The diameter of the inferior vena cava (IVC) measured with echocardiography is clinically used as a parameter to estimate right atrial pressure, which reflects dehydration or overhydration. Because elderly patients fall easily into dehydration, normal values for IVC diameters in elderly patients may be helpful for geriatric medicine. However, normal values of IVC diameter in relation to age hav...

BACKGROUND The inferior vena cava (IVC) parameters, including its diameter and collapsibility index have been evaluated for fluid status for over 30 years, but little is known about the impacts of patient characteristics on IVC parameters. The purpose of this study was to explore the relationships between individual patient characteristics and IVC parameters in healthy Chinese adult volunteers....

introduction: the correlation of central venous pressure (cvp) with inferior vena cava (ivc) sonographic diameter has been reported in several studies. however, few studies have attempted to find the best anatomic location of measurement. therefore, the purpose of this study was determining the best anatomic location to find precise correlation between cvp and ivc diameter using transesophageal...

introduction:the assessment of intravascular volume in severely traumatized patients or patients admitted in icu is very essential. at present the accurate method for estimating the intravascular volume requirement is by measuring the cvp which is an invasive method. the measurement of ivc diameter by ultrasound has been suggested as an easily available and simple method for measuring the intra...

INTRODUCTION The correlation of central venous pressure (CVP) with inferior vena cava (IVC) sonographic diameter has been reported in several studies.

The aim of the study was to explore the long- and short-axis dimensions, shape and collapsibility of the inferior vena cava in 46 trained and 48 untrained females (mean age: 21 ± 2 y). Echocardiography in the subcostal view revealed a larger expiratory long-axis diameter (mean: 24 ± 3 vs. 20 ± 3 mm, p < 0.001) and short-axis area (mean: 5.5 ± 1.5 vs. 4.7 ± 1.4 cm2, p = 0.014) in trained females...

Assessment of respirophasic diameter fluctuations of the inferior vena cava (IVC) is detrimentally affected by its concomitant displacements. This study aims at presenting and validating a method to compensate for IVC movement artifacts while continuously measuring its diameter in an automated fashion (with minimal interaction with the user) from a longitudinal B-mode ultrasound (US) clip. Perf...

BACKGROUND Central venous pressure (CVP) and right atrial pressure (RAP) are important parameters in the complete hemodynamic assessment of a patient. Sonographic measurement of the inferior vena cava (IVC) diameter is a non-invasive method of estimating these parameters, but there are limited data summarizing its diagnostic accuracy across multiple studies. We performed a comprehensive review ...

BACKGROUND  Right atrial pressure (RAP) is commonly estimated using inferior vena cava (IVC) diameter and its respirophasic variations. Although a guideline has been provided for estimation of RAP due to variation in IVC dimensions based on studies in Western subjects, echocardiographic values in Asian subjects are unknown. METHODS AND RESULTS  We studied 369 patients who underwent IVC ultras...
