New methods and technologies in the field of perforator flap studies / 中华整形外科杂志

ABSTRACT

A large number of innovative and new technologies and method in the field of perforator flap were proposed with the hard work of many experts and surgeons. This paper briefly reviewed the following items including the discovery of the perforator flap and its enlightenment to us, three-dimensional visualized anatomy, angiosome and perforasome theories, pre-operative perforator detection techniques, techniques for evaluation of the flap vascular perfusion, the concept of freestyle perforator flap, chimeric flap, flow-through flap technique, new designs of pedicle perforator flap, particularly the propeller and keystone flaps, supramicrosurgery, superthin flap, microdissected thin perforator flap, and microvascular breast reconstruction and lymph node transfer for postmastectomy lymphedema patients. These new technologies and method have greatly improved our understanding of flap surgery and promote the development of the reconstructive surgery. The traditional research focused on investigating the anatomic features of a single flap and strategies for the reconstruction of different defects and organs. Nowadays, the treatment scope of reconstructive surgery is more extensive and has developed to repair various refractory wounds following trauma and oncological resection, nerve injuries, and to reconstruct defect and organ by using the vascularized composite allotransplantation. Researches on the upper limb lymphedema after breast cancer surgery have been highly valued recently. It can be expected that the direction of reconstructive surgery would be transformed from the improvement of theraputic modalities to concentrating on the treatment of diseases, and this undoubtedly conforms to the essence of medicine. The research of perforator flaps will be directed to more precise, minimally invasive, and individualized according to the requirements of evidence-based medicine.
