[Consequences of a misplaced central venous catheter].

Central venous catheter (CVC) is useful for prolonged intravenous treatment, but not without risk. This is a case report of a 21-year-old male with a rare incident of CVC misplacement from the right subclavian vein to the left. The misplacement caused severe discomfort and possibly secondary thrombosis (VT) of deep cervical veins. The CVK was removed, and the patient was treated with rivaroxaban for three months, which made him recover without sequelae. VT, due to CVC, can cause a potentially life-threatening pulmonary embolism. CVC placement should be controlled by X-ray, and abnormal findings should be communicated.
