and contrast-enhanced ultrasonography(CEUS) after five years of renal transplantation.MethodsSixty patients underwent kidney transplatation were included and divided into EEA group or ESA group based on the type of anastomoses. Data of renal blood flow perfusion,hemodynamic parameters,and renal anatomical structure were collected and analyzed in each groups using CEUS,color Doppler flow imaging(CDFI) and B-mode ultrasound.ResultsThe patients of the two arterial reanastomoses had no significantly difference in B-mode ultrasound and CDFI. The ESA patients had a slightly better perfusion than the EEA ones in parameters of CEUS.Conclusions Transplant tissue perfusion imaging was performed by CEUS. The perfusion of ESA grafts was slightly better than that of EEA.
