[Artificial embolization of cerebral arteriovenous aneurysms via the vertebro-basilar system].

Abstract

Data are presented on artificial embolization of arterio-venous aneurysms of the brain via the vertebro-basilar system in 12 patients. In one case the embolization was performed by way of vertebral artery catheterization through the axillary artery, in the remaining II cases--through the femoral artery. The embolization was carried out with the aid of polystyrene balls, 2 to 3 mm in diameter, numbering 8 to 40. In some cases the needed direction of the emboli movement was achieved by applying a magnetic field. No complications were encountered in the embolization via the vertebral system.
