Diagnosis and endovascular treatment of midbasilar dissecting aneurysm.

The authors present the case of a patient with a midbasilar dissecting aneurysm successfully treated by staged bilateral endovascular occlusion of the vertebral artery. The clinical and the radiological features are presented with references to the literature, and the choice of endovascular rather than neurosurgical treatment is discussed in light to our previously reported experience about the treatment of unclippable vertebrobasilar aneurysms.
