Vascular access is the process of gaining entry into a blood vessel, either an artery or vein, for purposes such as administering medications, drawing blood, placing catheters, or performing dialysis. Ultrasound guidance has transformed vascular access by allowing clinicians to visualize the target vessel, surrounding structures, and the needle in real time during the procedure. This significantly reduces complications such as arterial puncture, hematoma, pneumothorax (when accessing central veins near the lung), and multiple failed attempts. Common ultrasound-guided vascular access procedures include peripheral IV placement, central venous catheter insertion (internal jugular, subclavian, femoral veins), arterial line placement, and dialysis access evaluation. The ability to assess vessel size, patency, and depth before needle insertion has made ultrasound-guided vascular access a standard of care in many clinical settings.
