Latissimus Dorsi Muscle Flap Reconstruction

A popular and effective method of reconstructing the breast after mastectomy is through the use of latissimus dorsi muscle flap reconstruction. Also known as a LAT flap, this is considered a muscle-transfer technique because it uses muscle tissue from the back to create a natural-looking and feeling breast mound.

What is Latissimus Dorsi Muscle Flap (LAT Flap) Reconstruction?

The latissimus dorsi muscle, commonly referred to as the lats, is one of the largest muscles in the human body and is located on either side of the back, extending from the lower back to the upper.

This technique involves transferring a section of the latissimus dorsi muscle to the chest area. By using a flap of this powerful and versatile muscle, surgeons are able to restore shape and volume to the breast while also preserving blood flow and tissue integrity.

Recovery may take several weeks, but the outcome is often a soft, natural-feeling breast that restores both physical appearance and confidence for the patient.

What are the Benefits of Latissimus Dorsi Muscle Flap Reconstruction?

Latissimus dorsi muscle flap breast reconstruction is an advanced surgical method that uses a section of muscle and fat from the patient's back to rebuild the breast following mastectomy. It has all the benefits of flap reconstructions, [Link to Flap Reconstruction] including:

Natural Appearance: Another advantage of this procedure is that it provides a more natural appearance compared to other reconstructive techniques. Because the latissimus dorsi muscle closely resembles the texture and tone of surrounding tissues, it can help restore a more symmetrical and aesthetically pleasing look.
Reduced Risk of Complications: Latissimus dorsi muscle flap reconstruction carries a lower risk of complications compared to some other types of reconstructive surgery. Since the transferred muscle tissue comes from the patient's own body, there is less chance of rejection or infection.
Long-lasting Results: The results of LAT flap reconstruction are usually long-lasting, providing patients with lasting improvements in both function and appearance. With proper care and follow-up appointments, patients can enjoy the benefits of this surgery for many years to come.
Simultaneous Breast Reconstruction: In many cases, the latissimus dorsi muscle flap reconstruction procedure can be performed at the same time as the mastectomy so you need fewer surgeries.
Nipple and Areola Reconstruction: During this procedure, the surgeon can recreate the nipple and areola using tattooing or grafting techniques. This helps achieve a more natural appearance and enhances the aesthetic outcome of the procedure.

Who is a Good Candidate for Latissimus Dorsi Muscle Flap Reconstruction?

Most women who opt for autologous breast reconstruction (that is, using their own tissue) are eligible for LAT breast reconstruction because it uses the patient’s own skin, fat, and muscle to create a new breast.

Current Health: Autologous breast reconstruction is offered to all healthy patients. However, if you are a current smoker or have multiple medical issues, you must understand that your risk of complications may be higher. Efforts will be made to minimize risk in collaboration with your doctor.
Treatment Needs: This is a good option for women with small or medium-sized breasts. Most thin women require minimal volume for breast reconstruction, but if a larger reconstruction is desired, the latissimus dorsi muscle may be supplemented, often with an implant.
Non-Smokers: Smoking can impair blood flow and increase the risk of complications during surgery and recovery. Candidates for latissimus dorsi muscle flap reconstruction are typically advised to quit smoking prior to undergoing the procedure.
Past Surgeries: Prior abdominal surgeries, such as cesarean section or laparoscopic procedures, can sometimes cause problems for flaps harvested from the abdomen. Using the latissimus dorsi muscle avoids this complication.
Personal Preferences: LAT flap reconstruction uses the patient's own tissues rather than synthetic implants. This can be appealing to patients who prefer an all-natural approach to breast reconstruction.

It's important for candidates for latissimus dorsi muscle flap reconstruction to have realistic expectations about the outcomes of the procedure. While this surgery can provide significant improvements in both appearance and function, it may not always achieve perfection.

What Should I Expect From My Surgery?

In a LAT flap procedure, surgeons create an incision in the back near the shoulder blade and take skin, fat, blood vessels, and a section of the latissimus muscle and move it under your skin to your chest to reconstruct the breast. The blood vessels of the flap remain connected to their original blood supply in the armpit. The latissimus muscle is shifted from the back to the front of the body, often eliminating the need for microsurgery. However, in some cases, surgeons may need to use microsurgery to connect blood vessels from the flap to those in the chest to ensure proper positioning. Your surgeon may insert an implant under the flap to achieve your desired outcome because these flaps can sometimes be thinner than other options. The incision made during LAT flap surgery results in a scar on the back, usually positioned to be covered by a bra strap.

Before Surgery

Before your surgery, you'll have a meeting with your surgical team to go over the details of your operation. This is a great opportunity to ask any questions you may have and ensure you fully understand the procedure, its purpose, associated risks, and any alternative treatments available.

Your healthcare team will provide you with specific instructions to prepare for surgery, which may include:

Informing your healthcare team about any medications, vitamins, or supplements you're currently taking, as certain substances may interfere with the surgery.
Stopping certain medications, such as aspirin or other blood-thinners, as advised by your healthcare team.
Following guidelines regarding fasting before surgery, which may involve refraining from eating for several hours beforehand and only drinking liquids up to a certain time.
Planning for post-surgery arrangements, such as whether you'll need to stay in the hospital overnight or go home the same day. Arrange for transportation if you're discharged the same day and prepare a bag with essentials for your hospital stay, including toiletries and items for comfort and entertainment.

During Surgery (Procedure Overview)

It's not unusual to have latissimus dorsi muscle flap reconstruction at the same time as a mastectomy. This is major surgery that will normally involve staying in the hospital for 2 to 5 nights. The procedure can vary based on your personal circumstances and your doctor's methods.

You'll be asked to change into a gown.
An IV (intravenous) line will be inserted into your arm or hand to give you medication that will help you relax and put you to sleep during surgery.
Your vital signs, like heart rate and blood pressure, will be monitored throughout the surgery.
The skin around the surgical area will be cleaned with a sterile solution.
Your surgeon will make an incision in your mid-back on the same side as your mastectomy, normally in a position where the scar will be covered by your bra strap.
A single flap of muscle with its skin, fat, and blood vessels will be moved from your back, underneath the skin, to your chest.
If necessary, your surgeon will transfer carefully attach the blood vessels from the flap to blood vessels in your chest.
Your surgeon will then reconstruct the shape of the breast.
Drainage tubes may be inserted into the area.
The incisions will be closed with stitches or adhesive strips and a sterile bandage or dressing will be applied over both the surgery sites.

After Surgery & Recovery

During your hospital stay, you'll be taken to the recovery room after the procedure. There, you'll be closely monitored until your vital signs like blood pressure, pulse, and breathing are stable, and you're awake and alert. Once you're stable, you'll be moved to your hospital room.

Typically, you'll stay in the hospital for 2 to 5 days after this procedure.

Once you're home, it's important to keep the surgical area clean and dry, following your doctor's instructions. You'll also need to care for the drainage tubes, which are usually removed after about 2 weeks at your first follow-up exam.

You may experience some pain, which can vary depending on the surgery. Your healthcare team will recommend pain relievers, but be cautious about taking aspirin or certain other pain medicines that may increase the risk of bleeding.

You can typically resume normal activities in a few weeks, but you should avoid strenuous activities in the meantime. Your surgeon will advise you on when you can drive again and return to work.

If you're having difficulty coping with your recovery, you may find it helpful to speak to your loved ones or to join a support group for assistance. This can help you cope with the emotional aspects of undergoing this type of surgery.
