颅内段椎基底动脉夹层动脉瘤诊疗研究进展

Advances in the diagnosis and treatment of intracranial vertebrobasilar dissecting aneurysms

颅内段椎基底动脉夹层动脉瘤(IVBDAs)是发生于椎动脉颅内段和基底动脉的以动脉瘤形成为主要形态学改变的动脉夹层,发病原因及确切机制尚不完全明确。其临床表现不具有特异性,还可能随时间进展演变转换,影像表现复杂多变,人们对IVBDAs的流行病学、自然病史、病因及发病机制、诊断方法及治疗策略尚存有争议,现参考近年发表的文献资料,综述IVBDAs的研究进展。

Intracranial vertebrobasilar dissecting aneurysms (IVBDAs) are arterial dissections that occur in the intracranial and basilar arteries of the vertebral artery with aneurysm formation as the main morphological change. The causes and precise mechanism of IVBDAs are not clear. The clinical manifestations of IVBDAs are non-specific, complex and varied, and may evolve and transform over time. The imaging manifestations are complex and varied as well. There are still controversies about the epidemiology, natural history, etiology and pathogenesis, diagnostic methods and treatment strategies of IVBDAs. The paper reviews the recent literature on IVBDA and summarizes research development.
