用多普勒超声检查了10只健康成年比格犬、20只健康幼犬（13只猎鹿犬和7只爱尔兰猎狼犬）和7只先天性或后天性肝病犬的肝总动脉，记录了收缩期峰值流速（V-s）、阻力指数（RI）、脉率、声入角和样本体积深度。Beagle犬禁食24 h后测定V-s和RI，禁食后2 h重复测定，V-s和RI的平均值分别为1.5 m/s（范围1.1-2.3 m/s）和0.68（范围0.62-0.74）。餐后，这些变量均无显著差异。幼仔的平均V-s和RI较低：1.0米/秒（范围0.8-1.3 m/s）和0.59（范围0.46-0.65）2只先天性动静脉瘘犬的平均V-s明显高于对照组（P <0.001）（P < .001）和较低的平均RI在正常比格犬、门静脉血栓形成犬、和两只后天性肝功能不全的狗不同年龄或品种犬的肝血流量测量值的差异将使肝动脉多普勒测量的诊断应用复杂化。
The common hepatic artery in 10 healthy adult beagles, 20 healthy pups (13 Deerhounds and seven Irish Wolfhounds), and seven dogs with either a congenital or acquired hepatic disorder was examined by duplex-Doppler ultrasonography, Peak systolic velocity (V-s), resistive index (RI), pulse rate, angle of insonation, and sample volume depth were recorded. Measurements in Beagles were made after a 24 h fast and repeated 2 h after feeding, The mean V-s and RI in fasted Beagles were 1.5 m/s (range 1.1-2.3 m/s) and 0.68 (range 0.62-0.74), respectively. Postprandially, there were no significant differences in any of these variables. Mean V-s and RI were lower in pups: 1.0 m/s (range 0.8-1.3 m/s) and 0.59 (range 0.46-0.65), respectively (P < .001), Two dogs with congenital arterioportal fistula had higher mean V-s (P < .001) and lower mean RI (P < .05) than normal pups, No significant differences were detected between normal Beagles, three dogs with portal vein thrombosis, and two dogs with acquired hepatic insufficiency. Differences in measured hepatic blood flow in dogs of different age or breed will complicate diagnostic use of hepatic arterial Doppler measurements.
