“…10 This could be due to that the inferior vena cava (IVC) is a highly compliant vessel with no valves and its size varies with changes in intra vascular pressure, blood volume, right heart function and the degree of collapsibility during the respiratory cycle predicts the fluid status of the patient. 7,11,12 A study conducted by Ozdemir et al, in children with nephrotic syndrome found that there was no significant difference between the nephrotic syndrome patients (0.66±0.33) and controls (0.60±0.3) for IVCI (P >0.05). 13 The values for the IVCCI in the nephrotic patients (39.4±8.6) were much lower than the values calculated for the control subjects (56.9±8.7) (P <0.05).…”

Background: There is triad of hypoalbuminemia, edema, and hyperlipidemia in nephrotic syndrome patients. Management of nephrotic syndrome includes general measures like fluid restriction, emergency albumin transfusions and diuretics that provide symptomatic relief till steroids act. These measures require an assessment of body fluid volume to avoid circulatory failure which is very difficult in these patients because of edema. The objective of the study was to measure and compare the Inferior Vena Cava (IVC) Index and Inferior Vena Cava Collapsibility (IVCC) Index by ultrasound as a measure of body fluid volume status in children with nephrotic syndrome.Methods: The present observational study was conducted in all children of age more than 1 year up to 18 year. There were two groups; group 1 was nephrotic syndrome patients-Initial episode or in relapse and group 2 (Control) was age and sex-matched non-nephrotic children. IVC index and IVCC index were measured and compared in both the groups.Results: Mean value of minimum diameter of IVC during inspiration in cases was 5.91±1.60 mm as compared to 4.53±0.94 mm in controls which was significantly higher in case group {P ˂0.0001}. Mean value of IVC index in cases was 0.88±0.20 cm/m2 as compared to 0.93±0.19 cm/m2 in controls which was non-significant. Mean value of IVCC index in cases (35.61±13.68) was significantly less as compared to controls (52.23±2.01) {P ˂0.0001}.Conclusions: The present study concluded that IVCC index is better indicator of body fluid volume status in nephrotic patients as compare to IVC index.

“…In 1979, Natori et al . for the first time proved the correlation between the alterations in IVC diameter and right atrial blood pressure ( 15 ) . At present, the measurement of the inferior vena cava (IVC) and inferior vena cava collapsibility (IVCCI) are effectively used to determine the body fluid status of dialysis patients ( 14 , 16 ) .…”

“…The conducted studies demonstrated a significant correlation between weight and diameter of the aorta both in transverse and longitudinal views (correlation coefficient >0.7). The literature suggests that the measurements of the index may be used interchangeably with CVP which is currently considered the most accurate method in assessing the fluid status of patients ( 15 ) . The non-invasive character of sonography suggests its greater usefulness in daily clinical practice.…”

The assessment of the body fluid status is one the most challenging tasks in clinical practice. Although there are many methods to assess the body fluid status of patients, none of them is fully satisfactory in contemporary medical sciences. In the article below, we compare the results of measurements performed by experienced and inexperienced examiners based on the inferior vena cava/aorta diameter index in a sonographic hydration assessment. The study enrolled 50 young students at the age of 19–26 (the median age was 22.95) including 27 women and 23 men. The volunteers were examined in the supine position with GE Logiq 7 system and a convex transducer with the frequency of 2–5 MHz. The measurements were performed in the longitudinal and transverse planes by two inexperienced examiners – the authors of this paper, following a four-hour training conducted by an experienced sonographer. The longitudinal values of the inferior vena cava/aorta diameter index obtained in this study were similar to those found in the literature. The reference value for the inferior vena cava/aorta index determined by Kosiak et al., which constituted 1.2 ± 2 SD, for SD = 0.17, was similar to the values obtained by the authors of this paper which equaled 1.2286 ± 2 SD, for SD = 0.2. The article presented below proves that measuring the inferior vena cava/aorta diameter index is not a complex examination and it may be performed by physicians with no sonographic experience. Furthermore, the paper demonstrates that the inferior vena cava/aorta diameter index measured in the transverse plane is similar to the inferior vena cava/aorta diameter index determined in the longitudinal plane. Thus, both measurements may be used interchangeably to assess the hydration status of patients.

“…A modality which may offer the possibility of even more accurate assessment of the fluid status and enable monitoring of patients is sonography ( 4 , 5 ) . The ultrasound assessment of the diameter of the inferior vena cava and aorta (IVC/Ao index) with the ultrasound transducer placed in the anterior median line is a recognized method ( 6 , 7 ) used in the emergency departments and intensive care units. The limitations of this method include: trauma in the substernal region, wound dressing or substantial amount of gas in the intestines.…”

The aim of the study was to compare the values of the sonographic inferior vena cava/ aorta index obtained with the transducer placed in the median line and right anterior axillary line.Material and methodsThe study enrolled 45 volunteers, including 33 women, aged 22.5 ± 1.26 with a negative history of circulatory and renal diseases. The study consisted in a sonographic assessment and measurement of the inferior vena cava and aorta by placing the transducer in the anterior median line and right anterior axillary line. The value of the inferior vena cava/aorta index was obtained by calculating the ratio of the diameters of the inferior vena cava and aorta. The diameter measurements were taken by placing the ultrasound transducer in the anterior median line and right anterior axillary line. Two examiners performed the measurement three times and used convex probes of 3.5–5 MHz. Additionally, the subjects’ weight, height and arterial blood pressure were taken.ResultsFollowing a statistical analysis with the use of STATISTICA software, the following values of the inferior vena cava/aorta index were obtained: in the anterior median line – 1.43 ± 0.21, and in the right anterior axillary line – 1.285 ± 0.19. There was no statistically significant difference between the measurements obtained by the two examiners (p = 0.17). A strong correlation was noted between the inferior vena cava/ aorta indices calculated in both sites of transducer placement, which was irrespective of the examiners (the correlation coefficient: r = 0.61 and r = 0.71). The study indicate that the inferior vena cava/aorta index measured in the right anterior axillary line is a simple and reproducible method for determining the body fluid status; the examinations conducted in both sites may be used interchangeably. Further studies are needed to determine reference values for the inferior vena cava/aorta index measured in the right anterior axillary line.
