Cranial Vascular Anatomy and Its Variations

As cerebrovascular therapeutic procedures become even more common, the need for detailed understanding of cranial vascular anatomy, together with the variations that may be encountered, is very important. These anatomical variations actually reflect the embryological development of the organism, the phylogeny of the species as well as the 4-dimensional status of anatomy. This chapter will briefly discuss intracranial vascular anatomy, along with the most important clinical anatomic variations.
