Diagnostic method, method for validation of diagnostic method, and treatment method
In a method for diagnosing and treating a patient having lesions in both arteries of left and right lower limbs. By determining that a lesion distal to an aortailiac bifurcation is to be treated first, catheters and an operation time can be reduced. The lesion to be treated first can be on a priority basis based on diagnostic data, deciding that a lesion proximal to the bifurcation is to be treated next, and then treating the lesions substantially continuously.
1. A treatment method for treating a patient having a lesion in each of left and right lower limb arteries connected via an aortoiliac bifurcation to the aorta, the treatment method comprising:
detecting electromagnetic waves obtained through a patient by irradiating the patient with electromagnetic waves, and obtaining electromagnetic wave information on the patient based on a changed electromagnetic wave;
identifying a plurality of lesions from the electromagnetic wave information with artificial intelligence, the plurality of lesions including one or more lesions in each of the left and right lower limb arteries;
acquiring distance information from the aortoiliac bifurcation to each of the plurality of lesions from the electromagnetic wave information with the artificial intelligence;
determining a lesion to be treated first among the plurality of lesions with the artificial intelligence based on the distance information of each of the one or more lesions in each of the plurality of bifurcated lumens, the lesion to be treated first being in one of the plurality of bifurcated lumens;
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 bifurcation of the patient; and
inserting a therapeutic catheter into a lumen of the catheter, projecting a therapeutic catheter tip of the therapeutic catheter from the catheter tip, and treating a lesion distal to the aortoiliac bifurcation first, and then projecting the therapeutic catheter tip of the therapeutic catheter from the catheter tip to treat a lesion more proximal to the aortoiliac bifurcation than the treated lesion distal to the aortoiliac bifurcation.
2. The treatment method according to claim 1 , further comprising:
treating of the lesion more proximal to the aortoiliac bifurcation than the treated lesion distal to the aortoiliac bifurcation using the catheter.
3. The treatment method according to claim 1 , comprising:
treating of the lesion more proximal to the aortoiliac bifurcation than the treated lesion distal to the aortoiliac bifurcation using the therapeutic catheter.
4. The treatment method according to claim 1 , wherein after treating of the lesion distal to the aortoiliac bifurcation, the method comprising:
removing the therapeutic catheter from the catheter; and
treating of the lesion more proximal to the aortoiliac bifurcation than the treated lesion distal to the aortoiliac bifurcation using a second therapeutic catheter.
5. The treatment method according to claim 1 , wherein the catheter is a guiding catheter, the method comprising:
using a catheter assembly including an inner catheter inserted in a lumen of the guiding catheter in the placing of the catheter tip of the catheter to at least the aortoiliac bifurcation of the patient.
