Abstract:
Objective:To explore the clinical effect of bilobate anterolateral thigh flaps with turbocharging technique in repairing limb wounds.Methods:A retrospective case series study was conducted to analyze the clinical data of 29 patients with complex wounds of limbs admitted to Ruihua Hospital Affiliated to Soochow University from March 2014 to July 2019. There were 26 males and 3 females, aged 22-60 years [(41.9±11.1)years]. A total of 24 patients had single-wounds with the dimension of 12 cm×10 cm to 38 cm×27 cm, and 5 patients had two adjacent and discontinuous wounds with the area from 7 cm×4 cm to 13 cm×9 cm. The bilobate anterolateral thigh flaps with turbocharging technique were used. All the donor sites were directly sutured by primary closure. Routine treatment was given after operation. The origin artery of perforators, time of flap harvesting and operation time were recorded. The survival of the flap, healing of the donor area, long-term shape of the flap and donor area, sensory recovery and complications were observed.Results:All patients were followed up for 6-64 months [(19.0±12.7)months]. A total of 30 bilobed flaps were designed for the 29 patients. The time of flap harvesting ranged from 25 to 60 minutes [(46.6±20.2)minutes]. The operation time was 4-11 hours [(6.4±1.8)hours]. All flaps survived except one piece of a bilobed flap suffered from a vein crisis, which healed well after conservative treatment. These wounds' healing time ranged from 11 to 53 days [(18.5±9.9)days], and all the donor sites healed by first intention. Four patients underwent skin flap thinning operation 4 to 8 months later due to the bloated appearance of flaps. Acceptable cosmetic outcomes, soft and elastic skin, and sensation recovery were achieved at the final follow-up. All patients 'donor area left linear scars. One patient had large scar area, but there was no scar contracture and pain. Two patients had an abnormal sensation in the incision area in the early stage and recovered gradually 3 months later without any other serious complications.Conclusions:Repair of limb wounds with bilobed anterolateral thigh flaps with turbocharged technique can overcome the limitation that the bilobed flap can not be designed if the perforators do not share the same trunk and expand the application scope of the bilobed flaps. The design of bilobate flaps reduces the width of the donor site, which can effectively avoid the complications of the donor site.
