Peripherally inserted central catheter (PICC) is widely used in clinical practice to protect patients' peripheral veins. However, various complications can occur during PICC placement, among which catheter rupture is rare and residual catheter retention can cause serious complications such as cardiac arrhythmias and pulmonary embolism in patients. Therefore, timely positioning and removal of the residual catheter are extremely important to ensure the safety of patients' lives. A case of a 19-year-old male with a residual PICC catheter is reported as follows.
