Microvascular Anatomy of Extreacranial and Cavernous Internal Carotid Artery(ICA)

• Kim JM

Abstract

Although lacking of unanimously accepted nomenclature and numbering system of the internal carotid artery (ICA) segments, recently adopted system may be applicable in terms of its simplicity and practical purposes. According to this seven-tier system, we briefly summarized the normal microvascualr anatomy of the ICA from the extracranial cervical (C1) segment to the clinoid (C5) segment of the ICA and surrounding structures with relevant schematic drawings. Also we presented a spectrum of normal variants and congenital anomalies with respect to the normal anatomy.
