[Abdominal hernias resulting from abdominal flap harvest].

The anatomic characteristics of the anterior abdominal wall allow the harvesting of various types of flaps, some of them with considerable volume. These flaps are used mainly for reconstruction of the female breast, thoracic wall, and perineal or ilioinguinal region. Even though general donor site morbidity is low, hernias and "bulging" can occur due to the harvest of muscle and fascia, which leads to a weakening of the abdominal wall. Hernias and bulging appear mostly after harvest of classic flap types, which include removal of the rectus abdominis muscle. Further refinements of these flaps, i.e. microvascular flaps, in particular perforator flaps, lead to a marked reduction in donor site morbidity. In the following overview, the problem of abdominal wall weakening as a result of flap harvest is discussed and possible therapeutic options are elucidated.
