Autologous breast reconstruction with the extended latissimus dorsi flap

The extended latissimus dorsi myocutaneous flap can provide autogenous tissue replacement of breast volume without an implant. Nevertheless, experience with the extended latissimus dorsi flap for breast reconstruction is relatively limited. In this study, the authors evaluated their experience with the extended latissimus dorsi flap for breast reconstruction to better understand its indications, limitations, complications, and clinical outcomes. All patients who underwent breast reconstruction with extended latissimus dorsi flaps at the authors' institution between January of 1990 and December of 2000 were reviewed. During the study period, 75 extended latissimus dorsi flap breast reconstructions were performed in 67 patients. Bilateral breast reconstructions were performed in eight patients, and 59 patients underwent unilateral breast reconstruction. There were 45 immediate and 30 delayed reconstructions. Mean patient age was 51.5 years. Mean body mass index was 31.8 kg/m2. Flap complications developed in 21 of 75 flaps (28.0 percent), and donor-site complications developed in 29 of 75 donor sites (38.7 percent). Mastectomy skin flap necrosis (17.3 percent) and donor-site seroma (25.3 percent) were found to be the most common complications. There were no flap losses. Patients aged 65 years or older had higher odds of developing flap complications compared with those 45 years or younger (p = 0.03). Patients with size D reconstructed breasts had significantly higher odds of flap complications compared with those with size A or B reconstructed breasts (p = 0.05). Obesity (body mass index greater than or equal to 30 kg/m2) was associated with a 2.15-fold increase in the odds of developing donor-site complications compared with patients with a body mass index less than 30 kg/m2 (p = 0.01). No other studied factors had a significant relationship with flap or donor-site complications. In most patients, the extended latissimus dorsi flap alone, without an implant, can provide good to excellent autologous reconstruction of small to medium sized breasts. In selected patients, larger breasts may be reconstructed with the extended latissimus dorsi flap alone. This flap's main disadvantage is donor-site morbidity with prolonged drainage and risk of seroma. Patients who are obese are at higher risk of developing these donor-site complications. In conclusion, the extended latissimus dorsi flap is a reliable method for total autologous breast reconstruction in most patients and should be considered more often as a primary choice for breast reconstruction.     

Breast reconstruction without an implant: results and complications using an extended latissimus dorsi flap

The results of 55 breast reconstructions using an extended latissimus dorsi myocutaneous flap without an implant are reported. A method for preoperatively estimating the flap volume, operative details, and a technique for insetting the flap are reviewed. Good, fair, and poor results were achieved in 69, 24, and 7 percent of patients, respectively. Examples are illustrated. The poor results were all due to major complications and are analyzed in detail. Significant complications affecting the end result occurred in 14.5 percent of patients, and nonsignificant and minor complications occurred in 33 percent. Flap volume is shown to be fairly accurately predictable. Seventy percent of flaps had a volume in excess of 400 cc. The reconstructed volume, cosmetic results, and complication rates are compared with those of other reported series. Good results can be achieved with this method, quite comparable to other methods, and with similar complication rates, but without the problems associated with the use of a prosthetic implant.     

Delayed breast reconstruction with a pedicled contralateral latissimus dorsi musculocutaneous flap.

Use of the pedicled contralateral latissimus dorsi musculocutaneous flap is a safe and valuable option in delayed breast reconstruction. This flap also can create an anterior axillary fold by including fat from the lumbosacral fascia.     

Sensitivity of breasts reconstructed with the autologous latissimus dorsi flap

The purpose of this study was to measure, both objectively and subjectively, the sensitivity of breasts reconstructed with the autologous latissimus dorsi flap and to compare these results with those of other reconstruction techniques, especially the transverse rectus abdominis myocutaneous flap. The study population included 50 patients with autologous latissimus dorsi flap breast reconstruction; these patients had an average age of 51 years and an average follow-up of 27 months. Patients answered a seven-item questionnaire that attempted to define the sensitivity of the reconstructed and opposite breasts. This sensitivity was then measured objectively using standard techniques for heat, cold, and tactile sensations. After statistical analysis, these results were compared with those published for other reconstruction techniques. Overall results were comparable or superior to those published for other techniques for autologous breast reconstruction. A total of 56 percent of patients had fine or very fine sensitivity, but 70 percent deemed this sensitivity to be less than that of the opposite breast. A total of 94 percent of patients perceived the reconstructed breast as integral to their body image. The superior medial part of the breast had the greatest sensitivity, both objectively and subjectively. Autologous latissimus dorsi breast reconstruction, a good technique with excellent aesthetic results, affords satisfactory sensitivity. This is yet another advantage of the technique.     

Lumbar hernia after latissimus dorsi flap

The authors present what they believe to be the first recorded case of a lumbar hernia following latissimus dorsi myocutaneous flap procedure. The authors discuss the diagnosis by physical examination and x-ray confirmation, pointing out the importance of not mistaking the hernia for a seroma. Suggestions for avoiding the problem are given, relating primarily to preservation of the fascia underlying the distal latissimus aponeurosis.     

Chest-wall reconstruction by contralateral latissimus dorsi musculocutaneous flap

Reconstruction of chest wall and axilla are performed in 11 patients using a contralateral latissimus dorsi musculocutaneous flap. The entire lattisimus dorsi muscle, including the fascial portion, safely carried an island of skin from the area of the lumbodorsal fascia to the contralateral axilla. The flap was transposed to the defect through a tunnel between the pectoralis major and minor muscles. Most patients who needed reconstruction of the chest wall and axilla had compromised ipsilateral vasculature that prohibited its use in a pedicled flap but had an intact contralateral chest wall, axilla, and thoracodorsal vessels. Therefore, this procedure was performed easily in comparison with a free flap or pedicled omental flap. This is a new, valuable application for the versatile latissimus dorsi musculocutaneous flap.
