A 26-year-old man presented to the emergency department with an accidental self-inflicted shotgun wound to the posterior right thigh with a pulsatile bleed. On arrival, the heart rate was 154 bpm with no measurable blood pressure. After resuscitation with 2 L crystalloid and 1 unit packed red blood cells, the heart rate decreased to 102 bpm; the systolic blood pressure was 80 mmHg. Pedal pulses were palpable on the left; no Doppler signals were appreciated on the right.
