Cryosclerosis was developed at the end of the last decade. It is the endovenous cryoablation of the great saphenous vein and has been forgotten before the era of the endovenous ablation techniques began. The caused histomorphological changes of the vein weren't described before, especially, years after the procedure. A 31-year-old female patient underwent cryosclerosis 2 years ago. Because of the recanalization of the great saphenous vein and recurrent varicosity, high ligation, cryostripping and phlebectomy of varices were performed. During surgery, a saphenous vein piece was harvested to investigate the histomorphological effect of cryosclerosis. Histological findings verified that recanalization had occurred, the vein wall had undergone remodeling, and the picro-sirius red stain showed collagen deposition in the whole vein wall. Cryosclerosis seems to result in the remodeling of the vein wall.
冷冻硬化术是在过去十年末发展起来的。它是大隐静脉的静脉内冷冻消融术，在静脉内消融技术时代开始之前就已被遗忘。此前未描述过该手术导致的静脉组织形态学变化，尤其是术后数年的变化。一名31岁女性患者于两年前接受了冷冻硬化术。由于大隐静脉再通和复发性静脉曲张，进行了高位结扎、冷冻剥脱术和曲张静脉切除术。手术过程中，采集了一段大隐静脉组织以研究冷冻硬化术的组织形态学效果。组织学检查结果证实发生了再通，静脉壁发生了重塑，苦味酸天狼星红染色显示整个静脉壁有胶原沉积。冷冻硬化术似乎会导致静脉壁重塑。
