Nine patients who had undergone end-to-side portocaval shunts were assessed using a sector real-time color Doppler sonography system. Shunt patency was demonstrated in 8 of 9 patients by detection of color-coded flow within the portal vein, in the anastomotic region, and in the inferior vena cava adjacent to the shunt. Color flow could not be detected in 1 patient. This patient had no evidence of shunt compromise. Spectral Doppler studies were also performed in these patients and flow was demonstrated in all 8. In these instances, information available with color Doppler imaging allowed visualization of the shunt even when it had not been apparent on preliminary real-time grey-scale imaging. This study, which does not assess accuracy, nevertheless suggests that color flow Doppler sonography may prove useful in assessing patients with portocaval shunts.
使用扇形实时彩色多普勒超声系统对9例行端侧门腔分流术的患者进行了评估。通过检测门静脉内、吻合区域以及分流附近下腔静脉内的彩色编码血流，9例患者中有8例显示分流通畅。1例患者未检测到彩色血流。该患者无分流受损的证据。还对这些患者进行了频谱多普勒研究，所有8例均显示有血流。在这些情况下，即使在初步实时灰阶成像中分流不明显，彩色多普勒成像所提供的信息也能使分流可视化。本研究虽未评估准确性，但提示彩色血流多普勒超声可能对评估门腔分流患者有用。
