After more than ten years of clinical practice, we have experienced the rapid development of vascular surgery from traditional techniques to minimally invasive hybrid techniques. At the present stage, the advanced degree of vascular surgery technology concept and equipment compared with ten years ago is a world of difference. Many disease treatment concept specialist doctors need to update quickly, non-specialist doctors lagging behind is inevitable, varicose veins is not a big disease, but it is not easy to do well. People are originally animals that walk on all fours, evolution has liberated hands, but also need to pay the price. Varicose veins are one of them. The calves are supposed to be the end of blood circulation and have the weakest blood vessel walls, because of standing, the veins are under the highest pressure instead, and it is not surprising that varicose veins arise if combined with long term standing and pregnancy. What are the common treatment methods? Varicose veins are treated in a variety of ways, and patients are often seen going through acupuncture, massage, bloodletting therapy, and long periods of oral medication. Dr. Su says: surgery is the most effective solution and nothing else needs much consideration. The history of surgery for varicose veins in the lower extremities is more than 100 years old. 20 years ago, the method was just to cut along the saphenous vein wherever there was vasodilatation, with a shocking scar, and then do it again after a few years of recurrence, not because the patient didn’t care, but because of the age limit. The real development of surgery to minimally invasive is still the last 20 years (limited by the uneven medical conditions in China, the worst and the best surgical solutions have always coexisted). The Trivex (transillumination spinotomy) surgical device involved in the internship is actually the same principle as liposuction; Seps surgery, if applied to patients with severe liposclerosis, can significantly reduce the damage, and patients with special conditions have obvious advantages; Laser surgery is the best surgical solution before Venefit surgery, but there are problems of incomplete closure of too thick vessels, high recurrence rate, and easy The Venefit procedure is the best solution before Venefit, but it has the problems of incomplete closure of too thick blood vessels, high recurrence rate, and easy to damage the nerve tissue around the blood vessels. What effect can Venefit achieve? 1.Vascular luminal closure is rapid and the possibility of recanalization is low The mechanism of Venefit is to release radiofrequency energy by placing a catheter into the vein, which acts directly on the vein wall under the monitoring of an ultrasound probe to rapidly cause fibrosis in the vein, contraction of the vein lumen and closure of the vessel to achieve the purpose of treatment. The principle is similar to Laser, but because of the design advantage, the energy release is more uniform and still has a good closing effect on overly distended vessels. This internationally popular endovenous treatment technology for varicose veins in the lower extremities has been approved by the FDA (U.S. Food and Drug Administration) in 2006 and has been proven to be one of the safest and most effective treatments for varicose veins in the lower extremities after nearly 10 years of evidence-based medical trials. 2.Vascular ultrasound is monitored by a doctor throughout the whole process Ultrasound, the vascular surgeon’s tool. Ultrasound is a necessary skill for a well-trained vascular surgeon. The status quo in the vast majority of hospitals is that doctors go for treatment based on ultrasound findings. If there is an error in the ultrasound examination, an experienced specialist can treat the patient with clinical experience and the patient will not be delayed. The non-specialist doctor encountering a similar situation in the process of screening patients is more at his or her own peril. One case is a patient with recurrence of varicose veins after surgery, and the ultrasound shows that the trunk was not removed, but only the superficial veins, so recurrence is a matter of time. In the other case, local ultrasound revealed saphenous vein reflux and a localized varicose vein mass below the medial knee, which routinely must have stripped or closed the saphenous vein. On ultrasound scan while standing, the saphenous vein as a whole was not abnormal, but the small saphenous vein was significantly thickened. If the doctor does not have an ultrasound instrument in hand, blindly removing the saphenous vein will inevitably result in recurrence. 3.Say NO to inguinal incision High ligation and stripping is the milestone procedure of varicose vein treatment plan, and domestic has followed the five major branches ligation + stripping for many years, and gradually developed to the direction of small inguinal incision, but it can’t get rid of the problem of inguinal incision. In contrast, venefit combined with intraoperative ultrasound monitoring, the inguinal vessels are directly closed and no incision is needed anymore. It must be understood that sensitive areas are rich in peripheral nerves and that wounds can lead to adhesions of nearby cutaneous nerves causing abnormal sensation of the skin and discomfort. The ultrasound is operated under close direct vision, and the incision in this area is said to be NO.
