Abstract

Abstract:

Objective　To explore the application and clinical effects of anterolateral thigh (ALT) perforator flap with

turbocharging technique of anteromedial thigh perforator in repairing large area defects. Methods　A retrospective case-series

study was conducted to analyze the clinical data of 9 patients with complex wounds of limbs from March 2014 to December

2021. There were 6 males and 3 females, aged 23-68 years. The defect area ranged from 20 cm×12 cm to 25 cm×13 cm. The

flap area was roughly equal or slightly larger than the wound area. Extended ALT perforator turbocharged flaps were done in 9

patients. An additional microvascular augmentation of the distal or descending branch of the lateral circumflex artery (LCFA)

with the sizable AMT perforator was performed during the operation to augment the viability of the ALT flap. The ratio of flap

width and thigh circumference was measured (F/T ratio). Results　The extended ALT turbocharged flaps survived without

peripheral necrosis or serious complications. The average F/T ratio was 0.319 (0.302~0.341). The patients' average flaps width

and thigh circumference were 13.9 cm and 43.6 cm respectively. The mean follow-up was 10.2 months and no complications

were recorded. Conclusion　ALT perforator flap with turbocharging technique of AMT perforator may be an alternative choice

when the flap area is too large, especially in patients whose F/T ratio is greater than 0.3. However, the reliability of this ratio still

needs further investigation.
