Abstract: Stress Ulcer is one of the most heavily complications of cerebral stroke. Thepathological mechanism is unclear. It mostly represents of hematemesis, hemafecia or both of them.The most serious consequence is occur of hemorrhage shock. The incidence rate of Stress ulcer (SU)in the cases of acute cerebral hemorrhage is higher than that of acute cerebral infarction, especiallyin the cases of brain stem stroke. The incidence rate of SU is higher in patients with consciousdisturbance.The occurance makes brain damage more seriously and may result in multipleorgan failure. The incident rate of death is especially higher in patients of acute cerebral strokecomplicated by SU than in patients of non-complicated by SU. The patients of acute cerebral strokecomplicated by SU have a poor prognosis, and preventive measures should be made at early stage.

摘要： 应激性溃疡是卒中最严重的并发症之一,发病机制不清。多表现为呕血、便血或二者兼有,严重者可出现失血性休克。急性出血性卒中并发应激性溃疡的发生率明显高于急性缺血性卒中,病变累及脑干时尤为突出。伴意识障碍的患者并发应激性溃疡的发生率较高。其发生可加重脑损害和出现多器官功能衰竭,对卒中预后影响较大。并发应激性溃疡的卒中患者病死率明显高于未并发者。卒中并发应激性溃疡预后不良,应早期识别其发生的危险因素，从而积极预防及治疗。
