In clinical practice, if a patient has varicose veins in the feet, foam sclerotherapy injection is recommended. Foam sclerotherapy injection for varicose veins in the feet has the advantages of less trauma, less intraoperative bleeding, exceptionally few postoperative complications for patients, and exceptionally fast recovery for patients after surgery. Moreover, if patients are treated with foam sclerotherapy injections, they can be performed on an outpatient basis without the need for hospitalization, and generally, patients can leave the same day. It is important to note that the patient is compressed at the puncture site for about half an hour during this time and that the patient wears medical venous compression stockings, which can enhance the clinical outcome. After the patient is treated, it is best to have a venous ultrasound of the lower extremities every six months, which can effectively prevent the patient from recurrence after the surgery. Patients with varicose veins in the feet should pay more attention to rest, elevate the affected limbs when resting, and avoid prolonged standing and sitting.
