Abstract
A method for diagnosing, validation of diagnosis and treating a patient having lesions in both arteries of left and right lower limbs. By determining that a larger vessel diameter lesion to be treated first, catheters and an operation time can be reduced is to be treated first on a priority basis based on diagnostic data, deciding that a smaller vessel diameter lesion is to be treated next, then treating the lesions substantially continuously.
Claims20
A treatment method for treating a patient having a lesion in each of left and right lower limb arteries connected via an aortailiac bifurcation, the treatment method comprising:
- 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 aortailiac bifurcation of the patient via an aorta 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 into one of the left and right lower limb arteries from the aortailiac bifurcation, and treating a larger vessel diameter lesion first in the one of the left and right lower limb arteries, the larger vessel diameter lesion being a chronic total occlusion and wherein the treating of the larger vessel diameter lesion first shortens or reduces operation times spent performing treatment of the lesions in the left and right lower limb arteries of the patient, and then projecting the therapeutic catheter tip of the therapeutic catheter from the catheter tip into an other of the left and right lower limb arteries from the aortailiac bifurcation to treat a smaller vessel diameter lesion.
