Understanding the Appropriate and Beneficial Use of Before and After Photos in Breast Surgery: A North American Survey.

Introduction: Before and after photographs (BAPs) in breast surgery have been identified as important components of the informed consent process. Currently, there is limited consensus on the contents and presentation of BAPs. This study collected the opinions of prior and prospective patients on this topic. Methods: A survey, based on criteria identified by our previous nominal group technique (NGT) study, was designed to obtain patient perspectives on BAPs in breast surgery. Amazon Mechanical Turk, a validated crowd-sourcing tool, was used to identify and survey a group of 72 participants who indicated that they had undergone or were planning to undergo breast surgery. Likert items were analyzed using either chi-squared or Fisher's exact test. Results: Most respondents were cis-gendered-women (89%), Caucasian (83%), and between 31 and 41 years old (38%). Respondents agreed that BAPs are important to the consent process, for enabling patient-centered care, and should be presented in standardized sets. BAPs should be more accessible through different platforms, display multiple time points to show the healing process, and have multiple views including close-ups of scars. Photos should be unaltered except for de-identification, and have more diversity with regard to patient gender, age, skin color, and body mass index. These results align with results from our NGT study. Conclusion: Through this study we have identified many criteria that BAPs should meet according to prior and prospective breast surgery patients. Surgeons should think critically about how they present BAPs during the consent process to ensure effective patient-centered care.

Introduction : En chirurgie mammaire, les photos avant-après (PAP) font partie des aspects importants du processus de consentement éclairé. À l'heure actuelle, le consensus sur le contenu et la présentation des PAP est limité. La présente étude visait à recueillir l'avis de patientes passées et prospectives sur le sujet. Méthodologie : Les chercheurs ont préparé un sondage reposant sur les critères qu'ils avaient établis lors de leur étude antérieure sur la technique du groupe nominal (TGN) pour obtenir les points de vue des patients sur les PAP en chirurgie mammaire. Ils ont utilisé l'outil de production participative validé MechanicalTurk d'Amazon pour repérer et sonder un groupe de 72 participants qui ont indiqué avoir subi ou planifié de subir une chirurgie mammaire. Ils ont analysé les énoncés de l'échelle de Likert au moyen du test du chi carré ou de la méthode exacte de Fisher. Résultats : La plupart des répondants étaient des femme cisgenres (89%), blanches (83%), âgées de 31 à 41 ans (38%). Ces répondants ont convenu que les PAP constituent un aspect important du processus de consentement, qu'elles favorisent des soins axés sur les patients et qu'elles doivent être présentées sous forme d'ensembles standardisés. Les PAP devraient être plus accessibles sur diverses plateformes, présenter divers moments du processus de guérison et de multiples points de vue, y compris des gros plans des cicatrices. Les photos devraient être inaltérées, à part pour la désidentification, et refléter une plus grande diversité de genres, d'âges, de couleurs de peau et d'indices de masse corporelle. Ces résultats concordent avec ceux de l'étude antérieure par la TGN. Conclusion : Grâce à la présente étude, les chercheurs ont relevé de nombreux critères que doivent respecter les PAP selon les patients passés et prospectifs en chirurgie mammaire. Les chirurgiens devraient recourir à la réflexion critique quant à la manière de présenter les PAP pendant le processus de consentement pour s'assurer de prodiguer des soins efficaces axés sur les patients.

The Versatility of Lateral Chest Wall Perforator Flaps in Immediate and Delayed Breast Reconstruction: Retrospective Study of Clinical Experience with 26 Patients.

Rationale: Lateral chest flaps represent versatile reconstructive options, especially valuable in times of global healthcare resource restriction. In this series, we present our experience with the use of lateral chest wall flaps in both immediate and delayed reconstruction from both breast conserving and mastectomy surgery. Methods: A retrospective cohort study of patients who had undergone a lateral chest wall flap for immediate or delayed breast reconstruction of a lumpectomy or mastectomy defect was performed. Data collected consisted of patient demographics, procedure type, tumor/oncological characteristics, as well as postoperative complications. Findings: Between September 2015 and April 2021, 26 patients underwent breast reconstruction using a lateral chest wall flap. Fifteen patients (58%) underwent immediate reconstruction (9 lumpectomy; 6 mastectomy) and 11 (42%) underwent delayed breast reconstruction. All flaps survived, though 1 patient required partial flap debridement following venous compromise hours after surgery. There were no incidences of hematoma, seroma, infection, or wound healing delay at either the donor site or breast. There was one positive margin which occurred in a mastectomy patient. Significance: This study describes the use of lateral chest wall flaps in a wide variety of reconstructive breast surgery scenarios. This technique can be safely performed in an outpatient setting and does not require microvascular techniques. Review of our outcomes and complications demonstrate that this is a safe and effective option. Our experience is that this is an easy to learn, versatile flap that could be a valuable addition to the surgeon's arsenal in breast reconstruction.

Justification: Les lambeaux thoraciques latéraux constituent une option de reconstruction polyvalente, particulièrement utile par des temps de restriction globale des ressources en soins de santé. Dans cette série, nous présentons notre expérience de l'utilisation du volet latéral de paroi thoracique aussi bien en cas de reconstruction immédiate que différée pour les chirurgies de conservation du sein et pour les mastectomies. Méthodes: Une étude de cohorte rétrospective de patientes ayant subi un lambeau latéral de la paroi thoracique pour reconstruction immédiate ou différée du sein pour lumpectomie ou mastectomie a été réalisée. Les données collectées ont inclus les caractéristiques démographiques des patientes, le type de procédure, les caractéristiques de la tumeur/oncologiques ainsi que les complications postopératoires. Résultats: Entre septembre 2015 et avril 2021, vingt-six patientes ont subi une reconstruction du sein avec lambeau latéral de la paroi thoracique. Quinze patientes (58%) ont eu une reconstruction immédiate (9 lumpectomies, 6 mastectomies) et onze (42%) ont eu une reconstruction différée du sein. Tous les lambeaux ont survécu bien qu'une patiente ait nécessité un débridement partiel du lambeau après un trouble veineux, quelques heures après l'intervention chirurgicale. Il n'y a pas eu de survenue d'hématome, de sérome, d'infection ou de retard de cicatrisation au niveau du site donneur ou du sein. Des marges positives sont survenues chez une patiente mastectomisée. Signification: Cette étude décrit l'utilisation de lambeaux latéraux de la paroi thoracique dans une grande variété de scénarios de chirurgie mammaire reconstructrice. Cette technique peut être employée de manière sécuritaire dans un cadre ambulatoire et ne nécessite pas de recours à des techniques microvasculaires. L'analyse de nos résultats et des complications démontre qu'il s'agit d'une option sécuritaire et efficace. Selon notre expérience, cette technique est facile à apprendre; le lambeau polyvalent pourrait être un supplément intéressant dans l'arsenal du chirurgien pour la reconstruction mammaire.

Canadian Expert Opinion on Breast Reconstruction Access: Strategies to Optimize Care during COVID-19.

BACKGROUND: Breast reconstructive services are medically necessary, time-sensitive procedures with meaningful health-related quality of life benefits for breast cancer survivors. The COVID-19 global pandemic has resulted in unprecedented restrictions in surgical access, including access to breast reconstructive services. A national approach is needed to guide the strategic use of resources during times of fluctuating restrictions on surgical access due to COVID-19 demands on hospital capacity. METHODS: A national team of experts were convened for critical review of healthcare needs and development of recommendations and strategies for patients seeking breast reconstruction during the pandemic. Following critical review of literature, expert discussion by teleconference meetings, and evidenced-based consensus, best practice recommendations were developed to guide national provision of breast reconstructive services. RESULTS: Recommendations include strategic use of multidisciplinary teams for patient selection and triage with centralized coordinated use of alternate treatment plans during times of resource restrictions. With shared decision-making, patient-centered shifting and consolidation of resources facilitate efficient allocation. Targeted application of perioperative management strategies and surgical treatment plans maximize the provision of breast reconstructive services. CONCLUSIONS: A unified national approach to strategically reorganize healthcare delivery is feasible to uphold standards of patient-centered care for patients interested in breast reconstruction.

Comparing post-surgical outcomes of pre-pectoral versus dual-plane direct-to-implant breast reconstruction without increasing the use of acellular dermal matrix.

BACKGROUND: Direct-to-implant (DTI) reconstruction when performed using the dual-plane technique can be associated with increased postoperative pain, longer recovery, functional impairment, and animation deformity. These issues can be avoided by using the pre-pectoral technique that traditionally uses larger pieces of the acellular dermal matrix (ADM) and results in increased costs. It is unclear how these two methods compare when the technique is modified to avoid the use of additional ADM. METHODS: A retrospective chart review was conducted of all patients who underwent DTI breast reconstruction using a dual-plane or pre-pectoral technique between January 2014 and December 2019. Pre-pectoral breast reconstruction was performed using a partial anterior coverage technique, and therefore no additional ADM was used per case as compared to the dual-plane technique. Rates of post-surgical complications were compared between the two groups. RESULTS: Of 77 patients, 48 (86 breasts) underwent dual-plane reconstruction, whereas 29 (48 breasts) underwent pre-pectoral reconstruction. Mean follow-up time for the dual-plane and pre-pectoral groups was 23.3 and 8.7 months, respectively (p<0.001). There were no significant differences in the rates of any of the short-term post-surgical outcomes between the two groups: seroma (14% vs 6.3%, p = 0.175); hematoma (2.3% vs 4.2%, p = 0.617); skin/nipple necrosis (7% vs 10.4%, p = 0.522); wound skin infection (2.3% vs 2.1%, p = 1.0); wound dehiscence (4.7% vs 2.1, p = 0.654); and implant loss (1.2% vs 8.3%, p = 0.055). CONCLUSIONS: Pre-pectoral reconstruction using a partial anterior coverage technique appears to be a safe alternative to dual-plane reconstruction when considering short-term post-surgical complications.

Predictive value of 3D imaging to guide implant selection in immediate breast reconstruction.

BACKGROUND: Pre-operative estimation of breast mound volume for immediate breast reconstruction is necessary for operative planning, especially in direct-to-implant reconstruction. Our purpose was to investigate the relationship between pre-operative predictions of breast mound weight from 3D imaging and actual mastectomy weight and implant size. METHODS: A retrospective chart review of all patients who had previously undergone nipple-sparing mastectomy (NSM) by a single surgeon was performed. Pre-operative 3D images were reviewed and calculations of breast mound weight were performed by three independent reviewers. Intra-operative mastectomy weight and final implant weight were collected from patient charts. A regression analysis between calculated and actual values was performed. RESULTS: There were 59 reconstructed breasts included. Pre-operative 3D imaging-guided breast weight calculations were similar across reviewers (R=0.96). Pre-operative calculations of breast weight were 49.4g (SD=134.0) smaller than actual mastectomy specimens. Mastectomy specimens were 41.0g (SD=130.2) smaller than final implant sizes. Thereby, the relationship was as follows: Pre-operative calculated breast weight < actual Mastectomy weight < implant weight. Mastectomy weight and final implant size had linear relationships with pre-operative calculations of breast weight. Formulas for predicting mastectomy weight [mastectomy weight = 63.2 + 0.95 (pre-operative calculated weight)] and implant size [Implant weight = 209.7+ 0.56 (pre-operative calculated weight)] from pre-operative calculations of breast weight were generated. CONCLUSIONS: Three-dimensional scanning technologies may be a useful tool to predict implant sizes for direct-to-implant breast reconstruction. Final implant size was heavier than intra-operative mastectomy weight and pre-operative calculated breast mound weight.

Can We Reach a Consensus on the Appropriate Use of Before and After Photos in Breast Surgery?

Breast surgery is an area of practice where patients value before and after photographs (BAPs). Consensus is needed to develop guidelines to address the deficit in the literature regarding appropriate use of BAPs, as these may ultimately play a significant role in the breast surgery consent process. METHODS: Expert breast reconstructive surgeons participated in a modified nominal group technique (NGT) to establish expert consensus on categories and criteria to be used when evaluating appropriate use of BAPs as part of informed consent. Endorsement rate of 75% and coefficients of variance within and between rounds were conducted to determine validity of each criteria item's rank order. RESULTS: Eight experts participated in the NGT in-person meeting and subsequent online survey. five of seven categories were endorsed for discussion: purpose, image type, anatomy, results, and photographic integrity. Overall consensus was obtained for six of 11 criteria. Criteria items found to have consensus were: patients considering surgery being the intended photograph audience (100% endorsement, CV1 - CV2 = 0.01), use of photographic images (75% endorsement, CV1 - CV2 = 0.04), defining the standard clinical photograph by having patients in the same body position (100% endorsement, CV1 - CV2 = 0.14), anonymizing images by removing all digital tags (88% endorsement, CV1 - CV2 = 0.03) and patient identifiers (75% endorsement, CV1 - CV2 = 0.00), not limiting the number of photograph sets needed for sufficient representation (100% endorsement, CV1 - CV2 = 0.07), and representing average outcomes (100%, CV1 - CV2 = 0.06). CONCLUSIONS: Early use of this validated and effective technique helps identify potential consensus categories and criteria that surgeons recommend for the use of BAPs in the informed consent process. Further study is required.

Breast reconstruction: Updated overview for primary care physicians.

OBJECTIVE: To offer primary care providers a comprehensive summary of breast reconstruction options and complications. QUALITY OF EVIDENCE: A literature search was conducted in PubMed with no time restriction using the search terms breast reconstruction, summary, review, complications, and options. Levels of evidence range from I to III. MAIN MESSAGE: As breast cancer survival rates increase, the focus of breast cancer management must shift to include the restoration of a patient's quality of life after cancer. Breast reconstruction plays a crucial role in the restoration of normality for these women. Women who undergo mastectomy often suffer from challenges related to body image, self-esteem, and a decrease in quality of life scores. Cancer Care Ontario's Breast Cancer Treatment Pathway Map mandates that all women diagnosed with breast cancer who might require mastectomy be referred to a plastic surgeon to discuss reconstructive options before surgery. CONCLUSION: The knowledge and guidance of primary care providers is critical to effectively guiding and supporting patients who might undergo breast reconstruction in their decision-making processes. A thorough understanding of patient selection factors, modern options for breast reconstruction, and expected outcomes is essential.

Reconstruction mammaire: Aperçu actualisé à l'intention des médecins de soins primaires.

OBJECTIF: Présenter aux prestataires de soins primaires un résumé complet des options en matière de reconstruction mammaire et de leurs complications. SOURCES DE L'INFORMATION: Une recherche documentaire a été effectuée dans PubMed, sans restrictions relatives à la date de publication, à l'aide des expressions de recherche en anglais breast reconstruction, summary, review, complications et options. Les niveaux des données probantes varient de I à III. MESSAGE PRINCIPAL: Étant donné la hausse des taux de survie au cancer du sein, la prise en charge doit changer de cap pour inclure aussi la restauration de la qualité de vie de la patiente après le cancer. La reconstruction mammaire joue un rôle majeur pour un retour à la normale chez ces femmes. Les femmes qui subissent une mastectomie éprouvent souvent des difficultés quant à leur image corporelle et à leur estime de soi, et elles évaluent leur qualité de vie à la baisse. La carte des voies pathologiques d'Action Cancer Ontario préconise que toutes les femmes ayant reçu un diagnostic de cancer du sein qui pourraient avoir besoin d'une mastectomie soient envoyées en consultation en chirurgie plastique pour discuter des options de reconstruction avant l'opération. CONCLUSION: Les connaissances et les conseils des médecins de soins primaires sont essentiels pour bien orienter et appuyer les patientes dans leur processus décisionnel quant à la reconstruction mammaire. Il est nécessaire de bien comprendre les facteurs de sélection des patientes, les options contemporaines de reconstruction mammaire et les résultats attendus.

Patient-Reported Outcomes following Breast Conservation Therapy and Barriers to Referral for Partial Breast Reconstruction.

BACKGROUND: The purpose of this study was to evaluate the self-reported aesthetic outcome of breast conservation therapy in a generalized sample of patients, and to describe potential barriers to referral for partial breast reconstruction. METHODS: Consecutive breast conservation therapy patients completing radiotherapy over a 1-year period at a regional cancer center were identified. Eligible patients were contacted by means of mail/e-mail and invited to participate. Participants completed the BREAST-Q breast conservation therapy module along with a questionnaire examining feelings about breast reconstruction. Multiple regression analysis was performed using the satisfaction with breasts scale as the dependent variable. RESULTS: Surveys were completed by 185 of 592 eligible participants (response rate, 31.3 percent; mean age, 61 years) an average of 38 months after lumpectomy. The mean score for the BREAST-Q satisfaction with breasts scale was 59 of 100. Younger age (p = 0.038), lumpectomy reexcision (p = 0.018), and lumpectomy at a nonacademic center (p = 0.026) were significantly associated with lower satisfaction. Bra size, months from lumpectomy, and tumor quadrant/size were not significantly associated with satisfaction (p > 0.05). The most common statements regarding reconstruction were "I don't feel the need for it" (60.0 percent), "I don't like the thought of having breast implants" (22.7 percent), and "I don't want any more surgeon/doctor visits" (22.2 percent). Before lumpectomy, only 1.6 percent had a consultation for reconstruction, and only 22.7 percent were aware of this option. If offered, 33.1 percent of patients would have attended this consultation. CONCLUSION: There is an unmet demand for partial breast reconstruction, with an opportunity to advocate and increase awareness on behalf of patients undergoing breast conservation therapy.

Current Practices and Barriers to the Integration of Oncoplastic Breast Surgery: A Canadian Perspective.

BACKGROUND: Despite the safety and popularity of oncoplastic surgery, there is limited data examining utilization and barriers associated with its incorporation into practice. This study examines the use of oncoplastic techniques in breast conserving surgery and determines the barriers associated with their implementation. METHODS: A 13-item survey was mailed to all registered general surgeons in Ontario, Canada. The survey assessed surgeon demographics, utilization of specific oncoplastic techniques, and perceived barriers. RESULTS: A total of 234 survey responses were received, representing a response rate of 32.2 % (234 of 725). Of the respondents, 166 surgeons (70.9 %) reported a practice volume of at least 25 % breast surgery. Comparison was made between general surgeons performing oncoplastic breast surgery (N = 79) and those who did not use these techniques (N = 87). Surgeon gender, years in practice, fellowship training, and access to plastic surgery were similar across groups. Both groups rated the importance of breast cosmesis similarly. General surgeons with a practice volume involving >50 % breast surgery were more likely to use oncoplastic techniques (OR 8.82, p < .001) and involve plastic surgeons in breast conserving surgery (OR 2.21, p = .02). For surgeons not performing oncoplastic surgery, a lack of training and access to plastic surgeons were identified as significant barriers. For those using oncoplastic techniques, the absence of specific billing codes was identified as a limiting factor. CONCLUSIONS: Lack of training, access to plastic surgeons, and absence of appropriate reimbursement for these cases are significant barriers to the adoption of oncoplastic techniques.

Secondary Breast Augmentation.

LEARNING OBJECTIVES: After studying this article, the participant should be able to: 1. Assess common clinical problems in the secondary breast augmentation patient. 2. Describe a treatment plan to correct the most common complications of breast augmentation. 3. Provide surgical and nonsurgical options for managing complications of breast augmentation. 4. Decrease the incidence of future complications through accurate assessment, preoperative planning, and precise surgical technique. SUMMARY: Breast augmentation has been increasing steadily in popularity over the past three decades. Many of these patients present with secondary problems or complications following their primary breast augmentation. Two of the most common complications are capsular contracture and implant malposition. Familiarity and comfort with the assessment and management of these complications is necessary for all plastic surgeons. An up-to-date understanding of current devices and techniques may decrease the need to manage future complications from the current cohort of breast augmentation patients.

Conservative mastectomies and immediate reconstruction with the use of ADMs.

BACKGROUND: In recent years, a novel approach to immediate breast reconstruction has been introduced with the advent of acellular dermal matrix (ADM). In the setting of conservative mastectomies where the native skin envelope is preserved, placement of ADM at the lower pole in continuity with the pectoralis major muscle (PMM) provides additional support, allowing direct-to-implant breast reconstruction. The following manuscript presents the senior author's experience with ADM-assisted reconstruction and provides a detailed description of surgical technique along with a comprehensive discussion of patient selection and potential complications. METHODS: A retrospective chart review of patients undergoing direct-to-implant breast reconstruction following skin sparing or nipple sparing mastectomy with the use of ADM (AlloDerm; LifeCell Corp., Branchburg, USA) was conducted at Women's College Hospital in Toronto over a 5-year period [2008-2013]. Demographic data, previous radiation therapy and post-operative complications were recorded. RESULTS: A total of 72 patients representing 119 breasts were identified. Average follow-up was 16 months (range, 3-51 months). Twenty-seven complications were recorded for a complication rate of 22.7% (27/119). Complications included six cases of capsular contracture (Baker III/IV), five cases of red skin syndrome, four cases of rippling, three cases of dehiscence and two cases of seroma. Overall, direct-to-implant reconstruction was successfully completed in 97.5% of breasts (116/119). One case of infection was treated with explantation and conversion to autogenous reconstruction. Two breasts with tissue necrosis or dehiscence had the implants removed and replaced with tissue expanders. Overall reoperation rate was 9.7% (7/72 patients). CONCLUSIONS: ADM assisted direct-to-implant breast reconstruction has been shown to be a safe option for women who are candidates for skin sparing or nipple sparing mastectomies. Judicious patient selection, effective collaboration between the oncologic and reconstructive surgeon, careful evaluation of post-mastectomy skin flaps and precise surgical technique are paramount to the success of this technique.

Surgical Strategies in the Correction of the Tuberous Breast.

Management of the tuberous breast represents one of the greatest surgical challenges in aesthetic breast surgery, requiring careful assessment and a methodical approach to obtain an acceptable result. The surgeon must be familiar with multiple techniques that can be performed individually or may be combined to address various aspects of the tuberous deformity. This article describes the etiology, anatomic features, identification, and classification of the tuberous breast, focusing on surgical management and potential pitfalls. Through case study, expected outcomes in the management of this complex problem are described.

Correction of small volume breast asymmetry using deep parenchymal resection and identical silicone implants: an early experience.

BACKGROUND: Virtually all patients presenting for augmentation mammaplasty will exhibit some degree of asymmetry. The use of asymmetric implants to address small- volume breast asymmetry introduces uncontrolled variables into the longevity of postoperative results. OBJECTIVES: We described a novel method of addressing small-volume asymmetry using deep parenchymal resection (DPR) to achieve symmetry prior to insertion of identical implants. We also compared our results with this technique to a cohort of standard augmentation mammaplasty patients. METHODS: All patients underwent 3-dimensional (3D) imaging during consultation. In patients with small-volume breast asymmetry, a uniform disk of deep parenchymal tissue was resected from the base of the larger breast cone through an inframammary incision. A standard submuscular augmentation was then completed. Five patients (DPR group) with appreciable small-volume asymmetry underwent DPR in the larger breast prior to insertion of identical implants. Fifty-six consecutive patients with no appreciable volume asymmetry (standard group) underwent standard submuscular breast augmentation. RESULTS: Using 3D imaging preoperatively, DPR-group patients had an estimated breast volume asymmetry of 86 ± 58 g and had 55 ± 27 g excised from the larger breast intraoperatively, allowing for insertion of identical implants in each patient. Complications in the standard group included 1 case of rippling and 2 cases of malposition. One case of malposition was noted in the DPR group. No other complications were recorded in either group over 6 months. CONCLUSIONS: Our novel method of addressing small-volume breast asymmetry allows for the use of identical implants and presents no increase in early complications.

Understanding the factors that influence breast reconstruction decision making in Australian women.

BACKGROUND: Breast reconstruction is safe and improves quality of life. Despite this, many women do not undergo breast reconstruction and the reasons for this are poorly understood. This study aims to identify the factors that influence a woman's decision whether or not to have breast reconstruction and to better understand their attitudes toward reconstruction. METHODOLOGY: An online survey was distributed to breast cancer patients from Breast Cancer Network Australia. Results were tabulated, described qualitatively and analyzed for significance using a multiple logistic regression model. RESULTS: 501 mastectomy patients completed surveys, of which 62% had undergone breast reconstruction. Factors that positively influenced likelihood of reconstruction included lower age, bilateral mastectomy, access to private hospitals, decreased home/work responsibilities, increased level of home support and early discussion of reconstructive options. Most common reasons for avoiding reconstruction included "I don't feel the need" and "I don't want more surgery". The most commonly sited sources of reconstruction information came from the breast surgeon followed by the plastic surgeon then the breast cancer nurse and the most influential of these was the plastic surgeon. CONCLUSIONS: A model using factors easily obtained on clinical history can be used to understand likelihood of reconstruction. This knowledge may help identify barriers to reconstruction, ultimately improving the clinicians' ability to appropriately educate mastectomy patients and ensure effective decision making around breast reconstruction.

Outcomes in primary breast augmentation: a single surgeon's review of 1539 consecutive cases.

BACKGROUND: The use of implants in aesthetic breast surgery may lead to complications resulting in the need for reoperation. This study examines outcomes following breast augmentation in a single surgeon's practice and investigates the effect of implant selection and surgical technique on complications and reoperations. METHODS: A retrospective review of a single surgeon's prospectively maintained database over 15 years was performed. All primary bilateral breast augmentation patients were included. Implant characteristics-including implant type, fill, shape, surface, and projection; incision type; and pocket location-were collected. Complications and reasons for reoperation were analyzed using survival analysis. RESULTS: One thousand five hundred thirty-nine patients with 3078 implants were included. Implant types included 596 shaped textured gel, 515 round smooth saline, 192 round textured gel, and 236 round smooth gel implants. Follow-up ranged from 0 to 155 months (average, 18 months). Total complication and reoperation rates were 6.8 and 7.7 percent, respectively. Inframammary incisions and the use of shaped textured gel implants were associated with lower rates of complications. The use of a dual-plane II or III pocket, and implant volumes over 400 cc, were associated with higher rates of complications. Full-projection round implants had rates of complications and reoperations equivalent to those of moderate-projection devices. Both textured shaped gel implants and a subpectoral pocket location were associated with the lowest rates of capsular contracture. CONCLUSION: This large series of breast implant patients demonstrates that both implant- and technique-related factors may influence complications and reoperations in breast implant surgery. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

Venous thromboembolism in abdominoplasty: a comprehensive approach to lower procedural risk.

BACKGROUND: Venous thromboembolism (VTE) is a serious and potentially life-threatening surgical complication. However, there is little consensus regarding appropriate VTE prophylaxis for plastic surgery patients. Risk factors as they apply to plastic surgery patients are unclear, and recent recommendations for chemoprophylaxis in these patients may expose them to other additional risks. OBJECTIVES: The authors examine perioperative and intraoperative measures, specifically those that have enabled a large number of patients to undergo outpatient abdominoplasty safely, with a reduced risk of VTE. METHODS: A retrospective review was performed of 404 consecutive abdominoplasty patients who were treated at a single outpatient surgery center between 2000 and 2010. Graded compression stockings and intermittent pneumatic compression devices were placed on all patients, and perioperative and intraoperative warming was strictly applied. Progressive tension suturing technique was performed in all cases and drains were eliminated. All patients received pain pumps, ambulated within one hour of surgery, and were discharged home the same day. Patient VTE risk factors were scored with the Caprini/Davison risk assessment model (RAM). Perioperative and intraoperative measures were taken to reduce factors that may increase VTE risk in abdominoplasty. Complications were recorded, including VTE events, seromas, hematomas, and infections. RESULTS: In this series, 247 abdominoplasty procedures were performed alone and 157 were combined with additional procedures. Under the RAM, 297 patients were considered "high risk" and 17 "highest risk." Abdominoplasty operative time was 100 ± 29 minutes. Only one case of deep vein thrombosis (DVT) occurred, in the calf. CONCLUSIONS: A comprehensive approach to perioperative and intraoperative patient care has allowed outpatient abdominoplasty to be safely performed without VTE chemoprophylaxis in patients with fewer than six risk factors.

Efficiency of oxygen administration: sequential gas delivery versus "flow into a cone" methods.

OBJECTIVE: Fio2 values of a new oxygen mask that exploits efficiencies afforded by sequential gas delivery (SGD) were compared to those of a nonrebreathing mask (NRM) and a Venturi oxygen mask. DESIGN: Prospective, single-blinded, randomized study. SETTING: Laboratory study. SUBJECTS: Eight healthy male volunteers. INTERVENTIONS: Volunteers breathed through each of the masks at various minute ventilations (VE). Oxygen flows were 2, 4, and 8 L/min to the SGD mask but only 8 L/min to the other masks. MEASUREMENTS AND MAIN RESULTS: Net FIO2 was calculated from end-tidal fractional concentrations of oxygen and CO2 with the alveolar gas equation. Only the SGD mask at an oxygen flow of 8 L/min consistently provided both FIO2>0.95 (at resting VE) and higher FIO2 than the other masks at all VE. The SGD mask delivered FIO2 comparable to other masks at only a fraction of the oxygen flow and was characterized by a consistent relation between FIO2 and oxygen flow for a given VE. CONCLUSION: We conclude that SGD can be exploited to provide FIO2>0.95 with oxygen flows as low as 8 L/min, as well as accurate and efficient dosing of oxygen even in the presence of hyperpnea.

Preoperative and postoperative mapping of cerebrovascular reactivity in moyamoya disease by using blood oxygen level-dependent magnetic resonance imaging.

OBJECT: The ability to map cerebrovascular reactivity (CVR) at the tissue level in patients with moyamoya disease could have considerable impact on patient management, especially in guiding surgical intervention and assessing the effectiveness of surgical revascularization. This paper introduces a new noninvasive magnetic resonance (MR) imaging-based method to map CVR. Preoperative and postoperative results are reported in three cases to demonstrate the efficacy of this technique in assessing vascular reserve at the microvascular level. METHODS: Three patients with angiographically confirmed moyamoya disease were evaluated before and after surgical revascularization. Measurements of CVR were obtained by rapidly manipulating end-tidal PCO2 between hypercapnic and hypocapnic states during MR imaging. The CVR maps were then calculated by comparing the percentage of changes in MR signal with changes in end-tidal PCO2. Presurgical CVR maps showed distinct regions of positive and negative reactivity that correlated precisely with the vascular territories supplied by severely narrowed vessels. Postsurgical reactivity maps demonstrated improvement in the two patients with positive clinical outcome and no change in the patient in whom a failed superficial temporal artery-middle cerebral artery bypass was performed. CONCLUSIONS: Magnetic imaging-based CVR mapping during rapid manipulation of end-tidal PCO2 is an exciting new method for determining the location and extent of abnormal vascular reactivity secondary to proximal large-vessel stenoses in moyamoya disease. Although the study group is small, there seems to be considerable potential for guiding preoperative decisions and monitoring efficacy of surgical revascularization.

Efficient breathing circuit for use at altitude.

We describe a case report of a subject suffering high-altitude cerebral and pulmonary edema successfully treated with low flow rates of supplemental oxygen administered with a breathing system designed to conserve oxygen supplies at high altitude.
