咯血是肺結核严重而普遍的症状,发生率高达90％,低者17％,平均50％,某些肺科医院統計因咯血急診占急診总数74.6％。咯血除引起病人心理极端惊恐外,并能造成严重併发症如窒息死亡。本文就肺結核咯血机制及其处理作一槪述。【肺結核咯血的原因】肺結核咯血原因甚为复杂,可以在各种不同的病变程度、病变性貭及不同的阶段中发生,归納有下列解說: (一)Rasmasen和Bogen认为結核性纤維空洞壁由于肉芽組織与纤維組織曾生的关系,空洞壁的血管受其影响而变成凸出形成血管瘤,基于形态改变,血管壁变薄易受空洞內压影响及炎症侵蝕而破裂出血,急性大咯血者死后經病理証实,多半系空洞壁的血管瘤破裂出血。(二)結核桿菌具有将
Hemoptysis is a serious and common symptom of tuberculosis. The incidence rate is up to 90%, the lower is 17% and the average is 50%. In some pulmonary clinics, the total number of emergency cases is 74.6% due to hemoptysis. In addition to causing patients with hemoptysis extreme extreme panic, and can cause serious complications such as suffocation death. This article makes a brief account of the pulmonary tuberculosis hemoptysis mechanism and its treatment. The causes of pulmonary tuberculosis hemoptysis Tuberculosis hemoptysis is very complex and can occur in a variety of different degrees of disease, lesions and different stages, summarized the following commentary: (a) Rasmasen and Bogen that tuberculous fibrous cavity walls Due to the relationship between granulation tissue and fibrous tissue, the blood vessels of the empty wall become bulged to form hemangiomas. Based on the morphological changes, the thinning of the blood vessel wall is easily affected by the internal pressure of the cavity and the erosion of the inflammation and rupture of the hemorrhage. The acute After the death of hemoptysis confirmed by pathology, most of the empty wall of the hemangioma rupture bleeding. (B) Mycobacterium tuberculosis will have
