The clinical and angiographic characteristics of vertebral artery (VA) aneurysm were evaluated to demonstrate the safety and efficacy of endovascular techniques of VA aneurysms. ⋯ This series demonstrates the safety and efficacy of multimodality of endovascular techniques for VA aneurysms.

Neuroendoscopy has become an integral part of neurosurgery, in particular in the ventricular system. Obstructive hydrocephalus secondary to intraventricular hemorrhage (IVH) is a good indication for neuroendoscopic surgery. We evaluated its efficacy and limitations in these patients. ⋯ Endoscopic management of severe IVH with obstructive hydrocephalus allows effective reduction of the amount of ventricular blood and improves level of consciousness. Future refinement in instrumentation and discreet case selection may make this method more applicable and effective.

The purpose of this study was to investigate the characteristics of six patients with dural arteriovenous fistula (DAVF) with drainage directly into the perimedullary venous system. In five patients with subarachnoid hemorrhage (SAH), cerebral angiography revealed a DAVF with spinal venous drainage located at the petrosal sinus in one, at the tentorium in one, and at the craniocervical junction in four. ⋯ Patients had no myelopathy when the venous drainage was limited to the cervical cord; myelopathy was present when the venous drainage descended toward the conus medullaris. Diagnosis of a DAVF presenting with myelopathy is more challenging than of those presenting with SAH.
