Clinically, when an elderly person in his 70s has varicose veins, it is recommended that the patient undergoes early surgical treatment. Of course, 70+ year olds may have other underlying diseases in combination, so the preoperative examination must be perfect and contraindications to surgery must be ruled out, so that the patients can undergo surgical treatment in a safe state. Varicose veins are a common disease in vascular surgery, occurring mostly in the lower extremities. The mechanism of occurrence is venous insufficiency of the lower limbs, with blood reflux within the deep and superficial veins of the lower limbs, causing venous hypertension of the lower limbs, tortuous expansion of the superficial veins of the lower limbs, lower limb soreness, fatigue, itching, hyperpigmentation, eczema-like changes, ulcer formation and other symptoms. For 70-year-old patients, the symptoms may often be more serious, especially for patients who have already had more serious complications such as lower limb ulcer formation, such ulcers are difficult to heal, often for several years, seriously affecting the patient’s quality of life. 70-year-old patients without significant cardiorespiratory dysfunction should be taken to minimally invasive surgical treatment of varicose veins so that the patient’s trauma will be less, and the recovery will be quicker after the operation.
