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.

The Role of Antibiotic Prophylaxis in Primary and Secondary Implant-Based Breast Augmentation: A Systematic Review and Meta-Analysis.

BACKGROUND: The administration of antibiotic prophylaxis for implant-based breast augmentation (IBBA) is commonplace among many plastic surgeons. However, the current literature lacks evidence-based recommendations to support this practice. Although few studies have demonstrated a reduction in surgical site infection (SSI) and capsular contracture (CC) with antibiotics, these studies were underpowered and poorly designed. The aim of this study was to provide an updated comprehensive analysis of the literature to revisit the benefit of antibiotic prophylaxis. METHODS: A comprehensive literature search of PubMed, Embase, Web of Science, and Cochrane was performed from January 1989 to January 2022. Observational studies and randomized controlled trials (RCTs) involving primary and secondary IBBA and use of antibiotic prophylaxis were included. Primary outcomes included SSI and CC. Study quality and risk of bias were evaluated using standardized tools. A meta-analysis was performed for eligible studies. Trial Sequential Analysis was used to assess the need for future RCTs. RESULTS: A total of 5 studies (3 observational and 2 RCTs) with 2383 patients were included in this study. Rates of SSI ranged from 0% to 2.3%, whereas CC ranged from 0% to 53%. Antibiotic prophylaxis showed no benefit for both SSI (odds ratio, 1.77; 95% confidence interval, 0.76-4.13) and CC (odds ratio, 0.46; 95% confidence interval, 0.00-45.72). Trial Sequential Analysis demonstrated that further high-quality RCTs are needed. CONCLUSIONS: Antibiotic prophylaxis for IBBA failed to demonstrate improvements in SSI and CC in this comprehensive review. Current evidence was shown to be of low quality because of heterogeneity and high risk for bias. Further high-quality multicentered RCTs are warranted to fully evaluate the role of antibiotic prophylaxis for IBBA.

Using the modified frailty index to predict negative outcomes in free-flap breast reconstruction: A National Surgical Quality Improvement Project-based study.

BACKGROUND: Post-mastectomy free-flap breast reconstruction is becoming increasingly common in the United States. However, predicting which patients may suffer complications remains challenging. We sought to apply the validated modified frailty index (mFI) to free-flap breast reconstruction in breast cancer patients and determine its utility in predicting negative outcomes. METHODS: We conducted a retrospective study using National Surgical Quality Improvement Project (NSQIP). All patients who had a CPT code of 19364, indicative of free tissue transfer for breast cancer reconstruction, were included. Data on preoperative characteristics and postoperative outcomes were collected. Patients were separated based on the number of mFI factors present into three categories: 0, 1, and > 2 factors. Preoperative demographics, clinical status, and other comorbidities were also studied. Negative outcomes were compared using multivariate logistic regression. RESULTS: 11,852 patients (mean age 50.9 ± 9.5) were found; 24.2% had complications, comparable to previous literature. mFI is predictive of all types of negative outcomes. 22.5% of all patients with 0 mFI, 27.7% of patients with 1 mFI and 34.2% of patients with at least two mFI had a negative outcome. The most common factors contributing to the mFI were history of hypertension (24.8%) and diabetes (6.1%). mFI was found to be an isolated risk factor for negative outcomes, along with steroid use, American Society of Anesthesiology (ASA) classification, body mass index, and immediate, and bilateral operations. CONCLUSIONS: This NSQIP-based study for patients undergoing free flap breast reconstruction shows that the mFI holds predictive value regarding negative outcomes. This provides more information to properly counsel patients before free flap breast reconstruction surgery.

The use of negative pressure wound therapy in severe open lower extremity fractures: identifying the association between length of therapy and surgical outcomes.

BACKGROUND: Negative pressure wound therapy (NPWT) is a widely accepted method of temporary coverage for complex lower extremity wounds before definitive reconstruction. However, the precise role of NPWT in the perioperative management of patients with complicated lower extremity injuries remains unclear. In this study, we examine the effect of NPWT on flap complications and overall outcomes based on timing of soft-tissue reconstruction relative to initial injury and implementation of NPWT. METHODS: We retrospectively reviewed the medical records of 32 consecutive patients presenting to a single institution receiving lower extremity reconstruction after Gustilo class IIIB or IIIC open tibial fractures over a 5-y period. Length of hospitalization, number of surgical procedures, flap failure, infection, and nonunion were parameters of interest in this study. RESULTS: The incidence of complications in patients treated with NPWT was lower compared with patients who underwent wet-to-dry dressing changes, regardless of when surgery was performed. The highest rate of complications was observed in patients operated on >6 wk after injury and who received wet-to-dry dressing changes wound care. By comparison, those who underwent surgery within 1 wk of injury and who were bridged with NPWT had the lowest rate of complications. CONCLUSIONS: The use of NPWT therapy in the perioperative management of patients with open lower extremity fractures reduces complication rates associated with limb salvage surgery. Our results suggest that NPWT can be used as a temporizing measure to optimize patients before flap surgery, effectively lengthening the window of opportunity for definitive reconstruction.

A Single-center Comparison of Surgical Outcomes following Prepectoral and Subpectoral Implant-based Breast Reconstruction.

Background: Prepectoral implant placement continues to gain widespread acceptance as a safe and effective option for breast reconstruction. Current literature demonstrates comparable rates of complications and revisions between prepectoral and subpectoral placement; however, these studies are underpowered and lack long-term follow-up. Methods: We performed a retrospective cohort study of patients who underwent immediate two-staged tissue expander or direct-to-implant breast reconstruction at a single center from January 2017 to March 2021. Cases were divided into prepectoral and subpectoral cohorts. The primary outcomes were postoperative complications, aesthetic deformities, and secondary revisions. Descriptive statistics and multivariable regression models were performed to compare the demographic characteristics and outcomes between the two cohorts. Results: We identified 996 breasts (570 patients), which were divided into prepectoral (391 breasts) and subpectoral (605 breasts) cohorts. There was a higher rate of complications (P < 0.001) and aesthetic deformities (P = 0.02) with prepectoral breast reconstruction. Secondary revisions were comparable between the two cohorts. Multivariable regression analysis confirmed that prepectoral reconstruction was associated with an increased risk of complications (odds ratio 2.39, P < 0.001) and aesthetic deformities (odds ratio 1.62, P = 0.003). Conclusions: This study evaluated outcomes in patients undergoing prepectoral or subpectoral breast reconstruction from a single center with long-term follow-up. Prepectoral placement was shown to have an inferior complication and aesthetic profile compared with subpectoral placement, with no difference in secondary revisions. These findings require validation with a well-designed randomized controlled trial to establish best practice for implant-based breast reconstruction.

Same-Day Discharge for Immediate Breast Reconstruction: A National Surgical Quality Improvement Program Study.

BACKGROUND: Patients undergoing immediate breast reconstruction with tissue expanders are frequently admitted after surgery for monitoring and pain control, which introduces additional costs and risks of nosocomial infection. Same-day discharge could conserve resources, mitigate risk, and return patients home for faster recovery. The authors used large data sets to investigate the safety of same-day discharge after mastectomy with immediate postoperative expander placement. METHODS: A retrospective review was performed of patients in the National Surgical Quality Improvement Program database who underwent breast reconstruction using tissue expanders between 2005 and 2019. Patients were grouped based on date of discharge. Demographic information, medical comorbidities, and outcomes were recorded. Statistical analysis was performed to determine efficacy of same-day discharge and identify factors that predict safety. RESULTS: Of the 14,387 included patients, 10% were discharged the same day, 70% on postoperative day 1, and 20% later than postoperative day 1. The most common complications were infection, reoperation, and readmission, which trended upward with length of stay (6.4% versus 9.3% versus 16.8%), but were statistically equivalent between same-day and next-day discharge. The complication rate for later-day discharge was statistically higher. Patients discharged later had significantly more comorbidities than same or next-day discharge counterparts. Predictors of complications included hypertension, smoking, diabetes, and obesity. CONCLUSIONS: Patients undergoing mastectomy with immediate tissue expander reconstruction are usually admitted overnight. However, same-day discharge was demonstrated to have an equivalent risk of perioperative complications as next-day discharge. For the otherwise healthy patient, going home the day of surgery is a safe and cost-effective option, although the decision should be made based on the individual patient. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, III.

Enhanced Recovery after Surgery Protocol Decreases Length of Stay and Postoperative Narcotic Use in Tissue Expander-based Breast Reconstruction.

Background: Enhanced recovery after surgery (ERAS) protocols have demonstrated success in reducing hospital stay and opioid consumption, but are less well studied in patients undergoing tissue expander-based breast reconstruction (TEBR). This study evaluates the effectiveness of an ERAS postoperative protocol for TEBR at a high-volume center. Methods: All patients undergoing immediate tissue expander reconstruction after the introduction of ERAS were prospectively included from April 2019 to June 2023. An equivalent number of similar patients were retrospectively reviewed before this date as the non-ERAS control. Data included demographics, operative details, postoperative length of stay, inpatient and discharge narcotic quantities, inpatient pain assessments, postoperative radiation, and complications within 90 days. Results: There were 201 patients in each cohort with statistically similar demographics. Patients in the ERAS cohort were more likely to undergo prepectoral reconstruction (83.1% versus 4.5%, P < 0.001), be discharged by day 1 (96.5% versus 70.2%, P < 0.001) and consume lower inpatient milligram morphine equivalent (MME) median (79.8 versus 151.8, P < 0.001). Seroma rates (17.4% versus 3.5%, P < 0.001) and hematoma incidence (4.5% versus 0%, P = 0.004) were higher in the ERAS cohort. Adjusting for implant location, ERAS was associated with a 60.7 MME reduction (ß=-60.7, P < 0.001) and a shorter inpatient duration by 0.4 days (ß =-0.4, P < 0.001). Additionally, prepectoral reconstruction significantly decreased MME (ß=-30.9, P = 0.015) and was the sole predictor of seroma development (odds ratio = 5.2, P = 0.009). Conclusions: ERAS protocols significantly reduce opioid use and hospital stay after TEBR.

Impact of mastectomy flap necrosis on prepectoral reconstructive outcomes.

INTRODUCTION: As reconstructive surgeons have increasingly transitioned to the prepectoral plane for prosthetic breast reconstruction, the implications of mastectomy skin flap necrosis have become more concerning. Our goal was to evaluate the effect of skin flap necrosis on reconstructive outcomes in patients undergoing immediate prepectoral breast reconstruction. METHODS: A retrospective review was conducted of patients undergoing immediate two-stage prepectoral reconstruction at a single center with at least 3 months follow-up. Postoperative complications, reconstructive outcome, and time to final implant were compared between patients with and without mastectomy skin necrosis. RESULTS: A total of 301 patients underwent 509 prepectoral breast reconstructions. Forty-four patients (14.6%) experienced postoperative mastectomy skin flap necrosis. Demographic and reconstructive characteristics were similar between the necrosis and no necrosis cohorts. Patients with skin necrosis were more likely to undergo reoperation after tissue expander (64% vs 19%, p < 0.01) and undergo expander replacement (13.6% vs 3.5%, p = 0.02). However, rates of reconstructive failure (6.8% vs 6.2%), major infection (9.1% vs 9.0%), and minor infection (13.6% vs 17.5%) after expander placement were statistically similar. Patients with skin necrosis trended toward longer time before final implant placement, although the difference was not statistically significant (6.5 vs 5.0 months, p = 0.08). There was no difference in complication rates between the necrosis and no necrosis cohort after final implant placement. There was a higher rate of revision surgery after implant placement in the necrosis cohort (12.5% vs 4.1%, p = 0.047). CONCLUSIONS: Mastectomy skin flap necrosis is a concerning postoperative event, particularly in patients with prepectoral prostheses. We observed that patients with skin necrosis experience higher reoperation rates in the expander period, yet have similar infection rates and achieve similar final reconstructive outcomes compared to patients without necrosis.

Impact of Gabapentin on Postoperative Hypotension in Enhanced Recovery after Surgery Protocols for Microvascular Breast Reconstruction.

Background: Enhanced recovery after surgery (ERAS) protocols have been associated with hypotensive episodes after autologous breast reconstruction. Gabapentin (Gaba), a nonopioid analgesic used in ERAS, has been shown to attenuate postoperative hemodynamic responses. This study assesses ERAS's impact, with and without Gaba, on postoperative hypotension after microvascular breast reconstruction. Methods: Three cohorts were studied: traditional pathway, ERAS + Gaba, and ERAS no-Gaba. We evaluated length of stay, inpatient narcotic use [morphine milligram equivalents (MME)], mean systolic blood pressure, hypotension incidence, and complications. The traditional cohort was retrospectively reviewed, whereas the ERAS groups were enrolled prospectively after the initiation of the protocol in April 2019 (inclusive of Gaba until October 2022). Results: In total, 441 patients were analyzed. The three cohorts, in the order mentioned above, were similar in age and bilateral reconstruction rates (57% versus 61% versus 60%). The ERAS cohorts, both with and without Gaba, had shorter stays (P < 0.01). Inpatient MME was significantly less in the ERAS + Gaba cohort than the traditional or ERAS no-Gaba cohorts (medians: 112 versus 178 versus 158 MME, P < 0.01). ERAS + Gaba significantly increased postoperative hypotensive events on postoperative day (POD) 1 and 2, with notable reduction after Gaba removal (P < 0.05). Across PODs 0-2, mean systolic blood pressure was highest in the traditional cohort, followed by ERAS no-Gaba, then the ERAS + Gaba cohort (P < 0.05). Complication rates were similar across all cohorts. Conclusions: Postmicrovascular breast reconstruction, ERAS + Gaba reduced overall inpatient narcotic usage, but increased hypotension incidence. Gaba removal from the ERAS protocol reduced postoperative hypotension incidence while maintaining similar stay lengths and complication rates.

Salvage rates of compromised free flap breast reconstruction after recurrent thrombosis.

BACKGROUND: Microvascular complications after free flap breast reconstruction are devastating problems that increase patient morbidity and potentially lead to flap loss. Yet, there is a dearth of literature about rates of free flap salvage after recurrent vascular thromboses. METHODS: A retrospective review of all patients undergoing microvascular breast reconstruction at UCLA Medical Center from January 1991 to June 2010 was conducted. The incidence of microvascular thrombosis was evaluated and rates of flap salvage and complications were specifically analyzed after a single microvascular revision (Single Event), 2 or more revisions (Multiple Event), and delayed presentation (>2 days) with attempted salvage (Delayed Event). RESULTS: During the study period, 2094 free flap breast reconstructions were evaluated. Of these, 75 (3.6%) flaps suffered a microvascular complication and 16 (0.76%) flaps were lost. The overall salvage rate was 78.7% (59/75) with the highest salvage rate of 95.9% (47/49) for Single Events. Multiple Events had a salvage rate of 53.3% (8/15), whereas Delayed Events had a salvage rate of 27.3% (3/11). The salvage rate decreased with repeated microvascular events (P < 0.01). In the Multiple Event group, vascular conversion (alternate recipient vessel) correlated with improved flap salvage (87.5%), whereas the lack thereof was associated with flap loss (P < 0.001). CONCLUSIONS: The salvage rate of free flap breast reconstruction diminishes dramatically with recurrent microvascular complications, but can be improved with vascular conversion. The salvage rate in cases of delayed presentation is even worse confirming the need for vigilant postoperative monitoring and aggressive intervention in the setting of flap compromise.

Chest wall reconstruction for sternal dehiscence after open heart surgery.

BACKGROUND: Sternal dehiscence is a grave complication after open heart surgery. Sternal debridement and flap coverage are the mainstays of therapy, but no consensus exists regarding the appropriate level of debridement. More recently, the use of vacuum-assisted closure devices has been advocated as a bridge to definitive closure, but indications for use remain incompletely defined. MATERIALS AND METHODS: A retrospective review of all chest wall reconstructions performed from January 2000 to December 2010 was conducted. The type of operative management was evaluated to assess morbidity, mortality, and length of hospital stay. RESULTS: Fifty-four patients underwent chest wall reconstruction for poststernotomy mediastinitis. Of these patients, 24 underwent conservative sternal debridement with flap closure, 24 underwent radical sternectomy including resection of the costal cartilages followed by flap closure, and 6 underwent radical sternectomy with vacuum-assisted closure therapy followed by flap closure in a delayed fashion. There were 15 patients in the conservative group and 8 patients in the radical sternectomy group who developed postoperative complications (62.5% vs 33.3%, P < 0.05). The conservative sternectomy group had more serious complications requiring reoperation compared to the radical sternectomy group (86.7% vs 25.0%, P < 0.05). The most common complication in the former group was flap dehiscence (8/15, 53.3%), whereas that in the latter group was a superficial wound infection (6/8, 75.0%). There was no significant difference in mortality (25.0% vs 25.0%, P > 0.05%) or length of hospital stay. CONCLUSIONS: Radical sternectomy including the costal cartilages is associated with lower rates of surgical morbidity and reoperation, but not mortality.

Sarcopenia Best Predicts Complications in Free Flap Breast Reconstruction.

Breast reconstruction remains a major component of the plastic surgeon's repertoire, especially free-flap breast reconstruction (FFBR), though this is a high-risk surgery in which patient selection is paramount. Preoperative predictors of complication remain mixed in their utility. We sought to determine whether the sarcopenia score, a validated measure of physiologic health, outperforms the body mass index (BMI) and modified frailty index (mFI) in terms of predicting outcomes. Methods: All patients with at least 6-months follow-up and imaging of the abdomen who underwent FFBR from 2013 to 2022 were included in this study. Appropriate preoperative and postoperative data were included, and sarcopenia scores were extracted from imaging. Complications were defined as any unexpected outcome that required a return to the operating room or readmission. Statistical analysis and regression were performed. Results: In total, 299 patients were included. Patients were split into groups, based on sarcopenia scores. Patients with lower sarcopenia had significantly more complications than those with higher scores. BMI and mFI both did not correlate with complication rates. Sarcopenia was the only independent predictor of complication severity when other factors were controlled for in a multivariate regression model. Conclusions: Sarcopenia correlates with the presence of severe complications in patients who undergo FFBR in a stronger fashion to BMI and the mFI. Thus, sarcopenia should be considered in the preoperative evaluation in patients undergoing FFBR.

Enhanced Recovery after Surgery Protocol Decreases Length of Stay and Postoperative Narcotic Use in Microvascular Breast Reconstruction.

Background: Enhanced recovery after surgery (ERAS) protocols have demonstrated efficacy following microvascular breast reconstruction. This study assesses the impact of an ERAS protocol following microvascular breast reconstruction at a high-volume center. Methods: The ERAS protocol introduced preoperative counseling, multimodal analgesia, early diet resumption, and early mobilization to our microvascular breast reconstruction procedures. Data, including length of stay, body mass index, inpatient narcotic use, outpatient narcotic prescriptions, inpatient pain scores, and complications, were prospectively collected for all patients undergoing microvascular breast reconstruction between April 2019 and July 2021. Traditional pathway patients who underwent reconstruction immediately before ERAS implementation were retrospectively reviewed as controls. Results: The study included 200 patients, 99 in traditional versus 101 in ERAS. Groups were similar in body mass index, age (median age: traditional, 54.0 versus ERAS, 50.0) and bilateral reconstruction rates (59.6% versus 61.4%). ERAS patients had significantly shorter lengths of stay, with 96.0% being discharged by postoperative day (POD) 3, and 88.9% of the traditional cohort were discharged on POD 4 (P < 0.0001). Inpatient milligram morphine equivalents (MMEs) were smaller by 54.3% in the ERAS cohort (median MME: 154.2 versus 70.4, P < 0.0001). Additionally, ERAS patients were prescribed significantly fewer narcotics upon discharge (median MME: 337.5 versus 150.0, P < 0.0001). ERAS had a lower pain average on POD 0-3; however, this finding was not statistically significant. Conclusion: Implementing an ERAS protocol at a high-volume microvascular breast reconstruction center reduced length of stay and postoperative narcotic usage, without increasing pain or perioperative complications.

Keeping abreast of shark bite reconstruction: a case report and brief literature review.

Shark attack-related injuries (SARIs) are rare but may result in highly complex wounds requiring reconstruction by plastic surgeons. Here, we present an unusual case of SARI of the breast and briefly review literature on reconstructive management of (1) breast injuries from other large animals and (2) SARIs to other parts of the body. Our patient was a 39-year-old woman who experienced massive bilateral breast tissue loss from a shark attack. After primary surgical wound management, including debridement and washout, the patient underwent completion mastectomy with bilateral deep inferior epigastric perforator flap breast reconstruction. Literature review revealed that reports of animal-related injuries to the breast are rare, with ours being the first on SARI to the breast and the only describing major reconstruction of animal-related breast injury. Literature on reconstruction of non-breast SARI wounds is limited to two case reports describing severe tissue damage akin to that seen in our patient, both necessitating extensive debridement followed by reconstruction. Overall, our findings demonstrate the uniquely devastating damage resulting from SARIs and the value of primary wound management and abdominally based free flaps in successfully reconstructing these wounds. Level of evidence: Level V, therapeutic study.

Cost-volume analysis of deep inferior epigastric artery perforator flaps for breast reconstruction in the United States.

BACKGROUND: Deep inferior epigastric artery perforator flaps are increasingly utilized over other autologous methods of breast reconstruction. We evaluated the relationship between annual hospital volume and costs after breast reconstruction with the deep inferior epigastric artery perforator flap. METHODS: All female patients undergoing elective implant or autologous tissue breast reconstruction were identified using the 2016-2019 Nationwide Readmission Database. Annual hospital volume of deep inferior epigastric artery perforator reconstructions was tabulated and modeled using restricted cubic splines. Institutions were categorized into high- and low-volume based on the inflection point of the spline between annual caseload and costs. The association between high volume status and costs, complications, length of stay, and 30-day nonelective readmission was assessed using multivariable regression. RESULTS: Of an estimated 94,524 patients meeting inclusion criteria, 33,046 (34.6%) underwent deep inferior epigastric artery perforator flap reconstruction. Deep inferior epigastric artery perforator flap utilization increased from 31% in 2016 to 40% in 2019 (P < .001) among inpatient breast reconstructions. High-volume hospitals more frequently performed bilateral reconstructions (43.3 vs 37.7%, P = .021) but had similar rates of concurrent mastectomy (28.7 vs 30.6%, P = .46), relative to low-volume hospitals. The median cost of deep inferior epigastric artery perforator reconstruction was lower ($29,900 [interquartile range: 22,400-37,400] vs $31,600 [interquartile range: 22,500-44,900], P = .036) at high-volume hospitals compared to low-volume. On adjusted analysis, high-volume status was associated a $3,800 (95% confidence interval: -6,200 to -1,400) decrement in hospitalization costs, and reduced odds of perioperative complications (adjusted odd ratio: 0.68 95% confidence interval: 0.54-0.86). High-volume status was not associated with length of stay or likelihood of unplanned readmission. CONCLUSION: The present study demonstrated an inverse cost-volume relationship in deep inferior epigastric artery perforator flap breast reconstruction. In line with goals of value-based health care delivery, our findings may inform referral patterns to suitable centers for deep inferior epigastric artery perforator breast reconstruction.

Postsurgical Outcomes with Meshes for Two-stage Prosthetic Breast Reconstruction in 20,817 Patients.

Use of acellular dermal matrices (ADMs) for tissue expander breast reconstruction remains controversial with an uncertain safety and efficacy profile. This study analyzes the rates and factors for reoperation and postoperative infection in patients who underwent tissue expander breast reconstruction with and without ADM. Methods: Patients who underwent breast reconstruction with and without ADM were identified from the National Surgical Quality Improvement Program database utilizing CPT codes. Covariates included patient demographics, preoperative comorbidities, and operative characteristics, while outcomes of interest were postoperative infection and reoperation. Univariate and multivariate analyses were performed to identify predictors of adverse outcomes. Results: There were 8334 patients in the ADM cohort and 12,451 patients who underwent tissue expander breast reconstruction without ADM. There were significantly fewer reoperations in the non-ADM cohort (5.4%) compared to the ADM cohort (7.7%) (P < 0.0001), with infection and hematoma as the most common etiologies in both cohorts. Surgical infections were also more prevalent in the ADM cohort (4.7%) compared with the non-ADM cohort (3.6%) (P < 0.0001). Univariate and multivariate analysis of the tissue expander breast reconstruction cohort revealed race, obesity, hypertension, smoking status, albumin, and operative time as predictive for infection risk, while race, obesity, hypertension, smoking, albumin, operative time, and age were significant for reoperation. Conclusion: Our study of 20,817 patients revealed significantly higher risk of infection and reoperation in patients who underwent breast reconstruction utilizing ADM versus without ADM. Patients considering ADM for breast reconstruction should engage in discussion with their surgeon about complications, aesthetics, and cost.

Assessment of advanced age as a risk factor in microvascular breast reconstruction.

BACKGROUND: The population of elderly people is the fastest growing population in the United States. Because breast cancer typically affects the elderly population, surgeons will be performing more mastectomies in older patients. In this study, we evaluate the risks of microvascular breast reconstruction as a function of increasing age. METHODS: Between July 2002 and September 2009, a retrospective analysis of 818 free-flap breast reconstructions was used to assess the risk of age on surgical outcomes. Patient comorbidities, the American Society of Anesthesiologists (ASA) classification, and length of hospital stay were used to assess the rates of complications among our age cohorts. RESULTS: Advanced age was not associated with increased complications (P > 0.69). ASA class was a significant predictor of overall complications (P < 0.03) as well as the rate of fat necrosis (P < 0.01) and hematoma (P < 0.001). Flap loss occurred in 1.5% of operations, but there was no difference among the various age groups. Previous surgery was associated with an increased risk of flap loss (P < 0.001), and hypertension also increased the risk of thrombosis (P < 0.04). There was no difference in mean length of hospital stay (4.27 days). CONCLUSIONS: Advanced age should not be considered a risk factor for microvascular breast reconstruction. Because ASA status did predict overall surgical complications, surgeons should consider the patients' overall health status in deciding whether to operate.

Vascular complications and microvascular free flap salvage: the role of thrombolytic agents.

BACKGROUND: Vascular thrombosis with flap loss is the most dreaded complication of microvascular free tissue transfer. Thrombolytic agents such as tissue plasminogen activator have been used clinically for free flap salvage in cases of pedicle thrombosis. Yet, there is a paucity of data in the literature validating the benefit of their use. METHODS: A retrospective review of the breast reconstruction free flap database was performed at a single institution between the years of 1991-2010. The incidence of vascular complications (arterial and/or venous thrombosis) was examined to determine the role of adjuvant thrombolytic therapy in flap salvage. Pathologic examination was used to determine the incidence of fat necrosis after secondary revision procedures. RESULTS: Seventy-four cases were identified during the study period. In 41 cases, revision of the anastamoses was performed alone without thrombolytics with 38 cases of successful flap salvage (92.7%). In 33 cases, anastamotic revision was performed with adjuvant thrombolytic therapy, and successful flap salvage occurred in 28 of these cases (84.8%). Thrombolysis did not appear to significantly affect flap salvage. Interestingly, only two of the salvaged flaps that had received thrombolysis developed fat necrosis, whereas 11 of the nonthrombolysed flaps developed some amount fat necrosis (7.1% vs. 28.9%, P < 0.05). CONCLUSIONS: The decreased incidence of fat necrosis may be attributable to dissolution of thrombi in the microvasculature with the administration of thrombolytics. Although the use of adjuvant thrombolytic therapy does not appear to impact the rate of flap salvage, their use may have secondary benefits on overall flap outcomes.

Review of Outcomes in Prepectoral Prosthetic Breast Reconstruction with and without Surgical Mesh Assistance.

BACKGROUND: In the past decade, surgeons have increasingly advocated for a return to prepectoral breast reconstruction with claims that surgical mesh (including acellular dermal matrix) can reduce complication rates. However, numerous surgical and implant advancements have occurred in the decades since the initial prepectoral studies, and it is unclear whether mesh is solely responsible for the touted benefits. METHODS: The authors conducted a systematic review of all English language articles reporting original data for prepectoral implant-based breast reconstruction. Articles presenting duplicate data were excluded. Complications were recorded and calculated on a per-breast basis and separated as mesh-assisted, no-mesh prior to 2006, and no-mesh after 2006 (date of first silicone gel-filled breast implant approval). Capsular contracture comparisons were adjusted for duration of follow-up. RESULTS: A total of 58 articles were included encompassing 3120 patients from 1966 to 2019. The majority of the included studies were retrospective case series. Reported complication outcomes were variable, with no significant difference between groups in hematoma, infection, or explantation rates. Capsular contracture rates were higher in historical no-mesh cohorts, whereas seroma rates were higher in contemporary no-mesh cohorts. CONCLUSIONS: Limited data exist to understand the benefits of surgical mesh devices in prepectoral breast reconstruction. Level I studies with an appropriate control group are needed to better understand the specific role of mesh for these procedures. Existing data are inconclusive but suggest that prepectoral breast reconstruction can be safely performed without surgical mesh.
