Duplex spectral or color Doppler sonography demonstrated major abdominal vessel blocks affecting 18 vessels in 16 infants aged between 23 and 56 weeks postconceptional age. The portal vein was affected in 8 infants, the renal vein in 3, the renal vein and inferior vena cava in 1, the renal artery in 1, the inferior vena cava and hepatic vein in 1, and the aorta in 2 infants. Doppler sonography confirmed the grey-scale findings and often demonstrated the extent of vascular flow, providing functional information not available from the grey-scale scan. It facilitated the follow-up of thrombosis during therapy. Most important of all, in many instances it enabled a rapid and reliable specific diagnosis often not possible on the grey-scale study alone and hence altered patient management.
双功频谱或彩色多普勒超声检查显示，在16名孕龄23至56周的婴儿中，主要腹部血管阻塞影响了18条血管。8名婴儿的门静脉受影响，3名婴儿的肾静脉受影响，1名婴儿的肾静脉和下腔静脉受影响，1名婴儿的肾动脉受影响，1名婴儿的下腔静脉和肝静脉受影响，2名婴儿的主动脉受影响。多普勒超声检查证实了灰阶检查结果，并常常显示血管血流的范围，提供了灰阶扫描无法获得的功能信息。它有助于在治疗期间对血栓形成进行随访。最重要的是，在许多情况下，它能够做出快速可靠的特异性诊断，而这通常仅靠灰阶检查是无法做到的，因此改变了患者的治疗方案。
