Background
With the rapid development of heart surgery at home and abroad, the application of the arterial cannula in the heart surgery is more and more extensive. The femoral artery is a common part of CPB (extracorporeal circulation) peripheral catheter used in minimally invasive cardiac surgery, secondary surgery and thoracic aorta surgery, and the existing femoral artery intubation technique has an inherent problem that insufficient blood flow of the lower limb at the far end of an intubation tube can be caused in the surgery. In order to maintain sufficient CPB flow, the diameter of a femoral artery cannula needs to be equivalent to the internal diameter of a femoral artery of a patient, but the lower limb antegrade perfusion blood flow is greatly reduced, and the lower limb ischemia symptoms are easy to occur if corresponding strategies are not implemented.
In order to avoid ischemia at the distal end of the lower limb in the conventional femoral artery intubation, a 5F or 6F intubation or a suture bypass blood vessel is often placed at a remote position of the intubation, but the treatment is time-consuming and requires additional equipment support. At present, the conventional femoral artery intubation in clinic supplies far-end lower limbs by means of small blood flow and collateral circulation around the intubation. In this case, even if the lower limb is closely observed clinically, irreversible cell damage may already occur when clinical symptoms are evident, and still cause harm to the patient.
