Obesity Hinders Ultrasound Visualization of the Subclavian Vein: Implications for Central Venous Access

Abstract

Higher BMI and the presence of a flat clavicle limit the ability to visualize the SCV. These findings may help account for why USG for placement of SCV CVCs is less utilized. However, patients with a low/normal BMI and protuberant clavicle may benefit from USG when attempting SCV CVCs.
