Introduction: Central vein puncture is a medical procedure traditionally done following anatomical landmarks as a reference to successfully achieving the vessel. However, this traditional technique is commonly unsuccessful due to anatomical variations that may be found. Point of care ultrasonography (POC-US) is used to assist central catheterization by directly visualizing the vessel, increasing procedure security and minimizing risks. Objectives: Evaluate anatomical variations prevalence in femoral vessels, utilizing POC-US, done by medical students submitted to a short period of time training in ultrasonography. Methods: Five medical students, without previous experience on the use of ultrasonography, were submitted to an eight-hour theorical practical training in POC-US. The students evaluated one hundred femoral vessels of volunteers. Results: The right limb femoral vein was found more frequently in the medial position (43%) in comparison to the right limb femoral artery. On the left limb, the posteromedial position was the most found (45%). Conclusion: The insertion of a central catheter following the traditional technique is based on anatomical landmarks, and does not take into account existing anatomical variations. With a short period of training, POC-US is capable of qualifying professionals to acknowledge the real location of the vessel and avoid inadvertent punctures and complications.
