Bilateral Autogenous Breast Reconstruction Using Perforator Free Flaps: A Single Center???s Experience

Short-term versus extended chemoprophylaxis against venous thromboembolism in DIEP flap breast reconstruction: A retrospective study of 424 patients

BACKGROUND

Autologous breast reconstruction is considered high-risk for deep vein thrombosis (DVT) and thromboembolism (PE). It is therefore recommended to treat patients undergoing these complex and lengthy procedures with DVT chemoprophylaxis. The optimal anticoagulation protocol is still not established. The objective of our study was to evaluate the need of a prolonged anticoagulation in patients undergoing microsurgical breast reconstruction.

METHODS

This retrospective cohort study compares our former anticoagulation protocol, which was given during the in-hospital stay, with our new protocol consisting of extended anticoagulation until postoperative day 25, in terms of DVT/PE risk reduction. A logistic regression was used to evaluate the risk of DVT/PE between the two groups, while adjusting for several covariates.

RESULTS

Our cohort consisted of 205 patients in the short-term anticoagulation group and 219 in the extended protocol group. Five patients (2.4%) in the short-term anticoagulation group had a DVT/PE event versus 4 patients (1.8%) in the extended protocol group. Logistic regression revealed no difference in the incidence of DVT/PE between the two groups. Similarly, there was no differences in terms of hematoma and infection rate between the two groups. Finally, we found an increased risk of DVT/PE in patients with a Caprini score equal or greater than 8.

CONCLUSION

In our experience, short-term anticoagulation during the hospital stay is equivalent to extended thromboprophylaxis in terms of DVT/PE prevention.

Contributors to post-operative venous thromboembolism risk after breast cancer surgery: A systematic review and meta-analysis

INTRODUCTION

Venous thromboembolism (VTE) events are a preventable complication for patients undergoing surgery for breast cancer. However, there is a lack of consistency in the existing literature regarding the potential risk factors affecting these individuals.

METHODS

This study aimed to investigate the potential risk factors associated with an increased risk of VTE following surgery for breast cancer. Data on patient characteristics such as age, body mass index (BMI), existing comorbidities, smoking history, surgical interventions, duration of hospitalization, and post-operative complications were recorded and analyzed.

RESULTS

Thirty-one studies investigating the incidence of VTE following surgical interventions for breast cancer were included. This study included 22,155 female patients with a mean age of 50.8 ± 2.9 years. The weighted mean length of surgery and hospital stay were 382.1 ± 170.0 min and 4.5 ± 2.7 days, respectively. The patients were followed-up for a weighted mean duration of 13.8 ± 21.2 months. The total incidence of VTE events was 2.2% (n = 489). Meta-analysis showed that patients with post-operative VTE had a significantly higher mean age and BMI, as well as longer mean length of surgery (P < 0.05). Comparing the techniques of autologous breast reconstruction showed that the risk of post-operative VTE is significantly higher with deep inferior epigastric perforator (DIEP) flaps, compared with the transverse rectus abdominus myocutaneous and latissimus dorsi myocutaneous flaps (P < 0.05). Compared with delayed reconstruction, immediate reconstruction was associated with a significantly higher incidence of VTE (P < 0.05). Smoking history, length of hospital stay, and Caprini score did not correlate with increased incidence of post-operative VTE.

CONCLUSION

The incidence rate of VTE events in patients receiving surgical treatment for breast cancer is 2.2%. Risk factors for developing post-operative VTE in this patient population were found to be older age, increased BMI, extended length of surgical procedures, and DIEP flap reconstruction.

An Effective Protocol for Perioperative Venous Thromboembolism Prophylaxis in DIEP Flap Breast Reconstruction: A Single Institution Retrospective Review

Background

Deep inferior epigastric artery perforator (DIEP) free flap breast reconstruction is one of the most highly used procedures for autologous breast reconstruction. Many venous thromboembolism (VTE) risk assessment models have been proposed in breast reconstructive surgery, including the widely used Caprini score. However, a paucity of data suggests an effective standardized VTE protocol. The purpose of this study was to determine the rate of VTE in our DIEP flap patients who were treated with this protocol.

Methods

A retrospective single-center review of DIEP flap breast reconstruction from 2016 to 2021 was performed. Data were collected on 554 patients and 893 flaps including demographics, intraoperative and perioperative details, and postoperative course. Patients who were not treated with our standard protocol were excluded. Data were analyzed with alpha = 0.05.

Results

The average age was 50.4 ± 9.9 years, and the total follow-up time was 16.9 ± 12.6 months. The average body mass index for the cohort was 30.1 ± 5.2. During the 90 postoperative days, the mean length of hospital stay was 4.3 days. There were six cases of postoperative VTE: five patients presented with pulmonary embolism (0.9%) and one patient (0.2%) had deep venous thrombosis with an overall VTE prevalence of 1.1%. No specific single factor could be attributed to VTE occurrence.

Conclusions

Using our standardized VTE prophylaxis protocol, our institution was effective at keeping VTE rates low. Additional studies would be beneficial to determine optimal VTE prophylaxis protocols in higher-risk patients, such as those with known clotting disorders.

Incidence of Venous Thromboembolism Based on Caprini Score in Deep Inferior Epigastric Perforator Flap Breast Reconstruction

BACKGROUND

 Deep inferior epigastric perforator (DIEP) flaps are commonly used for autologous breast reconstruction, but reported rates of venous thromboembolism (VTE) are up to 6.8%. This study aimed to determine the incidence of VTE based on preoperative Caprini score following DIEP breast reconstruction.

METHODS

 This retrospective study included patients who underwent DIEP flaps for breast reconstruction between January 1, 2016 and December 31, 2020 at a tertiary-level, academic institution. Demographics, operative characteristics, and VTE events were recorded. Receiver operating characteristic analysis was performed to determine the area under the curve (AUC) of the Caprini score for VTE. Univariate and multivariate analyses assessed risk factors associated with VTE.

RESULTS

 This study included 524 patients (mean age 51.2 ± 9.6 years). There were 123 (23.5%) patients with the Caprini score of 0 to 4, 366 (69.8%) with scores 5 to 6, 27 (5.2%) with scores 7 to 8, and 8 (1.5%) patients with scores >8. Postoperative VTE occurred in 11 (2.1%) patients, at a median time of 9 days (range 1-30) after surgery. VTE incidence by the Caprini score was 1.9% for scores 3 to 4, 0.8% for scores 5 to 6, 3.3% for scores 7 to 8, and 13% for scores >8. The Caprini score achieved an AUC of 0.70. A Caprini score >8 was significantly predictive of VTE on multivariable analysis relative to scores 5 to 6 (odds ratio = 43.41, 95% confidence interval = 7.46-252.76, p < 0.001).

CONCLUSION

 In patients undergoing DIEP breast reconstruction, VTE incidence was highest (13%) in Caprini scores greater than eight despite chemoprophylaxis. Future studies are needed to assess the role of extended chemoprophylaxis in patients with high Caprini scores.

Natural course of fat necrosis after deep inferior epigastric perforator flap-based breast reconstruction: Evaluation based on ultrasound examination

BACKGROUND

Fat necrosis, often developing following deep inferior epigastric perforator (DIEP) flap-based breast reconstruction, is not a negligible complication. This study aimed to conduct a longitudinal assessment of the clinical course of fat necrosis in breast reconstruction with DIEP flap.

METHODS

Among patients undergoing immediate DIEP flap-based breast reconstruction between 2009 and 2017, those who developed fat necrosis on ultrasonographic examination and did not undergo surgical intervention for the lesion were reviewed. Changes in lesion size over time were assessed based on regular ultrasound examinations.

RESULTS

A total of 37 cases were analyzed, with a mean follow-up of 52.6 months (range, 19-114). Their mean age was 45.8 years, and the mean body mass index was 23.4 kg/m2 . Of these, 21 lesions had disappeared over time. The mean time from detection to the disappearance was 30.4 months. The remaining 16 lesions did not disappear and persisted for a median follow-up of 43.5 months. Compared with the lesions that persisted, those that disappeared were significantly smaller in initial size (p = 0.040) and had a lower inset ratio of the harvested flap (p = 0.006). The optimal cutoff value for the initial size for disappearance was ≤1.97 cm. Among the lesions >1.97 cm in size, 6 (35.3%) of 17 lesions disappeared, whereas in those ≤1.97 cm, 15 (75.0%) of 20 disappeared over time, with a significant difference (p = 0.041).

CONCLUSION

The natural course of fat necrosis that develops following the DIEP flap may differ according to its initial size.

Intercostal Artery Perforator Flap for Salvage Breast Reconstruction with Exposed Breast Implants

Multiple techniques have been described for breast reconstruction surgery after breast implant exposure; breast implant removal and delayed breast reconstruction is the procedure of choice. However, in some mild exposures and infections, we propose an alternative treatment.

Methods

This is a case series of a 14-year study in 16 female patients with mild exposure of a breast implant after breast reconstruction surgery. Salvage surgery was performed on these cases. The defects were between 1 and 6 cm, with a median size of 3.9 × 2.9 cm. Eighteen intercostal artery perforator flaps were used with an island of skin from the inframammary fold; 83.3% were anterior intercostal artery perforator flaps' and 16.7% were lateral intercostal artery perforator flaps.

Results

Thirteen of the 16 patients presented infection (81.25%). There was no necrosis of any flap, and the success rate of salvage surgery was 62.5% of all patients. The success of surgery was 53.8% in patients with breast infection and 100% in patients without infection. Seven patients received chemotherapy and radiotherapy, six received only chemotherapy, and nine patients received only radiotherapy. Five of the six patients whose salvage surgery failed were treated with radiotherapy.

Conclusion

This technique can be used as an alternative when there is exposure of the implant' even in cases with a mild breast infection and in patients undergoing radiotherapy and chemotherapy.

Safety and Efficacy of the Superior Gluteal Artery Perforator (SGAP) Flap in Autologous Breast Reconstruction: Systematic Review and Meta-Analysis

Simple Summary

Breast reconstruction following mastectomy is associated with higher patient satisfaction and quality of life. Autologous breast reconstruction has become increasingly popular in recent decades and offers good long-term results. While the abdomen is typically chosen as the donor site for autologous breast reconstruction, it can be unsuitable for some patients. In this setting, different donor sites, such as the buttocks, can be used to reconstruct the breast. The superior gluteal artery perforator (SGAP) flap is a safe alternative to the deep inferior epigastric artery perforator (DIEP) flap and provides good esthetic results, making it a valuable option for breast cancer patients desiring a postmastectomy autologous breast reconstruction.

Abstract

(1) Background: The superior gluteal artery perforator (SGAP) flap is a prominent technique for autologous breast reconstruction. Unlike other commonly used techniques, current literature on the safety and efficacy of the SGAP flap is heterogenous and limited. The aim of this article was to perform a systematic literature review and meta-analysis of postoperative outcomes and complications associated with SGAP flap autologous breast reconstructions. (2) Methods: A systematic literature search of multiple databases was performed using the PRISMA guidelines. We included articles evaluating SGAP flaps in autologous breast reconstruction. Outcomes and complications were recorded and analyzed. Proportions and their 95% confidence intervals (CIs) were calculated in a random-effects meta-analysis. (3) Results: Fourteen studies meeting inclusion criteria, representing a total of 667 SGAP flaps, were included. The total flap loss rate was 1% (95% CI 0–3%), partial flap loss rate was 1% (95% CI 0–3%), hematoma rate was 3% (95% CI 1–6%), emergent surgical re-exploration rate was 5% (95% CI 2–9%), and overall donor-site complications were 12% (95% CI 4–23%). (4) Conclusions: This systematic review and meta-analysis provide comprehensive knowledge on the efficacy and safety of the SGAP flap in autologous breast reconstruction. It demonstrates its overall safety and low complication rate, validating its important role as an effective option in breast reconstruction.

Deep inferior epigastric perforator (DIEP) flap safety profile in slim versus non-slim BMI patients: A systematic review and meta-analysis

BACKGROUND/PURPOSE

The complications of breast reconstruction using deep inferior epigastric perforator (DIEP) flaps in non-slim patients are well recognized. However, the effects of this surgery performed on slim patients are yet to be consolidated. This study aims to compare the outcomes of performing DIEP flap breast reconstruction in slim and non-slim body mass index (BMI) patients.

METHODS

Meta-analysis was performed with a multi-database search (Cochrane, EMBASE, OVID Medline, PubMed, and Web of Sciences) according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines on 1 February 2021. Data from articles meeting inclusion criteria were extracted and analyzed with an inverse variance statistical model.

RESULTS

Seven studies were included, comprising 574 slim patients and 901 non-slim BMI patients who underwent autologous DIEP flap breast reconstruction. When comparing between the slim and non-slim groups, no statistically significant difference was found in terms of complete flap loss (OR=0.53, 95% CI: 0.11-2.68, p=0.44), partial flap loss (OR=0.92, 95% CI: 0.3-2.82, p=0.88), and fat necrosis (OR=0.91, 95% CI: 0.61-1.37, p=0.66). Similarly, in terms of general surgical complications, there was no statistically significant difference between groups in terms of all complications (OR=0.83, 95% CI: 0.45-1.51, p=0.54), abdominal wound healing complications (OR=1.01, 95% CI: 0.59-1.73, p=0.97), infections (OR=0.74, 95% CI: 0.41-1.37, p=0.34), and seroma (OR=0.89, 95% CI: 0.35-227, p=0.81).

CONCLUSION

There is no increased risk of postoperative complications in either group. DIEP flaps can be safely performed in slim patients, though higher quality research may be required to further confirm this.

Prolonged Venous Thromboembolism Prophylaxis May Not Be Necessary for DIEP Flap Breast Reconstruction: A Tertiary Center's 10-Year Experience

BACKGROUND

 Based on the 2005 Caprini Risk Assessment Model for venous thromboembolism, the American Society of Plastic Surgeons prevention guidelines would result in prolonged chemoprophylaxis (1 week or more) for the majority of patients undergoing deep inferior epigastric perforator flap breast reconstruction. We aim to assess the necessity of prolonged prophylaxis by describing our institutional experience in thromboembolism prevention and evaluating the incidence of symptomatic VTE in our patient cohort.

METHODS

 Women who underwent DIEP flap reconstruction from August 2011 to March 2020 at a tertiary care center were included. Charts were retrospectively reviewed for patient characteristics, VTE prophylaxis regimens, and development of deep vein thrombosis and pulmonary embolism within 60 days of surgery. Caprini scores were calculated for all patients.

RESULTS

 Out of the 249 patients included in the study, 245 patients received chemoprophylaxis only during hospitalization, while four patients additionally received anticoagulant for at least 2 weeks after discharge for prophylactic or therapeutic indications. The cohort's average Caprini score was 6.0, with 72.7% of scores between 3 and 6 and 26.5% at 7 or higher. One patient (0.4%), who scored a 7 and received prophylaxis only while hospitalized, developed deep vein thrombosis. There were no cases of pulmonary embolism. There was no significant difference in VTE rate between patients who received chemoprophylaxis consistent with ASPS guidelines and those who did not (p = 1.000).

CONCLUSION

 Despite our limited chemoprophylaxis use in DIEP flap patients, our VTE incidence is low. This current work suggests that the blanket application of prolonged prophylaxis is not warranted, and it further serves as impetus to re-evaluate the 2005 Caprini RAM in this patient population.

[Secondary surgery of breast reconstructions by breast implant. Assessment of patient satisfaction based on surgical technique implant conservation vs. autologous conversion]

INTRODUCTION

Breast reconstruction with implants has long-term disadvantages and is leading an increasing number of patients to request secondary corrective surgery. Two surgical strategies are possible: implant replacement (associated with capsulectomy/capsulotomy and/or lipofilling procedures) and implant removal associated with the provision of autologous tissue (flap and/or lipofilling).

METHOD

Between 2010 and 2018, 54 patients underwent secondary surgery for correction of a first implant breast reconstruction. The reasons for dissatisfaction with the initial reconstruction, the procedures performed, and postoperative complications were analysed. Patient well-being and satisfaction were evaluated using the BREAST-Q questionnaire.

RESULTS

Thirty-four patients benefited from a prosthesis change and 20 patients benefited from a permanent removal of their prosthesis combined with the addition of autologous tissue. The presence of a periprosthetic shell, pain, fixed appearance of the breast and breast asymmetry were the most frequent reasons for dissatisfaction. With a mean follow-up of 2.6 years, autologous conversion patients were generally more satisfied with the appearance of their breasts than patients who retained a breast implant (P<0.0001).

CONCLUSION

In cases of poor esthetic or functional outcomes of implant-based breast reconstruction, removal of the prosthesis in combination with autologous reconstruction provides better results in terms of well-being and satisfaction than implant replacement.

Bilateral Simultaneous Breast Reconstruction with DIEP- and TMG Flaps: Head to Head Comparison, Risk and Complication Analysis

Background: A two center retrospective cohort study of simultaneous bilateral breast reconstructions using double deep inferior epigastric perforator (DIEP) flaps and double transverse myocutaneous/upper gracilis (TMG) flaps was conducted. The aim of this study was to compare surgical procedures, complications, and overall outcome. Patients and Methods: Two study groups, either receiving a simultaneous bilateral breast reconstruction, with double DIEP flaps (n = 152) in group 1, or double TMG flaps (n = 86) in group 2, were compared. A detailed risk and complication analysis was performed. Patient characteristics, operative time and the need for further operations were evaluated. Results: Double DIEP patients had donor site complications in 23.7% and double TMG patients in 16.3% (p = 0.9075, RR 1.45). Flap loss rates of 3.5% (double TMG) and 2.6% (double DIEP) were recorded (p = 0.7071, RR 1.33). The need for postoperative lipofilling was significantly higher in double TMG patients (65.1% vs. 38.2 %, p = 0.0047, RR 1.71). Conclusion: Complication analysis favors the double DIEP procedure. Donor site morbidity was lower and less severe in the double TMG group. Later fat grafting was more frequently needed after double TMG reconstructions. Further studies, preferably of prospective nature, are needed to evaluate the benefit of bilateral simultaneous breast reconstructions.

Autologous Breast Reconstruction with SIEA Flaps: An Alternative in Selected Cases

BACKGROUND

The deep inferior epigastric perforator flap has been shown to be a reliable option for autologous breast reconstruction. A further refinement in the transfer of lower abdominal tissue is the superficial inferior epigastric artery (SIEA) flap that does not require any incision of the rectus abdominis fascia or muscle and is superior regarding donor-site morbidity.

OBJECTIVES

We conducted a retrospective study to assess reliability and outcomes of autologous breast reconstruction using SIEA flaps.

METHODS

We performed autologous breast reconstruction in 1708 patients at our department between 2009 and 2018. Of those, 28 patients that underwent breast reconstruction using a SIEA flap were included for a retrospective chart review.

RESULTS

Given an overall flap loss rate of 1.8%, we observed total flap necrosis following a SIEA flap in four patients (13%). All cases were secondary to arterial thrombosis. We further recognized a significant correlation between flap failure and a history of spontaneous deep vein thrombosis (p < 0.0001). There was no statistically significant relationship between flap failure and obesity (BMI > 30 kg/m^2;p = 0.9) or flap failure and a history of abdominal operations (p = 0.6).

CONCLUSIONS

The SIEA flap provides a reasonable option for autologous breast reconstruction with the great advantage of minimal donor-site morbidity. Nevertheless, its use should be preserved to selected cases with favorable anatomy. We therefore recommend proper patient selection based on preoperative computed tomography angiography, intraoperative clinical evaluation and history of hypercoagulable state.

The Timing of Chemoprophylaxis in Autologous Microsurgical Breast Reconstruction

BACKGROUND

Patients undergoing autologous breast reconstruction are at high risk of perioperative venous thromboembolic events. The efficacy of chemoprophylaxis in decreasing venous thromboembolic events is well established, but the timing of chemoprophylaxis remains controversial. The authors compare the incidence of bleeding following preoperative versus postoperative initiation of chemoprophylaxis in microvascular breast reconstruction.

METHODS

A retrospective chart review was performed from August of 2010 to July of 2016. Initiation of chemoprophylaxis changed from postoperative to preoperative in 2013, dividing subjects into two groups. Patient demographics, comorbidities, and complications were reviewed.

RESULTS

A total of 196 patients (311 flaps) were included in the study. A total of 105 patients (166 flaps) received preoperative enoxaparin (40 mg) and 91 patients (145 flaps) received postoperative chemoprophylaxis. A total of five patients required hematoma evacuation (2.6 percent). Of these, one hematoma (1 percent) occurred in the preoperative chemoprophylaxis group. Seven patients received blood transfusions: three in the preoperative group and four in the postoperative group (2.9 percent versus 4.4 percent; p = 0.419). There was a total of one flap failure, and there were no documented venous thromboembolic events in any of the groups.

CONCLUSIONS

This study demonstrates that preoperative chemoprophylaxis can be used safely in patients undergoing microvascular breast reconstruction. The higher rate of bleeding in the postoperative group may be related to the onset of action of enoxaparin of 4 to 6 hours, which allows for intraoperative hemostasis in the preoperative group and possibly potentiating postoperative oozing when administered postoperatively.

Impact of Prior Tissue Expander/Implant on Postmastectomy Free Flap Breast Reconstruction

BACKGROUND

Implant-based breast reconstructions can result in unsatisfactory results requiring surgical revision or salvage reconstructive surgery with autologous tissue. This study compares the outcomes and complications of salvage (tertiary) flap reconstruction after failed prosthesis placement to those of primary/secondary flap reconstruction.

METHODS

All patients undergoing free flap breast reconstruction after failed prosthesis between July 1, 2005, and June 30, 2014, were identified. A matched number of patients who underwent a de novo free flap breast reconstruction were selected randomly for review. The indication for prosthesis removal, demographic and operative data, flap type and inset, and complication rates were evaluated.

RESULTS

Eighty-nine women with a history of failed implant-based reconstruction required free flap reconstruction for salvage in 121 breasts. Capsular contracture was the most common indication for prosthesis removal (62.0 percent). Recipient vessel scarring was 5.23 times more likely to occur in the prior prosthesis group (p < 0.001). Alternate flap types other than deep inferior epigastric perforator and transverse rectus abdominis myocutaneous flaps were more frequently used in this cohort. Major complications requiring operative management were more common in the experimental group (17.4 percent versus 8.1 percent; p = 0.035). No difference was noted in flap loss rates, operative take back, or operative time.

CONCLUSIONS

Salvage breast reconstruction with autologous tissue after failed prosthesis can be safely performed, with success rates similar to those of primary free flap breast reconstruction. However, these procedures may have increased complexity because of recipient vessel scarring, higher rates of prior radiation therapy, and major complications, which may warrant appropriate preoperative planning and patient counseling.

Bilateral Breast Reconstruction with Extended Thoracodorsal Artery Perforator Propeller Flaps and Implants

We present our experience of bilateral total breast reconstruction using a double-sided extended thoracodorsal artery perforator propeller flap in a case series of 10 patients. Reconstruction was successfully achieved in all cases with few complications. The median time for surgery was 275 minutes (200–330), and the average implant size used was 350 cm³ (195–650). We demonstrate how the extended thoracodorsal artery perforator propeller flap allows for a swift and reliable direct to implant bilateral total breast reconstruction in a simple setting and is a valuable adjunct to our armamentarium of techniques for single-stage bilateral breast reconstruction.

Double transverse myocutaneous gracilis free flaps for unilateral breast reconstruction

BACKGROUND

In cases were the deep inferior epigastric perforator flap (DIEP flap) is not available and unilateral transverse myocutaneous gracilis flap (TMG flap) is not sufficient for breast reconstruction, we perform double TMG flaps as a reconstructive method. In this report, we present our results of the use of double TMG free-flap-transfer for unilateral breast reconstruction.

PATIENTS AND METHODS

Between August 2004 and June 2012 we performed 58 TMG flaps in 29 patients for unilateral breast reconstruction. Patient data were analyzed and operative outcome (operation time, complication rate and aesthetic results) were investigated. Aesthetic outcome was evaluated retrospectively via photo documentation by an independent plastic surgeon. The results were classified in;unsatisfactory, satisfactory, good and very good.

RESULTS

The average operating time was 6 hours 55 minutes (295 - 650 minutes). Of 58 TMG flaps, 57 (98.3%) were successful. Thrombosis occurred in seven (12%) cases (1 arterial, 6 venous). Flap salvage was successful in six cases and flap failure occurred in one (1.7%) case. The results of 25 patients were graded as good and very good. Three patients showed satisfying and one patient unsatisfying results.

CONCLUSION

Double TMG flaps in unilateral breast reconstruction could lead to good operative results. This method further expands the range of options with autologous tissue in reconstructive breast surgery. © 2015 Wiley Periodicals, Inc. Microsurgery 36:539-545, 2016.

One-staged silicone implant breast reconstruction following bilateral nipple-sparing prophylactic mastectomy in patients at high-risk for breast cancer

BACKGROUND

There is little consensus regarding the indications, ideal incision, or reconstruction method for prophylactic mastectomy. In addition, the biggest limitation in studies that assess either patient satisfaction or operation results is the lack of group homogeneity.

METHODS

In our center, 21 bilateral prophylactic mastectomies, due to breasts at high risk for cancer, and simultaneous breast reconstruction using submuscular medium-height high-profile silicone implants were performed between 2008 and 2012. The patients were divided into two groups: small-breasted (9 patients) and large/ptotic-breasted (12 patients). A periareolar incision was used in the 9 patients and a vertical mastopexy incision was used in the 12 patients who needed nipple-areola complex repositioning.

RESULTS

The rates of general satisfaction and aesthetic outcomes, assessed using the Michigan Breast Satisfaction Questionnaire, were 100 and 90.4%, respectively. Seroma occurred in three patients and venous congestion of the nipple-areola complex developed in four patients, which resolved spontaneously. No nipple-areola necrosis, implant exposition, or capsule contractures were encountered. Only three patients underwent fat injection for contour restoration.

CONCLUSION

We obtained very good aesthetic results with low complication rates using this technique in a homogeneous group of patients.

A comparison of the superficial inferior epigastric artery flap and deep inferior epigastric perforator flap in postmastectomy reconstruction: A cost-effectiveness analysis

PURPOSE

To perform a cost-effectiveness analysis comparing the superficial inferior epigastric artery (SIEA) and deep inferior epigastric perforator (DIEP) flaps in postmastectomy reconstruction.

METHODS

A decision analytic model with seven clinically important health outcomes (health states) was used, incorporating the Ontario Ministry of Health's perspective. Direct medical costs were estimated from a university-based hospital. The utilities of each health state converted into quality-adjusted life years (QALYs) were obtained from previously published data. Health state probabilities were computed from a systematic literature review. Analyses yielded SIEA and DIEP expected costs and QALYs allowing calculation of the incremental cost-utility ratio (ICUR). One-way sensitivity analyses were conducted under five plausible scenarios, assessing result robustness.

RESULTS

Five SIEA and 27 DIEP studies were identified. The baseline SIEA expected cost was slightly higher than that for the DIEP ($16,107 versus $16,095), with slightly higher QALYs (33.14 years versus 32.98 years), giving an ICUR of $77/QALY. Taking into account conversions from SIEA to DIEP, the ICUR increased to $4,480/QALY. Sensitivity analysis gave ICURs ranging from $2,614/QALY to 'dominant', all consistent with the adoption of the SIEA over the DIEP.

CONCLUSION

The best available evidence suggests the SIEA is a cost-effective procedure. However, given the high SIEA to DIEP conversion rates and small marginal differences in cost and effectiveness, the ICUR may be sensitive to minor changes in costs or QALYs. The 'truth' can only be obtained from a randomized, controlled trial comparing both techniques side by side, simultaneously capturing the costs of the competing interventions.

Advances in local-regional treatment for patients with early-stage breast cancer: a review of the field

This review highlights advances in the field of the local-regional treatment for patients with early-stage breast cancer. Through the years, the surgical treatment for early-stage breast cancer has evolved into more conservative treatment, with breast-conserving measures replacing the mastectomy as the most common procedure performed to treat the primary tumor. Likewise, nodal staging has evolved so that the lymphatic mapping procedures have replaced axillary dissection, resulting in a less morbid procedure and better staging information. Advances in radiation treatment have resulted in increasingly tailored approaches to adding radiation treatment after breast-conserving surgery or mastectomy. These improvements in local-regional treatment have benefitted patients through increased breast conservation treatment, improved local control, increased survival, and improved quality of life.

Salvage (tertiary) breast reconstruction after implant failure

BACKGROUND

Salvage breast reconstruction is defined as a complete revision of a previous reconstruction in case of unsatisfactory results or failure of primary or secondary breast reconstruction. We have termed this 'tertiary breast reconstruction'. This article presents our experience with tertiary reconstructions, including the indications, method of reconstruction and outcomes.

METHODS

A retrospective note review was performed for all patients who underwent breast reconstruction with autologous tissue under one surgeon between 2002 and 2009 at the University Hospital, Ghent. Out of these 688 patients, 54 patients (7.8%) required tertiary surgery with autologous tissue after failure of implant breast reconstruction.

RESULTS

The first reconstructive surgery involved 38 unilateral and 16 bilateral cases with a total of 70 operated breasts. A further 11 breasts were reconstructed following risk-reducing mastectomy or at the patient's request for aesthetic reasons. Out of 81 free-flap reconstructions, the deep inferior epigastric artery perforator (DIEAP) flap was the most harvested at 66 (81%). The mean±SD operating time was 7.2±1.8 h and the mean hospital stay was 7.2±1.9 days. One total flap loss (1.2%) occurred. The mean follow-up was 31 months with a range between 3 months and 6 years. During follow-up, 30 patients (55.5%) needed secondary procedures to improve the aesthetic outcome. Donor-site corrections were performed in 18 patients (33%). Revisions of the breast flap were performed in 29 patients (53%).

CONCLUSIONS

Restoring the breast envelope and footprint, in addition to excision of scar tissue, is the key step in breast reconstruction. Further corrections are required depending on the amount of the initial damage to the breast or subsequent postoperative complications.

Bilateral breast reconstruction with DIEP flaps: 4 years’ experience

Bilateral prophylactic mastectomy without reconstruction is not accepted by the majority of patients. Successful reconstruction is therefore a mandatory condition for prophylactic mastectomy. Of the many options for autologous breast reconstruction, the deep inferior epigastric perforator (DIEP) flap best meets requirements for bilateral reconstruction in selected patients. The goal of this study is to verify the feasibility of the procedure in our conditions and to find out how it is accepted by patients. We present 55 consecutive patients who were scheduled for bilateral DIEP flap reconstruction during a 4-year period. We reviewed medical charts, performed clinical assessments and processed anonymous questionnaires. There were 77 immediate and 33 delayed breast reconstructions. There was 100% flap survival and no microanastomoses revisions. In 11 patients (10%) the surgeon preferred to convert the DIEP into a mini transverse rectus abdominis muscle (miniTRAM) flap in order to provide adequate blood supply.

COMPLICATIONS

revision for haematoma under the flap in four patients (7.2%), excessive blood loss in four patients (7.2%) and partial mastectomy skin flap necrosis in 10 immediate breast reconstructions (12.9%). Patients' evaluation of the aesthetic result was good or excellent in 96.2% of cases. In 33.9% of patients the postoperative quality of life was considered unchanged and 50.9% of them it even improved. The DIEP flap is recommended for bilateral breast reconstruction. Occasional conversion into a miniTRAM flap can increase the total flap survival rate. Bilateral prophylactic mastectomy and DIEP flap reconstruction are very well accepted by patients.

Refinements of the LeJour vertical mammaplasty skin pattern for skin-sparing mastectomy and immediate breast reconstruction

BACKGROUND

Skin-sparing mastectomy (SSM) is a well-established technique for immediate breast reconstruction (IBR). When used for large and/or ptotic breasts, traditional SSM patterns produce long skin flaps prone to necrosis or 'T' junction breakdown. The authors have previously demonstrated the applicability of the LeJour-type vertical mammaplasty skin pattern to this group of patients. With further experience, indications for this procedure have been widened and the technique refined.

RESULTS

Over five years, 26 immediate breast reconstructions were carried out in 19 patients using this technique: three expandable implants, seven LDs, three pedicled TRAMs, five free TRAMs, seven DIEPs and one SIEA flap. Fourteen patients (74%) had simultaneous contralateral balancing LeJour breast reductions or mastopexies. The remaining five patients had bilateral mastectomies and reconstructions using the vertical mammaplasty skin pattern for both breasts. All flaps were successful, but there were three cases of minor skin flap necrosis, three of delayed wound healing and two instances of significant post-operative bleeding. Cosmesis was suboptimal in the prosthetic reconstruction group, necessitating revisional surgery.

DISCUSSION AND CONCLUSIONS

The vertical mammaplasty skin pattern was successfully used with a wide range of reconstructions. However, to avoid suboptimal cosmetic results and minimise wound healing problems this technique is not recommended in heavy smokers, very obese patients, those undergoing prosthetic reconstructions or neoadjuvant chemotherapy. The skin resection pattern should also be conservative. The LeJour-type vertical mammaplasty pattern is a viable alternative technique for SSM in selected patients, especially those requiring contralateral balancing surgery and undergoing autologous tissue reconstruction.

Breast reconstruction using deep inferior epigastric perforator flaps in EEC syndrome

Ectrodactyly, ectodermal dysplasia, cleft lip/palate (EEC) syndrome is a rare condition that may result in failure of breast development. Breast reconstruction in these patients may pose a challenging problem, as they are young and reconstructive options should have minimal long-term complications. The use of deep inferior epigastric perforator (DIEP) flaps in breast reconstruction following breast cancer has been well described with good results. The use of DIEP flaps in breast augmentation, however, is far less common. We present the case of a young patient with EEC syndrome and mammary hypoplasia who underwent DIEP flap reconstruction for breast augmentation. The outcome was satisfactory to both patient and surgeon.

Deep Inferior Epigastric Perforator Flap for Successful Simultaneous Breast and Chest Wall Reconstruction in a Poland Anomaly Patient

Breast reconstruction in female Poland anomaly remains a surgical challenge with variable chest wall deformity and nipple position. Pedicled latissimus dorsi myocutaneous flap with implant reconstruction may have several drawbacks and complications. Free deep inferior epigastric flap (DIEP) flap is a reliable option for postmastectomy breast reconstruction, but rarely reported in Poland anomaly. We presented a 52-year-old Poland anomaly patient who underwent successful reconstruction for breast and chest wall deformity using DIEP flap. Preoperative ultrasound Doppler study for internal mammary vessels is recommended for microsurgical anastomosis. Care should be taken with regard to the flap inset and the location of the nipple areolar complex.
