Fogarty catheter embolectomy is a procedure used to treat arterial embolism by removing the blocked embolus from the artery through a Fogarty catheter. Indications: Patients with arterial embolism should have the procedure performed as soon as the patient’s general condition permits. The earlier the treatment, the better the result, preferably within 6~8 hours. Strive to save the limb. Contraindication: The only contraindication is that the time of arterial embolization is too long, and the distal limb has undergone extensive severe gangrene and necrosis. In addition, some patients with poor general condition, severe heart disease, high blood pressure, respiratory failure, etc. who cannot tolerate the operation should be cautious, and make good preoperative preparation if necessary.
