Cavography with hydrogen peroxide. Accidental injection of hydrogen peroxide into the inferior vena cava

Contrast cavography during removal of a vena cava filter in patients treated via thrombectomy for pulmonary embolism is a widely performed procedure, which may involve potentially serious complications if the human factor fails. Accidental injection of hydrogen peroxide (H2O2) after mistaking it for contrast material can have fatal consequences. We present the case of a patient who was accidentally injected with a high quantity of hydrogen peroxide. The preparation of a preoperative checklist, the amount of H2 02 injected and the operator’s skill in aspirating the substance are decisive factors in avoiding such complications.
