Abstract

Arteriovenous malformation (AVM) is a type of congenital vascular malformations (CVM) that result from birth defects involving the vessels of both arterial and venous origins, resulting in direct communications between the different size vessels or a meshwork of primitive reticular networks of dysplastic minute vessels which have failed to mature to become “capillary” vessels termed “nidus.” As described in previous chapter, development of AVM attributes to an embryonal defect in the earlier stage of the angiogenesis than other forms of CVM. Therefore, the components of AVMs are more primitive than other types of CVM. In other words, it means AVM has higher potential to change after birth during growth of the patients. These lesions are defined by shunting of high-velocity, low-resistance flow from the arterial vasculature into the venous system in a variety of fistulous conditions.
