Plastic and Reconstructive Surgery: February 2021 - Volume 147 - Issue 2 - p 294-303

 

Background:

Multiple perforator flap breast reconstruction is an option that avoids implants in selected patients with minimal donor tissue. The technique addresses the need for additional skin to help create a breast envelope with more natural ptosis and additional volume to help create a body-appropriate breast mound while avoiding serial fat grafting. Using four flaps for the reconstruction of two breasts (bilateral stacked flap reconstruction) has recently become feasible with the advancement of microsurgical techniques, increased experience with alternative perforator flaps, and use of co-surgery. In this article, we describe our early experience with bilateral stacked flap breast reconstruction.

Methods:

From January of 2014 to October of 2018, the senior co-surgeons performed 50 consecutive bilateral stacked flap operations at a single institution. All reconstructions were performed in delayed fashion with a mean operative time of 10 hours. Most breasts (94 percent) were reconstructed with a deep inferior epigastric perforator flap combined with a profunda artery perforator flap. Most flap microanastomoses (91.5 percent) were performed directly with internal mammary vessels. The larger of the two flaps was typically placed inferiorly (66 percent), but there was significant inset variability.

Results:

Of 200 flaps, five were lost (2.5 percent). Seven take-backs were needed for a flap-related concern, which included two negative explorations and a flap salvage. The most common non–flap-related complication was a thigh wound (17 total, eight requiring a procedure).

Conclusion:

The authors’ early experience suggests that bilateral stacked flap breast reconstruction is a powerful tool that can be performed with an acceptable microsurgical risk and an acceptable complication profile in highly selected patients.

Kim, Jae Bong; Eom, Jeung Ryeol; Lee, Jeong Woo; Lee, Jeeyeon; Park, Ho Yong; Yang, Jung Dug  

Plastic and Reconstructive Surgery: March 2019 - Volume 143 - Issue 3 - p 477e–487e

Background: Immediate partial breast reconstruction after breast-conserving surgery has become a new paradigm in treating breast cancer. Among the volume replacement techniques used for small to moderate-sized breasts, the perforator flap method has many advantages. The authors present anatomical studies and two surgical techniques using lateral intercostal artery perforator flaps. Methods: Data from 40 patients who underwent breast reconstruction using the lateral intercostal artery perforator flap between January of 2011 and June of 2016 were included. The authors conducted comparative analyses of the propeller flap and the turnover flap. They used three-dimensional computed tomography in lateral intercostal artery perforator flap anatomical studies, analyzing the distribution probability of the dominant perforator, the vertical distance from the axillary fold, and the horizontal distance from the anterior border of the latissimus dorsi.
Results: The most dominant perforator used for lateral intercostal artery perforator flaps was the sixth lateral intercostal artery perforator (43.6 percent of cases), followed by the seventh lateral intercostal artery perforator (39.1 percent of cases); their mean distances from the latissimus dorsi and the axillary folds were determined and reported. Complications included three cases requiring additional treatment for fat necrosis (propeller method, two cases; turnover method, one case) and venous congestion in only two cases that used the propeller method. Cosmetic satisfaction was 90 percent or greater for both techniques, indicating that results were rated as either excellent or good. Conclusion: The authors believe that their study results can broaden the application of partial breast reconstruction by using the lateral intercostal artery perforator flap after breast-conserving surgery, with three-dimensional computed tomography for anatomical studies, and using one of the authors’ two described surgical techniques. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

The Stacked Hemiabdominal Extended Perforator Flap for Autologous Breast Reconstruction



 by Beugels, Jop; Vasile, Julie V.; Tuinder, Stefania M. H.; Delatte, Stephen J.; St-Hilaire, Hugo; Allen, Robert J.; Levine, Joshua L.  

Plastic and Reconstructive Surgery: December 2018 - Volume 142 - Issue 6 - p 1424–1434

Background: Options for bilateral autologous breast reconstruction in thin women are limited. The aim of this study was to introduce a novel approach to increase abdominal flap volume with the stacked hemiabdominal extended perforator (SHAEP) flap. The authors describe the surgical technique and analyze their results.
Methods: A retrospective study was conducted of all SHAEP flap breast reconstructions performed since February of 2014. Patient demographics, operative details, complications, and flap reexplorations were recorded. The bipedicled hemiabdominal flap was designed as a combination of the deep inferior epigastric artery perforator (DIEP) and a second, more lateral pedicle: the deep or superficial circumflex iliac perforator vessels, the superficial inferior epigastric artery, or a lumbar artery or intercostal perforator.
Results: A total of 90 SHAEP flap breast reconstructions were performed in 49 consecutive patients. Median operative time was 500 minutes (range, 405 to 797 minutes). Median hemiabdominal flap weight that was used for reconstruction was 598 g (range, 160 to 1389 g). No total flap losses were recorded. Recipient-site complications included partial flap loss (2.2 percent), hematoma (3.3 percent), fat necrosis (2.2 percent), and wound problems (4.4 percent). Minor donor-site complications occurred in five patients (10.2 percent). Most flaps were harvested on a combination of the DIEP and deep circumflex iliac artery vessels.
Conclusions: This study demonstrated that the SHAEP flap is an excellent option for bilateral autologous breast reconstruction in women who require significant breast volume but have insufficient abdominal tissue for a bilateral DIEP flap. The bipedicled SHAEP flap allows for enhanced flap perfusion, increased volume, and abdominal contour improvement using a single abdominal donor site. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Optimizing Perforator Selection: A Multivariable Analysis of Predictors for Fat Necrosis and Abdominal Morbidity in DIEP Flap Breast Reconstruction



by Hembd, Austin; Teotia, Sumeet S.; Zhu, Hong; Haddock, Nicholas T.  

Plastic and Reconstructive Surgery: September 2018 - Volume 142 - Issue 3 - p 583–592

Background: This study aims to elucidate the important predicting factors for fat necrosis and abdominal morbidity in the patient undergoing deep inferior epigastric artery perforator flap reconstruction.

 Methods: The authors conducted a retrospective review of 866 free-flap breast reconstructions performed at one institution from 2010 to 2016. Twenty-eight potential predictors were included in multivariable analyses to control for possible confounding interactions.

Results: Four hundred nine total deep inferior epigastric artery perforator flaps were included in the statistical analysis. Of these, 14.4 percent had flap fat necrosis, 21.3 percent had an abdominal wound or complication, and 6 percent had an abdominal bulge or hernia. Analysis showed an increase in the odds of fat necrosis with increasing flap weight (OR, 1.002 per 1-g increase; p = 0.0002). A decrease in the odds of fat necrosis was seen with lateral row (OR, 0.29; p = 0.001) and both medial and lateral row perforator flaps (OR, 0.21; p = 0.001), if indocyanine green angiography was used (OR, 0.46; p = 0.04), and with increasing total flow rate of the flap (OR, 0.62 per 1-mm/second increase; p = 0.05). Increased odds of abdominal bulge or hernia were seen with lateral row or both medial and lateral row perforators (OR, 3.21; p = 0.05) versus medial row perforator-based flaps, and with patients who had an abdominal wound postoperatively (OR, 2.59; p = 0.05).

Conclusions: The authors’ results suggest that using larger caliber perforators and perforators from the lateral row alone, or in addition to medial row perforators, can decrease fat necrosis more than simply harvesting more perforators alone. However, lateral and both medial and lateral row perforator flaps come at the cost of increasing abdominal bulge rates. CLINICAL QUESTION/LEVEL OF EVIDENCE: Risk, III.

The Lumbar Artery Perforator Flap in Autologous Breast Reconstruction: Initial Experience with 100 Cases



by Opsomer, Dries; Stillaert, Filip; Blondeel, Phillip; Van Landuyt, Koenraad  


Plastic and Reconstructive Surgery: July 2018 - Volume 142 - Issue 1 - p 1e–8e

Background: The lumbar artery perforator flap is an alternative flap in breast reconstruction for those patients who are not eligible for a deep inferior epigastric artery perforator (DIEAP) flap. Shaping of this flap is easier compared with other flaps because of the quality of the lumbar fat and the gluteal extension. Methods: Between October of 2010 and June of 2017, a total of 100 lumbar artery perforator free flap breast reconstructions were performed in 72 patients. Patient demographics, indications, flap specifics, and complications were reviewed retrospectively. Results: Twenty-eight bilateral and 44 unilateral breast reconstructions with a lumbar artery perforator flap were performed. Mean patient age was 48 years, and the average body mass index was 23.11 kg/m2. The authors report 43 preventive mastectomies for elevated cancer risk with subsequent immediate reconstruction, 34 secondary reconstructions, and 14 tertiary reconstructions. Mean operative time was 7 hours 4 minutes, including the mastectomy in primary cases. Mean flap weight was 499 g (range, 77 to 1216 g) and mean follow-up time was 30 months. The revision rate was 22 percent and nine flaps were lost. Conclusions: The lumbar artery perforator flap is a valuable alternative to the DIEAP flap in breast reconstructive surgery. It is an excellent flap for BRCA-positive patients who are typically young and have limited excess tissue at the conventional donor sites. Despite higher revision rates compared with the DIEAP flap, the lumbar flap is superior in mimicking the shape and feel of native breast tissue. Scarring at the donor site remains a sore point but can be easily treated and used to an advantage to contour the flanks. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Versatility of the Profunda Artery Perforator Flap: Creative Uses in Breast Reconstruction

Versatility of the Profunda Artery Perforator Flap: Creative Uses in Breast Reconstruction
Haddock, N et al

Plastic & Reconstructive Surgery: March 2017 - Volume 139 - Issue 3 - p 606e–612e

Background: Flaps based on the profunda artery perforators were first used for reconstruction of pressure sores, burn contractures, and extremity wounds. Recently, a revised profunda artery perforator flap was introduced for breast reconstruction. However, the flap is rarely used despite interesting reports on its use. The authors present their experience with the profunda artery perforator flap, describing its versatile applications in breast reconstruction. 
Methods: The authors conducted a retrospective review of all patients of the lead author who underwent breast reconstruction with profunda artery perforator flaps before January of 2015. Patient demographics, perioperative data, and postoperative complications were recorded and analyzed. Results: Seventy-three consecutive profunda artery perforator flaps were used to reconstruct 71 breasts. In 21 breasts, a profunda artery perforator flap was used in conjunction with another flap—with a deep inferior epigastric perforator flap (n = 18), a superior gluteal artery perforator flap (n = 1), or as stacked profunda artery perforator flaps (n = 2). The flap failure rate was 2.7 percent. There was one case of clinically apparent fat necrosis. There were no other major flap complications. Donor-site complications included cellulitis in two thighs (2.7 percent) and minor wound dehiscence in six thighs (8.2 percent). All donor-site complications healed satisfactorily by secondary intention without any additional procedures. 
Conclusions: The profunda artery perforator flap is a safe and versatile option for breast reconstruction. It can be combined with other flaps when additional volume or skin requirements are present. Flap and donor-site complications are comparable to other free tissue breast reconstruction options.

Techniques and Perforator Selection in Single, Dominant DIEP Flap Breast Reconstruction: Algorithmic Approach to Maximize Efficiency and Safety

Techniques and Perforator Selection in Single, Dominant DIEP Flap Breast Reconstruction: 
Algorithmic Approach to Maximize Efficiency and Safety

Mohan, AT et al

Plastic & Reconstructive Surgery November 2016 - Volume 138 - Issue 5 - p 790e–803e

Background: Perforator selection is critical to deep inferior epigastric perforator (DIEP) flap harvest. Commitment to a single perforator has the potential benefit of a simpler dissection, but may increase fat necrosis or perfusion-related complications compared with multiple perforator harvest. 
Methods: A 3-year retrospective study was carried out of all patients who underwent DIEP flap breast reconstruction performed by the senior author (M.S.-C). Data were collected on patient demographics and surgical outcomes.
Results: One hundred eighty-three flaps were performed (105 patients) over 3 years. One hundred fifty-six bilateral (78 patients) and 24 unilateral flaps were included in the final study. Mean age was 47.8 ± 8.4 years and mean body mass index was 29.1 ± 5.3 kg/m2. Seventy-five percent of flaps were based on single dominant perforators. Single perforators were used in 33.3 percent of flaps weighing over 1000 g, 80 and 74 percent of flaps weighing 500 to 1000 g and less than 500 g, respectively (p = 0.01). There were no differences in overall complications between single- versus multiple-perforator DIEP flaps. Neither body mass index nor flap weight posed additional risk to overall complications. Conversion to a muscle-sparing flap was 9.4 percent. 
Conclusions: The authors present an algorithm for perforator selection, stepwise approach to flap harvest, and considerations for intraoperative decision-making in DIEP flap reconstruction. Single–dominant perforator flaps can be safely performed, but inclusion of the largest perforator is critical to flap perfusion. Additional perforators must be weighed against the associated tradeoff with donor-site morbidity. The threshold for conversion to a muscle-sparing flap is reduced with increased clinical experience.

The Profunda Artery Perforator Flap Experience for Breast Reconstruction

The Profunda Artery Perforator Flap Experience for Breast Reconstruction

Allen, R J et al

Plastic & Reconstructive Surgery November 2016 - Volume 138 - Issue 5 - p 968–975

Background: The profunda artery perforator flap was first introduced for breast reconstruction in 2010. In this article, the authors analyze the results of all profunda artery perforator flaps performed by their group to date. Methods: A retrospective review was completed of consecutive profunda artery perforator flaps performed by the senior author (R.J.A.) from 2010 to 2014. Patient demographics, indications, operative techniques, flap specifics, complications, and number of operations were recorded. Results: Ninety-six patients have undergone 164 profunda artery perforator flap operations for breast reconstruction since 2010. Reconstructions were performed following breast cancer management (59.5 percent), following prophylactic mastectomy for cancer risk reduction (35.7 percent), and for congenital breast deformity (4.8 percent). The average age of the patients was 48 years (range, 24 to 64 years) and their average body mass index was 22.5 kg/m2. Average flap weight was 367.4 g and average pedicle length was found to be 10.2 cm. The success rate of the profunda artery perforator flap was greater than 99 percent, with a 3 percent take-back rate and only one flap loss recorded. Complications included hematoma (1.9 percent), seroma (6 percent), fat necrosis (7 percent), and donor-site infection (1.9 percent). Conclusions: The profunda artery perforator flap is an excellent option for breast reconstruction. Advantages include a reliable blood supply, long pedicle, thick donor tissue, and a favorable donor site. Currently, the profunda artery perforator flap is second only to the deep inferior epigastric artery perforator among flaps used by the authors for breast reconstruction.

Using the Retrograde Internal Mammary System for Stacked Perforator Flap Breast Reconstruction: 71 Breast Reconstructions in 53 Consecutive Patients

Using the Retrograde Internal Mammary System for Stacked Perforator Flap Breast Reconstruction: 71 Breast Reconstructions in 53 Consecutive Patients

Plastic & Reconstructive Surgery: February 2016 - Volume 137 - Issue 2 - p 265e–277e doi:10.1097/01.prs.0000475743.08559.b6

Stalder, M
et al



Background: Abdominal tissue is the preferred donor source for autologous breast reconstruction, but in select patients with inadequate tissue, additional volume must be recruited to achieve optimal outcomes. Stacked flaps are an effective approach in these cases, but can be limited by the need for adequate recipient vessels. This article reports outcomes for the use of the retrograde internal mammary system for stacked flap breast reconstruction in a large number of consecutive patients. Methods: Fifty-three patients underwent stacked autologous tissue breast reconstruction with a total of 142 free flaps. Thirty patients underwent unilateral stacked deep inferior epigastric perforator (DIEP) flap reconstruction, five had unilateral stacked profunda artery perforator flap reconstruction, one had bilateral stacked DIEP/superior gluteal artery perforator flap reconstruction, and 17 underwent bilateral stacked DIEP/profunda artery perforator flap reconstruction. In all cases, the antegrade and retrograde internal mammary vessels were used for anastomoses. In situ manometry studies were also conducted comparing the retrograde internal mammary arteries in 10 patients to the corresponding systemic pressures. Results: There were three total flap losses (97.9 percent flap survival rate), two partial flap losses, four reexplorations for venous congestion, and three patients with operable fat necrosis. The mean weight of the stacked flaps for each reconstructed breast was 622.8 g. The retrograde internal mammary mean arterial pressures were on average 76.6 percent of the systemic mean arterial pressures. Conclusions: The results demonstrate that the retrograde internal mammary system is capable of independently supporting free tissue transfer. These vessels provide for convenient dissection and improved efficiency of these cases, with successful postsurgical outcomes.

The Profunda Artery Perforator Flap: Investigating the Perforasome Using Three-Dimensional Computed Tomographic Angiography

The Profunda Artery Perforator Flap: Investigating the Perforasome Using Three-Dimensional Computed Tomographic Angiography
Wong, C et al
Plastic & Reconstructive Surgery: November 2015 - Volume 136 - Issue 5 - p 915–919


Background: The profunda artery perforator flap has been emerging as an alternative method of autologous breast reconstruction. This flap uses upper posterior thigh tissue. The profunda artery perforator perforasome is investigated using three-dimensional computed tomographic angiography.
Methods: Ten cadaveric thighs were dissected centered over the profunda artery perforator. The perforator was injected with contrast medium and the flap was then subjected to computed tomographic scanning using a GE Lightspeed 16-slice scanner. The three-dimensional images were viewed, and measurements were obtained using Aquarius software, including horizontal and vertical extensions of the flap and areas of perfusion. Clinical examples are presented.
 Results: A profunda artery perforator (occasionally two) was consistently found in the upper medial thigh region, posterior to the gracilis muscle. The area of vascularity shown by the spread of contrast extends inferiorly beyond the usual lower border of the profunda artery perforator flap, which is usually 7 cm wide. In injected cadaveric flaps, the mean horizontal dimension was 16.7 cm and the mean vertical dimension was 16.5 cm. The mean area perfused was 8812 cm2. Conclusions: The profunda artery perforator flap is a vascularly sound flap, and is a good option for autologous breast reconstruction. Advantages include a reliable pedicle, no position changes required, and possibly an improved donor-site contour from a thigh lift. It is an excellent alternative to abdominally based free flaps and can also be used in conjunction with other flaps for further volume enhancement.

Nipple-Sparing Mastectomy and Ptosis: Perforator Flap Breast Reconstruction .................

Plastic & Reconstructive Surgery: July 2015 - Volume 136 - Issue 1 - p 1e–9e
doi: 10.1097/PRS.0000000000001325

DellaCroce, Frank J. et al.


Background: Patients with moderate to severe ptosis are often considered poor candidates for nipple-sparing mastectomy. This results from the perceived risk of nipple necrosis and/or the inability of the reconstructive surgeon to reliably and effectively reposition the nipple-areola complex on the breast mound after mastectomy.
Methods: A retrospective review identified patients with grade II/III ptosis who underwent nipple-sparing mastectomy with immediate perforator flap reconstruction and subsequently underwent a mastopexy procedure. The mastopexies included complete, full-thickness periareolar incisions with peripheral undermining around the nipple-areola complex to allow for full transposition of the nipple-areola complex relative to the surrounding skin envelope.
Results: Seventy patients with 116 nipple-sparing mastectomies met inclusion criteria. The most common complications were minor incisional dehiscence (7.7 percent) and variable degrees of necrosis in the preserved breast skin (3.4 percent) after the initial mastectomy. There were no cases of nipple-areola complex necrosis following the secondary mastopexy.
Conclusions: The authors demonstrate that full mastopexy, including a complete full-thickness periareolar incision and nipple-areola complex repositioning on the breast mound, can be safely performed after nipple-sparing mastectomy and perforator flap breast reconstruction. The underlying flap provides adequate vascular ingrowth to support the perfusion of the nipple-areola complex despite complete incisional interruption of the surrounding cutaneous blood supply. These findings may allow for inclusion of women with moderate to severe ptosis in the candidate pool for nipple-sparing mastectomy if oncologic criteria are otherwise met. These findings also represent a significant potential advantage of autogenous reconstruction over implant reconstruction in women with breast ptosis who desire nipple-sparing mastectomy.
