Discussion about endovascular treatment for traumatic intracranial pseudoaneurysms of internal carotid artery

Objective: To discuss the method and result of endovascular treatment for traumatic intracranial pseudoaneurysms of internal carotid artery. Methods: To fill the cavity with GDC or inject NBCA into the cavity of the pseudoaneurysms,occlude the parent artery with detachable balloon or coil,implant stent into the parent artery. Results: All the pseudoaneurysms in 17 cases were all cured,and brain infarction occurred in 1 case because of anaemia after occlusion of the parent artery. Conclusion: DSA of brain is the only trustable means to diagnose and study the disease.Endovascular treatment for traumatic intracranial pseudoaneurysms of internal carotid artery is a simple,minimal traumatic,secure and effective method.The effect of the injection of NBCA into the cavity of pseudoaneurysms need more observation and discussion.Of all the factors that can estimate the compensative capability of cerebral blood flow,hypovolemia and hypochromic were very important while deciding to occlude the parent artery.
