颅内动脉瘤是一种致死率、致残率高的脑血管疾病,其病因仍不完全清楚,是造成蛛网膜下腔出血的最常见原因。DSA一直被认为是诊断颅内动脉瘤的“金标准”[1],被认为是确诊动脉瘤的必行检查。随着近几年来医学影像的飞速发展,CTA、MRA、介入等影像技术逐渐应用于临床,不仅减少了对患者的创伤,还具有操作简便等优点,为颅内动脉瘤的诊治提供了重大帮助。一、资料与方法1.临床资料:2002年1月至2011年12月川北医学院附属
Intracranial aneurysm is a fatal, high morbidity of cerebrovascular disease, the etiology is still not fully understood, is the most common cause of subarachnoid hemorrhage. DSA has long been considered the “gold standard” for the diagnosis of intracranial aneurysms [1] and is regarded as a necessary examination for the diagnosis of aneurysms. With the rapid development of medical imaging in recent years, imaging techniques such as CTA, MRA and interventional have gradually been applied to clinical practice, which not only reduces the trauma to the patient but also has the advantages of easy operation and so on, which provides great help for the diagnosis and treatment of intracranial aneurysms .
