急性排异反应(AR)是肾移植术后早期最常见的并发症,也是导致移植肾功能丧失的主要原因,其病理改变可引起移植肾血流灌注的变化,此为国内外研究的热点。超声是监测肾移植术后AR的重要方法,可提供移植肾解剖、血流等信息,其中超声造影在评价移植肾微循环灌注方面具有非常重要的作用,有望使移植肾AR的检测从定性、半定量水平发展到定量水平,提高超声检查的特异性和敏感性。
Acute rejection (AR) is the most common complication in the early stage of renal transplantation, which is also the main reason leading to the loss of renal function. The pathological changes can cause the changes of perfusion of transplanted kidneys. This is a hot topic at home and abroad. Ultrasound is an important method to monitor AR after renal transplantation, which can provide anatomical information such as anatomic and blood flow of the renal transplant. Ultrasound is very important in assessing microcirculation perfusion of renal allograft, Semi-quantitative levels of development to the quantitative level, improve the specificity and sensitivity of ultrasound.
