Standard Versus Ultrasound-Guided Cannulation of the Femoral Artery in Patients Undergoing Invasive Procedures: A Meta-Analysis of Randomized Controlled Trials.

This study, which included all available data to date, demonstrated that, compared to a standard approach, ultrasound-guided cannulation of the femoral artery is associated with lower access-related complications and higher efficacy rates. These results could be of great clinical relevance especially in the femoral cannulation of high risk patients.
