Internal relationships within axial pattern flaps between the angiosome and perforasome / 中华整形外科杂志

ABSTRACT

The authors reviewed the concepts of the axial pattern flap, angiosome and perforasome, and analyzed the anastomosis and hemodynamic characteristics between the angiosome and the perforasome. Results: (1) Axial pattern flaps can be designed either in the angiosome or in perforasome. The difference is the pedicle and vascular axis. (2) The middle perforator should be the first choice as the pedicle for multi-perforators cross-territory flap, and the axial direction of the flap should be the same as that of the source artery. (3) Avoid as much as possible nutrient large flap with small blood vessels, that is, using a perforating vessel as a pedicle to cross-zone support to an angiosome flap. (4) The position of vascular pedicle and venous drainage is more important than the size and number of blood vessels. It is proposed that the transformation and reconstruction of the axial vascular in the multi-perforated cross zone flap to establish a new blood circulation system is a research hotspot and challenges in the study of anatomy. It is necessary to work closely with the surgeons.
