Essential vascular anatomy of the cranial base that neurointerventionists need to know

Abstract

Precise knowledge of vascular anatomy is of extreme importance not only for neurosurgery but also for neuroendovascular treatment. In certain endovascular procedures such as dural arteriovenous fistula or skull base tumor embolization, we need to be able to predict the anastomosis which may not be visible on the angiogram using knowledge of anatomy in order to avoid complications. Arterial anastomosis comprises embryonically segmental artery anastomosis and anastomosis which share common territory. In this article, the arterial anastomosis around the orbit, the cavernous sinus, the posterior fossa and the craniocervical junction is described in detail.
