BACKGROUND: Individuals with chronic kidney disease (CKD) have twice the risk of peripheral arterial disease (PAD) and are more susceptible to arterial calcification. Diagnosing arterial abnormalities involves a combination of clinical assessment and noninvasive tests. The ankle-brachial index (ABI) is a cost-effective method for assessing arterial abnormalities and predicting mortality. Continuous Doppler ultrasound is the gold standard for ABI assessment due to its greater accuracy, and point-of-care ultrasound (POCUS) enables bedside measurement of this index.
OBJECTIVES: To analyze the prevalence of arterial abnormalities in individuals undergoing hemodialysis using POCUS.
METHODS: We conducted an observational, analytical, cross-sectional study of 85 patients on hemodialysis, using a clinical and sociodemographic questionnaire and calculating the ABI. The primary outcome was the analysis of the presence of arterial abnormalities through the measurement of ABI using the POCUS method..
RESULTS: The prevalence of ABI results suggestive of PAD and arterial calcification was 24.7% and 22.4%, respectively. Diabetes mellitus (p = 0.02) and advanced age (p = 0.01) were identified as the main risk factors for PAD.
CONCLUSIONS: The POCUS-assisted assessment identified a prevalence of 24.7% for PAD and 22.4% for arterial calcification among patients with CKD. Advanced age and diabetes mellitus were the main risk factors associated with PAD. The data suggest that POCUS is an innovative approach for the bedside diagnosis of arterial abnormalities in patients on hemodialysis.
