Ultrasound guidance versus anatomical landmark approach for femoral artery access in coronary angiography: A randomized controlled trial and a meta‐analysis

Abstract

Our study did not show significant benefits for the use of US to guide arterial femoral access compared to the anatomical landmark approach, but pooled analysis of five randomized trials showed decreased rates of bleeding events and venipunctures, and improved first-pass success. The clinical impact of these findings is uncertain, and do not warrant a systematic use of US-guidance in this clinical setting.
