毛细血管扩张症引起小肠出血的现状研究

Research on Current Status of Small Intestinal Bleeding Caused by Telangiectasia

摘要: 毛细血管扩张症是一种以毛细血管管径异常扩张、微血管壁脆性增加、通透性增加及血液外渗为特征的一组疾病。毛细血管扩张症发病率较低，仅占胃肠道恶性肿瘤的0.32%~0.37%，占消化道癌的0.02%~0.21%，但其病死率较高。

Abstract: Telangiectasia is a group of diseases characterized by abnormal dilation of capillary diameter, in-creased fragility of microvascular walls, increased permeability, and blood extravasation. Despite having a low incidence, it only accounts for 0.32%~0.37% of gastrointestinal malignant tumors and 0.02%~0.21% of gastrointestinal cancers, but telangiectasia has a high mortality rate.
