高血压是原发性脑出血最主要的原因。关于急性高血压性脑出血理想血压的控制问题一直争论不休。一方面,血压持续性显著升高不仅能引起再出血,而且会增加脑血流量和颅内压;另一方面,在血肿周围有一局灶性缺血区,降低血压从理论上说会进一步加重缺血。但Meyer和Bauer认为有效的降 Hypertension is the most important cause of primary cerebral hemorrhage. There has been controversy over the control of the ideal blood pressure in acute hypertensive intracerebral hemorrhage. On the one hand, a significant increase in BP persists not only to cause rebleeding but also to increase cerebral blood flow and intracranial pressure; on the other hand, there is a focal ischemic area around the hematoma which may theoretically be further aggravated Ischemia. But Meyer and Bauer think the drop is effective
