In patients with liver cirrhosis Doppler ultrasound often detects absence of the retrograde (hepatopetal) flow phase in the hepatic vein, suggestive of an increased stiffness of the liver parenchyma around the vein. This is rarely or never reported in healthy control persons. We examined the frequency of absent retrograde flow in a consecutive series of 139 patients referred for abdominal ultrasound. We used state-of-the-art ultrasound scanners, and placed the Doppler gate so that in non-forced end-expiration it would sample the right hepatic vein 4-6 cm from the vena cava. There was no association between the hepatic vein flow pattern and age, sex or body mass index. 43 of 139 studied patients showed absent retrograde flow. Review of the case records revealed liver disease in 26 patients and no sign of liver disease in 17 patients. We suggest that absent retrograde flow in the hepatic veins may be seen not only in patients with overt liver disease but also in apparently liver-healthy patients.
在肝硬化患者中，多普勒超声常常检测到肝静脉逆行（向肝）血流期缺失，提示静脉周围肝实质硬度增加。在健康对照人群中，这种情况很少或从未被报道过。我们检查了连续139例因腹部超声前来就诊患者中逆行血流缺失的频率。我们使用了最先进的超声扫描仪，并放置多普勒取样容积，以便在非用力呼气时，对距腔静脉4 - 6厘米处的右肝静脉进行取样。肝静脉血流模式与年龄、性别或体重指数之间无关联。139例研究患者中有43例显示逆行血流缺失。查阅病例记录发现，26例患者有肝脏疾病，17例患者无肝脏疾病迹象。我们认为，肝静脉逆行血流缺失不仅可见于有明显肝脏疾病的患者，也可见于表面上肝脏健康的患者。
