Hc. Chen et al., CROSS-LEG FREE FLAPS FOR DIFFICULT CASES OF LEG DEFECTS - INDICATIONS, PITFALLS, AND LONG-TERM RESULTS, The journal of trauma, injury, infection, and critical care, 43(3), 1997, pp. 486-491
Background: Cross-leg free flaps have been described for reconstructio
n of leg defects in cases of trauma with no suitable recipient vessels
in the vicinity of the defect, The pitfalls, however, have not been w
ell documented in the literature, The technique of transfer and the le
ngth of time required before pedicle division depend on the nature of
the flap and the contact surface. Methods: Eight cross-leg free flap r
econstructions were performed on seven patients between 1986 and 1993,
These included three latissimus dorsi muscle flaps, three fibula oste
omyocutaneous flaps, one tensor fascia lata myocutaneous flap, and one
posterolateral thigh flap, The important technical considerations are
outlined. Results: One latissimus dorsi flap failed, whereas the rest
of the flaps completely survived, The morbidity of the recipient and
donor sites are listed. Conclusion: We conclude that the technique off
ers the possibility of salvaging limbs that are, otherwise, nonreconst
ructable, It is useful for young patients, When the flap is long, it c
an function as a nutrient flap for the distal limb even though the ped
icle has been divided, It is a backup procedure in an urgent situation
of re-exploration in which reestablishment of circulation should take
place as soon as possible.
