“…Ultrasonography of the CVC visualized between the 9th and the 12th intercostal space in HF calves demonstrated that the circumference of the CVC increases with age [ 21 ]. Studies performed on healthy children also showed a positive correlation between age and IVC and Ao diameter, and, inconsistently, with the IVC and Ao index [ 25 , 26 , 27 , 28 ]. Del Prete et al (2021) showed a correlation between age and the long axis of CVC and the CVC and Ao diameter index [ 19 ].…”

Ultrasonographic measurements of the caudal vena cava (CVC) and aorta (Ao) are known as reliable tools to assess intravascular volume status in humans. The aim of this study was to evaluate the feasibility of obtaining ultrasonographical measurements of CVC and Ao in two different views, assess intra- and interobserver variability, and study the effect of sex, age, body weight, and breed on measurements in healthy calves. The diameter and area of CVC and Ao were measured by a single investigator in two anatomic sites (subxiphoid and paralumbar window) in 48 calves aged less than 60 days and then repeated 2.5 months after the first assessment. For intra- and interobserver variability assessment, CVC and Ao measurements were repeated by three observers on five randomly selected calves. CVC and Ao measurements were easily obtained in PV and more difficult to obtain in SV. CVC and Ao area in PV showed high repeatability and reproducibility. A positive correlation was highlighted between age and CVC and Ao measurements in both sites. In conclusion, CVC size assessment by point of care ultrasound can be easily performed at a paralumbar site in calves under 4 months of age and could be used to assess intravascular volume status.

“…In veterinary medicine, several studies evaluating circulatory dynamics using CVC/Ao by ultrasonography have been reported [ 17 , 25 ]. In human medicine, imaging studies have shown that evaluation methods based on the long diameter/short diameter ratio of the IVC and the IVC/aorta ratio are less affected by body size [ 14 , 35 ]. This suggests that these methods may be applicable to animals, but no useful index for evaluating CVC size on CT images in dogs has been proposed.…”

This study investigated the association between caudal vena cava (CVC) size and circulatory dynamics in dogs using computed tomography (CT) under general anesthesia. The subjects were 104 dogs who had undergone CT under general anesthesia in the past. The ratio of short diameter of the CVC to aortic diameter (CVCS/Ao) and the ratio of long to short diameter of the CVC (CVCL/CVCS) in the thorax and abdomen, respectively, were calculated using factors such as mean blood pressure (MBP), shock index (SI), anemia, hypoproteinemia, presence of intra-abdominal mass, and cardiac disease. There was a significant but negligible negative correlation between CVCS/Ao and MBP. In contrast, no significant correlation was found between CVC size and SI. The low MBP group had significantly higher CVCS/Ao of the thorax than the normal MBP group. The group with intraabdominal mass had significantly lower CVCS/Ao of the abdomen than the group without intraabdominal mass. The group with cardiac disease had significantly lower CVCL/CVCS of the thorax 4 than the group without cardiac disease. In multiple regression analysis, low MBP, cardiac disease, intra-abdominal mass, and anemia were significant factors for CVCS/Ao of the thorax, CVCL/CVCS of the thorax, CVCS/Ao of the abdomen, and CVCL/CVCS of the abdomen, respectively. In conclusion, CVC size assessment using CT in dogs under general anesthesia is influenced by various factors.

“…This analysis found that the use of the IVC/Ao with a reference value of 0.68-1.4 was useful for defining pediatric volumetric status. 29 In one of the analyzed studies, Babaie et al reported a sensitivity of only 50.8% and specificity of 87.5% for predicting pediatric hypovolemic states. Furthermore, the IVC/Ao had superior ability to IVCci for predicting hypovolemia in children under spontaneous ventilation.…”

Background: The assessment of intravascular volume and fluid responsiveness is challenging in the management of critically ill patients. Diagnostic methods of hemodynamic monitoring must be safe, reproducible, and practical. Objective: To describe the applicability of ultrasound indices of the inferior vena cava in the assessment of intravascular volume and prediction of fluid responsiveness in critically ill patients. Method: A systematic review performed of the PubMed®, Latin American and Caribbean Health Sciences Literature, and Scientific Electronic Library Online databases for articles published in the previous five years. The descriptors used were “inferior vena cava,” “ultrasonography,” “fluid responsiveness,” and “volume status.” Results: The search identified 13 relevant articles. The collapsibility index of the inferior vena cava was 25%–50% as the cutoff point for defining hypovolemia and showed applicability in predicting fluid responsiveness in patients breathing spontaneously with cutoff points of 25%–57%. In mechanical ventilation scenarios, the distensibility index of the inferior vena cava was more effective at predicting fluid responsiveness than the other measurements with variation of 10.2%–20.5%. The inferior vena cava/aorta diameter index was especially useful in the pediatric population for defining intravascular volume; however, in adults, there were many divergences in its applicability. Conclusion: The assessment of intravascular volume and fluid responsiveness through ultrasound indices of the inferior vena cava is applicable and safe for diagnosing and monitoring hemodynamic instability. However, studies of value standardization are necessary due to divergences in the cutoff points used in each index.
