Usefulness of artery femoral ultrasound complementary to carotid exploration for the detection of subclinical atheromatosis in patients with human immunodeficiency virus infection

Abstract

Introduction: Detection of subclinical atheromatosis disease (SAD) in patients with human immunodeficiency virus (HIV) infection is usually based on carotid ultrasound. However, studies in other pathologies have shown a probable underestimation of SAD when its detection is exclusively based on carotid exploration. This study evaluates the impact on detection of SAD in patients with HIV through combined carotid and femoral exploration.

Methods: Cross-sectional and prospective study of patients with HIV, diagnosed between 2008-2017. Carotid and femoral ultrasound examination was performed in all patients. EAS was defined according to Mannheim criteria.

Results: One hundred two patients were included (mean age: 40 years, 73.5% being male). The prevalence of carotid SAD in the total sample was 15.7% (n=16), and the prevalence of femoral SAD was 18.6% (n=19). The proportion of patients with global SAD criteria (carotid or femoral) was 23.5% (n=24), which implies an absolute increase in SAD detection of 7.84% (95% CI; 2.63-13.06%) at the total sample.

Conclusions: Detection of SAD is significantly increased by the combined use of carotid and femoral arterial ultrasound in the population affected by HIV infection.
