Purpose: The anatomical anomaly of the rectus abdominis muscle and it’s fascia is very rare. No case of the absence of the linea alba below the umbilicus has yet been reported. During breast reconstruction with pedicled TRAM flap, we experienced one case of absence of linea alba.
Methods: The patient was a 38-years old female who underwent immediate breast reconstruction with pedicled TRAM flap after Right modified radical mastectomy in June 2010. While the TRAM flap was being elevated, bilateral twitching of the rectus abdominis muscle occurred when electrocautery was applied, and we found the absence of the linea alba below the umbilicus.
Results: When the rectus abdominis muscle was exposed, the linea alba below the umbilicus was not observed, and the bilateral rectus abdominis muscle was indistinguishably fused in a gross observation. In addition, bilateral twitching of rectus abdominis muscle was simultaneously observed as one muscle unit when electrocautery was applied. As with both rectus abdominis muscles was bluntly dissected with scissors, the scanty fatty tissues were observed between the both rectus muscles, and the bilateral rectus abdominis muscle was easily separated. The flap was transposed into the corresponding defect to make breast mound. Midline fascia was fixed to the posterior rectus sheath to reconstruct smilar anatomic linea alba. Abdominal defect was reinforced by suturing between remaining anterior rectus sheath.
Conclusion: As the unexpected anatomical anomaly may affect the operation outcome, surgeons should be careful when they unexpectedly encounter the anatomical anomaly during an operation. Here, we report a rare case of absence of the linea alba seen at the time of pedicled TRAM flap elevation for breast reconstruction.
