Growing Thrombosed Dissecting Aneurysm of the Vertebral Artery after Endovascular Proximal Artery Occlusion: the Role of the Vasa Vasorum / 신경중재치료의학

ABSTRACT

Proximal artery occlusion is one of several treatment methods for ruptured vertebral artery dissecting aneurysm (rVADA). However, that treatment may be incomplete and the risk of rebleeding should not be ignored. By contrast, mass effect, such as symptoms and signs of brain stem compression, ensuing after that treatment and rVADA occlusion, has not been reported in English literature. We experienced such a rare case of brain stem compression ensuing 3 months after VADA occlusion by endovascular proximal artery occlusion. To reduce the mass effect, surgery was performed with surgical specimen processed histologically. The clinical and radiological data of the case, its probable mechanism, and histological findings will be described and discussed here.
