硬化疗法是使曲张静脉迅速形成血栓性静脉炎并使其消失的方法。使用的硬化剂大部分为界面活化。剂,效果几乎无差别。笔者使用ETP法(乙醇—凝血酶—乙氧硬化醇法)。对粗大的曲张静脉,在血管内注入无水酒精和乙氧硬化醇,破坏血管内膜,为防止拔针时出血,使用300～400单位的凝血酶。在静脉瘤内迅速形成血栓性静脉炎。对细的曲张静脉,注入较困难,对血管内注入失败或是存在内部静脉扩张症的,可在粘膜下注入1%乙氧硬化醇和少量的凝血酶。
Sclerotherapy is a method of rapidly causing varicose veins to thrombophlebitis and causing it to disappear. Most of the hardeners used are interface activated. Agent, the effect is almost no difference. I use the ETP method (ethanol - thrombin - ethoxylated alcohol method). On the coarse varicose veins, intravascular injection of alcohol and ethanol ethoxylate sclerosis, destruction of vascular intima, in order to prevent bleeding when pulling the needle, the use of 300 to 400 units of thrombin. Thrombophlebitis develops rapidly within the vein. For thin varicose vein, the injection is more difficult, the failure of intravascular injection or the presence of internal venous dilatation, submucosal injection of 1% ethoxylated alcohol and a small amount of thrombin.
