Overview
The catastrophic potential of intracranial aneurysms, arteriovenous malformations (AVMs), and arteriovenous fistulas (AVFs) and the complexity of their pathogenesis have made them the subject of intense interest and study over the past 80 years. Advances in the ability to treat these lesions have been paralleled by rigorous research on their pathophysiology. An increase in the longevity of the population over the past century and improvements in imaging techniques contribute to more frequent encounters with these lesions by neurosurgeons and interventionists. Despite numerous clinical and laboratory research projects studying the pathophysiology of these lesions, much remains to be learned. In this chapter, we will discuss the pathophysiology of various types of intracranial aneurysms, as well as AVMs and AVFs.
