The patient was placed in a flat position, and the surgical field was routinely disinfected and toweled. A longitudinal incision of 8 cm was made in the right groin in the body projection of the femoral artery, and the skin and subcutis were incised, and more clots were seen in the subcutis near the original puncture site, with a distribution of about 15 cm×15 cm, a large tumor cavity, more clots, more fat liquefaction necrosis, and the removed clots were nearly a curved disk. The deep fascia was incised and the femoral artery was found. A 3-mm diameter rupture was seen in the femoral artery with blood ejection, and the rupture was markedly edematous with local patch formation. The rupture was closed with 5-0 vascular sutures, and after completion, the distal vessels of the rupture pulsed well. The wound was flushed with iodine fluoride saline, and another hole was poked to place a rubber drainage tube. The gauze instruments were counted correctly, the subcutaneous and skin were sutured layer by layer, and the affected area was wrapped with pressure. The patient was in a stable condition with little bleeding during the operation. After the operation, the patient was returned to the extracardiac ICU.
