The oblique branch trap in the harvest of the anterolateral thigh myocutaneous flap.

چکیده
A 67-year-old man with squamous cell carcinoma underwent reconstruction with a free anterolateral thigh myocutaneous flap. Unroofing the skin perforators found that the skin perforators originated from the oblique branch of the lateral circumflex femoral artery with no connections with the descending branch. Thus, the flap was harvested based on the oblique branch, leaving the descending branch in situ. Reconstruction was completed uneventfully and he had an excellent outcome at 1-year follow-up. The anterolateral thigh myocutaneous flap was reputed to be a technically easy flap to harvest. The perforators supplying the skin were visualized and a block of muscle incorporating the perforators harvested with the descending branch of the lateral circumflex femoral artery as the pedicle of the flap. However, not infrequently with this approach, the flap thus harvested has a well-perfused muscle component, whereas the skin component was not viable. This situation is explained anatomically by the potential occurrence of an alternative pedicle that supplies the anterolateral thigh flap, called the oblique branch of the lateral circumflex femoral artery. Our case presented here was a "classic" intraoperative finding of this potential trap and the importance of defining the anatomy before committing oneself to the harvest by unroofing all the skin perforators was emphasized.

Alternative vascular pedicle of the anterolateral thigh flap: the oblique branch of the lateral circumflex femoral artery.
BACKGROUND The anterolateral thigh flap is known for variations of its vascular pedicle. This is a prospective intraoperative analysis of the vascular anatomy of the lateral thigh that focuses on clinically important variations that impact flap harvest. METHODS Eighty-nine consecutive anterolateral thigh flaps were harvested. A detailed intraoperative analysis was performed of the vasculature...

We report two cases of poliomyelitis in which an anterolateral thigh myocutaneous free flap was harvested from the paralytic limb for oral reconstruction. We observed a decrease in the pedicle diameter of the anterolateral thigh flap, but the blood supply to the skin paddle was adequate.
متن کاملReconstruction of Wide-apart Double Defect Using a Branch-based Chimeric Anterolateral Thigh Flap
SUMMARY Wide-apart double defect in head and neck region is rare and difficult to reconstruct at one time. Double free flaps are normally used for this scenario and often tedious and technically complicated. This study presented a technique using branch-based anterolateral thigh free flap to simultaneously reconstruct the 2 defects separated wide apart. The concept, indications, surgical techni...
