Tissue Transfer For Breast Reconstruction Research Articles

Management after flap failure: a narrative review

Autologous free tissue transfer for breast reconstruction is a well-established and reliable form of reconstruction for women undergoing mastectomies. These surgeries are performed with high rates of success; however, the consequences of flap failure can be devastating to patients and surgeons. Breast reconstruction decision making following flap loss is a uniquely individualized process, based on considerations of safety, patient goals and preferences, as well as the surgeon’s skillset. The first priority following flap failure is to provide thoughtful patient counseling and support through this difficult time. The aims of reconstruction salvage after flap loss are to excise unhealthy tissue and restore a breast mound of normal anatomical shape. We present an algorithm as a possible approach to managing flap failures. We also review the management of breast reconstruction following free flap failure, including the role of hematologic investigation, anticoagulation recommendations and secondary or tertiary reconstruction with both prosthetic and autologous techniques.

Closed-Incision Negative Pressure Therapy Prevents Major Abdominal Donor-Site Complications in Autologous Breast Reconstruction.

Outcomes in autologous breast reconstruction continue to improve with refinements in microsurgical techniques; however, donor-site morbidity remains a concern. Closed-incision negative pressure therapy (ciNPT) has been shown to reduce wound complications. Limited evaluation in abdominal donor sites has shown promising results. We hypothesize that ciNPT will reduce abdominal donor-site complications. A retrospective chart review was performed of patients who underwent abdominally based autologous free tissue transfer for breast reconstruction by 4 microsurgeons at an academic institution from 2015 to 2020. The application of a commercial ciNPT for donor-site management was at the discretion of the operating surgeon. Demographics, operative details, and management of donor-site complications were analyzed. Four hundred thirty-three patients underwent autologous breast reconstruction; 212 abdominal donor sites were managed with ciNPT and 219 with standard dressings. Demographics were statistically similar between groups. Abdominal wound healing complications were noted in 30.2% of ciNPT patients (64/212) and 22.8% of control patients (50/219, P = 0.08); however, overall wound complications were attributed to obesity on multivariable analysis. Closed-incision negative pressure therapy significantly decreased complications requiring reoperation (ciNPT 6.2%, 4/64; control 26.5%, 13/51; P = 0.004). There were no significant differences in surgical site infection rates (P = 0.73) and rates of abdominal scar revisions (ciNPT 11.8%, 25/212; control 9.1%, 20/219; P = 0.37). Use of ciNPT in abdominal donor-site management significantly decreases the incidence of delayed wound healing requiring surgical intervention, with one major wound healing complication prevented for every 6 donor sites managed with ciNPT.

Estimation of Hemi-Abdominal-Based Free Flap Weight Using Two Computed Tomography-Derived Measurements.

Accurate flap weight estimation is crucial for preoperative planning in microsurgical breast reconstruction; however, current flap weight estimation methods are time consuming. It was our objective to develop a parsimonious and accurate formula for the estimation of abdominal-based free flap weight. Patients who underwent hemi-abdominal-based free tissue transfer for breast reconstruction at a single institution were retrospectively reviewed. Subcutaneous tissue thicknesses were measured on axial computed tomography angiograms at several predetermined points. Multivariable linear regression was used to generate the parsimonious flap weight estimation model. Split-sample validation was used to for internal validation. A total of 132 patients (196 flaps) were analyzed, with a mean body mass index of 31.2 ± 4.0 kg/m2 (range: 22.6-40.7). The mean intraoperative flap weight was 990 ± 344 g (range: 368-2,808). The full predictive model (R 2 = 0.68) estimated flap weight using the Eq. 91.3x + 36.4y + 6.2z - 1030.0, where x is subcutaneous tissue thickness (cm) 5 cm lateral to midline at the level of the anterior superior iliac spine (ASIS), y is distance (cm) between the skin overlying each ASIS, and z is patient weight (kg). Two-thirds split-sample validation was performed using 131 flaps to build a model and the remaining 65 flaps for validation. Upon validation, we observed a median percent error of 10.2% (interquartile range [IQR]: 4.5-18.5) and a median absolute error of 108.6 g (IQR: 45.9-170.7). We developed and internally validated a simple and accurate formula for the preoperative estimation of hemi-abdominal-based free flap weight for breast reconstruction.

945 Elective Autologous Free Tissue Transfer for Breast Reconstruction During the Covid-19 Pandemic: A Comparative Analysis of Outcomes

Abstract Introduction The demand placed on the National Health Service by Covid-19 has led to increased delays on elective surgery. Despite these challenges, our unit was the first centre in the UK to recommence elective breast reconstruction following the development of an evidence-based pathway to select low-risk patients. An enhanced recovery protocol was introduced to reduce length of stay. The aim of this study was to compare post-operative outcomes between our Pre-Covid group and our Covid-group of free tissue transfer breast reconstruction. Method We retrospectively reviewed autologous free tissue transfer breast reconstruction within our department between January 15th and September 27th 2020. Comparative data was split into two groups. A ‘pre-Covid group’ from 15th January to 12th March 2020 and a ‘Covid group’ from 3rd June to 27th September 2020. Both groups contained 15 patients. Operative notes and case notes were reviewed. Length of stay, haematoma-rate, flap failure, infection, fat necrosis, ischaemic time, re-do anastomosis and return-to-theatre were compared. Results Average length of stay was reduced from 4 to 3 days amongst our Covid group, haematoma rate was 7% pre-Covid and 13% during Covid. There was no evidence of flap failure, fat necrosis and donor site dehiscence in either group. Infection and flap dehiscence were 7% pre-Covid and 0% during Covid. Re-do anastomosis was 20% pre-Covid and 7% during Covid. Conclusions No statistically significant changes in outcomes were identified. This early review suggests that elective breast reconstructive surgery can still be achieved with comparable outcomes, despite the added challenges of Covid-19.

Breast reconstruction during the COVID-19 pandemic: A systematic review.

Background:The novel coronavirus disease 2019 (COVID-19) has changed people's way of life and posed great challenges to plastic surgery. Most of plastic surgeries are considered elective surgeries and are recommended to be delayed. But breast reconstruction in plastic surgery is special. Doctors’ associations from different countries have different rules on whether breast reconstruction surgery should be delayed. For the controversial topic of immediate breast reconstruction in the COVID-19 pandemic, we conducted this study.Methods:We searched English databases such as PubMed, Cochrane Library, and Embase. The publication time of papers was set to be from the establishment of the databases to February 2021. All studies on immediate breast reconstruction in the COVID-19 pandemic were included in our study.Results:A total of 6 studies were included in this study. Four studies recommended the use of breast implants or tissue expansion for breast reconstruction surgery and had good results in their clinical practice. In addition, 1 study planned to use autologous free tissue transfer for breast reconstruction, and 1 study planned to use microsurgical techniques for breast reconstruction. But these 2 technologies are still in the planning stage and have not yet been implemented.Conclusions:In our opinion, breast cancer surgery belongs to confine operation, and breast reconstruction surgery should be performed immediately after the completion of breast cancer surgery. We recommend the use of breast implants for breast reconstruction surgery during the COVID-19 epidemic. Due to the limitations of the study, our proposed protocol for breast reconstruction surgery during the COVID-19 epidemic needs to be further validated in clinical studies.

Comparison of the Pedicled Latissimus Dorsi Flap with Immediate Fat Transfer versus Abdominally Based Free Tissue Transfer for Breast Reconstruction.

Abdominally based free tissue transfer (FTT) and latissimus dorsi and immediate fat transfer (LIFT) procedures are both fully autologous options for breast reconstruction. The former is specialized and requires comfort with microsurgical technique, whereas LIFT combines a common set of techniques familiar to all plastic surgeons. Comparing the two methods for clinical effectiveness and complications for equivalency in outcomes may help elucidate and enhance patient decision-making. A retrospective review of a prospectively maintained database between March of 2017 and July of 2018 was performed to compare the LIFTs and FTTs performed by the senior surgeon. Outcomes of interest included postoperative complications, flap success, and follow-up revision and fat-grafting procedures. Sixty-five breasts were reconstructed by FTT; and 31 breasts were reconstructed with LIFT. Demographics were similar (p > 0.05). LIFT had a shorter length of operation time (343 ± 128 minutes versus 49 ± 137 minutes) (p < 0.0001) and a shorter length of stay (1.65 ± 0.85 days versus 3.83 ± 1.65 days) (p < 0.001). FTTs had a shorter time until drain removal (13.3 ± 4.3 days versus 24.0 ± 11.2 days) (p < 0.0001). The number of major (requiring operation) and minor complications were not statistically different (i.e., FTTs, 20.0 percent major and 27.7 percent minor; LIFT, 12.9 percent major and 19.35 percent minor) (p > 0.05). The need for revisions (FTTs, 0.80 ± 0.71; LIFT, 0.87 ± 0.71) and fat grafting (FTTs, 41.54 percent; LIFT, 58.8 percent) was not statistically different (p > 0.05). Both the LIFT and abdominally based FTT have similar outcomes and complication rates. However, LIFT may be preferred in patients who require shorter operation times. The LIFT may be the fully autologous breast reconstruction of choice for nonmicrosurgeons. Therapeutic, III.

[How well are patients informed on the websites of German university breast centres about the possibilities of breast reconstruction?]

In recent decades, the internet has become one of the most important sources of information for patients. How substantial are the possibilities to find out about breast reconstruction on the homepages of university hospitals in Germany? Is there information about plastic surgery with its spectrum of modern reconstructive possibilities? A total of 35 homepages of university breast centres in Germany was analysed for the indication of cooperation with a plastic surgeon or a department for plastic surgery and their links, with information on reconstructive possibilities such as implant reconstruction, autologous soft tissue reconstruction with pedicled and free flaps as well as lipofilling. A plastic surgeon or a cooperating department is mentioned on 49 % of the homepages. Of those homepages, 20 % contain a direct link. 91 % of the homepages describe the possibility of breast reconstruction in general, 80 % of the websites the use of autologous tissue. In 51 % of the cases, a free tissue transfer is mentioned, whereas only 23 % describe the procedures like DIEP flap, TMG, or I-GAP in more detail. Only two centres use detailed illustrations. Six websites (17 %) describe reconstruction by pedicled TRAM flap only. Breast reconstruction with a silicone implant is mentioned on 71 % of the websites. The possibility of lipofilling is discussed in 31 %. About half of the websites of university breast centres do not show any cooperation with a plastic surgeon. There are significant gaps in the information on free tissue transfer for breast reconstruction.

A Nationwide Analysis of Early and Late Readmissions following Free Tissue Transfer for Breast Reconstruction.

Traditionally, surgical quality outcomes are assessed using a 30-day postoperative window. For breast cancer patients undergoing free tissue transfer for breast reconstruction, we sought to describe the distribution of and specific risk factors for early and late readmissions within a 0- to 90-day postoperative period. The Nationwide Readmissions Database was used to conduct a retrospective cohort study. Breast cancer patients undergoing free tissue transfer for breast reconstruction were identified using International Classification of Diseases -9 diagnosis and procedure codes. Ninety-day readmissions related to infection or wound complications were identified. Univariable and multivariable logistic regression models were used to identify patient risk factors for readmissions that occurred early (0-30 days) and late (31-90 days) after their index procedure. In the weighted sample, we identified approximately 7,305 free flap breast reconstructions and a surgical wound-related readmission rate of 4.3% (n = 312): 65.4% of the readmissions occurred early while 34.6% occurred late after surgery. The mean days to readmission was 26, and 75% of all readmissions occurred within the first 36 days after surgery. Variables independently associated with readmissions during the 0- to 90-day postoperative period included: history of chronic obstructive pulmonary disease (p = 0.036), hypertension (p = 0.03), obesity (p ≤ 0.001), and history of smoking (p = 0.004). The variables independently associated with the early readmission period were the same as those identified for the 0- to 90-day postoperative period. The variables independently associated with late readmissions were different: history of depression (p = 0.001) and history of smoking (p = 0.001). The conventional 30-day hospital readmission rate classically used as a quality metric is overlooking a significant portion of admissions after free flap-based breast reconstruction. Different variables were found to be associated with readmission in the early versus late cohorts. Interventions targeting these variables could decrease readmissions and their associated costs.

Body mass index and abdominal wall thickness correlate with perforator caliber in free abdominal tissue transfer for breast reconstruction

IntroductionThe aim of the study was to investigate the relationship of BMI and abdominal wall thickness (AWT) with the diameter of the dominant deep inferior epigastric artery perforator (DIEP) as well as DIEA branching pattern in preoperatively performed computed tomography angiography (CTA). Patients and methodsWe conducted a retrospective study including all patients undergoing DIEP flap breast reconstruction with available CTAs from November 2013 to April 2018 in our department. The caliber-strongest DIEP was detected after passage of the rectus fascia as well as the superficial inferior epigastric artery (SIEA) and correlated with the AWT 5 cm above and below the umbilicus, lateral at the level of the umbilicus and at the level of the anterior superior iliac spine (ASIS), and with BMI. ResultsSeventy-seven patients met the inclusion criteria (age: 47.3 ± 8.9 years). We observed a significant relationship (p < 0.05) between DIEP (mean ∅ = 2.98 mm) and BMI (r = 0.353), the AWT supra- and infraumbilical (r ≥ 0.32), and the AWT lateral at the level of the umbilicus and ASIS (r ≥ 0.25). In addition, there was a highly significant correlation (p < 0.01) between SIEA and BMI (r = 0.389) and between the AWT lateral at the level of ASIS (r ≥ 0.41). ConclusionWe demonstrated a correlation of the diameter of the dominant DIEP with both BMI and AWT. Focusing on the diameter, in patients with a high AWT at the level of the ASIS, the SIEA, if present, may represent an alternative therapeutic option.

Use of Near-infrared Spectroscopy and Implantable Doppler for Postoperative Monitoring of Free Tissue Transfer for Breast Reconstruction: A Systematic Review and Meta-analysis.

Failure to accurately assess the perfusion of free tissue transfer (FTT) in the early postoperative period may contribute to failure, which is a source of major patient morbidity and healthcare costs. This systematic review and meta-analysis aim to evaluate and appraise current evidence for the use of near-infrared spectroscopy (NIRS) and/or implantable Doppler (ID) devices compared with conventional clinical assessment (CCA) for postoperative monitoring of FTT in reconstructive breast surgery. A systematic literature search was performed in accordance with the preferred reporting items for systematic reviews guidelines. Studies in human subjects published within the last decade relevant to the review question were identified. Meta-analysis using random-effects models of FTT failure rate and STARD scoring was then performed on the retrieved publications. Nineteen studies met the inclusions criteria. For NIRS and ID, the mean sensitivity for the detection of FTT failure is 99.36% and 100% respectively, with average specificity of 99.36% and 97.63%, respectively. From studies with sufficient reported data, meta-analysis results demonstrated that both NIRS [OR = 0.09 (0.02-0.36); P < 0.001] and ID [OR = 0.39 (0.27-0.95); P = 0.04] were associated with significant reduction of FTT failure rates compared with CCA. The use of ID and NIRS provided equivalent outcomes in detecting FTT failure and were superior to CCA. The ability to acquire continuous objective physiological data regarding tissue perfusion is a perceived advantage of these techniques. Reduced clinical staff workload and minimized hospital costs are also perceived as positive consequences of their use.

Pyoderma Gangrenosum After Abdominal Free Tissue Transfer for Breast Reconstruction: Case Series and Management Guidelines.

Pyoderma gangrenosum following free tissue transfer for breast reconstruction is rare. This unusual ulcerative condition is frequently misdiagnosed, leading to inappropriate debridement and escalation of the subsequent wound through pathergy. Once diagnosed, treatment with immunosuppressive agents, including corticosteroids, results in an initial rapid response, but prolonged treatment is required. There is a paucity of literature regarding how to approach future surgery. This was a retrospective case review from a single center over a 17-year period. All patients diagnosed with postsurgical pyoderma gangrenosum after free tissue transfer from the abdomen for breast reconstruction were included. Of 456 free tissue transfers from the abdomen for breast reconstruction, 8 women who underwent 13 free flaps were diagnosed with postsurgical pyoderma gangrenosum in 10 flaps. The surgeries performed included transverse rectus abdominis muscle (n = 5), deep inferior epigastric perforator (n = 4) and superficial inferior epigastric artery (n = 4) flaps. Mean age at diagnosis was 52.8 years, and 3 patients had preexisting autoimmune conditions: type 2 diabetes mellitus, dermatomyositis, and Graves disease. The mean time of presentation of wound symptoms was 3.9 days after surgery, and mean time diagnosis was made was 9.4 days. Pyoderma gangrenosum after autologous breast reconstruction is a rare, but serious, complication that is worsened by misdiagnosis and inappropriate debridement. We present a case series of 8 patients and emphasize the importance of early recognition and treatment with immune suppression. We include a treatment algorithm to manage these patients, once the diagnosis is suspected. Future surgery can be considered with a fully informed patient and careful collaboration with dermatology colleagues.

The use of tranexamic acid in microsurgery—is it safe?

An appropriate and adequate blood flow and oxygen delivery is paramount to free flap viability and success. The perioperative use of tranexamic acid (TXA) is associated with less risk for blood loss and blood transfusion in trauma, gynaecology, ear nose and throat (ENT) and orthopaedic surgery. As an antifibrinolytic drug, TXA has generally been avoided in microsurgery. The aim of this study is to evaluate the safety and benefit of using TXA in microsurgery. We performed a retrospective single centre cohort study at the Pyramid Clinic, Zurich, Switzerland, including 98 free tissue transfers for breast reconstruction from 2011 to 2013. According to the estimated blood loss, up to 3 g TXA were administered intravenously in 63 free flaps perioperatively. No thrombosis (0%) of micro-anastomosis and 5 haematomas (10.0%) occurred after administration of TXA. In the control group, 1 thrombosis (3.0%) of a flap-vein and 6 haematomas (18.2%) occurred. Blood loss was significant lower (P<0.001) after administration of TXA. In this study, administration of TXA did not increase thrombosis in free tissue transfer and showed a reduced haematoma rate and significant reduction of blood loss. TXA is supposed to be safe and a reasonable adjunct for patients with anaemia and a higher intraoperative or postoperative blood loss.

Cephalic vein transposition in autologous breast reconstruction salvage: a review of outcomes and implications for patient care

Success in microsurgical autologous breast reconstruction is reliant on establishing an effective circulation. Cephalic vein transposition (CVT) is a technique for augmentation, supercharging or replacement of problematic venous anastomoses for free flap salvage. Little is known about the consequences of using this valuable surgical lifeboat for patients. We investigated our experience of CVTs, focusing on the development of lymphedema in the cephalic vein donor limb. A retrospective review was undertaken of consecutive patients undergoing autologous microsurgical breast reconstruction between 2009 and 2015. Patients requiring CVTs were identified and notes reviewed. Outcome measures included further surgery, flap survival, and complications. Between 2009 and 2015, 1208 autologous free tissue transfers for breast reconstruction were performed at our institution. Twelve patients required CVTs for flap salvage. Eleven notes were available for review. Mean age at reconstruction was 51 (43–74). All patients had previous axillary surgery, with post-mastectomy lymphedema noted in four patients. Reconstructions were seven MS-TRAM and four DIEP flaps. Indications for CVT were venous insufficiency in all but one patient, who had scarred internal mammary vessels. No anastomoses required revision and all flaps survived. No wound healing or scar problems were encountered. Lymphedema worsened in two patients and arose de novo in another two patients. The cephalic vein is an excellent local option for free flap salvage in breast reconstruction. Lymphedema, however, developed or worsened in one third of our patients. All patients undergoing microsurgical breast reconstruction are now counseled about the potential need for CVT and the risk of lymphedema. Level of Evidence: Level IV, therapeutic study.

Computed tomography angiographic study of internal mammary perforators and their use as recipient vessels for free tissue transfer in breast reconstruction.

Context:The internal mammary artery perforator vessels (IMPV) as a recipient in free flap breast reconstruction offer advantages over the more commonly used thoracodorsal vessels and the internal mammary vessels (IMV).Aims:This study was designed to assess the anatomical consistency of the IMPV and the suitability of these vessels for use as recipients in free flap breast reconstruction.Patients and Methods:Data from ten randomly selected female patients who did not have any chest wall or breast pathology but had undergone a computed tomography angiography (CTA) for unrelated diagnostic reasons from April 2013 to October 2013 were analysed. Retrospective data of seven patients who had undergone mastectomy for breast cancer and had been primarily reconstructed with a deep inferior epigastric artery perforator free flap transfer using the IMPV as recipient vessels were studied.Results:The CTA findings showed that the internal mammary perforator was consistently present in all cases bilaterally. In all cases, the dominant perforator arose from the upper four intercostal spaces (ICS) with the majority (55%) arising from the 2nd ICS. The mean distance of the perforators from the sternal border at the level of pectoralis muscle surface on the right side was 1.86 cm (range: 0.9–2.5 cm) with a mode value of 1.9 cm. On the left side, a mean of 1.77 cm (range: 1.5–2.1 cm) and a mode value of 1.7 cm were observed. Mean perforator artery diameters on the right and left sides were 2.2 mm and 2.4 mm, respectively.Conclusions:Though the internal mammary perforators are anatomically consistent, their use as recipients in free tissue transfer for breast reconstruction eventually rests on multiple variables.

Do Prior Abdominal Surgeries Increase Complications in Abdominally Based Breast Reconstructions?

A large proportion of patients presenting for autologous breast reconstruction have a history of prior abdominal surgeries such as obstetric, gynecologic, or general surgical procedures. The impact of prior abdominal wall violation on the ability to perform free tissue transfer from the abdomen needs to be explored and characterized. The purpose of this study was to assess the impact of prior abdominal surgery on perfusion-related complications and donor-site morbidity in free tissue abdominal transfer. All patients who underwent abdominally based free tissue transfer for breast reconstruction from 2005 to 2011 at the Hospital of the University of Pennsylvania were included. In addition to collecting data on standard patient past medical histories, comorbidities, and case characteristics, we also noted specific types of prior abdominal surgeries, number of prior surgeries, and if the rectus sheath was violated. Outcomes assessed included thrombotic complications, flap loss, major surgical complications, minor surgical complications, delayed wound healing, and subsequent hernia formation. Eight hundred twelve patients underwent 1257 free flap breast reconstructions during the study period. Four hundred seventeen (51.4%) women had undergone prior abdominal surgery. The most common prior abdominal surgeries included total abdominal hysterectomy and/or bilateral salpingo-oophorectomy (35.7%), cesarean delivery (33.8%), and appendectomy (12.7%). No significant differences were noted in the number of major intraoperative complications (P = 0.68), total thrombotic events (P = 0.339), or flap losses (P = 0.53). Patients who had undergone prior rectus sheath violation were found to experience a greater amount of delayed healing of the donor site (22.7% vs 16.5%, P = 0.03). Additionally, a higher rate of postoperative hernia formation was noted in patients who had undergone prior hernia repairs (13.6% vs 3.3%, P = 0.04). A significant portion of patients presenting for breast reconstruction have had prior abdominal surgeries. This study demonstrates that these prior procedures represent an acceptable level of risk; although this issue should still be addressed during preoperative patient counseling. In patients with prior hernia repairs, however, additional care should be given to the fascial closure as these patients may be at higher risk for subsequent hernia formation after abdominally based breast reconstruction.

African-American women have equivalent outcomes following autologous free flap breast reconstruction despite greater preoperative risk factors

BackgroundDisparities along racial and ethnic lines exist in breast cancer treatment and reconstruction. This study compares preoperative characteristics among female breast cancer patients who received autologous breast reconstruction to determine if race affects clinical outcomes. MethodsWomen receiving autologous breast reconstruction at a single institution from 2005 to 2011 were identified within a prospectively maintained database. Preoperative risk factors and rates of postoperative morbidity and mortality were assessed with respect to race. ResultsAfrican-American patients had significantly higher rates of preoperative comorbidities than Caucasian patients. Despite the heightened preoperative risk factors, postoperative complications did not significantly differ between racial categories. ConclusionAs the alleviation of healthcare disparities remains a focus of healthcare reform, these findings are beneficial in further educating African-American breast cancer patients and their providers of the safe and viable option of autologous tissue transfer for breast reconstruction.

Serratus branch as recipient vessel for microvascular tissue transfer in breast reconstruction.

Sir: Although the internal mammary vessels remain the recipient vessels of choice in free flap breast reconstruction, the thoracodorsal vessels are still chosen for a variety of reasons. The use of the internal mammary artery as a recipient vessel is justified despite concern for future coronary revascularization.1 The thoracodorsal vessels continue to be used because of surgeon preference and cases of suboptimal internal mammary vessels upon dissection. The potential disadvantages of the thoracodorsal artery and vein as recipient vessels include difficultly in achieving medial fullness in the final breast mound and the inability to use the latissimus flap for future breast reconstruction. We present a case in which the serratus branch is used as recipient vessels for microvascular tissue transfer, with the advantage of preserving the thoracodorsal vessels for future flap reconstruction. The patient is a 44-year-old woman with history of left breast cancer status post mastectomy, who presented for delayed autologous free flap reconstruction. After excision of the previous mastectomy scar, the prepectoral pocket was created. It was noted that the previous mastectomy scar went quite lateral, and therefore, the decision was made to dissect the thoracodorsal vessels. During the dissection, the serratus branch of the thoracodorsal vessels was noted to be quite large and suitable for microvascular anastomosis (Fig. 1). We chose to use the serratus branch as recipient vessels to spare the thoracodorsal vessels. This would allow for future use of her latissimus muscle for breast or general reconstruction. Fig. 1. Dissection of the thoracodorsal vessels. The serratus branch of the thoracodorsal vessels was found large and suitable for microvascular anastomosis. Few studies have described the use of the serratus branch as recipient vessels for microvascular transfer. Arnez et al2 describe a case of a patient who underwent a free transverse rectus abdominis myocutaneous flap reconstruction with the serratus anterior branch as a recipient vessel, thus conserving the remainder of the thoracodorsal vessels in case they were needed in a secondary salvage surgery. In a study describing their experience with 50 free TRAM flap reconstructions, Arnez et al3 describe 1 of 2 reconstructions using the serratus branch, citing the superior back flow of the serratus branch in comparison with the flow of the proximal pedicle. Another group describes their use of the serratus branch as recipient vessels in 4 patients undergoing partial breast reconstruction with mini-superficial inferior epigastric artery and mini-deep inferior epigastric artery perforator flaps to achieve the proper anatomic placement of miniflaps.4 Most cases describe the use of the serratus branch and other distal branches of the thoracodorsal artery as a means to successfully salvage a deep inferior epigastric artery perforator flap through retrograde flow anastomosis.5 In conclusion, the serratus branch of the thoracodorsal vessels provides a viable recipient site for microvascular tissue transfer with the advantages of sparing the thoracodorsal vessels for future latissimus flap reconstruction.

Optimizing the Fascial Closure

Donor-site morbidity continues to be a significant complication in patients undergoing abdominally based breast reconstruction. The purposes of our study were to critically examine abdominal donor-site morbidity and to present our algorithm for optimizing donor site closure to reduce these complications. We performed a retrospective cohort study examining all patients undergoing abdominally based free tissue transfer for breast reconstruction from 2005 to 2011 at our institution. Data were analyzed for overall donor site morbidity, as defined by hernia/bulge or reoperation for debridement and/or mesh removal and for hernia/bulge alone. A total of 812 patients underwent 1261 free tissue transfers. Fifty-three patients (6.5%) experienced donor-site morbidity, including 27 hernias/bulges (3.3%). No significant difference in overall abdominal morbidity was found between unilateral and bilateral reconstructions (P = 0.39) or the use of muscle in the flap (P = 0.11 unilateral msfTRAM, P = 0.76 bilateral). Prior lower abdominal surgery was associated with higher rates of donor-site morbidity (P = 0.04); hypertension (P = 0.012) and multiple medical comorbidities (P < 0.001) were also significantly more common in these patients. Obesity was the only patient characteristic associated with higher rates of hernia/bulge (P = 0.04). Delayed abdominal would healing was associated with hernia/bulge (P < 0.001); these patients were significantly more likely to develop this complication (odds ratio = 6.3, P < 0.001). Particular attention must be provided to donor-site closure in obese patients and those with hypertension and multiple medical comorbidities. Low rates of abdominal wall morbidity result from meticulous fascial reconstruction and reinforcement and careful attention to tension-free soft tissue closure.

Accurately costing unilateral delayed DIEP flap breast reconstruction

Free tissue transfer for breast reconstruction is widely practiced in the UK and its availability forms part of the NICE guidelines in treating breast cancer. Free flap reconstruction scores highly on patient reported outcome measures for both immediate and delayed procedures. However there are significant resource implications and a concern that the financial burden is not adequately met by the fixed price tariff system (Payment by Results). This study aims to compare the cost of treatment with both local financial estimates and reimbursement. We conducted a prospective costing analysis for 10 consecutive delayed unilateral DIEP breast reconstructions from August 2011 by a single surgeon in Frenchay Hospital, Bristol. Comparison was made to both the hospital's costing estimates and the Health Resource Group (HRG) tariffs received for 27 similar cases performed by the same surgeon in the 2010-11 financial year. The mean treatment cost for performing a delayed unilateral DIEP procedure was £7628 (±£754 Standard Deviation). This compared to an estimate from the financial department of £8072±(£1683 SD). These values were not significantly different (p=0.27). The HRG tariff was £8792 (±£423 SD). There was an average net income of £720 per case. Personnel in theatre represented the largest cost area at an average of 73% of total cost. This study highlights that the costs of this procedure have been estimated accurately by the financial department and that the current HRG code provides adequate reimbursement. The new HRG code for 2012-13, HRG JA14z, provides significantly less reimbursement at £7012 and measures need to be taken to address this. This study has identified that personnel costs are the greatest contributor to overall cost and allowed us to recognise and implement changes to improve efficiency.

Comprehensive Outcome and Cost Analysis of Free Tissue Transfer for Breast Reconstruction

Free tissue transfer is standard for postoncologic reconstruction, yet it entails a lengthy operation and significant recovery. The authors present their longitudinal experience of free tissue breast reconstructions with an emphasis on predictors of major surgical and medical complications. The authors reviewed their prospectively maintained free flap database and identified oncologic breast reconstruction patients from 2005 to 2011. Factors associated with surgical and medical complications were identified using univariate analyses and logistic regression to determine predictors of complications. Complications included major immediate surgical complications [n = 34 (4.0 percent)], major delayed surgical complications [n = 54 (6.4 percent)], minor surgical complications [n = 404 (47.6 percent)], and medical complications [n = 50 (5.9 percent)]. Obesity (p = 0.034), smoking (p = 0.06), flap type (p = 0.005), and recipient vessels (p < 0.001) were associated with immediate complications. Similarly, delayed surgical complications were associated with obesity (p < 0.001), chronic obstructive pulmonary disease (p < 0.001), hypertension (p < 0.001), and prior radiation therapy (p = 0.06). Regression analysis demonstrated that flap choice (p = 0.024) was independently associated with major immediate complications, and patient comorbidities such as chronic obstructive pulmonary disease (p = 0.001) and obesity (p < 0.0001) were associated with delayed complications. Patients who developed an immediate surgical complication experienced longer hospital stays (p < 0.0001), higher operating costs (p < 0.001), and greater hospital costs (p < 0.001). Early major complications are related to flap selection, whereas late major complications are associated with patient comorbidities. Overall, major surgical and medical complications are associated with increased hospital length of stay and greater cost in autologous breast reconstruction. Risk, III.
