Abstract
The incidence of lower extremity varicose veins is higher in the disease of venous system,and surgical treatment is the main treatment method of lower extremity varicose veins.With the advancement of technique and the development of minimally invasive concept,endovenous thermal ablation(EVTA)has become the first choice in the guidance of the treatment of lower extremity varicose veins depended on its series of advantages include small trauma,rapid recovery after surgery,low incidence of complication and high closure rate.At present,EVTA mainly includes intracavitary radiofrequency ablation(RFA),endovenous laser ablation(EVLA)and endovenous microwave ablation(EMA),which takes heat on target vessel through different thermal ablation equipment,and uses thermal energy to destruct the endothelial cells of blood vessel and collagen fibers in the vascular wall.Then,the contracted lumen forms the fibrous strands,thus reaches the aim that closes target vessel.Different EVTA surgical mode has different mechanism of action,therapeutic effect and incidence of complication,as well as the application range.This paper summarized the routinely surgical mode of EVTA and the clinical application of that in the past 5 years,which can provide references for reasonable choosing the mode of thermal ablation and the equipment,and can provide helps for preventing the complication of thermal injury.关键词
