Arterial Anatomy of the Parasellar Area
1Department of Neurosurgery, Tokai University School of Medicine, Isehara, Kanagawa Japan.
Abstract:
The arterial anatomy of the parasellar area is complex in that it deals with extracranial-intracranial anastomosis and supply to various cranial nerves in a small area. Pathologies such as hypervascular tumors and shunts are not uncommon and require good knowledge of anatomy in planning the treatment. In this article, the basic anatomy of the arterial supply in this region is discussed, covering the origins, territories, relation to the cranial nerves, and the connections among different systems.
