The Department of Vascular Thyroid Ventral Hernia Surgery (hereinafter referred to as the Blood Nail Hernia Surgery) has successfully developed a minimally invasive surgical approach to the treatment of varicose veins of the lower extremities with the TriVex system. The procedure is widely indicated for all cases of superficial varicose veins in which the deep veins are patent. The procedure can be used in patients with superficial varicose veins in the lower extremities with skin pigmentation, eczema-like dermatitis, ulcers, bleeding but without swelling of the lower extremities, combined with non-invasive venous examinations showing that the deep veins are patent. Dozens of cases of this procedure have been successfully performed in the Department of Hernia Surgery of Blood A. Patients recovered smoothly after surgery and were able to get out of bed the next day after surgery (a few patients had mild subcutaneous bruising, but it subsided in a few days), and no deep vein thrombosis or other complications occurred in the lower limbs. Minimally invasive surgery for saphenous varicose veins has become a developmental trend, and TriVex system of venous spinotomy for varicose veins is the most advanced method for the treatment of this disease today, compared to traditional high ligation and stripping, which has the disadvantages of large trauma, unsightly, painful and slow recovery, and many postoperative complications, such as bleeding, hematoma, wound infection, skin necrosis, saphenous nerve injury, superficial phlebitis and deep vein thrombosis, etc. . The advantage of TriVex system vein rotation is that the incision is few and small, only 3 mm in the calf, which has unique advantages for women with limited limb varicose veins. The second advantage is the short operative time and quick postoperative recovery, as the patient can be out of bed after the next day and can be discharged from the hospital in an average of 6 days. The procedure is performed under direct vision with a suction excision of varicose veins, which is complete, not easy to miss and has a low recurrence rate. It is suitable for different types of varicose veins and varicose veins that have been treated with injections and can avoid making incisions in the area of skin lesions (e.g. ulcers, eczema, etc.), reducing the chance of non-healing incisions or infections after surgery.
