脑出血继发桥脑出血的病理与临床

Clinical and pathological studies of secondary pontine hemorrhage in cerebral hemorrhagre

报告２７例脑出血继发桥脑出血的临床与病理资料。所有桥脑出血与原发出血灶无直接形态学联系，其中１２例起病时做了头部ＣＴ扫描，１１例没发现桥脑出血，证明桥脑出血为继发性远隔性损伤。继发桥脑出血根据形态的大小可见动脉性和静脉性出血，多发生在原发灶的同侧。继发桥脑出血与桥脑的动脉受牵拉、血管痉挛、内皮细胞缺血缺氧、小静脉回流障碍、高血压等因素有关。

Abstract This paper reports the clinical and pathological materials of 27 cerebral hemorrhage associated with secondary pontine hemorrhage. All the pontine hemorrhages have no direct morphological relation with original hemorrhage foci.Twelve of patients have done CT exam after onset, eleven of them were without secondary pontine hemorrhage. This result demonstrates that the pontine hemorrhage was secondary remote lesion. The damaged arteries and veins of secondary pontine hemorrhage were mainly located at the same side of original foci.The related factors of secondary pontine hemorrhage are stretch and spasm of pontine arteries,ischemia of endothelias cells, obstruction of small veins and hypertention et al.
