Can Ultrasound-Guided in-Plane Puncture Technique Enhance the Precision of Femoral Artery Access? The Randomized PARFEM Trial.

ABSTRACT:

Background

Ultrasound-guided puncture of the common femoral artery (CFA) is assumed to be more precise than conventional techniques without ultrasound. However, previous comparative studies have shown partly contradictory results with regard to success of ultrasound-guided puncture so that this method is not yet standard in transfemoral cardiac catheterization.

Aims

The PARFEM trial was performed to investigate whether an ultrasound-assisted in-plane technique using a needle guide could improve the precision of CFA puncture.

Methods

The study was conducted in 286 patients undergoing transfemoral cardiac catheterization. Patients were randomized 1:1, and femoral artery puncture was performed either using an ultrasound-guided in-plane technique with fluoroscopic marking
