Successful umbilicus salvage following concurrent infraumbilical single-port myomectomy and free transverse rectus abdominis myocutaneous flap elevation: a case report

Performing a concurrent gynecologic operation and mastectomy with immediate breast reconstruction using a free transverse rectus abdominis myocutaneous flap may increase the risk of complications such as umbilical necrosis due to vascular compromise. Imaging studies such as preoperative computed tomography angiography and intraoperative indocyanine green testing can provide information regarding the umbilical blood supply, facilitating decision-making for pedicle selection. Therefore, in situations where a coordinated operation is unavoidable, a thorough preoperative and intraoperative evaluation of the umbilical blood supply is recommended to avoid complications.

TRAM flap breast reconstruction

The transverse rectus abdominis myocutaneous (TRAM) flap retains a prominent role in contemporary breast reconstruction surgery. This chapter reviews the origins and anatomy of the TRAM flap, both as a pedicled and free tissue transfer. Patient selection and flap planning are examined in the context of immediate and secondary breast reconstruction with attention to oncological considerations and patient risk factors. The elements influencing choice between a pedicled or free flap are discussed and some guidelines to decision-making for abdominal based breast reconstruction are offered. Detailed descriptions of surgical technique and perioperative care follow, illustrated by case examples.

Application of Botulinum Neurotoxin Injections in TRAM Flap for Breast Reconstruction: Intramuscular Neural Arborization of the Rectus Abdominis Muscle

Breast reconstruction after mastectomy is commonly performed using transverse rectus abdominis myocutaneous (TRAM) flap. Previous studies have demonstrated that botulinum neurotoxin injections in TRAM flap surgeries lower the risk of necrosis and allow further expansion of arterial cross-sectional diameters. The study was designed to determine the ideal injection points for botulinum neurotoxin injection by exploring the arborization patterns of the intramuscular nerves of the rectus abdominis muscle. A modified Sihler’s method was performed on 16 rectus abdominis muscle specimens. Arborization of the intramuscular nerves was determined based on the most prominent point of the xyphoid process to the pubic crest. All 16 rectus abdominis muscle specimens were divided into four muscle bellies by the tendinous portion. The arborized portions of the muscles were located on the 5–15%, 25–35%, 45–55%, and 70–80% sections of the 1st, 2nd, 3rd, and 4th muscle bellies, respectively. The tendinous portion was located at the 15–20%, 35–40%, 55–60%, and 90–100% sections. These results suggest that botulinum neurotoxin injections into the rectus abdominis muscles should be performed in specific sections.

Response to ‘Australia's contribution to the free abdominoplasty flap in breast reconstruction’

Perhaps few realise that the development of what became known as the free transverse rectus abdominis myocutaneous (TRAM) flap was a race involving not one but two surgical teams, one in Sydney and the other, with the aid of the Australian Richard Hamilton, in Sweden
