Abstract

Purpose: The objectives of our study were to evaluate the changes in the cross-section area of carotid and femoral arteries caused by fluid loss during haemodialysis (HD) and to determine the direction and amount of these changes.

Material and methods: Seventy-four HD patients (28 women and 46 men) were studied. We performed ultrasound exams of the distal common carotid and proximal femoral arteries in each patient before and after a HD session. Recorded exams were analysed using EchoPac software. Arterial cross-section area values were acquired for further analysis.

Results: We found a statistically significant decrease in arterial systolic cross-section area values after HD sessions (carotid arteries area before HD equalled 0.6731 cm2 and 0.6333 cm2, p = 0.00001 after HD, femoral arteries area before HD equalled 0.8263 cm2 and 0.7635 cm2, p = 0.00001 after HD). The decrease of systolic carotid cross-section area correlated with the amount of fluid lost during HD sessions (correlation coefficient of 0.3122, p = 0.010) and the percentage of the body mass lost during HD (correlation coefficient of 0.3577, p = 0.003). No statistically significant changes were found in the femoral cross-section area.

Conclusions: Our findings suggest that the arterial cross-section area may be used in the assessment of response to body fluid loss. We were able to measure changes due to fluid loss during the HD session. The carotid cross-section values decreased after the procedure and correlated with the amount of fluid lost during the HD session.
