摘要
目的 探讨外伤后脑浅表大静脉梗死的相关因素和治疗措施.方法 从2003年1月至2008年10月对74例脑浅表大静脉损伤按术中发现分为3组：1组：脑浅表大静脉损伤合并局部脑挫伤和脑内血肿、急性硬模下血肿.2组：脑浅表大静脉损伤合并局部脑挫伤和脑内血肿、急性硬模下血肿、损伤区颅骨骨折.3组脑浅表大静脉损伤合并损伤区颅骨骨折、急性硬模下血肿,无明显脑挫伤、脑内血肿,并按性别、年龄、术前GCS评分、脑疝情况分组.结果 1组28例,2组39例,3组7例,各组的损伤静脉不同,差异有统计学意义（P〈0.01）.1组和2组有37例患者合并有不同程度的脑梗死,3组有2例发生脑梗死.脑梗死与性别、年龄、术前GCS评分、脑疝均无关.结论 脑浅表大静脉损伤主要南局部颅骨骨折或对冲伤、剪切伤所致,合并有脑挫伤时脑梗死多见,术中应注意保护受损腩浅表大静脉及周围的静脉网,及时清除颅内血肿,必要时大骨瓣充分减压,降低颅高压,术后注意稀释血液,防止受损静脉栓塞.
Objective To analyze the correlative factors of traumatic embolism in superficial cerebral vein and explore their corresponding treatments. Methods A total of 74 cases were divided into 3 groups according to their injury mechanisms. Group A： traumatic brain injury in superficial cerebral vein with cerebral contusion, acute intracerebral hematoma and subdural hematoma in the same place; Croup B; traumatic brain injury in superficial cerebral vein with acute intracerebral hematoma, subdural hematoma and skull fracture in the same place; Group C： traumatic brain injury in superficial cerebral vein with acute subdural hematoma and skull fracture in the same place, without cerebral contusion or acute intracerebral hematoma. They were divided into different groups according to gender, age, pre-operative GCS and cerebral hemia. Results Among 74 cases, 28, 39 and 7 cases belonged to groups A, B and C respectively. There was significant difference among injured veins in three groups （P 〈0. 01）. Cerebral infarction was found in 37 cases in groups A and B while only 2 cases in group C. Cerebral infarction had no correlation with sex, age, pre-operative GCS and cerebral hernia. Conclusion Injuries in superficial cerebral vein are mainly caused by skull fracture, contre-coup injury and shearing force. Cerebral infarction often exists if there is cerebral contusion. It is necessary to protect injured primary superficial cerebral veins and ambient venous network, remove intracranial hematoma and large bone flap to reduce intracranial hypertension and dilute blood post-operatively to prevent venous embolism.
