%X Peripherally inserted central catheter (PICC) placement under real-time ultrasound guidance has emerged as a favorable procedure in children as a method to efficiently obtain central access. Nevertheless, small infants with hemodynamic instability are at high risk of complications and extra precautions are necessary. We present a case of an inadvertent arterial placement of a PICC in a two-month-old infant with dilated cardiomyopathy and decompensated heart failure. Differentiation of arteries and veins under ultrasonographic evaluation may sometimes be difficult when the applied tourniquet pressure exceeds the patient's arterial blood pressure. In particular, arterial flow can be easily compromised by applying tourniquet pressure in small children with low blood pressure. A thorough understanding of the upper extremity vascular anatomy, basic scanning techniques, and meticulous preparation especially in small infants with hemodynamic instability are essential for maintaining the safety and efficacy of this procedure.
