Ultrasound‐guided femoral arterial access in pediatric cardiac catheterizations: A prospective evaluation of the prevalence, risk factors, and mechanism for acute loss of arterial pulse

Objectives The objectives of this study were to describe the prevalence, mechanisms, and identify risk factors for acute loss of arterial pulse (LOP) in children who had ultrasound‐guided femoral arterial access (UGFAA) during cardiac catheterization. Background LOP is a known complication in children following femoral arterial (FA) access for cardiac catheterization. The prevalence of LOP requiring treatment ranges between 4% and 8%. Methods A...
