Abstract: The traditional perforator flap can not meet the need of large-area wound repair because of relatively small area. Therefore, trans-zone flap containing multiple perforasomes is increasingly used in wound repair. However, the high resistance of choke vessels in the trans-zone flap caused the insufficient blood supply at the distal end of the trans-zone flap, which may result in flap necrosis. Therefore, the necrosis at the distal end of trans-zone flap has become a difficult problem in the repair of large-area wound. Studying the hemodynamic changes and vascular remodeling of choke vessels has great significance to improve the distal blood supply of trans-zone flap. This paper reviews the researches on the hemodynamics and vascular remodeling mechanism of choke vessels at home and abroad in recent years, in order to make help for reducing the necrosis at the distal end of trans-zone flap.
