Electrical burns cause damage to the cardiovascular system through different mechanisms. Immediate cardiac arrhythmia is one of the common consequences. A large vessel blow out due to an electrical burn is rarely documented. It is often undetected due to its "silent" symptoms. This article reports a delayed obturator artery rupture in a 32-year-old male patient 6 weeks after he sustained severe high-voltage electrical burns. The vessel injury was treated with computed tomography (CT)-aided embolization. The patient recovered to an ambulatory status 10 weeks after the injury.
