创伤后脑缺血是创伤性脑损伤后继发颅脑损伤的重要原因之一,颅脑外伤死亡的病人约90%都存在脑缺血。创伤后脑缺血将加重脑损伤,并将导致神经元和胶质细胞坏死和凋亡。创伤后脑缺血的机制尚待进一步研究,创伤后缺血的病理过程较脑梗塞后的缺血更复杂。随着影像学的广泛应用,发现颅脑创伤后患者出现缺血表现常提示存在潜在的脑血管损伤。脑血管损伤是创伤后脑缺血发生的主要原因。
Post-traumatic cerebral ischemia is one of the most important causes of traumatic brain injury secondary to traumatic brain injury. About 90% of traumatic brain injury patients have cerebral ischemia. Post-traumatic cerebral ischemia will aggravate brain damage and will lead to neuronal and glial necrosis and apoptosis. The mechanism of post-traumatic cerebral ischemia remains to be further studied. The pathological process of post-traumatic ischemia is more complicated than that of cerebral infarction. With the extensive application of imaging, found that the performance of patients with traumatic brain injury after ischemia often prompted the existence of potential cerebrovascular injury. Cerebrovascular injury is the main cause of post-traumatic cerebral ischemia.
