Ultrasound-guided vs. Non-ultrasound-guided femoral artery puncture techniques: a comprehensive systematic review and meta-analysis

This meta-analysis suggests potential benefits of US femoral artery puncture techniques over non-US methods, while acknowledging significant heterogeneity across studies. The observed advantages in procedural outcomes varied across different clinical settings and operator experience levels. These findings provide setting for institutional decision-making regarding the implementation of guided puncture methods, considering factors such as operator expertise, resource availability, and specific patient populations.
