Volume overload in hemodialysis (HD) patients is a major risk factor for all-cause and cardiovascular mortalities, but accurate of volume status (VS) in HD patients is challenging. One method to measure VS is inferior vena cava (IVC) assessment using IVC diameter and IVC collapsibility index (IVCCI). Recent studies showed IVC diameter and IVCCI correlates with VS in patients on HD but some studies showed limitations. The aim of this study was to evaluate the use of IVC assessment in HD patients to measure VS.
This cross sectional observational cohort study who were under regular HD in the Nephrology Unit of Wahidin Sudirohusodo Hospital Makassar in the period from May to September 2025. Inclusion criteria were: age equal or greater than 18 years and hemodynamic stable for examination. Every patient was evaluated for IVC diameter before and after HD. Written consents were obtained from all participants, and the study was approved by the ethical committee of faculty of medicine of Hasanuddin University. Voluson P6 GE ultrasonography probe was used to measure IVC diameter. The probe was placed in the subxiphoid location while the patients were in the supine position. Measurement was made 2 cm caudal to the junction point of the hepatic veins and IVC. We measured both the inspiratory and expiratory diameters by measuring IVC lumen from one interior wall to the opposite interior wall during a single respiratory cycle. IVC diameter was measured before and after HD. The IVCCI was calculated by the following equation: (IVC expiratory diameter – IVC inspiratory diameter)/IVC expiratory diameter × 100%. The statistical analysis was performed using Statistical Package for Social Sciences (SPSS) version 25.0.
Totally, 27 subjects were enrolled in this study are 19 (70.4%) are female, 20 (74.1%) with Hypertension and 9 (33.3%) with diabetes mellitus. Their anthropometric and clinical characteristics are shown in Table 1.
There was a significant correlation between IVC inspiratory diameter pre-HD and post-HD (1.38 ± 0.35 vs 1.48 ± 0.36, p= 0.000, R 0.79), IVC expiratory diameter pre-HD and post-HD (1.85 ± 0.37 vs 1.77 ± 0.32, p= 0.001, R 0.592), and as well as between IVCCI pre-HD and post-HD (25.33 ± 10.76 vs 17.08 ± 8.9, p= 0.000, R 0.704). Correlation between IVC diameters and IVCCI pre-HD and Post-HD are shown in Table 2.
IVC assessment using IVC diameter and IVCCI reliably indicate VS in HD patients.
