Intravascular graft stent treatment of a ruptured fusiform dissecting aneurysm of the intracranial vertebral artery: technical case report.

Objective And Importance: An innovative stenting technique to treat a difficult case of a fusiform aneurysm of the intracranial vertebral artery (VA), with restoration of the vessel lumen, is described.

Clinical Presentation: A 58-year-old patient experienced sudden pain in the upper cervical spine, followed by a severe headache. He underwent computed tomographic evaluation, which demonstrated subarachnoid hemorrhage in the prepontine cistern.

Internal shunting in small vessel reconstruction: an experimental study.

We describe the experimental use of an endoluminal shunt in different procedures for small vessel reconstruction. Since the arteries used in this work are similar in diameter to those of the brain, this method could be applied to human vascular surgery.

Development of the Spanish version of the Systematized Nomenclature of Medicine: methodology and main issues.
