简介/目标：在右侧心脏功能受损的人中，尾腔静脉 (CVC) 直径可作为静脉充血的标志。本研究旨在调查超声检查 CVC 变量是否可以识别患有右侧心脏病 (RHD) 的狗是否存在右侧充血性心力衰竭 (R-CHF)。 动物：纳入了 50 只客户拥有的对照狗和 67 只患有 RHD 的狗。患有 RHD 的狗被分为非 R-CHF (n = 43) 和 R-CHF (n = 24) 组。 材料和方法：我们测量并比较了各组之间的超声 CVC 变量和超声心动图变量。进行受试者工作特征（ROC）曲线分析，以计算最佳截断值下变量的敏感性和特异性。结果：我们获得了吸气期间最小CVC面积的最短直径（SD）与主动脉直径（Ao）的比值[SD（min）/Ao]和吸气期间SD（min）与最小CVC面积的最长直径比值[LD（min），SD/LD（min）]的最高准确度，具有较高的准确性。敏感性、特异性和 ROC 曲线下面积大于 0.925。结论：除了超声心动图评估右侧心功能外，本研究中的 CVC 变量，特别是 SD(min)/Ao 和 SD/LD(min)，将是识别 RHD 犬 R-CHF 的有用诊断指标。(c)& nbsp;2021 Elsevier B.V. 保留所有权利。
Introduction/objectives: In humans with impaired right-sided cardiac function, the caudal vena cava (CVC) diameter serves as a marker of venous conges-tion. This study aimed to investigate whether ultrasonographic CVC variables could identify the presence of right-sided congestive heart failure (R-CHF) in dogs with right-sided heart disease (RHD).Animals: Fifty client-owned control dogs and 67 dogs with RHD were enrolled. The dogs with RHD were subdivided into the non-R-CHF (n = 43) and R-CHF (n = 24) groups.Materials and methods: We measured and compared the ultrasonographic CVC vari-ables and echocardiographic variables among the groups. Receiver operating characteristic (ROC) curve analysis was performed to calculate the sensitivity and specificity of the variables at optimal cutoff values.Results: We obtained the highest accuracies of the ratio of the shortest diameter (SD) of the minimal CVC area to the aorta diameter (Ao) during inspiration [SD(min)/Ao] and of the ratio of SD(min) to the longest diameter of the minimal CVC area during inspiration [LD(min),SD/LD(min)], with high sensitivities, specificities, and an area under the ROC curve greater than 0.925.Conclusions: In addition to the echocardiographic assessment of right-sided cardiac function, the CVC variables in this study, especially SD(min)/Ao and SD/LD(min), would be useful diagnostic indices for identifying R-CHF in dogs with RHD.(c)& nbsp;2021 Elsevier B.V.
