Neurovascular anatomy: a practical guide.
Students of cerebrovascular anatomy and physiology tend to model their learning based on normal patterns of blood flow. As such, the focus tends toward arterial physiology and pathology with less than adequate understanding of the significance of the venous system. This article presents a different approach to neurovascular anatomy, starting with the venous system and demonstrating both normal and pathologic states. It reviews the cerebral circulation with attention to the microsurgical relationships, angiographic patterns, and fusion of dual-volume imaging. The importance of bony, sulcal, and ventricular anatomy is presented as it relates to the angiographic representation of pathologic lesions. Examples are given of anatomic variants seen with the operating microscope, biplanar angiography, and three-dimensional rotational angiography." Note that in the synopsis and throughout the article, first person usage has been changed to third person per journal style.
