ABSTRACT
OBJECTIVE@#To investigate the effectiveness of dorsal perforator flap of cross-finger proper digital artery in the treatment of finger soft tissue defect caused by high-pressure injection injury.@*METHODS@#Between July 2011 and June 2020, 14 cases of finger soft tissue defect caused by high-pressure injection injury were repaired with dorsal perforator flap of cross-finger proper digital artery. All patients were male, with a mean age of 36 years (range, 22-56 years). The defects were located on the index finger in 8 cases, middle finger in 4 cases, and ring finger in 2 cases. The causes of injury include 8 cases of emulsion paint injection, 4 cases of oil paint injection, and 2 cases of cement injection. The time from injury to debridement was 2-8 hours, with a mean time of 4.5 hours. The soft tissue defects sized from 4.0 cm×1.2 cm to 6.0 cm×2.0 cm. The flaps sized from 4.5 cm×1.5 cm to 6.5 cm×2.5 cm. The donor site of the flap was repaired with skin graft. The pedicle was cut off at 3 weeks after operation, and followed by functional exercise.@*RESULTS@#All flaps and skin grafts at donor sites survived, and the wounds healed by first intention. Twelve patients were followed-up 16-38 months (mean, 22.6 months). The texture and appearance of all flaps were satisfactory. The color and texture of the flaps were similar to those of the surrounding tissues. The two-point discrimination of the flap was 10-12 mm, with a mean of 11.5 mm. There were different degrees of cold intolerance at the end of the affected fingers. At last follow-up, the finger function was evaluated according to the Upper Extremity Functional Evaluation Standard set up by Hand Surgery Branch of Chinese Medical Association, 3 cases were excellent, 8 cases were good, and 1 case was poor.@*CONCLUSION@#The dorsal perforator flap of cross-finger proper digital artery can effectively repair finger soft tissue defect caused by high-pressure injection injury. The operation was simple, and the appearance and function of the finger recover well.

This is a report of a complex defects in the right upper extremity treated in the Department of Hand and Microsurgery, 521 Hospital of Norinco Group, in October 2016. The patient received multi-transfers of flaps for one-stage reconstruction, including a double-paddled ALTPF and a compound flap of the great toe and the second toe. Vascular compromises occurred in flaps on the 2nd day after surgery. All the flaps were rescued and survived completely after surgical exploration. Followed-up at 3 year after surgery showed that the appearance and function of the affected limb recovered well. The flexion and extension of elbow and wrist were normal. The pinch function of the reconstructed thumb and index finger recovered well.
ABSTRACT
Objective To explore the clinical effects of sequential flap of thigh perforator for closure of the anterolateral thigh free flap donor site.Methods From March,2014 to May,2015,8 consecutive patients underwent elective anterolateral thigh free flap reconstruction for limb soft tissue defect.To design a sequential flap of thigh perforator to achieve primary closure of the anterolateral thigh free flap donor site.The area of anterolateral thigh free flap ranged from 9.0 cm×6.0 cm to 20.0 cm×1 1.0 cm,respectively.The area of thigh perforator flap ranged from 7.0 cm×3.0 cm to 12.0 cm×7.0 cm.Results All flaps healed uneventfully.Distal skin flap necrosis appeared in 1 flap which was healed after local transposition flap.All the patients were followed up for 1 to 6 months,with mean time of 4 months.The color,texture and appearance of flaps were satisfactory.Conclusion Sequential flap of thigh perforator,with reliable blood supply and constant position,represents an ideal model to close the anterolateral thigh free flap donor site of small defect.
