Reverse-supercharged, distally based latissimus dorsi flap for lumbar defect: A case report.
Well-vascularized tissue is required for successful reconstruction of a soft tissue defect in the lumbar region. There are several options for reconstruction; however, controversy exists regarding the optimal technique. Here, we present a case of a lumbar defect following tumor resection in a 75-year-old patient that was repaired using a reverse-supercharged, distally based latissimus dorsi flap. ⋯ The patient was discharged 17 days after the surgery, and no recurrence of the tumor was observed at the 2-year follow-up. We report a case of successful salvage of a distally based latissimus dorsi flap by the reverse-supercharge technique based on a serratus anterior branch. This flap might be a suitable alternative for use in the lumbar region in the case of limited availability of reconstructive choices.

Vascularized composite allotransplantation represents as an emerging field in reconstructive surgery. However, some complications can be associated with the procedure. The authors describe a case of bone infarctions of the bilateral hip joints following the first hand allotransplantation in Taiwan. ⋯ The patient underwent a right hip hemi-arthroplasty with a bipolar prosthesis 3 months later. The patient remained in good health without major complications. These findings indicate that systemic steroids and tacrolimus might be the major predisposing factors for the induction of AVN after hand allotransplantation.

Early soft-tissue coverage is critical for treating traumatic open lower-extremity wounds. As free-flap reconstruction evolves, injuries once thought to be nonreconstructable are being salvaged. Free-tissue transfer is imperative when there is extensive dead space or exposure of vital structures such as bone, tendon, nerves, or blood vessels. ⋯ There have been no long-term complications in either case. Both patients achieved adequate soft-tissue coverage, avoided amputation, and had satisfactory aesthetic and functional outcomes. With appropriate surgical technique and patient selection, the quad-flap technique is promising for reconstructing the lower extremity.

Detecting more number of functional lymphatic vessels is the essential point in lymphaticovenous anastomosis (LVA). The purpose of this prospective study was to elucidate the efficacy of multi-area injection in indocyanine green (ICG) lymphography in LVA. ⋯ By injecting ICG into multiple sites in the affected limbs, we could detect a greater number of functional lymphatic vessels (Ectasis type) during LVA. This could lead to a better surgical result.
