血吸虫病人脾脏病变的性质,意见不一。文献关于脾肿大的病因学机制亦有许多不同见解。许多作者认为脾脏大小与门静脉压力并无恒定关系。关于血吸虫病脾肿大的容积与脾内血管床的总容积的关系尚无报告。利用此种关系易于区别那些成比例的细胞和血管增生的单纯脾髓增殖性脾肿大的病例,和以充血性及脾窦扩大为主的不成比例的脾肿 Schistosomiasis spleen lesions of different nature. There are many different opinions about the etiology of splenomegaly in the literature. Many authors believe that there is no constant relationship between spleen size and portal pressure.
