approached with care, and either neovascularization across the flap should be confirmed or the main vascular pedicle should be left intact. We report a case of the total loss of a flap after a secondary operation was performed 18 months after successful reconstruction using a latissimus dorsi muscle flap. There is controversy concerning flap neovascularization, and many factors can compromise flap vascularity including the flap itself, patient comorbidities, and the wound condition. Given these risks, additional procedures affecting the flap should be performed with considerable care, with attention paid to flap vascularity.
