【摘要】 随着显微血管技术的发展,穿支皮瓣逐渐成为组织缺损重建的首选方法之一。穿支皮瓣供血血管管径细、血管蒂长、血管走行及位置变异大,这就需要临床医生采用术前血管定位技术对穿支血管的解剖结构进行系统评估,从而设计合适的穿支皮瓣。本文就穿支皮瓣的特点及种类,术前定位技术在穿支皮瓣中的研究进展及存在的主要问题作一综述。更多还原

【Abstract】 With the development of microvascular technology, perforator flaps have gradually become a good alternative for reconstruction of tissue defects. However, the major limitations of perforator flaps include uncertainty in predicting anatomical location of perforators and high variability in perforator size and course, which require preoperative localization techniques. Recently, as one of the preoperative localization techniques, computed tomography angiography was used to determine the number, size, course, and exact emerging point of perforator flaps. Clinicians can reduce surgical complications and shorten operative time by using computed tomography angiography. However, only several studies reported clinical applications of computed tomography angiography. This article reviews characteristics, classification, and preoperative location techniques for perforator flaps and its problems.更多还原
