Choke vessels serves as bridges connecting adjacent vascular territories in perforator flaps and play a significant role in im-proving the survival rate of perforator flaps.Currently,research on how to enhance the survival rate of perforator flaps focuses on increasing the blood supply of choke vessels by various measures.By reviewing the research progress of choke vessels in perforator flaps,we analyzes the impact of different intervention measures on choke vessels,and aims to provide reference directions for future research on improving the survival rate of perforator flaps.
