In a TRAM Flap procedure, tissue is taken from the lower abdominal area and used to
help shape the breast. Skin, fat, blood vessels and at least one muscle from the abdomen are moved from the abdomen to the chest.
There are two types of TRAM flaps: Pedicle Flap and
Free Flap.
Pedicle Flap
In a Pedicle Flap procedure, skin, fat and muscle are removed from your lower abdominal area and used to reconstruct your breast.
The muscle, which carries the blood vessels from your lower abdomen area, remains attached to the original blood supply and is
tunneled under your skin to the breast region.

In addition to the potential advantages and disadvantages listed on the Autologous Breast Reconstruction
page, other potential advantages and disadvantages of TRAM Pedicle Flap are also outlined here.
Potential Advantages | Potential Disadvantages
- Less time needed in surgery versus some other autologous
reconstructions, i.e. DIEP and gluteal
- Less risk of your body rejecting the tissue and less risk of scar tissue forming
- Results in tightening of the lower abdomen skin – similar to a tummy tuck
- May decrease the strength of the abdomen
- Risk of an abdominal hernia occurring
- May affect mobility and range of motion
Free Flap
In a Free Flap procedure, skin, fat and muscle are removed from the lower abdominal area and moved up to the chest in
order to reconstruct your breast. Blood vessels attached to these tissues are also removed from your lower abdomen area
and are then reattached to the existing blood vessels in your chest.

Potential Advantages | Potential Disadvantages
- Less risk of your body rejecting the tissue and less risk of scar tissue forming
- Results in tightening of the lower abdomen skin - similar to a tummy tuck
- May decrease the strength of the abdomen
- Risk of an abdominal hernia occurring
- Microsurgery to connect blood vessels requires extra time in surgery
- Complications associated with microsurgery may result in tissue not surviving when moved to the breast
