Angiosome Origins and Concept
Main Article Content
Abstract
An angiosome is a composite block of tissue fed by a primary source artery. The term angiosome is derived from the Greek words angeion, which means channel, and somite, which means segment or sector of the body derived from soma, body. Angiosomes can be further differentiated into individual skin perforators or into matching venosomes (venous regions) and arteriosomes (arterial territories). The concept of angiosomes plays a pivotal role in surgical procedures involving tissue transplantation and composite flap formation. The secure anatomic borders defined by angiosomes enable the precise identification and isolation of tissues at various layers, facilitating the transplantation of individual components or the creation of composite flaps.
