A 2-month-old baby boy, 52 cm in height and weighing 4.6 kg, underwent a Blalock-Taussig shunt operation under general anesthesia. The authors checked the internal jugular vein (IJV) using an ultrasound apparatus with a 5/10-MHz probe (TiTAN, SonoSite Co., Tokyo, Japan) at a mid-portion of the neck. We observed a 3.9-mm-wide and 7.6-mm-deep IJV for central venous catheter (CVC) placement. ⋯ We placed the CVC into the left IJV instead of the right IJV. We speculated that the guidewire had advanced into the IJV; however, we could not advance the tip of the guidewire from the IJV to the brachiocephalic vein because the angle between the IJV and the brachiocephalic vein was 90 degrees. We could have advanced a J-type guidewire from the IJV into the brachiocephalic vein.
