One-Stage Deep Inferior Epigastric Perforator Flap Salvage of Infected Tissue Expanders.

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.

A Multi-institutional Analysis of a Textbook Outcome Among Patients Undergoing Microvascular Breast Reconstruction.

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.

Indocyanine Green Angiography for Detecting Quantitative Perfusion Changes in Deep Inferior Epigastric Perforator Flap Breast Reconstruction With Second Venous Drainage.

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.

Shifting toward total drainless approach in DIEP flap-based breast reconstruction: Evaluation of safety.

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.

'Rosebud' inset of DIEP flap in delayed breast reconstruction for consistent projection, lateral flow, and ptosis.

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.

Projected augmented reality in DIEP flap breast reconstruction: Projecting perforators on the skin using dynamic infrared thermography.

BACKGROUND: Dynamic infrared thermography (DIRT) is a quick and non-invasive technique for perforator mapping in free flaps that provides real-time information. After a cold challenge, areas best supplied with blood become visible hotspots on color-coded maps, indicating perforators. This study presents a proof of principle for a new and innovative feature of DIRT, where projected augmented reality is used to directly display thermal images on the patient's abdomen prior to the deep inferior epigastric artery perforator (DIEP) flap breast reconstruction. METHODS: A self-aligning projection device prototype (Anatomy Projector) equipped with an integrated thermal camera was used to obtain thermal information and project the color-coded map directly on the patient's abdomen before DIEP flap breast reconstruction. Projected DIRT hotspots were verified using a hand-held Doppler, and compared to the vascularity on computed tomography angiography (CTA), and intraoperative perforator measurements following a Cartesian grid. RESULTS: A total of 514 DIRT hotspots were projected in 50 patients, among them 97.3% could be verified using Doppler. The positive predictive value for CTA was 74.5%. Intraoperative measurements yielded 132 perforators in 71 flaps, among them 75 perforators (56.8%) correlated with projected DIRT hotspots, and half of them (54.7%) appeared within the first 5 emerging hotspots. CONCLUSION: This study showed that real-time display of thermal data in DIEP flap breast reconstruction is feasible via projected augmented reality. Projection facilitates convenient marking of hotspots, and a high resemblance to Doppler and CTA data was observed. Further research should assess the added value of projecting thermal images intraoperatively and in other fields of plastic surgery.

Alternatives to the Gold Standard: A Systematic Review of Profunda Artery Perforator and Lumbar Artery Perforator Flaps for Breast Reconstruction.

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.

Inset techniques for the DIEP flap - what improves aesthetic outcomes?

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.

The value of microvascular breast reconstruction: Cost equivalence of TRAM and DIEP flaps implications in the era of CMS reforms.

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.

Breast reconstruction using a superficial inferior epigastric artery flap with pedicle elongation via an arteriovenous loop: A case report.

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.

Simultaneous Co-surgeon Deep Inferior Epigastric Perforator (DIEP) Flap Breast Reconstructions: Feasibility and Clinical Outcomes.

BACKGROUND: A co-surgeon model is known to be favorable in microvascular breast reconstruction, but simultaneous co-surgeon deep inferior epigastric perforator (DIEP) flap cases have not been well-studied. The authors hypothesize that performing two simultaneous co-surgeon bilateral DIEP flap reconstructions results in non-inferior clinical outcomes and may improve patient access to care. METHODS: A single-institution, retrospective cohort study was performed utilizing record review to identify all cases of co-surgeon free-flap breast reconstructions over a 38-month period. Patients who underwent simultaneous bilateral DIEP flap breast reconstructions with the same two co-surgeons were identified. The control group consisted of subjects who underwent non-simultaneous reconstruction by the same co-surgeons within the same, preceding, or following month of those in the study group. Primary outcome variables were 90-day postoperative complications, while secondary outcomes were operating time, ischemia time, and length of stay. Descriptive statistics, univariate and multivariable regression analyses were performed. RESULTS: Overall, 137 subjects were identified and 64 met the inclusion criteria (n = 28 study, n = 36 control). There were no statistically significant differences between groups in body mass index, radiation, trainee experience, flap perforator number, immediate/delayed reconstruction, or length of stay. There were also no statistically significant differences in complications, including flap loss, anastomosis revision, take-back to the operating room, or re-admission. Operative time was longer in the simultaneous DIEP group (540.5 vs. 443.5 min, p < 0.01), but ischemia time was shorter in the simultaneous group (64.0 vs. 80.5 min, p < 0.01). CONCLUSIONS: A simultaneous co-surgeon approach to bilateral DIEP flap reconstruction may improve access to care and does not result in a higher complication rate compared with non-simultaneous bilateral DIEP flaps.

The influence of a previous implant-based breast reconstruction on postoperative sensation of the deep inferior epigastric artery perforator flap.

BACKGROUND: Implants and DIEP flaps have different outcomes regarding postoperative breast sensation. When compared to the preoperative healthy breast, implant-based breast reconstruction (IBBR) negatively influences postoperative breast sensation. However, it is currently unknown whether a prior IBBR also influences postoperative sensation of a replacing DIEP flap. The goal of this cohort study is to evaluate the influence of an IBBR on the postoperative sensation of a replacing DIEP flap. METHODS: Women were included if they received a DIEP flap reconstruction after mastectomy, with or without prior tissue expander (TE) and/or definitive breast implant. Sensation was measured at four intervals in 9 areas of the breast with Semmes-Weinstein monofilaments: T0 (preoperative, implant/no reconstruction), T1 (2-7 months postoperative, DIEP), T2 (± 12 months postoperative, DIEP), Tmax (maximum follow-up, DIEP). Linear mixed-effects models were used to investigate the relationship between an implant/TE prior to the DIEP flap and recovery of breast sensation. RESULTS: 142 women comprising 206 breasts were included. 48 (23.3%) breasts did, and 158 (76.7%) breasts did not have a TE/IBBR prior to their DIEP. No statistically significant or clinically relevant relationships were found between a prior implant/TE and recovery of DIEP flap breast sensation for the flap skin, native skin, or total breast skin at T1, T2, or Tmax. There were also no relationships found after adjustment for the confounders radiation therapy, BMI, diabetes, age, flap weight, follow-up, and nerve coaptation. CONCLUSIONS: An implant/TE prior to a DIEP flap does not influence the recovery of postoperative breast sensation of the DIEP flap.

Impact of Comorbidities on Sensory Return After Breast Reconstruction.

PURPOSE: Breast anesthesia after mastectomy and reconstruction has been an ongoing concern with few improvements made in recent years. At present, there is a lack of studies evaluating the impact of comorbidities on sensation restoration. Identifying risk factors (RF) will be helpful with preoperative counseling. METHODS: This was a prospective study on patients who underwent mastectomy and immediate implant-based or neurotized deep inferior epigastric perforator (DIEP) flap-based reconstruction. Neurosensory testing was performed at predefined time points using a pressure specified device. Patients were stratified based on reconstruction type and comorbidities, including obesity (≥30 kg/m2), age (>55 years), hypertension, alcohol use, and smoking status. Sensory comparisons among the comorbidity groups were conducted using unpaired 2-sample t tests. RESULTS: A total of 239 patients were included in this study with 109 patients in the implant cohort and 131 patients in the DIEP cohort. One patient underwent bilateral reconstruction using both reconstructive modalities. Preoperatively, age older than 55 years was identified as an RF for reduced breast sensation in the implant cohort (difference in threshold, 10.7 g/mm2), whereas obesity was identified as an RF in the DIEP cohort (difference in threshold, 8 g/mm2). During the first 2 years postreconstruction, age older than 55 years and tobacco use history were found to be negatively correlated with breast sensation for both cohorts. With DIEP reconstruction specifically, obesity was identified as an additional RF during the early postoperative period. Of note, none of the comorbidities were found to be long-term RFs for reduced breast sensitivity. All breast sensation levels returned to comparable levels across all comorbidities by 4 years postreconstruction. CONCLUSIONS: Currently, various comorbidities have been recognized as RFs for several postoperative complications including extended postoperative stay, necrosis, infection, and reoperation. However, our findings suggest that, although age, smoking history, and obesity showed transient associations with reduced breast sensation during the initial years postreconstruction, they play no role in the long-term potential of sensory nerve regeneration.

Continuing Insurance Coverage for Flap-Based Breast Reconstruction: Is There a Reservation Cost Related to a Woman's Abdominal Flap Choice?

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.

Effect of corticosteroids on ischemia-reperfusion injury of deep inferior epigastric perforator flap after re-exploration for anastomosis thrombosis: A prospective randomized trial.

Patients undergoing breast reconstruction with the deep inferior epigastric perforator (DIEP) flap are at risk of arterial and venous thrombosis, necessitating flap salvage surgery. However, this carries the risk of ischemia-reperfusion injury (IRI) and potential significant partial or complete flap loss. The objective of this study was to evaluate the potential benefit of corticosteroids in reducing IRI related complications in DIEP flaps that are returned to the operation theater for attempted salvage after venous or arterial failure. A double-blinded prospective randomized study was conducted between January 2012 and January 2023 on patients scheduled for secondary unilateral breast reconstruction using the DIEP flap technique. Patients were included if they developed post-operative venous or arterial flap thrombosis and experienced DIEP flap IRI following operative take-back and anastomosis revision. The treatment group (TG) received a 5-day course of corticosteroids, while the control group (CG) did not receive any specific treatment. Forty-six patients were enrolled in the study. In the CG, two cases of total flap loss and eight cases of partial flap necrosis were observed, while the TG had only 1 case of partial flap necrosis (p < 0.05). The complete resolution of clinical signs of IRI occurred within 13 ± 2.1 days for the TG and 21 ± 3.5 days for the CG (p = 0.00001). The TG had a significantly shorter hospital stay (11.13 ± 0.38 days) compared with the CG (15.47 ± 1.27 days; p < 0.0001). Targeted corticosteroid therapy following a salvage procedure for vascular thrombosis in DIEP flaps has shown promise as an effective treatment for subsequent IRI. This approach may be considered as a viable option for managing IRI in free flaps. However, further studies involving a larger number of patients are required to substantiate our hypothesis.

Secondary solution for breast reconstruction following total DIEP flap loss: A single-center experience after 3270 DIEP flaps.

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.

Reversal in Centers for Medicare & Medicaid Services Reimbursement for Deep Inferior Epigastric Perforator Flap Reconstruction-Empowering Plastic Surgeons in Sustaining Microsurgical Accessibility.

ABSTRACT: This Editorial discusses the recent overturning of a proposed Centers for Medicare & Medicaid Services policy that reduced reimbursement for deep inferior epigastric perforator flap breast reconstruction. The authors highlight the importance of advocacy efforts in sustaining access to complex microsurgical procedures, even those under investigation such as breast reinnervation and lymphatic reconstruction.
