Objective To provide a comprehensive review for development and existing problems of the perforator flaps. Methods The related home and abroad l iterature concerning perforator flaps was extensively reviewed. Results The perforator flaps are defined as the axial flaps nourished solely by small cutaneous perforating vessels (perforating arteriesand veins), which are exclusively composed of skin and subcutaneous fat. The perforator flaps have the advantages as follows: less injury at donor site, less damage to the contour of the donor site, good reconstruction and appearance of the reci pient site flexible design, and short time of postoperative recovery, which have been widely used in reconstructivesurgery. Conclusion The perforator flaps are the new development of the microsurgery, which usher an era of small axial flaps; However, the controversies of the definition, vascular classification, the nomenclature, and the cl inical appl ication of the perforator flaps still exist, which are therefore the hot spot for future study.
This article reviews Chinese nomenclature of renal replacement therapy and extracorporeal blood purification currently utilized to manage acute kidney injury and other organ dysfunction syndromes in critically ill patients, based on the recent reports of a consensus expert conference of Nomenclature Standardization Initiative Alliance. We provide a detailed description of the performance characteristics of membranes, filters, transmembrane transport of solutes and fluid, flows, and methods of measurement of delivered treatment, common definitions, components, techniques, and operations of the machines and platforms as well as the renal replacement therapy techniques in detail with the relevant technologies, procedures, operations, and recent developments in other extracorporeal therapies, including therapeutic plasma exchange, multiple organ support therapy, liver support, lung support, and blood purification in sepsis. We believe this nomenclature review will serve future use of terminology in publications, research, clinical operations and therapy platforms to enable consistent data collection and comparison.
