Central venous catheter placement with ultrasound guidance improves the success rate and reduces the number of puncture attempts and complications. Y-shape visualization of central veins using an endocavity micro-convex ultrasound probe is a new technique, which has been used for brachiocephalic vein cannulation. Since the jugular, subclavian, and brachiocephalic veins can be visualized in a single view using the Y-shape technique, it can also be used to confirm the correct placement of the catheter or guidewire. We aimed to present a case in which the location of the guidewire was verified by Y-shape visualization with an endocavity micro-convex probe after a cannulation attempt. Successful internal jugular vein catheterization was achieved with the assistance of the Y-shape imaging technique and the patient was avoided from multiple cannulation attempts.
