Various Abdominal Flaps for Breast Reconstruction: Pedicled TRAM, Free TRAM, Muscle-sparing TRAM, DIEP, and SIEA Flaps / 영남의대학술지

ABSTRACT

The incidence of breast cancer, the second most prevalent cancer type in South Korea, has increased by 6.8% annually in the lastsix years.The higher number of breast cancer patients has led to an increase in the cases of skin-sparing mastectomies, thereby increasing the need for reconstructive procedures. The reconstruction options include alloplastic techniques such as implant or autologous reconstruction with numerous flaps. The abdominal area is the preferred donorsite for the harvest of autologous tissue for breast reconstruction. Breast reconstruction using abdonimal tissue is commonly accomplished using the transverse rectus abdominis myocutaneous (TRAM) flap. The establishment of microvascular surgery led to the development of the free TRAM flap because of its increased vascularity and decreased rectus abdominis sacrifice. The muscle-sparing TRAM, DIEP, and SIEA flap techniques were later developed in an effort to decrease the abdominal-donor-site morbidity by decreasing the injury to the rectus abdominis muscle and fascia. This article summarizes the various abdominal flaps for breast reconstruction.
