The dangers of great saphenous vein ligation

Saphenous vein ligation is a common method for treating varicose veins. For patients, having to use such surgical methods for treatment may have a certain impact on the body. However, if not treated, the harm to the patient will be greater. For such operations, it is generally necessary. If conservative treatment is possible, Chinese medicine massage and acupuncture can be used.

Causes of varicose veins Generally speaking, poor elasticity of the vein wall and excessive pressure in the veins are the direct causes of varicose veins. Other risk factors increase the chance of developing varicose veins, such as family history of varicose veins, long-term high abdominal pressure, overweight, pregnancy, long-term standing or sitting, lack of exercise, smoking, and deep vein thrombosis. Women tend to suffer from this disease more often than men. The age of patients is mostly between 30 and 70 years old.

Surgical steps : 1. Make an incision on the inner side of the femoral artery, and make a longitudinal or oblique incision that bends inward from the inguinal ligament downward. About 6cm long. 2. Separate the great saphenous vein, cut the skin and subcutaneous tissue, cut the superficial fascia on the inner side of the femoral artery, expose the oval fossa, and you can find the confluence of the great saphenous vein and femoral vein. The great saphenous vein trunk was isolated using curved hemostats. 3. Cut off the branches of the great saphenous vein and separate them along the venous trunk. Find out the branches such as the superficial iliac circumflex vein, superficial abdominal wall vein, superficial external pudendal vein, lateral femoral vein and medial femoral vein, and ligate and cut them one by one. The location and number of these branches vary greatly, so during surgery, this area should be exposed as much as possible, and each branch should be carefully searched until the great saphenous vein enters the femoral vein. 4. Ligation of the great saphenous vein: Draw a thick silk thread from the back of the great saphenous vein and ligate the great saphenous vein 0.5 to 1.0 cm away from the femoral vein. Clamp two hemostats at the distal end of the ligature, cut the vein between the clamps, and add sutures at the proximal end of the proximal clamps. 5. Insert and push the great saphenous vein stripper. Insert a hard or soft vein stripper downward from the distal end of the severed vein and push it downward along the vein. If resistance is encountered, it means that the venous tortuosity or the plane of the deep venous communicating branch may have been reached. After the cylindrical metal head of the stripper touches the membrane outside the skin, another small incision is made in the skin at the corresponding position to expose the vein at that location. The blood vessels are ligated at the upper and lower ends of the stripper head, and the vein is cut between the two ligatures.
