硬化栓塞剂治疗食管、胃底静脉曲张已愈来愈广泛地被用干临床。该法操作简便、损伤小、止血效果好。其使用方法有以下几类: 内镜下食管曲张静脉硬化疗法包括内镇直视下将硬化剂注入曲张静脉内(血管内法)和注入曲张静脉周围粘膜下(血管旁法)两种。此两种方法可单独使用,亦可同时并用。铃木指出,硬化剂注入静脉旁粘膜下可引起间质炎症细胞浸润→纤维化→管壁硬化;如注入曲张静脉内则引起血管内膜剥离(血管内膜炎)→血小板、血细胞聚集、凝集→血栓形成,使曲张静脉萎缩以至消失。
Hardened embolic agents for the treatment of the esophagus, varicose veins have been more and more widely used dry clinical. The method is simple, less damage, hemostatic effect is good. The use of the following categories: Endoscopic esophageal varicose veins sclerotherapy includes the town into the varicocele under direct vision (endovascular method) and the injection of varicose veins around the sub (subangular method) two. These two methods can be used alone, can also be used simultaneously. Suzuki pointed out that the influx of sclerosant into the paravenous paraventricular tissue can cause interstitial inflammatory cell infiltration → fibrosis → wall hardening; such as the varicose veins caused by intimal dissection (endocarditis) → platelets, blood cell aggregation, agglutination → Thrombosis, so that varicose veins even disappear.
