The patient is prepared by standing and walking so that the vein is maximally dilated, followed by accurate visual and palpatory mapping of the vein outline without marking the vein directly, only then can the vein be fully visualized during cold light fluoroscopy. Epidural or lumbar anesthesia is used. The patient is placed in the supine position with the affected limb elevated 30 degrees. I. High saphenous vein ligation: A parallel subinguinal incision is made to reveal the main trunk of the saphenous vein and all its branches; the saphenous vein is cut and ligated 5 mm below the connection point of the femoral saphenous vein; the main trunk of the saphenous vein is stripped out with a stripper in the thigh. Second, using the TriVex system of phlebectomy: the preparation is to reduce the brightness of the operating room shadowless lamp and to place the patient in a supine low head position; the size of the surgical incision is 3 mm, and the incision site should be balanced to maximize the removal of varicose vein tissue and reduce the number of incisions; the incision should be close to the varicose vein group, not on the varicose vein, and the size should be as large as possible to ensure complete placement of the planer tip; in the varicose One incision should be made at the proximal and one at the distal end of the varicose vein, one to insert the planer head and one to insert the cold light source; the incisions can be used alternately to reduce the number of incisions. C. Filling anesthesia: a TriVex cold light source with perfusion is attached to the pre-pressurized filling fluid; the cold light source is inserted at least 3-4 mm below the vein through the incision; the fluid is injected from the cephalic end to reveal the extent and contour of the varicose vein while separating it from the surrounding tissue. IV. Excision by TriVex planer: The cold light source and the planer tip are inserted subcutaneously through the vein from small incisions at both ends; the planer tip is inserted into the subcutaneous tissue surrounding the vein and gently slides along the side and underneath the tissue in an effort to remove more of the vein tissue. V. Speed of planer knife: the speed of TriVex planer knife in positive rotation mode is set at 700-1000rpm; for larger veins and sites with more scar tissue, as well as fibrotic tissue structures, an oscillating rotation mode with a speed of 7000rpm is appropriate; the skin is tensed during surgery to increase the tension of the epidermis and subcutaneous tissue, which can improve the safety of surgery. VI. Re-filling anesthesia: is the main component of this method, which minimizes petechiae and hematoma formation and ensures postoperative comfort. Postoperative management After completion of the surgery, the incision is closed with surgical tape without sutures. The author recommends that the surgical dressing be kept on the surgical site for 48 hours and that the affected limb be elevated. Patients are hospitalized for 2 to 8 days postoperatively, with an average of 4.89 days. If hematoma occurs, hematoma can be applied externally with Xylactol and can disappear after two weeks. Postoperatively, the pigmentation of the limb can be significantly reduced and all superficial phlebitis disappears. Minimally invasive aspiration resection is superior This procedure is suitable for cases of varicose veins in which the deep veins of the lower extremities are open. The procedure can be used for all cases of superficial varicose veins of lower limbs with pigmentation of lower legs, eczema-like dermatitis, ulcers and bleeding, but without history of swelling of lower limbs, combined with non-invasive examination of veins showing that deep veins are open. The biggest advantages of this procedure are: firstly, the number of incisions is small, each incision is only about 3mm, and two micro-incisions can be used to remove patches of varicose veins by introducing cold light source and power phlebectomy device respectively, and the incisions can be used alternately, which obviously reduces the surgical incisions. Secondly, varicose vein aspiration can be performed under direct vision, which simplifies the operation and significantly shortens the operation time. Thirdly, it avoids making incisions in the skin lesion area and reduces the chance of postoperative incision failure. When inflammation or hyperpigmentation exists in the varicose vein, an incision is made in the adjacent healthy skin and a cold light source with perfusion and a power phlebectomy device are introduced to remove the lesioned vein under direct vision, which avoids making incisions directly in the area of hyperpigmentation and phlebitis and removes the varicose vein more thoroughly than the traditional procedure. This reduces surgical trauma and the chance of postoperative wound failure. Fourth, the use of intraoperative pressurized irrigation solution not only serves to separate the subcutaneous tissue from the varicose veins at the surgical interface, but also has the effect of reducing hematoma and postoperative pain in the surgical area.
