title: The free latissimus dorsi flap revisited: a primary option for coverage of wide recurrent lumbosacral defects.
abstract: In comparison with other regions of the trunk, defects located in the lumbosacral region are infrequent. However, these particular lesions sometimes present difficulties in reconstruction, arising from the quality of the surrounding tissue and the width of the defects. In this area, the skin adheres strongly to subcutaneous tissue and is difficult to mobilize. Attempts to perform local or regional flaps for covering defects of this area often end in necrosis of the flaps, with subsequent risk of infection and unstable wounds. The consequence is larger defects and the need for a wide, tension-free coverage, which can be performed after a wide debridement. The authors report on 10 patients presenting with wide, recurrent (and in some cases, infected) defects of the lumbosacral region, after already having undergone several reconstructive local or regional operations. In all cases, the authors harvested a free latissimus dorsi flap, lengthening the pedicle by means of an arteriovenous suralis loop connected to the thoracodorsal vessels (lumbar defect) or the femoral vessels (sacral defect). The procedure, already described in the past by others, has been revisited by the authors' group and used as the technique of choice in selected cases, that is, in the presence of wide, recurrent, and infected lesions; radiation; and scarring injuries. The authors thus obtained stable coverage with well-vascularized tissue and were able to save the patients any further operations. The authors suggest, therefore, that this procedure can be used in cases of wide and recurrent defects where other conventional procedures have failed. Advantages, disadvantages, and technical features of the method used are discussed in this article.
