Propeller thoracodorsal artery perforator flap for breast reconstruction

Optimizing thoracodorsal artery perforator flap outcomes in oncoplastic breast surgery: multidimensional assistive techniques mitigate learning curve and enhance feasibility

This study aims to evaluate the feasibility and postoperative outcomes of the thoracodorsal artery perforator (TDAP) flap in oncoplastic breast surgery (OBS), incorporating multidimensional assistive techniques. We retrospectively analyzed 14 breast cancer patients treated with TDAP flap OBS from May 2020 to August 2023. Patients were divided into two groups: Group A (first 7 cases) and Group B (last 7 cases). Preoperative perforator localization was performed using color Doppler ultrasound and handheld Doppler, with intraoperative comparisons. Blood perfusion was assessed intraoperatively with indocyanine green (ICG) fluorescence imaging and postoperatively with infrared thermal (IRT) imaging. Patient satisfaction was measured using the BREAST-Q scale. Group A had longer operation times (4.05 ± 0.61 h vs. 3.27 ± 0.31 h, P = 0.011) and longer hospitalization (9.14 ± 2.27 days vs. 7.71 ± 1.60 days, P = 0.199). No flap necrosis occurred. Preoperative and intraoperative perforator positions were consistent. ICG imaging showed good flap blood supply; edge trimming improved perfusion in two cases. IRT imaging confirmed good blood perfusion in the first 3 days post-op. BREAST-Q scores for psychological health and sexual satisfaction were lower post-op (P < 0.001), but no significant differences were found in scores for chest physical health, shoulder and back physical health, or breast satisfaction. While TDAP flap surgery involves a learning curve, it is a highly feasible technique for OBS. Multidimensional assistive technologies significantly enhance preoperative perforator localization and intraoperative flap blood perfusion monitoring, thereby improving flap survival rates and patient satisfaction.

Microsurgical breast reconstruction in the United States: a narrative review of the current state

Background and Objective

Breast reconstruction with microsurgical techniques allows for autologous reconstruction after mastectomy without the complications associated with alloplastic reconstruction. Autologous reconstruction has undergone significant improvement and now offers patients a variety of options depending on patient specific factors and aesthetic outcomes. This review aims to focus on the history of autologous reconstruction, operative considerations, general surgical techniques for flaps, and indications for choosing the ideal free tissue transfer for all medical specialties and not only plastic surgeons.

Methods

A comprehensive review of the literature was performed using PubMed and Embase databases. Manuscripts that provided objective data with respect to history of microsurgical options, surgical techniques, patient considerations, and contraindications were utilized for this review with the objective to simplify data for all non-plastic surgeon readers.

Key Content and Findings

In this study, we find that patient selection is critical in successful outcomes for microsurgical breast reconstruction. We find that abdominal free flaps are now considered gold standard for autologous reconstruction. However, reliable alternatives exist for patients who are not considered ideal candidates for this reconstruction. These include thigh-based flaps such as gracilis myocutaneous flaps, profunda artery perforator flaps, lateral thigh perforator flaps and trunk-based flaps such as lumbar artery perforator flap. Postoperative considerations involve clinical monitoring and enhanced recovery after surgery. The rate of reconstructive success and flap viability is greater that 95%, even in high-risk populations, and therefore risk stratification should be performed based on an individual basis. While there are no absolute contraindications to autologous reconstruction, relative contraindications do exist including obesity and elderly populations due to the increased surgical and medical complications.

Conclusions

While implant-based reconstruction remains the predominant method of breast reconstruction in the United States, there have been many exciting advancements in autologous reconstruction that offers high aesthetic outcomes and patient satisfaction.

Combined perforator flaps for total breast reconstruction-a narrative review and insights from massive weight loss cases

Background and Objective

Perforator flaps have revolutionized autologous breast reconstruction, introducing both free and pedicled options as well as the potential for combining flaps. These versatile techniques can be utilized in massive weight loss (MWL) patients, effectively addressing both functional and aesthetic challenges by using their excess skin. This review aims to explore literature on combined pedicled and free perforator flaps for total breast reconstruction, and share our own experience in the field.

Methods

A PubMed search up to June 2023 employed Medical Subject Headings (MeSH) terms such as (("combined") OR ("stacked") OR ("conjoined") AND ("perforator flaps")) AND ("breast reconstruction"). Publications in English and Scandinavian languages were manually screened for relevance, and supplemental sources were also reviewed.

Key Content and Findings

Limited studies exist on using combined pedicled and free flaps for total breast reconstruction, although combined free flaps are more common. Perforators around the breast base, offer multiple flap options for single or combined use. In our series of 10 women, four underwent total breast reconstruction with a combination of flip-over internal mammary artery perforator (IMAP) flap and thoracodorsal artery perforator (TDAP) flap. Another subset of four, who were MWL patients, received combined TDAP and superior epigastric artery perforator (SEAP) flaps, along with body contouring procedures such as upper body lifts and vertical abdominoplasties, addressing excess skin and improving silhouette. One remaining MWL patient had deflated breasts restored using TDAP and SEAP flaps, along with an upper and lower body lift and vertical abdominoplasty. The last MWL patient underwent a risk-reducing mastectomy, also reconstructed with TDAP and SEAP flaps, and received an upper body lift and vertical abdominoplasty.

Conclusions

Combined perforator flap techniques for combined body contouring and breast reconstruction seems safe and especially suitable for MWL patients. They offer a surgical alternative merging body contouring and breast reconstruction in cases where free flap procedures seem less favorable due to skin laxity and deflation of donor sites. However, limited literature on the topic calls for further studies.

Breast reconstruction with latissimus dorsi flap: a comprehensive review and case series

The latissimus dorsi flap (LDF) has gained popularity given its versatile nature and broad applicability in breast reconstruction. Its resurgence has been attributed to its ability to be enhanced using implant or high-volume fat grafting, rendering it a primary option for selected patients. The aim of this review is to tackle current indications and subjects of controversy regarding use of complete-autologous and implant-enhanced LDF in breast reconstruction. Also, a case-series showcasing the authors' experience with this versatile reconstructive option is presented. A search across Web of Science and PubMed MEDLINE from inception through January 3, 2023, was conducted. Articles reporting postoperative outcomes of autologous breast reconstruction with LDF were included. Regarding the case series, electronic medical records of patients who underwent total mastectomy and autologous breast reconstruction with LDF from January 2011 to December 2021 were retrospectively reviewed. Data on demographic and oncologic characteristics, and surgical characteristics and outcomes were extracted. Our review suggests that LDF is suitable for patients who lack alternative donor site, have a history of abdominoplasty or no access to microsurgery, smokers or obese. Latissimus dorsi (LD) harvesting has almost complete shoulder function recovery in the long-term. Thoracodorsal nerve division does not cause volume loss or animation deformity. Multisite multilayer fat grafting, beveling the edges of the skin paddle and fat, folding the LD muscle and plicating the paddle allow adequate projection and contour achievement. Our case-series included 234 reconstructions. Almost half of the patients had immediate fat transfer during reconstruction (51.3%). The rate of recipient site hematoma was 3.0%, seroma was 7.7%, wound disruption 32.1%, wound disruption events requiring unplanned procedures was 13.7%, and surgical site infection (SSI) was 12.4%. The LDF is reliable and safe for immediate or delayed breast reconstruction or salvage after reconstruction failure. Its versatility, reliable anatomy, easy dissection, and relative low complication rate have revived this modality as valuable opportunity for breast reconstruction in this era.

[Clinical application effects of two longitudes three transverses method in perforator location of thoracodorsal artery perforator flap and deep wound repair]

Objective: To explore the clinical application value of two longitudes three transverses method in the location of the perforator of thoracodorsal artery perforator and deep wound repair. Methods: The retrospectively observational study was conducted. From December 2018 to June 2020, 17 patients with deep wounds who were admitted to the Affiliated Hospital of Zunyi Medical University met the inclusion criteria and were included in this study, including 7 males and 10 females, aged 12 to 72 years. The wound areas of patients after debridement were 7 cm×3 cm to 11 cm×7 cm. Two longitudinal lines were located through the midpoint of the armpit, the posterior superior iliac spine, and the protruding point of the sacroiliac joint, and three transverse lines were located 5, 10, and 15 cm below the midpoint of the armpit between the two longitudinal lines, i.e. two longitudes three transverses method, resulting in two trapezoidal areas. And then the thoracodorsal artery perforators in two trapezoidal areas were explored by the portable Doppler blood flow detector. On this account, a single or lobulated free thoracodorsal artery perforator flap or flap that carrying partial latissimus dorsi muscle, with an area of 7 cm×4 cm to 12 cm×8 cm was designed and harvested to repair the wound. The donor sites were all closed by suturing directly. The number and location of thoracodorsal artery perforators, and the distance from the position where the first perforator (the perforator closest to the axillary apex) exits the muscle to the lateral border of the latissimus dorsi in preoperative localization and intraoperative exploration, the diameter of thoracodorsal artery perforator measured during operation, and the flap types were recorded. The survivals of flaps and appearances of donor sites were followed up. Results: The number and location of thoracodorsal artery perforators located before operation in each patient were consistent with the results of intraoperative exploration. A total of 42 perforators were found in two trapezoidal areas, with 2 or 3 perforators each patient. The perforators were all located in two trapezoid areas, and a stable perforator (the first perforator) was located and detected in the first trapezoidal area. There were averagely 1.47 perforators in the second trapezoidal area. The position where the first perforator exits the muscle was 2.1-3.1 cm away from the lateral border of the latissimus dorsi. The diameters of thoracodorsal artery perforators were 0.4-0.6 mm. In this group, 12 cases were repaired with single thoracodorsal artery perforator flap, 3 cases with lobulated thoracodorsal artery perforator flap, and 2 cases with thoracodorsal artery perforator flap carrying partial latissimus dorsi muscle. The patients were followed up for 6 to 16 months. All the 17 flaps survived with good elasticity, blood circulation, and soft texture. Only linear scar was left in the donor area. Conclusions: The two longitudes three transverses method is helpful to locate the perforator of thoracodorsal artery perforator flap. The method is simple and reliable. The thoracodorsal artery perforator flap designed and harvested based on this method has good clinical effects in repairing deep wound, with minimal donor site damage.

Thoracodorsal artery flaps for breast reconstruction-the variants and its approach

Thoracodorsal artery (TDA) flaps, ranging from the vascular-pedicled thoracodorsal artery perforator (TDAP) flap, the propeller TDAP flap, and the muscle-sparing latissimus dorsi (MSLD) flap to the conventional latissimus dorsi (LD) flap and the extended LD flap, can all be used for breast reconstruction. The aim of this paper and review is to share our experiences and recommendations for procedure selection when applying TDA-based flaps for breast reconstruction. We describe the different surgical techniques and our thoughts and experience regarding indications and selection between these procedures for individual patients who opt for breast reconstruction. We have performed 574 TDA flaps in 491 patients: 60 extended LD flaps, 122 conventional LD flaps, two MSLD flaps, 233 propeller TDAP flaps, 122 TDAP flaps, and 35 free contralateral TDAP flaps for stacked TDAP breast reconstruction. All the TDA flaps are important flaps for reconstruction of the breast. The LD flap is still an option, although we prefer flaps without muscle when possible. The vascular-pedicled TDAP flap is an option for experienced surgeons, and the propeller TDAP flap can be used in most reconstructive cases of the breast, although a secondary procedure is often necessary for correction of the pedicle bulk. The extended LD flap is an option for women with a substantial body mass index, although it is associated with the highest morbidity of all the TDA flaps. The MSLD flap can be used if the perforators are small or if dissection of the perforators is assessed to be hazardous.

Thoracodorsal Artery Perforator Flap in Partial Breast Reconstruction: A Systematic Review

Breast conserving surgery followed by radiation therapy represents the standard of care for early stage breast cancer. Oncoplastic breast surgery includes several reconstructive techniques essentially summarized in 2 categories: volume displacement and volume replacement procedures. These latest procedures have evolved over time from the use of the entire latissimus dorsi muscle to the use of pedicled perforator flaps, namely the thoracodorsal artery perforator (TDAP) flap. The aim of this article is to provide a comprehensive review of the literature regarding the use of the TDAP flap in partial breast defects.

The Value of Dynamic Infrared Thermography in Pedicled Thoracodorsal Artery Perforator Flap Surgery

Dynamic infrared thermography (DIRT) is a noninvasive imaging technique that can provide indirect and real-time information on skin perfusion by measuring skin temperature. Although used in flap surgery, there are no reports on its value in procedures using a pedicled thoracodorsal artery perforator (TDAP) flap. The aim of this study was to assess the usefulness of DIRT in preoperative perforator mapping and in monitoring intra- and postoperative flap perfusion of pedicled TDAP flaps.

Visualized bilateral breast reconstruction by propeller thoracodorsal artery perforator flaps

Thoracodorsal artery perforator (TAP) flaps are versatile flaps that provide a consistent and aesthetically pleasing breast reconstruction. We prefer the TAP flap to the latissimus dorsi (LD) flap due to the morbidity associated with the LD flap. In this paper we aim to show how we perform bilateral TAP flap breast reconstruction and present our preliminary results from 32 bilateral reconstructions in 16 patients. The TAP flap breast reconstruction can be performed as a direct-to-implant or a delayed procedure depending on patient factors. Color Doppler ultrasonography (CDU) is used in the preoperative planning which promotes the safety and reliability of the flap by mapping perforators thus enabling faster dissection. The bilateral TAP flap breast reconstruction is usually performed in three steps: (I) raising the flaps at the recipient site; (II) rotating the TAP flaps and (III) completion of the breast reconstruction.

The Posterior Arm Flap for Reshaping the Postbariatric Breast

Postbariatric surgery, either by itself or in association with other procedures, tries to correct physical defects and body deformities. Because of the intrinsic complexity of massive weight loss (MWL) patients, more than a single procedure is, most of the time, required. We report a combined surgical method able to improve arms' and breasts' contour that aims to obtain a satisfying functional and aesthetic result by reducing surgical times and costs.

Methods

A female MWL patient with proper body mass index was clinically evaluated and considered suitable for surgery. While authors performed a modified Pascal-Le Louarn brachioplasty for the upper arm, a standard McKissock mastopexy followed by a Wise pattern skin closure was selected to obtain the breast lift. By sparing the proximal pedicle, the fasciocutaneous flaps were harvested on both posteromedial sides of the arms. The posterior arm flaps (PAF) were tunneled and transposed below the subcutaneous skin bridge across the axilla and finally used to increase the breast mound.

Results

In the immediate postoperative follow-up, no complications were reported. After the 6-month and 1-year follow-up, both arms' silhouette was documented as healthy and symmetric. Breasts were soft, without any signs of ptosis and/or contracture. No skin disorders or scar hypertrophy or lymphedema were reported.

Conclusions

PAF in breast contouring procedures is an interesting surgical option, but more patients need to be treated to validate the effectiveness of the procedure. This technique should be considered when there is a need for simultaneously improving arm's contour and breast's volume and shape.

Thoracodorsal artery perforator flap as an autologous alternative to acellular dermal matrix

Background

Thoracodorsal artery perforator (TDAP) flap is one of the relatively new techniques in breast reconstruction. This pedicled flap retains the benefits of perforator flaps as regards minimal donor site morbidity without the need for microvascular anastomosis. Its role in partial breast reconstruction has been well documented. However, there are few reports about the role of this flap in total breast reconstruction.

Methods

This study included 47 cases who presented to the breast unit of the National Cancer Institute of Cairo University from 2013 to 2015. All patients underwent nipple-sparing mastectomy with immediate implant-based reconstruction. The TDAP flap was used to complete the subpectoral pocket for the implants in a way similar to the acellular dermal matrix.

Results

Overall complication rate was 14.9%. Capsular contracture occurred in 6.4%.There were no donor site complications. The majority of patients were satisfied with their cosmetic results. Sixty-eight percent rated their result as “excellent” or “good.”

Conclusion

Thoracodorsal artery perforator flap can play a significant role in total breast reconstruction. In settings with limited resources, this flap can serve as an available autologous alternative to acellular dermal matrix.

Extended thoracodorsal artery perforator flap for breast reconstruction

A total of 45 patients underwent partial or total autologous breast reconstruction after skin-sparing mastectomy, skin-reducing mastectomy, and quadrantectomy using a thoracodorsal artery perforator (TDAP) flap. The detailed surgical technique with its variations is explained in this report. The propeller, flip-over, conventional perforator, and muscle-sparing flaps have been described and evaluated. The flaps were partially or completely de-epithelialized. The conventional TDAP can be enlarged or "extended" as the traditional latissimus dorsi musculocutaneous (LD-MC) flap by incorporating the superior and inferior fat compartments. It can be referred to as the "extended TDAP flap". This technique augments the flap volume. In addition, this flap can serve as a scaffold for lipofilling to obtain autologous breast reconstruction in medium to large cases. There were two complete failures due to technical errors during flap elevation. Distal partial tissue suffering was observed in four flaps. These flaps were longer than usual; they reached the midline of the back. It is advisable to discard the distal medial quarter of the flap when it is designed up to the midline to avoid steatonecrosis or fibrosis. A retrospective analysis of the 39 flaps that survived completely revealed a satisfactory result in 82% of the cases. The main disadvantage of this procedure is the final scar. The TDAP flap is a reliable and safe method for partial or total breast autologous reconstruction.

Bilateral Breast Reconstruction with Extended Thoracodorsal Artery Perforator Propeller Flaps and Implants

We present our experience of bilateral total breast reconstruction using a double-sided extended thoracodorsal artery perforator propeller flap in a case series of 10 patients. Reconstruction was successfully achieved in all cases with few complications. The median time for surgery was 275 minutes (200–330), and the average implant size used was 350 cm³ (195–650). We demonstrate how the extended thoracodorsal artery perforator propeller flap allows for a swift and reliable direct to implant bilateral total breast reconstruction in a simple setting and is a valuable adjunct to our armamentarium of techniques for single-stage bilateral breast reconstruction.

The evolving breast reconstruction: from latissimus dorsi musculocutaneous flap to a propeller thoracodorsal fasciocutaneous flap

The aim of this editorial is to give an update on the use of the propeller thoracodorsal artery perforator flap (TAP/TDAP-flap) within the field of breast reconstruction. The TAP-flap can be dissected by a combined use of a monopolar cautery and a scalpel. Microsurgical instruments are generally not needed. The propeller TAP-flap can be designed in different ways, three of these have been published: (I) an oblique upwards design; (II) a horizontal design; (III) an oblique downward design. The latissimus dorsi-flap is a good and reliable option for breast reconstruction, but has been criticized for morbidity and complications. The TAP-flap does not seem to impair the function of the shoulder or arm and the morbidity appears to be scarce. However, an implant is often needed in combination with the TAP-flap, which results in implant related morbidity over time. The TAP-flap seems to be a promising tool for oncoplastic and reconstructive breast surgery and will certainly become an invaluable addition to breast reconstructive methods.
