RESUMEN
BACKGROUND: This study aims to compare perfusion dynamics using indocyanine green videoangiography before and after the creation of a second venous anastomosis between the superficial inferior epigastric vein and the retrograde internal mammary vein (IMV) in deep inferior epigastric perforator (DIEP) flap breast reconstructions. METHODS: Indocyanine green videoangiography performed during DIEP flap reconstructions was analyzed prospectively. The areas of interest were above the perforators with the highest intensity (complete perfusion), the most distal lateral edge of the flap (partial perfusion), and the next lowest intensity (ischemic). We compared the zone intensities before and after the second venous anastomosis, assessing venous drainage patency and functionality. Patient characteristics, operative details, and complications were collected. RESULTS: Seven patients (10 breasts) underwent DIEP reconstruction. Mean age was 54.5 ± 12.4 years. Mean operative duration was 575.5 ± 172.6 minutes. Donors included DIEV (n = 10, 100.0%), superficial inferior epigastric vein (n = 9, 90.0%), and superficial circumflex epigastric vein (n = 1, 10.0%). All DIEVs were anastomosed to the antegrade IMV (n = 10, 100.0%). Superficial inferior epigastric veins were anastomosed to the retrograde IMV (n = 10, 100.0%). Mean peak intensities of the complete perfusion zone before and after the second venous anastomosis were 160.7 ± 42.1 and 188 ± 42.1, respectively ( P = 0.163). Mean peak intensities of the partial perfusion zone were 100.8 ± 21.5 and 152 ± 31.5, respectively ( P < 0.001). Mean peak intensities of the ischemic zone were 90.4 ± 37.4 and 143.4 ± 45.3, respectively ( P = 0.012). CONCLUSION: These findings highlight the potential benefits of the super drainage technique in enhancing perfusion and reducing complications, emphasizing the need for further investigation and consideration of this technique in clinical practice.

With increasing interest in swift postoperative recovery, there has been a trend toward omitting drains in deep inferior epigastric perforator (DIEP) flap-based breast reconstruction, ideally aiming to avoid drains in the breasts and abdomen. This study evaluated our transition toward total drainless reconstruction, focusing specifically on the safety of omitting drains in the breasts. Patients who underwent breast reconstruction with DIEP flap from 2018 to 2023 were reviewed. They were divided into 3 groups: group A (with drains in the abdomen and breast), group B (drains only in the breast), and group C (total drainless). For group C, routine ultrasound examinations were performed to check for fluid accumulation. Complication profiles were compared among the groups. In total, 294 cases were included, comprising 77 in group A, 112 in group B, and 105 in group C. Chronologically, a gradual increase in the proportion of cases in group C was observed, with the complication rates remaining stable. On comparing the complication profiles of the recipient and donor sites among the 3 groups, no significant differences were found. Breast seroma, persisting 1 month postoperatively, was exclusively detected in 6 (5.7%) cases within group C, all of whom were treated with outpatient clinic-based aspiration. When restricting the analysis to group C, a greater weight of mastectomy specimen and axillary lymph node dissections exhibited an independent association with breast seroma development. Smooth transition to total drainless DIEP breast reconstruction appears safe, without significantly increasing the risks of complication.

BACKGROUND: Tissue expander-based breast reconstruction is associated with high rates of infectious complications, often leading to tissue expander explants and delays in receipt of definitive breast reconstruction and adjuvant therapy. In this study, we describe a single-stage technique where deep inferior epigastric artery perforator (DIEP) flaps are used to salvage actively infected tissue expanders among patients originally planning for free flap reconstruction. METHODS: In this technique, patients with tissue expander infections without systemic illness are maintained on oral antibiotics until the day of their DIEP flap surgery, at which time tissue expander explant is performed in conjunction with aggressive attempt at total capsulectomy and immediate DIEP flap reconstruction. Patients are maintained on 1-2 weeks of oral antibiotics tailored to culture data. Patients undergoing this immediate salvage protocol were retrospectively reviewed, and complications and length of stay were assessed. RESULTS: In a retrospective series, a total of six consecutive patients with culture-proven tissue expander infections underwent tissue expander removal and DIEP flap reconstruction in a single stage and were maintained on 7-14 days of oral antibiotics postoperatively. Within this cohort, no surgical site infections, microvascular complications, partial flap losses, reoperations, or returns to the operating room were noted within a 90-day period. CONCLUSIONS: Among a select cohort of patients, actively infected tissue expanders may be salvaged with free flap breast reconstruction in a single surgery with a low incidence of postoperative complications. Prospective studies are needed to evaluate the influence of this treatment strategy on costs, number of surgeries, and dissatisfaction after staged breast reconstruction complicated by tissue expander infections.

BACKGROUND: Individual outcomes may not accurately reflect the quality of perioperative care. Textbook outcomes (TOs) are composite metrics that provide a comprehensive evaluation of hospital performance and surgical quality. This study aimed to investigate the prevalence and predictors of TOs in a multi-institutional cohort of patients who underwent breast reconstruction with deep inferior epigastric artery perforator flaps. METHODS: For autologous reconstruction, a TO was previously defined as a procedure without intraoperative complications, reoperation, infection requiring intravenous antibiotics, readmission, mortality, systemic complications, operative duration ≤12 hours for bilateral and ≤10 hours for unilateral/stacked reconstruction, and length of stay (LOS) ≤5 days. We investigated associations between patient-level factors and achieving a TO using multivariable regression analysis. RESULTS: Of 1000 patients, most (73.2%) met a TO. The most common reasons for deviation from a TO were reoperation (9.6%), prolonged operative time (9.5%), and prolonged LOS (9.2%). On univariate analysis, tobacco use, obesity, widowed/divorced marital status, and contralateral prophylactic mastectomy or bilateral reconstruction were associated with a lower likelihood of TOs (P < 0.05). After adjustment, bilateral prophylactic mastectomy (odds ratio [OR], 5.71; P = 0.029) and hormonal therapy (OR, 1.53; P = 0.050) were associated with a higher likelihood of TOs; higher body mass index (OR, 0.91; P = <0.001) was associated with a lower likelihood. CONCLUSION: Approximately 30% of patients did not achieve a TO, and the likelihood of achieving a TO was influenced by patient and procedural factors. Future studies should investigate how this metric may be used to evaluate patient and hospital-level performance to improve the quality of care in reconstructive surgery.

Here we describe a template of DIEP flap inset that prioritises projection, lateral flow and natural ptosis; key elements of an aesthetically successful delayed breast reconstruction. By not excising the full length of the mastectomy scar, and preserving the scar laterally, we increase the 3-dimensional aesthetic of the breast, moving the final reconstructed breast aesthetic further away from an unintentional 2-dimensional resurfacing. Through controlling the initial take-off around the whole circumference of the breast footprint, a favourable and durable breast conus is consistently achieved. This technique employs designated segments of comparatively more rigid irradiated mastectomy skin flaps, to positively influence reconstructed breast aesthetics at the time of flap inset. Conceptually, this reminds the authors of how the green sepals of a rose shape the bud of petals.

INTRODUCTION: The deep inferior epigastric perforator (DIEP) flap is widely considered as the gold standard in breast reconstruction. The inset technique of the DIEP flap is crucial in determining the overall aesthetic outcome; however, to date no systematic review is available that comprehensively assesses the various techniques. Evaluation of topic: A systematic review was performed according to the PRISMA guidelines. The methodology is outlined within our published protocol (Prospero CRD42023449477). Included articles met a minimal criterion compromising of the intervention (DIEP free flap for breast reconstruction) and outcomes (aesthetic and clinical outcomes). Six articles were included in this review, with a total of 346 patients and a follow-up ranging from 6 months to 4 years. Four articles were of a prospective case series study design, one article was a randomized controlled trial, and one article was a case-control study. The risk of bias was assessed to be high in the case series, but low and moderate in the randomized controlled trial and case-control study respectively. CONCLUSION: Although limited by the quality of the evidence, the single aesthetic unit principle, dual-plane inset, elimination of the need for a skin paddle, appropriate flap positioning and rotation, and algorithmic in-setting may all improve the aesthetic outcome of DIEP free flaps.

INTRODUCTION: Breast reconstruction with the deep inferior epigastric perforator (DIEP) flap is the current gold-standard autologous option. The profunda artery perforator (PAP) and lumbar artery perforator (LAP) flaps have more recently been described as alternatives for patients who are not candidates for a DIEP flap. The aim of this study was to review the survival and complication rates of PAP and LAP flaps, using the DIEP flap as a benchmark. METHODS: A literature search was conducted using PubMed, MEDLINE, Embase, BIOSIS, Web of Science, and Cochrane databases. Papers were screened by title and abstract, and full texts reviewed by three independent blinded reviewers. Quality was assessed using MINORS criteria. RESULTS: Sixty-three studies were included, for a total of 745 PAP, 62 stacked PAP, 187 LAP, and 23,748 DIEP flap breast reconstructions. The PAP (98.3%) had comparable success rate to DIEP (98.4%), and the stacked PAP (88.7%) and LAP (92.5%) success rate was significantly lower (P < 0.0001). The PAP and LAP groups both had a low incidence of fat necrosis. However, the revision rate for the LAP group was 16.1% whereas the PAP group was 3.3%. Donor site wound dehiscence rate was 2.9 in the LAP group and 9.1% in the PAP group. CONCLUSIONS: Profunda artery perforator and DIEP flaps demonstrate very high rates of overall survival. The LAP flap has a lower survival rate. This review highlights the survival and complication rates of these alternative flaps, which may help clinicians in guiding autologous reconstruction technique when a DIEP flap is unavailable.

BACKGROUND: Recent CMS billing changes have raised concerns about insurance coverage for deep inferior epigastric perforator (DIEP) flap breast reconstruction. This study compared the costs and utilization of transverse rectus abdominis myocutaneous (TRAM), DIEP, and latissimus dorsi (LD) flaps in breast reconstruction. METHOD: The study utilized the National Inpatient Sample database to identify female patients who underwent DIEP, TRAM, and LD flap procedures from 2016 to 2019. Key data such as patient demographics, length of stay, complications, and costs (adjusted to 2021 USD) were analyzed, focusing on differences across the flap types. RESULTS: A total of 17,770 weighted patient encounters were identified, with the median age being 51. The majority underwent DIEP flaps (73.5%), followed by TRAM (14.2%) and LD (12.1%) flaps. The findings revealed that DIEP and TRAM flaps had a similar length of stay (LOS), while LD flaps typically had a shorter LOS. The total hospital charges to costs using cost-to-charge ratio were also comparable between DIEP and TRAM flaps, whereas LD flaps were significantly less expensive. Factors such as income quartile, primary payer of hospitalization, and geographic region significantly influenced flap choice. CONCLUSION: The study's results appear to contradict the prevailing notion that TRAM flaps are more cost-effective than DIEP flaps. The total hospital charges to costs using cost-to-charge ratio and hospital stays associated with TRAM and DIEP flaps were found to be similar. These findings suggest that changes in the insurance landscape, which may limit the use of DIEP flaps, could undermine patient autonomy while not necessarily reducing healthcare costs. Such policy shifts could favor less costly options like the LD flap, potentially altering the landscape of microvascular breast reconstruction.

Superficial inferior epigastric artery (SIEA) flap is often chosen to minimize postoperative complications such as abdominal pain and bulging. However, drawbacks, including a small diameter and a short pedicle, pose challenges in anastomosing or creating the lower pole of the breast. Here, we report a case of breast reconstruction using an SIEA flap with pedicle elongation via an arteriovenous loop (AV-loop) using a contralateral superficial inferior epigastric vein (SIEV) graft. A 49-year-old woman underwent a left total mastectomy with the primary insertion of a tissue expander. Breast reconstruction using an SIEA flap with pedicle elongation was planned. The running pattern, pedicle length, and diameter of bilateral SIEA/SIEV and superficial circumflex iliac artery and vein (SCIA/SCIV) were evaluated preoperatively using a 48-MHz probe of ultra-high-frequency ultrasonography (Vevo MD ultrasound device, Fujifilm Visual Sonics, Amsterdam, the Netherlands). During the flap harvesting, the contralateral SIEV graft was harvested to create an AV-loop for pedicle elongation. The 9 cm graft was anastomosed to the left internal mammary artery and vein (IMA/IMV). After the flap elevation, the created AV-loop was divided at the midpoint and anastomosed to the pedicle of the SIEA flap. The SIEA flap, extended with a SIEV AV-loop, facilitated the augmentation of the lower pole of the breast without the risk of pedicle kinking and pulling. The postoperative course was uneventful, and the patient was discharged on postoperative day 7. The prolonged pedicle length via an AV-loop prevents the pedicle kinking and allows for positioning the flap more freely, resulting in an aesthetically good breast contour by filling in the lower pole. The precise preoperative evaluation of the vessels using ultra-high-frequency ultrasonography facilitated meticulous planning. In cases where surgeons aim to minimize intraoperative and postoperative complications associated with other abdominal free flaps, this method may be considered a viable and promising option.

BACKGROUND: The recent proposed alterations to the Centers for Medicare and Medicaid Services regulations, although subsequently reversed on August 21, 2023, have engendered persistent concerns regarding the impact of insurance policies on breast reconstruction procedures coverage. This study aimed to identify factors that would influence women's preferences regarding autologous breast reconstruction to better understand the possible consequences of these coverage changes. METHODS: A survey of adult women in the United States was conducted via Amazon Mechanical Turk to assess patient preferences for breast reconstruction options, specifically deep inferior epigastric perforator (DIEP) and transverse rectus abdominis myocutaneous (TRAM) flap surgery. The Cochrane-Armitage test evaluated trends in flap preferences concerning incremental out-of-pocket payment increases. RESULTS: Of 500 total responses, 485 were completed and correctly answered a verification question to ensure adequate attention to the survey, with respondents having a median (interquartile range) age of 26 (25-39) years. When presented with the advantages and disadvantages of DIEP versus TRAM flaps, 78% of respondents preferred DIEP; however, as DIEP's out-of-pocket price incrementally rose, more respondents favored the cheaper TRAM option, with $3804 being the "indifference point" where preferences for both procedures converged (P < 0.001). Notably, respondents with a personal history of breast reconstruction showed a higher preference for DIEP, even at a $10,000 out-of-pocket cost (P = 0.04). CONCLUSIONS: Out-of-pocket cost can significantly influence women's choices for breast reconstruction. These findings encourage a reevaluation of emergent insurance practices that could potentially increase out-of-pocket costs associated with DIEP flaps, to prevent cost from decreasing equitable patient access to most current reconstructive options.

BACKGROUND: Total deep inferior epigastric perforator (DIEP) flap failure is a significant concern in autologous breast reconstruction. Literature on secondary reconstruction options following total flap failure is limited. This study outlines the outcomes of patients who underwent reconstruction post-DIEP flap failure at our institution. METHODS: We conducted a retrospective analysis of patients receiving autologous breast reconstruction between 2004 and 2021. We aimed to identify causes of total DIEP flap failure, outcomes of revision surgery, and outcomes of secondary breast reconstruction procedures. RESULTS: From 2004 to 2021, 3456 free flaps for breast reconstruction were performed, with 3270 being DIEP flaps for 2756 patients. DIEP flap failure was observed in 40 cases (1.22%). Bilateral reconstructions had a higher failure rate (2.31%) than unilateral (0.72%). The primary cause was intraoperative complications during flap harvest (18 cases), followed by insufficient arterial perfusion (seven cases). Other causes included postoperative hematoma (seven cases), venous congestion (six cases), and late-onset fat necrosis (two cases). Post-failure, five patients received a second free flap with three cases of repeated flap failure. Twenty patients received implant-based reconstruction with two cases of reconstruction failure, while seven patients received a pedicled latissimus dorsi (LD) flap reconstructions with no cases of reconstruction failure. Eight patients declined further reconstruction. CONCLUSION: A second free flap post-DIEP failure was associated with a high risk of reconstruction failure, suggesting the need for careful patient selection. Implant-based and pedicled LD flap seem to be reliable secondary reconstruction options.

BACKGROUND: Robotic-assisted harvest of the deep inferior epigastric perforator (DIEP) flap is an innovative modification of the traditional open preparation for autologous breast reconstruction. It is assumed that donor-site morbidity (herniae, bulging) is reduced by minimising the fascial incision length in robotic-assisted DIEP flap harvest. MATERIAL & METHODS: This is the first report of a robotic-assisted DIEP harvest in Germany, which was performed in April 2023 at the University Hospital of Freiburg in an interdisciplinary approach of the Departments of Plastic Surgery, Urology and Gynaecology. To determine the value of this novel technique, we assessed the demand by retrospectively performing an analysis of potential patients and conducted a cost analysis based on the breast reconstructions with DIEP flap harvest performed between April 2021 and May 2023 at the Department of Plastic Surgery at Freiburg University Hospital. To this end, we carried out a retrospective analysis of preoperative CT angiographies to determine the proportion of patients suitable for a robotic-assisted procedure in a post-hoc analysis. Furthermore, we describe the basic robotic-assisted techniques and discuss the TEP and TAPP laparoscopic approaches. RESULTS: In line with the previously published literature, a short intramuscular course (≤25 mm) and a perforator diameter of≥1.5 mm and≥2.7 mm (subgroup) were defined as a crucial condition for the robotic-assisted procedure. We analysed 65 DIEP flaps harvested in 51 patients, of which 26 DIEP flaps in 22 patients met both criteria, i. e.≤25 mm intramuscular course and≥1.5 mm diameter of the perforator, while 10 DIEP flaps in 10 patients additionally met the criteria of the subgroup (≥2.7 mm diameter). Based on the intramuscular course of the perforators in the CT angiographies of those 26 DIEP flaps, a potential reduction of the fascial incision of 96.8±25.21 mm (mean±standard deviation) compared with the conventional surgical approach was calculated. The additional material costs in our case were EUR 986.01. However, ischaemia time was 33,5 minutes longer than the median of the comparative cohort. CONCLUSION: The robotic-assisted procedure has already proven to be a feasible alternative in a suitable patient population. However, further studies are needed to confirm that robotic-assisted DIEP flap harvest actually reduces harvest site morbidity and thereby justifies the additional costs and complexity.

BACKGROUND: With the success of free autologous breast reconstruction, the abdominal donor site is now an important consideration, especially in patients of childbearing age. In our institution, there are increasing patients who have successfully undergone the deep inferior epigastric artery perforator (DIEP) flap despite previous pregnancy. This study aims to answer questions on the effect of the donor site on pregnancy and vice versa. METHODS: A retrospective cohort study was conducted to identify breast cancer patients who received a free DIEP flap for breast reconstruction from January 2018 to August 2020. Patients were allocated to two groups according to whether they had prior pregnancies with successful deliveries. Demographics, flap-related parameters, surgical outcomes on breast and abdomen, and patient-reported outcome (Breast-Q questionnaire) were analyzed. Patients were excluded if follow-up time was less than 1 year, or if there was incomplete medical records or Breast-Q replies. RESULTS: Ninety-nine of 116 patients had had successful pregnancies with delivery, 17 of them remained nulliparous. No statistically significant differences existed between groups regarding demographic data, flap-related parameters, surgical outcomes on breast and abdomen. Nulliparous patients exhibited significantly lower score in physical well-being in the abdomen domain compared with delivery-experienced patients (62.1 vs. 73.4, p = 0.025). Significantly, nulliparous patients felt more tightness and pulling of the abdominal wall than the delivery-experienced patients (2.9 vs. 3.7; p = 0.05 and 3.5 vs. 4.0; p = 0.04). CONCLUSION: Free DIEP flap can be transferred safely in nulliparous patients despite a slight increase in abdominal tightness and abdominal pulling. Precise flap design and surgical approaches may help to minimize the abdominal discomfort especially on young, normal body mass index, and nonchildbearing patients.

BACKGROUND: Autologous breast reconstruction provides higher satisfaction than implant-based reconstruction in women with low body mass index (BMI). However, the accepted standard of microvascular breast reconstruction, the deep inferior epigastric perforator (DIEP) flap, can be challenging to achieve due to the paucity of adnominal bulk in these patients. This study compared operative outcomes in women with BMI less than 23.5 following reconstruction after one of three free flap methods: the DIEP flap, alternative flaps (ie, lumbar artery perforator flap or profounda artery perforator flap), and stacked flaps. METHODS: A retrospective study was conducted on thin patients (BMI <23.5) who underwent autologous breast reconstruction between 2010 and 2021 by two senior authors (N.T.H. and S.S.T.) at a single institution. One hundred fifteen patients were divided into three reconstructive groups. Flap weights, complication rates, secondary revisions, and fat grafting in each group were then compared. RESULTS: The success rate in all three groups was 100%, with only one partial flap loss in the stacked group. There was a significant difference in overall minor complications and donor complications among the three groups, with alternative flaps experiencing the most. All three groups had similar incidences of recipient breast complications, medical complications, need for secondary revisions, and amount of fat grafted. CONCLUSIONS: Autologous breast reconstruction in low BMI patients yields successful and durable results. This study shows that predictable results in the thin patient population can be obtained via alternate autologous methods beyond the standard DIEP flap. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

BACKGROUND: Many methods to predict the amount of tissue needed for breast reconstruction have been reported, but some require complicated software and special systems. The purpose of this report was to present a simpler method for predicting the volume required for deep inferior epigastric artery perforator (DIEP) flaps. The accuracy of this method was evaluated based on both actual flap design and computed tomography. METHODS: The weight and horizontal (x cm) and vertical (y cm) lengths of the DIEP flap were recorded, and the maximum thickness of subcutaneous tissue (z cm) was measured from computed tomography in 36 cases of breast reconstruction using DIEP flap in our hospital performed between January 2019 and December 2020. Flap volume was calculated using three methods of approximation: triangular prisms using physical and CT measurements (1/2xyz cm3 ); quadrangular and triangular prisms using physical and CT measurements (3/4xyz cm3 ); and a previously reported method using measurements from CT angiography alone and calculation with a standard mathematical formula. These three groups were compared using Bland-Altman plots and intraclass correlation coefficients (ICCs) to assess consistency between predicted and measured values. RESULTS: On Bland-Altman plots, values were distributed almost randomly around the average value of the difference, and no proportional error was evident in the methods. The ICC between predicted and actual values of triangular prisms using physical and CT measurements was largest: ICC (1, 2) = 0.978 (0.825-0.981; 95% confidence interval for ICC). A sufficient flap volume was able to be transplanted in all cases. CONCLUSION: The methods presented appear useful to calculate flap volume closer to the measured value without complicated software systems. These results suggest that the method using two symmetric triangular prisms could predict volume more easily than previously reported methods and may facilitate good breast reconstruction.

SUMMARY: The lumbar artery perforator flap is a valuable alternative in breast reconstruction whenever the deep inferior epigastric perforator flap is not feasible because of insufficient or unavailable abdominal tissue. The advantage is the ideal shape and consistency of the flap, in addition to the option to perform a nerve anastomosis with the cluneal nerve. The anatomy is consistent, but there are some technical issues related to the short perforator and difficult surgical exposure in the lower back region. The inclusion of a vascular interposition graft improved the authors' results and facilitated their technical challenges and final inset of the flap. These videos guide the surgeon through the different steps involved in a breast reconstruction with the lumbar artery perforator flap.

[English] Deep inferior epigastric artery perforator (DIEP) or muscle-sparing transverse rectus abdominis muscle (ms-TRAM) flaps remain the gold standard for autologous reconstruction in post-mastectomy patients, although many women may not be candidates for abdominally based free tissue transfer. In this scenario, there are several other donor site options based from the thigh (transverse and diagonal upper gracilis flaps, profunda artery perforator flap, lateral thigh flap), trunk (lumbar artery perforator flap), and buttock (superior and inferior gluteal artery perforator flaps). This article will provide insight into the history, relevant anatomy, surgical technique and novel applications (neurotization) for alternative flaps in autologous breast reconstruction.
