The chiva surgery involves ligating and cutting the saphenous vein at the root of the thigh, as well as the five branches of the saphenous vein. However, the trunk of the saphenous vein is not stripped. 2. The varicose vessels still need to be stripped separately, which is the same as traditional surgery. 3. complications may arise from the surgery, mainly thrombophlebitis, recurrence of varicose veins, and pain in the lower leg, which can be relieved in most patients after 3 months of surgery or with local treatment. 4. 3 to 5 days of preparation are needed before surgery, which is mainly a time-consuming systematic examination of the blood vessels of the lower limbs. 5.The cost of surgery is generally about 6,000 yuan unilateral.
