桥脑出血分为原发性和继发性二种。前者是出血原发在桥脑,后者是在大脑半球出血的同时,继发桥脑出血,它比原发性桥脑出血为多见。其出血的病灶常较小,桥脑的定位征状不常显示出来,临床上诊断亦很困难。其出血的机制认为是半球大量出血,顱内压增高,由于脑干受压和移位而引起的。而则认为是半球和桥脑出血是同时发生的,和脑干移位没有关系。原发性桥脑出血很少见,国内尚无报导。茲将我们遇到的二例报告如下,并结合文献,就其发病率,病理和临床略加讨论。 Pontine hemorrhage is divided into primary and secondary two. The former is the primary bleeding in the pons, the latter is bleeding in the cerebral hemisphere, secondary to pontine hemorrhage, it is more common than primary pontine hemorrhage. The bleeding lesion is often small, Pacema positioning is not often displayed, the clinical diagnosis is also very difficult. The bleeding mechanism that is a large number of hemispheric hemorrhage, increased intracranial pressure, due to pressure and displacement of the brainstem caused. And that is the hemispheric and pontine hemorrhage is occurring at the same time, and brain stem shift has nothing to do. Primary pontine hemorrhage is rare, there is no report in China. We will encounter two cases reported below, combined with the literature on its incidence, pathology and clinical slightly discussed.
