AB  - BACKGROUND: During free-tissue transfer for scalp reconstruction, pedicle 
      lengthening may be required when finding a recipient vessel is difficult because 
      of defects from previous surgery. Arteriovenous (AV) bundle interposition 
      grafting is a good option. This study compared 2 sequences of AV bundle 
      interposition grafting when flap pedicle lengthening is needed. METHODS: Two 
      anastomosis methods were used. In the recipient lengthening type (R type), the 
      flap was harvested and the AV bundle was harvested from a donor vessel for 
      lengthening. In the flap lengthening type (F type), the flap was harvested first. 
      Next, in contrast to that in the R type method, the authors performed anastomosis 
      with a flap pedicle and bundle before the AV bundle was harvested. RESULTS: The 
      mean flap pedicle length was 8.75 cm (range, 5-11 cm). The AV bundle had a mean 
      length of 9.25 cm (range, 6-13 cm), meaning that 13 cm of additional pedicle 
      length can be added. The mean length of the extended vascular pedicle was 18 cm 
      (range, 14-23 cm). CONCLUSION: This study compared the results of F type and R 
      type AV bundle interposition grafting. The F type allowed easy monitoring of the 
      anastomosis of the flap pedicle and ensured flap stability by reducing continuous 
      ischemic time. Finally, this study confirmed the efficacy and safety of the AV 
      bundle interposition graft in scalp reconstruction.
