Microsurgical resection of an intramedullary glomus arteriovenous malformation in the high cervical spinal cord: retrograde dissection techniques of the nidus located between spinal tracts.

abstract：BACKGROUND:Many approaches for clipping anterior communicating artery (ACoA) aneurysms are reported in the literature. We describe here a new approach called "low anterior interhemispheric approach" for clipping of ACoA aneurysms. MATERIALS AND METHODS:A low anterior interhemispheric approach utilizing a unilateral fr...
