血友病是由于血浆凝血活酶因子缺乏,致凝血过程中不能形成足够的活动性凝血活素,从而发生血液凝固障碍。一般可分为三型:甲型:缺乏抗血友病球蛋白(简称AHG);乙型:缺乏血浆凝血活酶成份(简称 PTC);丙型:缺乏血浆凝血活酶前质(简称 PTA)。我科自1958年至1962年见到PTC 缺乏症2例,PTA 缺乏症1例,另1例未定型,兹将各例主要临床表现及处理经过报告如下: Hemophilia is due to lack of plasma thromboplastin factor, resulting in the process of coagulation can not form enough active thromboplastin, resulting in blood clotting disorders. Type A: the lack of anti-hemophilia globulin (referred to as AHG); B: lack of plasma thromboplastin component (referred to as PTC); C: lack of plasma thromboplastin precursor (referred to as PTA) . Our department from 1958 to 1962 saw PTC deficiency in 2 cases, 1 case of PTA deficiency, the other 1 cases are not stereotypes, the cases will be the main clinical manifestations and treatment are reported as follows:
