Abstract
Aneurysms are circumscribed dilatations of the arterial vessel wall, located at gaps in the muscular layer (medial defects). The endothelial layer and the adventitia, forming the aneurysm dilatation, may both show degeneration and thinning. Aneurysms can be found in many human arteries but are by far most frequently encountered in intracranial vessels. This is most probably because intracranial arteries are thinner and stiffer walled compared with extracranial arteries of similar size. Intracranial aneurysms are mostly located at vascular bifurcations, even if one of the two branching vessels escapes angiographic visualization.
We would like to dedicate this chapter to the physicians and their familieSy who often have to sacrifice their scarce spare time in order to treat these serious and potentially life-threatening disorders of the human vascular system.
