Abstract:
Femoral arterial access is fundamental to interventional cardiology, especially for complex procedures that require large-bore devices. However, vascular complications arising from suboptimal puncture techniques highlight the need for meticulous practice. This article presents a systematic, ultrasound-guided approach for achieving an optimal common femoral artery (CFA) puncture, defined by five key criteria: access within the CFA, anterior wall-only penetration, centralized lumen entry, puncture above the femoral head, and entry into a healthy arterial segment. We detail a six-step protocol incorporating ultrasound guidance throughout: (1) identification of the CFA and femoral vein; (2) delineation of CFA boundaries; (3) localization of the femoral head; (4) determination of the optimal puncture site; (5) real-time needle tracking and precise CFA puncture; and (6) confirmation of correct guidewire insertion. This protocol enhances both the safety and reproducibility of the procedure. Although there is a significant learning curve, proficiency with this method aims to enable rapid, consistent, and low-complication vascular access. The article offers practical recommendations for implementation in the catheterization laboratory-including equipment selection and team training-and reviews current literature supporting the efficacy of ultrasound in minimizing access-related complications.
