Abstract:
Objective:To explore the clinical value of modified infrared thermal imaging assisted design of peroneal artery perforator propeller flap.Methods:From March 2019 to May 2021, tourniquet-reperfusion augmented thermal imaging method (TRATIM) was used to locate the perforating vessels in 14 patients for surgery or peroneal artery perforator propeller flap. The sensitivity, positive predictive value and detection time were calculated and compared with the perforating vessels located by color Doppler ultrasound(CDU), P<0.05 is statistially significant. Results:After operation, 13 flaps survived completely, but 1 flap with distal surface necrosis and healed after dressing change. Only one linear scar was left in 12 cases, and 2 cases healed well by skin grafts. Followed-up for 6-13 months, and showed that the colour and texture of the flaps were similar to the surrounding skin, without obvious swelling. The sensitivity of TRATIM and CDU in location of peral perforator vessels were 88.0% and 92.0%, respectively, and the positive predictive value was 93.6% and 95.8%, with no statistical difference between TRATIM and CDU( P>0.05). The time of positioning perforator was (3.71±0.80) min for TRATIM and(16.21±4.97) min for CDU, There was significant difference between TRATIM and CDU( P<0.01). Conclusion:With TRATIM, a surgeon can locate the peroneal perforator vessels simply, quickly and accurately, and help in design more accurate peroneal artery perforator propeller flap.
