Evolving Methods and Application of a 3D Printed Model in the Current Deep Inferior Epigastric Perforator Flap Elevation.

The choice of the deep inferior epigastric perforator (DIEP) flap for breast reconstruction has increased. Three-dimensional (3D) models of DIEP flaps have been introduced with advances in 3D technology to assist the tedious intramuscular dissection of the pedicle. This study presents the process of creating an ideal 3D model for a DIEP flap. Collaboration among various professionals, including surgeons, radiologists, and 3D-printing model makers, is essential for manufacturing suitable 3D-printing DIEP models. Our team facilitated the collaboration process by sharing the virtual 3D model via a uniform resource locator (URL) using an online platform accessible on mobile devices. During collaboration in 3D DIEP model-making, we continuously upgraded the model to a better version. The model was modified according to the surgeon's preference from a 1:1 ratio size to a handheld size. Additionally, we achieved significant advancements over conventional methods, including improved visualization of detailed vessel pathways with separation of arteries and veins, tissue transparency, and superficial inferior epigastric vein (SIEV). Through 3D model-making collaborations, our team successfully developed a 3D DIEP model with translucency and visualized arteries and veins separately with accentuation of the perforators, including SIEV tracing, which is more accurate. This ideal 3D model for the DIEP flap enables the selection of a perforator vessel that is safe and easy to dissect to lower complications and procedure time and will be of great help to less experienced surgeons.

The enhanced-view totally extraperitoneal repair of abdominal bulge after DIEP flap breast reconstruction for breast cancer: a case report.

The deep inferior epigastric perforator (DIEP) flap for autologous breast reconstruction is associated with higher patient satisfaction and fewer abdominal morbidities at the donor site than the transverse rectus abdominis myocutaneous flap. However, abdominal bulging occurs at a certain frequency, and there is no established treatment. Here, we present a case of laparoscopic hernia repair using the enhanced-view totally extraperitoneal (eTEP) method in a patient with a lower abdominal bulge after DIEP flap reconstruction. A 53-year-old woman underwent left nipple-sparing mastectomy, left axillary lymph node dissection, and breast reconstruction with a DIEP flap for left breast cancer 3years previously. We performed an eTEP method for an abdominal bulge. The absence of a hernia sac facilitated dissection of the retrorectal space, and a left-sided transversus abdominis release was performed, followed by mesh placement. No postoperative abdominal bulging was observed. Using the eTEP method for repairing an abdominal bulge after DIEP flap reconstruction is advantageous because it facilitates a relatively straightforward dissection of a wide area of the retrorectal space without a hernia sac.

Optimal Use of Drain Tubes for DIEP Flap Breast Reconstruction: Comprehensive Review.

Background: Deep inferior epigastric perforator (DIEP) flap breast reconstruction is an increasingly popular technique, but controversy exists regarding the optimal use of closed suction drains (CSD) at the abdominal donor site. This narrative review synthesizes current evidence on CSD application, criteria for placement/removal, and complications in DIEP flap procedures. Alternative techniques and implications for postoperative care are also discussed. Methods: A systematic search was conducted in August 2024 across several databases to identify English language studies related to CSD use in DIEP flap breast reconstruction. Inclusion criteria consisted of original research on aspects such as CSD volume criteria, timing, complications, alternatives like progressive tension sutures, and impact on showering and patient outcomes. References from relevant papers were hand-searched. Results: The review found a lack of consensus on CSD protocols, with drainage volume triggering removal varying widely from 5 mL to 80 mL daily. While CSD may reduce seroma/hematoma formation, earlier removal (≤3 days) did not increase complications and shortened hospital stay. Progressive tension sutures show promise as an alternative, with evidence of comparable or reduced complications and improved recovery versus CSD. The safety of early showering with drains remains unclear. Conclusions: Although CSD aims to minimize postoperative complications, more rigorous randomized trials are needed to establish evidence-based practices for the timing of removal and demonstrate the efficacy of emerging drain-free techniques on patient-centered outcomes. Standardized criteria could reduce practice variability. Further research should also explore the long-term impact of drainage strategies on aesthetic and functional results.

Comparing Safety Profiles of Skin-Sparing and Nipple-Sparing Mastectomy With Deep Inferior Epigastric Perforator Flap Breast Reconstruction: A Retrospective Analysis.

Mastectomy is performed prior to or concurrently with deep inferior epigastric perforator (DIEP) flap breast reconstruction. However, the complication rates of nipple-sparing mastectomy (NSM) versus skin-sparing mastectomy (SSM) with DIEP are not well-characterized. This retrospective study included patients who underwent SSM or NSM with DIEP reconstruction between January 2019 and July 2022 at an academic institution. The primary outcome was 30-day postoperative complication rate. Variables were compared using Student's t-tests/Wilcoxon rank-sum and Chi-square/Fisher's exact tests. Of 535 patients, 195 (36%) underwent NSM and 340 (64%) underwent SSM. The 30-day postoperative complication rates did not differ between cohorts (16.4% in NSM vs. 16.8% in SSM, p > 0.9). The NSM cohort had a higher rate of any flap necrosis (9.2% vs. 3.5%, p = 0.01) compared to the SSM cohort, though rates of total DIEP flap loss rate did not differ (4.1% vs. 1.5% respectively). Site-wide total DIEP flap loss was 2.4%. The NSM cohort had smaller preoperative sternal notch-to-nipple distances (25.0 vs. 26.5 cm, p < 0.001) and had lower rates of preoperative radiation therapy (28.2% vs. 42.9%, p < 0.002) compared to the SSM cohort. The cohorts did not differ in demographic or operative variables including reconstruction timing (delayed vs. immediate interval), readmission, and reoperation. Individuals who received an NSM prior to DIEP reconstruction had more flap complications compared to the SSM cohort. Both cohorts had comparable overall 30-day postoperative complication rates and demographic variables, and rate of total DIEP flap loss was 2.4%. Patient preference can further guide surgical decision-making.

The Impact of Depression and Anxiety Comorbidities on Acute Postoperative Pain After DIEP Flap Breast Reconstruction.

Depression and anxiety have a complex association with opioid dependence, though their impact on acute postoperative pain is unclear. The present study investigated the impact of depression and anxiety on acute postoperative pain and opioid requirements following deep inferior epigastric perforator (DIEP) flap breast reconstruction. Patients receiving DIEP flap breast reconstruction were retrospectively identified from 2019 to 2023. Patients were classified into the psychiatric comorbidity (PC) group based on a history of depression or anxiety diagnoses, or the control group. Pain (0-10 Numerical Rating Scale [NRS]) scores and cumulative inpatient opioid requirements (in morphine milli-equivalents [MMEs]) were compared between groups. Linear regression analysis assessed the association of psychiatric comorbidities with pain outcomes. In total, 557 patients were included, of which 11.4% reported a psychiatric history. The PC group was younger (50.0 vs. 52.7 years, p = 0.032) and more frequently reported current marijuana use (15.6% vs. 4.3%, p = 0.001) and former smoking (51.6% vs. 24.5%, p < 0.001). The PC group had higher mean (2.5 vs. 2.0, p < 0.001) and maximum pain scores (8.6 vs. 7.8, p = 0.003) than the control group, which corresponded to higher opioid requirements (256 vs. 223 MMEs, p = 0.041). Psychiatric comorbidities were associated with higher average and maximum pain scores (p < 0.01) while current marijuana use was associated with higher opioid requirements (p = 0.033). Patients with depression or anxiety comorbidities tended to have greater acute postoperative pain and opioid consumption. Marijuana use was also more prevalent, potentially exacerbating pain outcomes, and risk of opioid dependence. These findings will inform patient discussions and targeted interventions to mitigate opioid misuse.

Linked Flaps of the Thoracodorsal Vascular Tree for Correcting Extensive Post-Burn Deformities and Achieving Optimal Reconstruction Outcomes.

Autologous skin grafting has been the popular method for reconstructing post-burn defects. However, this technique has limitations such as high contracture rates and inadequate volume coverage. This report aims to propose the principles and advantages of utilizing microsurgically linked perforator flaps for the reconstruction of extensive burn defects and associated post-burn scar contracture in the lower and upper extremities and trunk. Patients who underwent free tissue transfer for primary and secondary burn wound reconstruction at a single institution between 2016 and 2023 were included in the study. Patients received thoracodorsal vascular tree-linked flaps for the correction of post-burn deformities. Postoperative results were evaluated, including flap survival, complications, and the DASH self-report questionnaire for upper extremity reconstruction. Among the 20 patients, 12 required primary reconstruction, while 8 underwent secondary reconstruction using anastomotic chimeric free tissue transfer. The majority of burn injuries resulted from thermal contact (n = 8), followed by flames (n = 5), scalds (n = 4), electrical contact (n = 2), and friction (n = 1). The most frequently utilized combinations were the thoracodorsal artery perforator (TDAp) and anterolateral thigh (ALT) flap (11 cases). Additionally, four cases involved the pedicled TDAp flap in conjunction with the deep inferior epigastric artery perforator (DIEP) flap. The average DASH score for upper extremity burn patients was 10.58. Three-dimensional tissue coverage achieved through the linkage of two or even three independent free flaps is increasingly utilized in post-burn reconstruction. This approach offers multiple advantages and represents a viable option for burn reconstruction.

Comparison of Breast Sensibility Following Breast Reconstruction with Two Different Techniques: Deep Inferior Epigastric Perforator Flap and Implant

Introduction: Breast sensibility following reconstruction surgery, though often overlooked, holds significant importance due to its widespread occurrence and profound effects on patients’ well-being and safety. The author’s objective is to compare the sensory outcomes between deep inferior epigastric perforator (DIEP) flap microsurgery reconstruction and implant-based reconstruction. Additionally, the potential influence of sociodemographic and clinical factors on sensory recovery is explored, along with assessing temperature discrimination abilities and evaluating quality of life. Material and methods: An ambispective descriptive-analytical study was conducted involving women who underwent mastectomy with reconstruction using either DIEP flap and implants at the author’s hospital between 1990–2021. Data were collected from medical records, patient histories, physical examinations, and validated quality of life questionnaires (BREAST-Q). Spearman’s or Pearson’s correlation coefficients were employed for the analysis of quantitative variables, while the Student’s T test or Mann-Whitney U test were used to compare quantitative and qualitative variables. Results: A total of 99 women with breast reconstruction were included, 47 with DIEP flap and 52 with implants. Sensory recovery in implant-based reconstruction was found to be superior to DIEP flap reconstruction (5.03 and 5.18, respectively; p&lt;0.005). A direct correlation was observed between sensory improvement and thermal discrimination (Spearman coefficient 0.9; p&lt;0.001). Factors such as radiotherapy, delayed reconstruction with DIEP flap, and height with implants were associated with poorer sensory recovery in the breast. Women experiencing better breast sensibility reported higher satisfaction with their surgeon, medical team, and psychosocial quality of life. Conclusion: Women reconstructed with implants or DIEP abdominal flap exhibit suboptimal overall sensory recovery of the reconstructed breast, with slightly better outcomes observed in women reconstructed with implants. The development of novel surgical techniques aimed at enhancing sensibility after breast reconstruction could significantly benefit these patients.

Clinical Outcomes Following Profunda Artery Perforator Flap Breast Reconstruction: A Systematic Review and Meta-Analysis.

There is a lack of reliable evidence on the surgical outcomes of profunda artery perforator (PAP) flap breast reconstruction. We conducted a meta-analysis to evaluate its safety and compare it with deep inferior epigastric perforator (DIEP) flap, aiming to offer more information on whether the PAP flap was an ideal alternative for autologous breast reconstruction. PubMed, EMBASE, Web of Science and Cochrane Library were searched to retrieve relevant articles. The postoperative complication rates following PAP reconstruction were pooled. Mean differences of patients' age, BMI, mastectomy weight and flap weight between PAP and DIEP group were calculated, and relative risk was estimated to compare their incidence of complications. Twenty-four articles reporting 1612 PAP flap breast reconstructions were included. The surgical success rate was 99.6%; the incidence of total and partial flap loss was 0.4% and 0.0%; the incidence of infection, hematoma, seroma, fat necrosis and wound dehiscence in recipient sites was 0.3%, 1.4%, 1.0%, 3.3% and 0.3%, respectively; the incidence of infection, hematoma, seroma, wound dehiscence and sensory disturbance in donor sites was 2.0%, 0.9%, 3.5%, 9.2% and 0.6%, respectively. Compared to the DIEP group, the average age, BMI, mastectomy weight and final flap weight were significantly lower in the PAP group. No significant difference was observed in terms of flap failure, breast fat necrosis and donor site wound dehiscence. This systematic review demonstrates similar levels of postoperative morbidities for the PAP and DIEP flaps with some subtle differences and verifies the PAP flap as a second-line treatment for patients when the DIEP is unavailable or undesirable. This journal requires that authors assign a level of evidence to each article.

Evolution and Adaptations of Robotic DIEP Flap Surgery: A Systematic Review.

The integration of robotic technology into surgical procedures has gained considerable attention for its promise to enhance a variety of clinical outcomes. Robotic deep inferior epigastric perforator (DIEP) flap harvest has emerged as a novel approach for autologous breast reconstruction. This systematic review aims to provide a comprehensive overview of the current techniques, outcomes, and complications of robotic DIEP flap surgery. A systematic literature search was conducted after PRISMA 2020 guidelines across databases including PubMed, Embase, Google Scholar, and Web of Science from 2000 to 2023. Articles exploring robotic DIEP flap harvest for breast reconstruction were assessed to compare operative techniques, clinical outcomes, and complications. The risk of bias was evaluated using ROBINS-I and the Newcastle-Ottawa scale. Fourteen studies involving 108 patients were included. Three studies used a totally extraperitoneal (TEP) technique, whereas 11 studies used a transabdominal preperitoneal (TAPP) approach. Preoperative planning utilized computed tomography angiography and magnetic resonance angiography imaging. The mean robotic operative time was 64 minutes, with total operative times averaging 574 minutes for TAPP and 497 minutes for TEP. The mean length of stay was 5 days, and the mean fascial incision length was 3cm. Overall complication rate was 14.9%, with no significant difference compared with conventional DIEP flap procedures. Robotic DIEP flap harvest is a promising technique that may reduce postoperative pain and limiting abdominal donor site morbidity. Potential limitations include longer operative times, variable hospital stays, and increased costs.

Postmastectomy Breast Reconstruction in Irradiated Patients: A 12-year follow-up of Deep Inferior Epigastric Perforator and Latissimus Dorsi Flap Outcomes

The aim of the current study was to conduct a 12-year follow-up on the authors´ previously evaluated group of irradiated patients who underwent postmastectomy breast reconstruction with deep inferior epigastric perforator (DIEP) and latissimus dorsi (LD)-flaps with implant.The follow-up involved 67% of the patients from the original cohort (17 DIEP and 13 LD). Patient-reported outcome measures (PROMS) were measured using the BREAST-Q, SF-36, a satisfaction form, and Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaires. Aesthetics were evaluated by a board of independent plastic surgeons.The average follow-up time was 12.6 years (DIEP) and 11.8 years (LD). Contralateral symmetry procedures were performed on 15 DIEP and 9 LD patients. Both groups underwent an average of 2.5 reconstructive procedures. The BREAST-Q and satisfaction questionnaires showed no group difference. SF-36 showed no group difference but had significantly higher values in both groups compared to the general population with regard to the physical role limitations (p=0.034 and p=0.004, respectively). The DASH scores showed minimal shoulder function impact in the LD group.Aesthetic evaluations revealed a discrepancy between the opinions of the patients and surgeons, with patients valuing the size (p=0.015) and overall aesthetic (p=0.012) of the reconstructed breast higher in the DIEP group. The weighted kappa analysis showed poor agreement between patients and surgeons. Over time, the patients´ preferences shifted from LD to DIEP flaps, possibly due to the more natural aging process associated with autologous reconstruction. This underscores the importance of long term follow-up studies.

Breast reconstruction using the superficial circumflex iliac artery superficial branch perforator (SCISP) flap.

The deep inferior epigastric perforator (DIEP) flap is the gold standard for autologous breast reconstruction. One downside is its risk of postsurgical herniation and bulging due to the opening of the rectus fascia and intramuscular dissection of the rectus abdominis muscle. Additionally this part of the surgery is very time consuming. While the superficial inferior epigastric artery perforator (SIEA) flap has been thoroughly described for total autologous breast reconstruction, the use of the superficial circumflex iliac artery perforator flap in this field is limited. This series introduces the use of an extended superficial circumflex iliac artery (SCIA) perforator flap nourished solely by perforators of the superficial branch of the SCIA- artery for total autologous breast reconstruction.Superficial preparation over the abdominal wall was performed without incising the rectus fascia, dissecting the superficial branch of the SCIA and its accompanying veins and the superficial inferior epigastric vein for additional venous drainage.Four patients underwent successful autologous breast reconstruction with this extended SCIP (superficial circumflex iliac artery perforator)-flap-variation. The term superficial circumflex iliac artery superficial branch perforator (SCISP) flap was introduced to standardize the surgical technique for using only perforators of the superficial branch of the SCIA as free flaps.The SCISP flap is safe and viable for total autologous breast reconstruction, particularly for women with small to medium sized breasts and with superficial dominance of the abdominal vascular system.

Embracing Robotics in Microsurgery: Robotic-Assisted Deep Inferior Epigastric Perforator Flap Breast Reconstruction.

The integration of robotic-assisted surgery (RAS) has transformed various surgical disciplines, including more recently plastic surgery. While RAS has gained acceptance in multiple specialties, its integration in plastic surgery has been gradual, challenging traditional open methods. Robotic-assisted deep inferior epigastric perforator (DIEP) flap breast reconstruction is a technique aimed at overcoming drawbacks associated with the traditional open DIEP flap approach. These limitations include a relatively large fascial incision length, potentially increasing rates of postoperative pain, abdominal bulge, hernia rates, and core weakening. The robotic-assisted DIEP flap technique emerges as an innovative and advantageous approach in fascial-sparing abdominal autologous breast reconstruction. While acknowledging certain challenges such as increased operative time, ongoing refinements are expected to further improve the overall surgical experience, optimize results, and solidify the role of robotics in advancing reconstructive microsurgical procedures in plastic surgery. Herein, the authors provide an overview of robotic surgery in the context of plastic surgery and its role in the DIEP flap harvest for breast reconstruction.

A Meta-analysis Comparing Deep Inferior Epigastric Perforator Flaps and Latissimus Dorsi Flaps in Breast Reconstruction.

Deep inferior epigastric perforator (DIEP) flaps and latissimus dorsi (LD) flaps are two widely used breast reconstruction techniques, each with distinct advantages and limitations. This meta-analysis aims to compare patient satisfaction and incidence of complications between these two techniques to inform clinical decision-making. PubMed, Scopus, and Web of Science were searched for relevant studies. We included studies with data comparing DIEP and LD flaps, BREAST-Q patient satisfaction, and complications. Statistical analyses were performed using RevMan 5.4. The search yielded 788 studies, of which 13 were included in the meta-analysis. A total of 2128 patients were analyzed, with 1378 undergoing DIEP flap reconstruction and 750 receiving LD flap reconstruction. The analysis showed greater improvement with DIEP flaps in breast satisfaction [mean difference (MD) = 9.48, 95% confidence interval (CI) = 6.90-12.05, P < 0.00001], physical well-being (MD = 5.95, 95% CI = 2.98-8.92, P < 0.0001), and satisfaction with outcome (MD = 9.36, 95% CI = 3.01-15.71, P = 0.004). Nonetheless, DIEP flaps had higher rates of skin flap necrosis [risk ratio (RR) = 4.27, 95% CI = 2.44 to 7.46, P < 0.00001], wound dehiscence (RR = 5.12, 95% CI = 2.53-10.35, P < 0.00001), and reoperation (RR = 2.24, 95% CI = 1.58 -3.16, P < 0.00001) but lower seroma rates (RR = 0.27, 95% CI = 0.10-0.74, P = 0.01). DIEP flap reconstruction offers superior patient satisfaction compared with LD flap reconstruction, despite a higher incidence of certain complications.

Quality of Video Content Related to Deep Inferior Epigastric Perforator Flap Breast Reconstruction: Social Media Platforms Versus Large Language Models.

The deep inferior epigastric perforator (DIEP) flap is currently one of the main options in breast reconstruction. The information about this surgery is critical for the patient, in order to choose the breast reconstruction method. Our study aims to analyze and compare the quality and accuracy of the information related to the DIEP flap reconstruction method provided by social media platforms (SMPs) and the new large language models (LLMs). A total of 50 videos in English and Spanish were selected from the main SMPs (YouTube, Instagram, and Facebook) using the keywords "DIEP flap" and "colgajo DIEP." The duration, number of likes, dislikes, number of visits, upload date, author, and the video category (institutional video, media, patient experience, academic, and surgery) were analyzed. 3 specific questions were asked to 2 new LLMs (ChatGPT and Google Bard). The quality of information in SMPs and LLMs was analyzed and compared by 2 independent board-certified plastic surgeons using the Journal of American Medical Association and DISCERN scales. LLMs showed a statistically significant higher quality of information when compared with SMPs based on the DISCERN scores. The average DISCERN scores for answers given by ChatGPT and Google Bard were 54 ± 6.841 and 61.17 ± 6.306, respectively (good quality). In SMPs, the average scores were 2.31 ± 0.67 (insufficient quality) and 32.87 ± 9.62 (low quality) for the Journal of American Medical Association and DISCERN scales respectively. Thirty-eight percent of the videos in SMPs were performed by nonmedical authors. The quality of information for breast reconstruction using DIEP flaps from LLMs was considered good and significantly better than in SMPs. The information found in SMPs was insufficient and of low quality. Academic plastic surgeons have an opportunity to provide quality content on this type of reconstruction in LLM and SMPs.

Learning Curve Analysis for Robotic-assisted Harvest of Deep Inferior Epigastric Perforator Flap

Summary: The deep inferior epigastric perforator (DIEP) flap is the preferred method for autologous breast reconstruction after mastectomy, but risks the development of hernia, bulge, and decreased core strength. Robotic harvest of DIEP vessels may limit abdominal wall morbidity through smaller fascial incisions and preservation of motor nerves. This study shows the expected learning curve (LC) for robotic harvest and compares the LC between a general surgeon (GS) and a plastic surgeon (PS). A retrospective cohort study was performed for patients who underwent bilateral robotic DIEP flap harvest from October 2021 to September 2022. We evaluated robotic pedicle dissection time (DT) and compared the times between GS and PS. We calculated LC for each surgeon using the cumulative sum (CUSUM) method, . The LC was identified as the peak of the CUSUM graph. Forty-four flap dissections were recorded during the collection period: 27 by the PS and 17 by the GS. There was no significant difference in DT between the GS and the PS (P = 0.366), and both surgeons saw a decrease in DT over time. Using the CUSUM method, we see the peak of the plot at patient 9 for the PS and the peak of the plot at patient 5 for the GS, after which cumulative DT decreased. As robotic harvest of DIEP flaps becomes accepted, plastic surgeons who wish to incorporate it into their practice may achieve proficiency in their DT within 10 flap harvests and a similar DT compared with robotic-trained GSs.

A Unique Advantage of a 24-hour Surgical Delay in Autologous Breast Reconstruction.

The surgical delay technique can be used effectively in autologous breast reconstruction when there is unfavorable flap vascular anatomy or when the reconstruction necessitates a larger volume of donor tissue to obtain optimal results. The length of time between surgically delaying the flap to pedicle division and inset of the flap often varies based on surgeon preference but is typically approximately a week or longer. The authors present a case in which a 24-hour surgical delay was successfully used to augment deep inferior epigastric perforator flaps for autologous reconstruction. This technique is beneficial as it does not allow time for scarring and adhesions to develop between stages and allows for both stages to be performed in the same hospital admission.

Current status of autologous breast reconstruction in Argentina.

Although the most common procedure for breast reconstruction in Argentina is tissue expansion and implant devices, autologous tissue is frequently utilized. Deep inferior epigastric artery perforator flap (DIEP) is the gold standard for autologous breast reconstruction and, whenever possible, it is the first option. However, there are clinical or other circumstances, when a local or vicinity flaps for autologous reconstruction is preferred, even if exists a surgical and hospital facility for doing microsurgical procedures. The purpose of this manuscript is to describe our experience with the use of local and vicinity flaps for volume and surface replacement in different requirements-autologous breast reconstructions post oncologic resections, volume replacement in weight loss patients and implant-explantation cases. We have utilized the modification of latissimus dorsi musculocutaneous flap (LD) described by Hammond with excellent results and high patient satisfaction. Thoraco-dorsal artery perforator flap is indicated on skin sparing mastectomies (SSMs), immediate reconstruction of the nipple areolar complex and simultaneous coverage of an implant or tissue expander, in irradiated or to be irradiated patients. Lateral intercostal artery perforator (LICAP) flap has gained popularity because the unique position of the perforator at the lower lateral corner of the breast. It allows harvesting immediate vicinity tissue and easy rotation to the breast mound. We have used a modification towards the lateral thoracic wall of the anterior intercostal artery perforator flap for volume reconstruction after implant explantation.in patients who required volume preservation. Medial intercostal artery perforator flap is advantageous whenever the sub-mammary tissue can be used deepithelialized for volume reconstruction with a medial base. The same submammary area harvested as a medially based flap can be irrigated by the LICAP as a reverse LICAP flap that might be designed toward any direction from the piercing point of its perforator. The rest of the donor areas described for breast autologous reconstruction are rarely reported. When surgical facilities and adequate surgical teams are available, the lower abdominal wall is the main donor area, and DIEP, the most common technique utilized.

Global perspectives on practices and preferences in Autologous Free Flap Breast Reconstruction: From flap selection to post-operative care: A descriptive quantitative study

BackgroundThe purpose of this study was to evaluate present-day practices in the preparation, peri- and post-operative care for autologous free-flap breast reconstructions (ABR) worldwide, with the aim of enhancing informed decision-making for plastic surgeons during the planning stages of ABR. MethodsA global survey was conducted among 280 plastic surgeons and 39 plastic and reconstructive surgery societies worldwide, inquiring about the flap and donor site selection, surgical actions, perforator imaging and peri-operative care during ABR. ResultsEighty-two responses were received, of which 71% (n=58) were completed questionnaires. The preferred flap choice was the Deep Inferior Epigastric Perforator (DIEP) flap (85%, n=51), with the internal mammary artery as the most commonly used recipient vessel. Pre-operative imaging for ABR was typically performed using Computed Tomography Angiography (75%, n=44) and often combined with a handheld doppler. Handheld doppler was the most frequently used modality to localize perforator vessels during surgery (33%, n=19), with the majority using either one (47%, n=24) or two (51%, n=26) perforators intraoperatively. These preferences were consistent across all clinic types.Post-operatively, flap monitoring was primarily performed by the nursing staff, initially every hour on the first day and then at reduced frequencies on subsequent days.The most commonly used modality for monitoring flap viability was the handheld doppler. The average length of hospital stay was five days. ConclusionThis study provides valuable insights into current preparations, peri- and post-operative care in ABR procedures worldwide, aiding in the development of standardized practices and potentially improving patient outcomes.

Hug Flap and Hamdi Hammock: Two Innovative Techniques for Enhancing Aesthetic Outcomes in Deep Inferior Epigastric Artery Perforator Breast Reconstruction.

Achieving optimal aesthetic outcomes in deep inferior epigastric artery perforator (DIEP) flap breast reconstruction remains a challenge, often necessitating additional procedures for refinement. This study presents two innovative techniques (the hug flap and Hamdi hammock) aimed at enhancing breast projection and inframammary fold (IMF) definition in DIEP flap reconstruction. The hug flap technique uses de-epithelialized caudal mastectomy skin to augment breast projection, whereas the Hamdi hammock uses a percutaneous purse-string suture to define the IMF. A retrospective review of 782 patients who underwent DIEP flap breast reconstruction between 2007 and 2023 was conducted. The hug flap group required significantly less additional fat grafting compared to other techniques (11% versus 27% and 22%). No total flap losses occurred in the hug flap group, and fat necrosis rates were low. The Hamdi hammock was used in 405 patients with a mean of two lipofilling sessions. Complications were minor and no stitches required removal. The hug flap and Hamdi hammock techniques offer effective and safe methods for enhancing breast projection and IMF definition in DIEP flap reconstruction. These techniques may reduce the need for additional procedures and improve aesthetic outcomes.

Gender-affirming DIEP Flap Breast Augmentation.

Implant-based techniques have been the mainstay of gender-affirming breast augmentation (GABA). Here we describe a novel autologous technique for GABA. We provide a single-patient case report of gender-affirming deep inferior epigastric artery perforator (DIEP) flap breast augmentation. World Professional Association for Transgender Health guidelines were followed according to Standards of Care, version 8. Prepectoral tissue expanders were placed at the time of the patient's facial feminization surgery. DIEP flaps were then used for bilateral breast augmentation. Planned revisions were made about 5 months later. Breast augmentation was performed successfully with DIEP flaps, and the patient was satisfied with her outcome. No complications occurred. Anatomic differences to cisgender women were noted, including relatively thick musculature of the abdominal wall and chest as well as tight anterior abdominal fascial closure. Advantages compared with implant-based GABA were also noted, including feminization of the abdomen and avoidance of potential implant related complications. We report a novel approach to GABA. Our approach borrows well-established techniques with demonstrated efficacy and high satisfaction in postmastectomy breast reconstruction and even cosmetic purposes. However, sex- and hormone-influenced anatomic differences required some modifications compared with postmastectomy DIEP flap reconstruction.
