Abstract

Objective　To evaluate the accuracy of location and clinical effect of the DSA technique combined with color Doppler ultrasound on the perforator of the anterolateral thigh flap. 　Methods　From July 2017 to June 2019, the application of DSA technique combined with color Doppler ultrasound was used in 154 cases of 160 anterolateral thigh flaps to perform the preoperative perforator and locate the distribution of lateral circumflex femoral artery. The data were used to guide the design of the lobulated flap and the cutting of blood vessels in the operation. The accuracy of localization, the cutting time and survival rate of skin flap was analyzed statistically.　Results　The perforator of the skin flaps in our group were located through DSA combined with color Doppler ultrasound before operation. The location and distribution of perforator during operation were no difference from the pre-operation.154 cases of 160 skin flaps were all successfully survived, and the cutting time of skin flap was 10~60 min, with an average of 25 min．Conclusions　DSA technique combined with color Doppler ultrasound in the location of the perforating branch of the anterolateral thigh flap can be used selectively in clinic. It can seek the skin flap perforator during the operation accurately and effectively, reduce the donor site damage and shorten the operation time.
