Pedicle perforator flaps and keystone perforator island flaps are additional tools for reconstructive surgeons. Advances in understanding of vascular anatomy, the dynamic nature of perforator perfusion, inter-perforator flow and the hot-spot principle have led to reconstructive techniques that allow innovative autologous tissue transfer while limiting donor site morbidity. Further modifications of the pedicle perforator flap have led to a multitude of freestyle pedicle perforator flap options, as well as freestyle free flaps for soft tissue reconstruction. Modifications in the keystone perforator island flap have increased the degrees of freedom for soft tissue coverage of large defects, with reliable and aesthetically pleasing results.
带蒂穿支皮瓣和关键穿支岛状皮瓣是重建外科医生的额外工具。对血管解剖、穿支灌注的动态特性、穿支间血流以及热点原理的深入理解，催生了一些重建技术，这些技术能够在限制供区并发症的同时实现创新的自体组织移植。带蒂穿支皮瓣的进一步改良产生了多种自由式带蒂穿支皮瓣选项，以及用于软组织重建的自由式游离皮瓣。关键穿支岛状皮瓣的改良增加了大面积缺损软组织覆盖的自由度，效果可靠且美观。
