Free flap reconstruction of the lower extremity in the elderly

Summary Over a four year period, thirteen patients over the age of 60 (mean 69 years) underwent reconstruction of lower extremity defects with free tissue transfers. Ten latissimus dorsi, one tensor facia lata, and two rectus abdominus free flaps were used. Despite significant risk factors which included previous tobacco use, hypertension, diabetes mellitus, and angiographic vessel abnormalities, ten of thirteen cases had successful outcomes. There was one acute flap failure secondary to arterial thrombosis. Four flaps had delayed healing, with one patient eventually requiring amputation secondary to persistent pain and wound drainage. This experience demonstrates that free flap reconstruction of lower extremity defects in the elderly patient is a reasonable alternative to amputation when other options are limited.From the Section of Plastic and Reconstructive Surgery at the Mayo Clinic and Mayo Foundation, Rochester, Minnesota, USARequests for reprints: J.
