1. A treatment method for treating a patient having a lesion in each of left and right lower limb arteries connected via an aortailiac bifurcation to the aorta, the treatment method comprising:
acquiring diagnostic information on the patient, the diagnostic information including image information;
measuring stenosis rates for the lesions in each of the left and right lower limb arteries from the image information;
comparing the stenosis rates for the lesions in each of the left and right lower limbs arteries;
determining with reinforcement-learned artificial intelligence among a plurality of different treatment scenarios that a lesion having a lower stenosis rate is to be treated first and a lesion having a higher stenosis rate is to be treated second based on one or more of an operation time, a number of medical devices used, and a cost of the number of medical devices used;
introducing a catheter from an artery of an arm of the patient, advancing and placing a catheter tip of the catheter to at least the aortoiliac aortailiac bifurcation of the patient; and
inserting a therapeutic catheter into a lumen of the catheter positioned, projecting a therapeutic catheter tip of the therapeutic catheter from the catheter tip, and treating the lesion having the lower stenosis rate first, and then projecting the therapeutic catheter tip of the therapeutic catheter from the catheter tip to treat the lesion having the higher stenosis rate second.
