Saphenous varicose veins are common venous disorders. The veins of the human lower extremity are divided into superficial and deep veins. The superficial veins are located under the skin, mainly the great and small saphenous veins, and the deep veins are located in the middle of the muscle, parallel to the arteries of the lower limbs. There are many valves in the veins, which make the blood flow in one direction to ensure the normal return of blood from the bottom to the top and from the superficial to the deep. How does varicose saphenous vein develop? Congenital weakness of the vein wall is an important factor. Also, varicose veins are associated with pressure on the legs. When the leg is subjected to any pressure, the superficial veins become overloaded and stretch, resulting in the valves in the veins not closing completely and blood flowing backwards, thus increasing the pressure in the veins and causing the veins to expand, elongate and bend with the accumulation of blood, resulting in varicose veins. Who is prone to saphenous varicose veins? Teachers, surgeons, nurses, hairdressers, lathe workers, salesmen, etc. who work standing up, people who often sit and exercise less, people who are often constipated, and people who are obese or tall are prone to this disease, and heredity is also related to this disease, as some families have many people suffering from varicose veins. The main clinical manifestations of varicose veins include heaviness, weakness, swelling and pain in the affected limbs after walking, activity or labor, a greenish protruding blood vessel in the legs, and in severe cases, sinuous expansion, bulging and bending of superficial veins in the lower limbs in the shape of a ball, skin pigmentation, subcutaneous tissue sclerosis, and even eczema and ulcer formation. Varicose veins are most often seen in the lower extremities, especially the saphenous vein in the inner calf and the small saphenous vein in the back of the calf. If the disease continues to progress when the valves of the communicating veins are disrupted, mild swelling of the ankle and trophic changes in the skin of the foot and boot area may occur, including skin atrophy, desquamation, pruritus, hyperpigmentation, hard nodules of skin and subcutaneous tissue, eczema, and ulcer formation. The diagnosis can be made based on the clinical presentation. Minimally invasive treatment: Our vascular surgery department adopts minimally invasive treatment of saphenous varicose veins with punctiform peeling, which is less traumatic and less painful for patients, and allows them to move on the ground the day after surgery. It has the following advantages: (1) simple operation, small incision or even no incision, which is suitable for the aesthetic needs of the majority of patients. (2) Short hospitalization time and low cost (3) Quick recovery after surgery and can be discharged from hospital in a short time (4) Almost no complications such as postoperative infection.
