Sentinel lymph node detection and evidence of axillary lymphatic integrity after transaxillary breast augmentation: a prospective study using lymphoscintography

Inadvertent Injection of a Breast Implant During Lymphoscintigraphy

A 34-year-old woman with history of bilateral saline implants, invasive ductal carcinoma of the right breast, and suspicious left breast calcifications was referred for left breast lymphoscintigraphy before bilateral mastectomy. A total of 3.2 mCi of Tc-filtered sulfur colloid was administered with 3 subdermal injections in the superior, lateral, and inferior periareolar left breast in the late afternoon preceding the day of surgery. Imaging identified radiotracer uptake within a dense, circular area deep to the injection sites within the left breast, compatible with implant puncture and radiotracer administration within the indwelling breast implant.

Transaxillary endoscopic breast augmentation with shaped gel implants

BACKGROUND

At its inception, transaxillary breast augmentation was a blind technique associated with complications and unpredictable outcomes. The transaxillary approach now involves electrocautery dissection with direct endoscopic visualization and yields excellent aesthetic outcomes with a concealed scar. Shaped implant devices can be combined with transaxillary augmentation for natural-appearing results that can be individualized to the patient.

OBJECTIVES

The authors sought to improve the results of transaxillary endoscopic breast augmentation by placing shaped gel implants in patients with an indistinct or absent inframammary fold (IMF), who wished to avoid a breast scar.

METHODS

One hundred sixteen Asian women underwent transaxillary endoscopic breast augmentation with electrocautery dissection and were evaluated in a prospective study. A partial retropectoral plane pocket was created in 4 sequential dissection steps with direct endoscopic visualization and careful control of bleeding. Shaped cohesive gel implants were placed to produce smooth, natural-appearing breast mounds and well-defined IMFs.

RESULTS

Patients were monitored for 6 to 24 months after surgery (mean, 10 months; median, 12 months). There were no instances of pneumothorax, instrument-related skin burns, or severe implant deformation due to rotation or displacement of the implants postoperatively. Three of 116 patients (2.6%) experienced Baker 3 unilateral capsular contracture. One patient developed a unilateral hematoma at 3 weeks after surgery.

CONCLUSIONS

Endoscopic breast surgery is associated with shortened recovery times, a reduced need for drainage, and excellent outcomes, including a well-defined and symmetric IMF. This approach, combined with shaped gel implants, can yield natural-appearing results of transaxillary breast augmentation.

Breast augmentation

LEARNING OBJECTIVES

After studying this article, the participant should be able to: 1. Assess patient physical characteristics that influence implant selection. 2. Adopt a system to aid in implant size selection. 3. Become cognizant of the advantages and disadvantages of incision, pocket plane, and implant options. 4. Understand implant positioning concepts and aseptic implant handling methods. 5. Manage untoward postoperative sequelae 6. Understand secondary surgery concepts.

SUMMARY

Breast augmentation is the most commonly performed aesthetic surgical procedure. Choices of incisions, pocket plane, and myriad implant characteristics constitute the basis for surgical planning. Analysis of physical characteristics and inclusion of the patient in implant selection contribute to overall satisfaction and reduce requests for secondary surgery. Technical expertise in implant positioning and aseptic handling helps to prevent capsular contracture, implant malposition, and other shape problems. Despite the need for secondary surgery in some, patient satisfaction is high.

Reoperative transaxillary breast surgery: using the axillary incision to treat augmentation-related complications

BACKGROUND

The axillary incision for breast augmentation has been an option for patients and surgeons for more than 30 years now. Controlled clinical trials have demonstrated that reoperations continue to be significant (15-24% at 3 years) independent of incision choice. The misbelief that the transaxillary approach is not adequate for reoperations inhibits patients' and surgeons' decisions on what incision is best in each case.

METHODS

A retrospective analyses was performed seeking reoperation cases performed from January 2008 to January 2011 that used the same axillary incision as the previous transaxillary augmentation. Data on the cause for the reoperation, time between surgeries, patient age, implant volume, locality of the primary operation, and details regarding the implant type and pocket plane were gathered and analyzed.

RESULTS

A total of 15 patients and 26 breasts needing reoperation were found in this period. The average time between the first surgery and reoperation was 12 months, average patient age was 36 years, and implant volume ranged from 195 to 360 cc, with an average of 283 cc. Six of these patients were previously operated on by the authors and nine were operated on by other surgeons and came to our service seeking revision. Details regarding the implant type and pocket plane are also given. The main causes for reoperation were capsular contracture (26.9%), size change (15.4%), seroma/hematoma (11.5%), infection (11.5%), axillary banding/scarring (11.5%), lower-pole deformity/high-riding (11.5%), asymmetry (7.7%), and rippling/waviness (3.8%).

CONCLUSION

Transaxillary breast augmentation reoperation is feasible if certain principles are followed.

Patient factors affecting operative times for single-incision trans-axillary robotic-assisted (STAR) thyroid lobectomy: does size matter?

BACKGROUND

Single-incision, transaxillary, robotic-assisted (STAR) thyroid lobectomy using a robotic surgical system is a novel surgical approach that is extensively described in Korean patients. Some have suggested that this experience will not translate into the American population because of differing body habitus and because the mean size of the thyroid nodules removed in Korea are <1 cm. We reviewed our experience with STAR thyroid lobectomy.

METHODS

We retrospectively reviewed our prospectively collected data on consecutive cases of STAR thyroid lobectomy performed by a single surgeon. Operative times and patient outcomes were evaluated.

RESULTS

Seventeen operations were performed on 15 patients. Mean total operative time was 219.3 (range, 183-256) minutes. All patients were discharged on postoperative day 1. Postoperative complications were seromas (n = 2) and cellulitis (n = 2). Operative time did not vary with the size or volume of the nodule or gland. The mean nodule diameter was 1.9 (range, 0.5-3.1) cm. The mean nodule volume and thyroid volume were 5.0 (range, 0.1-16.7) cm(3) and 20.7 (range, 11.8-45.8) cm(3), respectively. When stratified by body mass index (range, 19.6-37.8), normal versus overweight or obese, total operative time increased from 204 to 225 min, and console time from 114 to 125 min.

CONCLUSIONS

STAR thyroid surgery is a feasible technique. Factors, such as mass size, specimen volume, and patient body mass index, had little effect on operative times. These differences should not hinder the adoption of this procedure in North America, because new retractor systems help to overcome them. Further evaluation of this procedure is reasonable and safe.

Transaxillary subpectoral augmentation mammaplasty: a single surgeon's 20-year experience

BACKGROUND

Transaxillary subpectoral augmentation mammaplasty (TASPA) is not widely accepted due to perceived limitations in pocket access, visualization, control, and subsequent risk for postoperative complications. Current published data do little to substantiate or refute those claims.

OBJECTIVE

A retrospective chart review of a single surgeon's 20-year experience with the TASPA technique was undertaken to assess the incidence of total secondary procedures, implant-related revisions, and reoperations unrelated to the implant.

METHODS

The senior author (DCM) performed 1776 primary TASPA procedures from January 1989 through December 2008. Of those, 94 patients did not meet inclusion criteria, leaving a total of 1682 records for analysis. Data reviewed included age, date of surgery, race, implant size and type, manufacturer, and reasons for reoperation.

RESULTS

Average age was 32.7 ± 8.1 years (range, 16-62). Average implant size was 438.5 ± 51.5 cc (range, 270-630). Implants from Allergan/Inamed/McGhan (Irvine, CA), Dow-Corning (Midland, MI), Mentor (Santa Barbara, CA), and Surgitek (Racine, PA) were inserted (n = 2094 saline, n = 1270 silicone). Mean follow-up time was 37.9 ± 45.4 months (range, one month to 19.8 years). Excluding staged mastopexies and treatment for breast cancer, total secondary procedures were required in 225 patients (13.4%). Implant-related revisions included malposition (2.97%), size change (2.5%), and capsular contracture (1.9%). Perioperatively, no infections occurred, and two patients (0.12%) experienced hematoma. Most reoperations (62.8%) were performed through the axilla. Comparison to published data showed an equal or lower rate of capsular contracture, hematoma, and infection with the TASPA approach.

CONCLUSIONS

Given its advantages of an inconspicuous scar, decreased infection, and decreased capsular contracture, TASPA can be safely offered to patients as an option in breast augmentation.

Sentinel lymph node biopsy in breast cancer patients with previous breast augmentation surgery

The number of breast augmentation surgeries (BAS) has increased. Therefore, the number of breast cancer patients with history of BAS has also increased. In this paper, we present two cases of sentinel lymph node biopsy (SLNB) in patients with previous BAS who were diagnosed with breast cancer. The patients were augmented using different approach; the first case was augmented through transaxillary incision, whereas the second case was augmented through periareolar incision. Lymphoscintigraphy (LPG) was performed on the patients 1 day prior to operation, enabling confirmation of lymphatic flow and SLN in both patients. SLNB was successfully performed in both cases. In one patient, SLNB was performed using indocyanine green (ICG) fluorescence and the Photodynamic Eye (PDE) system. Regardless of history of BAS, ICG and PDE system showed lymphatic flow and SLN in real time. LPG and ICG fluorescence were useful methods for SLN detection in patients with previous BAS, being able to confirm lymph flow before operation. Biopsy methods using LPG and PDE system were considered useful for difficult confirmation of lymph flow after breast augmentation. This is the first report of SLNB using ICG and PDE system for patients with previous BAS.

Evaluation of the effects of transaxillary breast augmentation on sentinel lymph node integrity

BACKGROUND

The transaxillary approach for breast augmentation has gained popularity because of the absence of scarring on the breast. However, the effects of this procedure on breast cancer detection and treatment (which rely heavily on the results of axillary status studies) remain under debate. Specifically, sentinel lymph node biopsy is not indicated for patients who have undergone axillary surgery, due to controversy about the interference of the axillary approach with evaluation of the axillary drainage.

OBJECTIVES

The authors evaluate changes in axillary lymphatic drainage in patients who underwent transaxillary breast augmentation.

METHODS

Twenty-seven patients who presented to Rio de Janeiro State University for breast augmentation were selected for this study. All patients underwent preoperative mammary lymphoscintigraphy, a subsequent transaxillary breast augmentation, and postoperative lymphoscintigraphy at 21 days and six months after the procedure. The postoperative imaging results examining the axillary lymphatic chain and the first axillary lymph node were analyzed and compared to the preoperative images.

RESULTS

One of the 27 patients (4.5%) demonstrated a lower rate of lymphatic drainage at 21 days postoperatively compared to preoperative values, but the flow rate had recovered by her six-month follow-up visit. All other patients showed no changes between the preoperative and postoperative images at either time point. The sentinel lymph node remained visible in all patients at all time points, and all breasts showed drainage primarily to the axillary lymphatic chain. Two patients experienced hematoma and one patient experienced late infection at four months postoperatively. The sentinel lymph node was still evident in both axillae.

CONCLUSIONS

The data showed preservation of lymphatic drainage and visible sentinel lymph nodes even after transaxillary breast augmentation. Therefore, the authors believe that this procedure does not alter the integrity of mammary drainage for properly selected patients. These data provide surgeons with a less invasive treatment option for patients with early breast cancer, even when they have undergone prior breast augmentation through a transaxillary approach.

Transaxillary breast augmentation: a prospective comparison of subglandular, subfascial, and submuscular implant insertion

BACKGROUND

During the last decades transaxillary breast augmentation (TBA) has gained worldwide acceptance. Breast augmentation via transaxillary access endoscopically assisted in the subglandular, subfascial, and submuscular planes has been previously described. Although TBA is a well-studied procedure, few reports exist concerning the subfascial plane of implant insertion and none exist comparing the three different planes of insertion by TBA.

METHODS

A perspective study to evaluate the outcomes, complications, and patient satisfaction of TBA using the three different planes of implant insertion was performed during 2004-2005. Fifty-three patients fulfilled the inclusion criteria. They were randomly divided into three groups corresponding to the three planes of silicone insertion. All patients had a silicone texturized implant that ranged from 190 to 300 cc. Overall satisfaction with the breast appearance after TBA was rated on a scale of 1-5, where 1 is poor, 2 is fair, 3 is good, 4 is very good, and 5 is excellent. The evaluation was made at the follow-up times of 6 months and 3 years.

RESULTS

There were 18 patients enrolled for the subcutaneous TBA (Group A), 18 for the subfascial TBA (Group B), and 17 for the submuscular TBA (Group C). Axillary incision-related complications occurred in 9% of the patients and included formation of a hypertrophic scar and small-wound dehiscence. There was no hematoma formation and no case of infection. There was one patient from Group A who developed seroma and was treated conservatively. Twenty-seven months postoperatively the same patient developed Baker III capsule contracture, which required silicone implant replacement in the subfascial plane. One case of stretch marks in a young nulliparous woman from Group B did not need treatment. One patient from Group A underwent implant exchange because of implant size dissatisfaction. Three patients in Group C had mild distortion of the implant during pectoral contracture. A meta-analysis of patient satisfaction 6 months and 3 years after TBA is presented.

CONCLUSION

Transaxillary breast augmentation provides consistent, satisfactory results with ease of dissection, when properly indicated. Although the subfascial augmentation mammaplasty has all the advantages of the subpectoral and subglandular augmentation mammaplasties and eliminates the disadvantages of increased postoperative discomfort, implant visibility, and distortion, patients of all three groups had similar rates of satisfaction. Further follow-up is needed in order to compare the long-term effects of the three different planes of insertion.
