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

Abstract

The prevalence of LOP requiring treatment is 4.7% when UGFAA is used during pediatric cardiac catheterizations. Arterial spasm was more common than thrombus as a cause of LOP. FA diameter <3 mm was the only independent predictor for LOP in this carefully designed prospective study. © 2016 Wiley Periodicals, Inc.
