Patients with primary varicose veins mostly have no local symptoms in the early stage, but the following clinical manifestations may appear gradually. 1.The affected limbs often feel soreness, dullness, swelling and pain, easy fatigue and weakness. 2.The superficial veins of the affected limbs are bulging, dilated, varicose, or even tortuous or lumpy, which is more obvious when standing. 3.Swelling: slight edema may appear in the ankle and dorsum of the foot, and mild edema may also appear in the lower part of the calf in severe cases. 4. Complications: (1) Nutritional changes of the skin: thinning of the skin, flaking, itching, pigmentation, eczema-like dermatitis and ulcer formation. (2) Thrombotic superficial phlebitis: pain at the varicose veins, presenting red, swollen hard nodules and striae with pressure pain. (3) Bleeding: acute bleeding due to trauma or spontaneous rupture of varicose veins or small veins. For patients with lower limb superficial varicose veins accompanied by lower limb distension or edema or obvious pigmentation or ulceration, surgery is the first choice to eliminate or relieve symptoms and ensure long-term efficacy. Our vascular surgery department routinely performs high ligation and stripping of large and small saphenous veins with punctate stripping of varicose veins and small incision traffic vein ligation to treat superficial varicose veins in the lower extremities.
