Improved flap perfusion and hemostasis after postoperative embolization in free flap surgery: a case report

This study aims to present a novel use of coil embolization in managing postoperative bleeding after free flap surgery, a technique typically reserved for other medical complications. We report the case of a 77-year-old female patient who underwent muscle-sparing latissimus dorsi free flap surgery for recurrent myxofibrosarcoma on her left thigh. Although hemostasis was achieved hemostasis during surgery, the patient experienced postoperative bleeding, which was initially managed with compression and blood transfusions. Upon a critical drop in the hemoglobin level, coil embolization was performed at the proximal segment of the descending branch of the lateral circumflex femoral artery. Coil embolization successfully controlled bleeding, while preserving blood flow to the flap. The patient’s hemoglobin levels stabilized, and the flap’s perfusion improved post-procedure. This approach proved effective in managing bleeding in areas other than the anastomosis site, with the patient showing a satisfactory recovery and no significant complications in the 30-day postoperative period. Coil embolization, a method commonly used for gastrointestinal bleeding and other vascular issues, can be a viable and effective option for controlling postoperative bleeding after free flap surgery. This case demonstrates its potential as a lifesaving intervention while preserving flap viability. However, further research with more cases is needed to evaluate the generalizability and long-term outcomes of this technique in similar surgical contexts.

Enhancing Viability of the Muscle-Sparing Latissimus Dorsi Flap

Aim:The aim of this study is to enhance the viability of the muscle-sparing latissimus dorsi flap. In this study, the muscle-sparing latissimus dorsi myocutaneous flap was designed with the skin paddle of the flap over the distal perforators of the thoracodorsal artery and perforators of the 10th or 11th posterior intercostal arteries. The flap was elevated together with the deep fascia at the base. Methods: Sixteen flaps were used for the repair of defects in different regions in 14 patients, five female and nine male, with a mean age of 45 years. Flap sizes vary from 9x21 to 14x27 cm. The defects were located in anterior thoracic wall in patient four, arm in patient three, axillary fossa in patient three, deltopectoral region in patient two and posterior thoracic wall in patient two. The mean follow-up period was 13 months. Result: All flaps survived without total or partial loss. Seroma or contour deformity in the donor area did not develop. A visible scar developed in the donor area in a patient. Flap thinning was performed on two flaps. In all patients, shoulder joint function returned to normal in the last months postoperatively. Conclusions: If the muscle-sparing latissimus dorsi flap is prepared to include the skin paddle 10th or 11th posterior intercostal arteries and together with the deep fasciae (dorsal thoracic fascia and scarpa’s fascia), it can be safely elevated large sizes.

Combining Wise-pattern Volume Displacement and Autologous Volume Replacement to Facilitate Oncoplastic Breast Conservation

Background: Oncoplastic breast conservation has been classically divided into volume displacement (VD) or volume replacement (VR) techniques. There have been few descriptions of merging these two approaches. This report describes our experience combining Wise-pattern VD and autologous VR to repair extensive partial mastectomy defects in patients with ptosis. Methods: A retrospective chart review was performed for patients who underwent combined Wise-pattern VD surgery and autologous VR by the author from June 2017 to June 2023, with at least 6 months follow-up. Patient demographics, oncological and intraoperative details, and complications were recorded. Results: Forty patients underwent Wise-pattern VD surgery combined with a medial intercostal artery perforator flap (five patients), lateral thoracic artery perforator/lateral intercostal artery perforator flap (18 patients), anterior intercostal artery perforator flap (five patients), or muscle-sparing latissimus dorsi flap (12 patients). The average tumor size was 4.0 cm (range, 1.5–9.1 cm), and specimen weight was 152 g (range, 33–415 g). Six patients (15%) required re-operation for positive margins. There was delayed healing of three (7.5%) donor sites. There were no flap failures. Two (5%) patients had clinically apparent fat necrosis without requirement for surgical revision. Conclusions: This report demonstrates the feasibility of combining Wise-pattern VD and autologous VR. We propose that oncoplastic breast-conserving surgery be no longer divided into two mutually exclusive approaches and that surgeons make liberal use of combining these approaches to address challenging cases of breast-conserving surgery.

Impact of the withdrawal of macrotextured implant on reconstruction practices

On 22 November 2018, the French Society for Plastic, Reconstructive and Aesthetic Surgery recommended that Allergan® macrotextured breast implants be recalled, a decision endorsed by the French national health products safety agency (ANSM) on 2nd April 2019. At the Georges-François Leclerc Cancer Center (CGFL) in Dijon, we decided to stop using macrotextured implants as of November 2018 in favor of smooth implants. The purpose of this study is to evaluate the impact of the recall of macrotextured implants on breast reconstruction surgical practices and their complications. This is a single-centre, retrospective study performed at the CGFL in Dijon, France. Reconstruction techniques and complications were compared between two periods, i.e. before the recall of macrotextured breast implants (period 1: 1st September 2017-November 22, 2018) and after the recall (period 2: 23 November 2018-31st March 2020). All patients who underwent breast reconstruction for the first time were included. Data were collected from 168 reconstructions in period 2, and 159 in period 2. The rate of use of breast implants during reconstructions decreased significantly in period 2 (53.6% vs. 23.9%; P<0.001). The rate of autologous reconstructions increased significantly for muscle sparing latissimus dorsi (2.4% vs. 12.6%; P<0.001) and exclusive fat grafting (9.5% vs. 21.5%; P<0.01). Clavien-Dindo Stage IIIb complications decreased in period 2 (10% vs. 18.4%; P=0.04). Since the recall of macrotextured breast implants, the reconstruction rate has decreased in our centre in favor of autologous techniques with lower complication rates.

Abstract P2-15-10: Impact of the withdrawal of textured breast implants from the market on breast reconstruction practices

Abstract Background: In November 2018, the SOFCPRE (Société Française de chirurgie plastique, reconstructrice et esthétique) recommanded that textured Biocell© implants should no longer be used because of a potential risk of anaplastic large cell lymphoma (ALCL). This decision was confirmed in April 2019 by the French Medicines Agency (ANSM, Agence nationale de sécurité du médicament), and the French Medical Regulatory Authority. In the Georges-François Leclerc Cancer Center (Dijon, France), we suspended the use of textured Biocell© implants from November 2018 onwards, in favour of smooth surface, round implants. Objective: To assess the impact of textured implant withdrawal on surgical practices in breast reconstruction (BR) in a single French cancer center. Methods: This is a retrospective, single-centre study in the Georges-François Leclerc Cancer Center (Dijon, France). Surgical practices of BR and complications were compared between 2 periods: before the withdrawal of textured implants from the market (Period 1: September 2017-November 2017) and after (Period 2: December 2018-March 2020). Patients were included if they were operated on for the first time for immediate or secondary BR in either period. Univariate analysis was performed to compare before vs after groups, and to analyse surgical practices (rates of autologous techniques and breast implant) of BR and complications ((defined as any complication grade IIIB or higher according to the Clavien Dindo classification) between the 2 periods. Results: Data from 168 and 159 BR were collected from Periods 1 and 2 respectively. Characteristics were comparable between groups.The rate of BR with implants was significantly lower in period 2 compared with period 1 (23.9% vs 53.6%; p&amp;lt; 0.001). Similarly, autologous BR increased significantly in period 2 for muscle sparing latissimus dorsi (2.4% vs 12.6%; p&amp;lt; 0.001) and exclusive fat grafting (9.5% vs 21.5%; p&amp;lt; 0.01). Others autologous techniques was comparable between the two periods (DIEP and latissimus dorsi). The number of complications decreased in period 2 (10% vs 18.4% in period 1, p=0.04). Conclusion: After the withdrawal of textured implants, we observed a significant change in surgical practices for BR in our center. The rate of reconstruction with implants decreased in favour of autologous techniques. This change in practice was accompanied by a decrease in complications.

Reduction of morbidity in reconstruction after soft tissue sarcoma of the limb using muscle sparing latissimus dorsi

Reduction of morbidity in reconstruction after soft tissue sarcoma of the limb using muscle sparing latissimus dorsi

Morbidity and quality of life following breast reconstruction by autologous latissimus dorsi flap, muscle sparing latissimus dorsi flap and thoracodorsal artery perforator flap

Background: Morbidity following autologous latissimus dorsi flap (ALD), muscle sparing latissimus dorsi flap (MSLD) and thoracodorsal artery perforator flap (TAP) is controversial. The purpose of this study was to measure morbity using Quick Dash at 1 month and 1 year following breast reconstruction with one of these three flaps. The second objective was the evaluation of quality of life using Breast-Q.

Morbidité et qualité de vie après reconstruction mammaire par lambeau de grand dorsal autologue, à épargne musculaire et perforant

Morbidity following autologous latissimus dorsi flap (ALD), muscle sparing latissimus dorsi flap (MSLD) and thoracodorsal artery perforator flap (TAP) is controversial. The purpose of this study was to measure morbity using Quick Dash at 1month and 1year following breast reconstruction with one of these three flaps. The second objective was the evaluation of quality of life using Breast-Q. Thirty four consecutive patients who had undergone breast reconstruction were included in this monocentric and prospective study: 10patients in the ALD group, 12patients in the MSLD group and 12patients in the TAP group. At 1month and 1year following surgery, the variation of Quick Dash was 13,63and 2,38in the ALD group, 3,41and -1,13in the MSLD group and 5,69and 0in the TAP group. Satisfaction whith breasts, psychosocial, sexual and chest well-being were higher in the ALD group. Satisfaction with back was higher in the MSLD and TAP groups. Back and shoulder well-being was comparable regardless of the flap. Seroma occurrence was very rare in case of TAP, rare and not abundant in case of MSLD and frequent in case of ALD. This study appears to confirm that immediate morbidity is less important with MSLD or TAP than ALD. Hoewever at one year following surgery, morbity seems to be comparable with the 3flaps. Patients satisfaction seems to be higher with ALD except for the aspect of the back.

Pre-expanded muscle-sparing Latissimus Dorsi free flap: An ideal option for the reconstruction of extensive anterior knee contractures

Extensive and complex contractures in the anterior knee area can pose a significant challenge for reconstruction due to insufficient skin and soft tissue coverage and poor cosmetic and functional outcomes using traditional methods. We presented our experience with pre-expanded muscle-sparing latissimus dorsi (LD) free flap as an alternative option for large-scale anterior knee reconstruction. From January 2016 to December 2020, we applied this surgical technique in six patients with large postburn or post-traumatic contractures of the anterior knee. After tissue expansion of several months, the expanded muscle-sparing LD free flap was harvested and transferred to resurface the lesions. Operative procedures, postoperative complications, and long-term outcomes were evaluated. A total of six patients aged 7 to 32 years (mean: 20 years) were reconstructed successfully without any major complication. The flap ranged from 20×8cm to 40×16cm. All donor sites were primarily closed. Follow-up (range: 12 to 24 months) evaluation showed satisfactory results in both cosmetic and functional aspects. Pre-expanded muscle-sparing LD free flap is a reliable and effective choice for extensive anterior knee contracture reconstruction with satisfactory esthetic and functional outcome. It can provide substantial amount of soft tissue coverage with minimal complications and donor-site morbidity. Furthermore, it offers a good basis for next-step orthopedic surgery, such as total knee arthroplasty (TKA).

Salvage of infected implant-based breast reconstructions in morbidly obese patients with explantation and replacement with an autologous muscle-sparing latissimus dorsi flap

Morbidly obese patients who undergo reconstruction with implants after mastectomy are at higher risk of reconstructive failure. Prosthetic infection historically required explantation with plans for delayed implant-based reconstruction or conversion to autologous tissue. Loss of the skin envelope in the delayed setting often leads to poor aesthetic outcomes. Recently, several different approaches for salvage of infected implant-based reconstructions with immediate prosthetic replacement have been described. While these strategies have proven useful in many patients, we find a prohibitive risk of failure of this approach in the morbidly obese, especially in those undergoing chemotherapy or who have been radiated. Instead, we have offered these patients salvage of their reconstructions with explantation and immediate autologous conversion to a muscle-sparing latissimus dorsi flap. Here, we report on 11 morbidly obese patients where this strategy was utilized.

Optimizing Aesthetics in Reconstructive Breast Surgery Using Muscle-Sparing Latissimus Dorsi Flap in Radiated and Nonradiated Patients.

The latissimus dorsi musculocutaneous flap (LDMF) has been a workhorse for breast reconstruction. Its high rate of donor-site morbidity has led to the advent of the muscle-sparing latissimus dorsi flap (MSLDF). However, there are very limited reports using the MSLDF in irradiated patients. Prior studies of MSLDF have either precluded previously radiated patients from receiving MSLDF or have included them as part of their larger MSLSDF cohort without specifically analyzing their outcome as a separate group or comparing them to the traditional LDMF group. We describe the technique and outcome of MSLDF in both radiated and nonradiated patients and compare the outcome to our LDMF patients. A retrospective chart review of patients undergoing breast reconstruction between 2003 and 2020 using either a pedicled MSLDF or LDMF with a transverse skin paddle was conducted. All patients underwent a 2-stage reconstruction with the flap and tissue expander placement done during the first stage, and replacement with implant and, if needed, fat grafting to enhance soft tissue during the second stage. Complications, subjective functional morbidity, and aesthetic outcomes were reviewed. A total of 35 MSLDFs and 40 LDMFs were performed: 24 MSLDFs (69%) and 25 LDMFs (63%) were inset into a previously irradiated field. There were 2 cases of infection requiring explantation in both MSLDF (8.3%) and LDMF (8.0%) radiated cohorts. There were no cases of donor-site seroma in the MSLDF cohorts versus 12 (30%) in the LDMF cohorts. Minor distal tip superficial epidermolysis was seen in 5 MSLDFs (14.3%), 3 of which were in the radiated cohort, and in 1 LDMF (2.5%) radiated cohort with no cases of flap loss. Functional and aesthetic outcomes were satisfactory. Four patients who had a unilateral MSLDF had a completion upper back lift. This is the largest series to date demonstrating the use of the MSLDF in both nonradiated and radiated patients and comparing it to a standard LDMF for breast reconstruction by the same surgeon. The pedicled MSLDF is a versatile option for breast reconstruction in radiated patients, and radiation should not be considered a contraindication for its use.

Immediate Skin Replacement Allows for Nipple-sparing, Direct-to-implant Reconstruction in Patients with Advanced Breast Cancers.

Summary:Mastectomy has evolved from approaches that involved extensive skin resection to nipple-sparing mastectomy (NSM). However, patients with advanced breast cancers who require extensive skin resection usually also have their nipple areola complexes (NACs) removed, even if they are distant from the cancer. Implant reconstruction in these patients is challenging as they require tissue expansion and, typically, radiotherapy with additional surgeries to complete their reconstruction. The aesthetic results of this approach are inferior to NSM and direct-to-implant reconstruction. In patients who require significant skin resection but whose NACs are free of tumor, we have found that immediate skin replacement using a muscle-sparing latissimus dorsi flap allows for NSM and direct-to-implant reconstruction, obviating the need for tissue expansion, delayed implant placement, and NAC reconstruction. Here, we report on 12 patients in whom this approach is utilized.

Combined Endoscopy-Assisted Muscle-Sparing Latissimus Dorsi Flap Harvesting with Lipofilling Enhancement as a New Volume Replacement Technique in Breast Reconstruction.

Introduction This study evaluated the feasibility and patient satisfaction of combined endoscopy-assisted muscle-sparing latissimus dorsi flap harvesting, with lipofilling enhancement for skin-preserving mastectomy. Methods This is a prospective study that included 21 female patients with small breasts (cup size A-B), subjected to skin-preserving mastectomy as a management of breast cancer. Combined endoscopy-assisted muscle-sparing latissimus dorsi flap harvesting with lipofilling enhancement was performed for immediate breast reconstruction. Patients were followed up for early and late postoperative complications including recurrence for at least 24 months. Postoperative patient satisfaction was assessed using the Kyungpook National University Hospital breast reconstruction satisfaction questionnaire. Results The study included 21 female patients with a mean age of 42.10 ± 8.46 years. Patients were followed up for 26.67 ± 3.38 months. The procedure was successful in all patients with a mean duration of 172.05 ± 28.22 minutes. Local recurrence was encountered in one patient (4.67%). Eighteen patients declared their satisfaction 6 months after the operation, while two patients were satisfied only after the second session of lipofilling. The overall postoperative patient satisfaction was 95.24%. The majority of the patients (93.3%) who underwent NSM surgery were satisfied, while only two-thirds (66.6%) of the patients who underwent SSM surgery were satisfied. Conclusions Combined endoscopy-assisted muscle-sparing latissimus dorsi flap harvesting with lipofilling enhancement seems to be a feasible and encouraging technique for the volume adjustment of small breasts, especially in nipple-sparing mastectomy. It leaves a minor back scar and has an acceptable rate of postoperative complications. The procedure showed high postoperative patient satisfaction.

Muscle sparing latissimus dorsi flap for reconstruction of a large chemo-necrosis of the chest wall: A case report

Extravasation of chemotherapeutic agents is a common complication in cancer centers. In severe cases involving large tissue necrosis, surgery may be needed to resect necrotic tissues and to cover the exposed areas. A 71 years old women was referred to our unit two month after extravasation of epirubicin from an implanted port-a-cath with a large chemonecrosis of the anterior chest wall. She presented an evolutive tissue necrosis extending from the upper anterior thoracic region to the right breast. Surgical debridements and negative wound pressure therapy were necessary in order to obtain clean areas. The final chest wall defect was covered using a Muscle Sparing Latissimus Dorsi pedicled flap. This surgical management have permitted a satisfying wound healing and functional recovery without any complication. Chemotherapeutics' extravasations can be a severe complication of oncologic treatment and have to be discussed between oncologists and plastic surgeons to find the most effective and suitable solution with consideration of the specificities of cancer therapy. In chest wall skin defect, the use of muscle sparing latissimus dorsi pedicled flap is a robust solution with low morbidity of the donor site.

Muscle-Sparing Latissimus Dorsi Flap in Breast Reconstruction: Experience from a Tertiary Care Center in a Developing Country

Evaluation of seromas in postmastectomy breast reconstruction: A retrospective observational study

BackgroundTo evaluate seroma complications, two techniques were carried out in breast reconstruction: conventional latissimus dorsi flap (CLD) and muscle-sparing latissimus dorsi flap (MSLD) after cancer-related mastectomy. MethodsA total of 108 postmastectomy procedures were performed with autologous tissue reconstruction with latissimus dorsi flaps (LDs) between January 2016 and May 2020. The patients were divided into two groups. The first group was reconstruction with the CLD, and the second group was reconstruction with the MSLD. Forty (40) patients in the first group and 68 patients in the second group were analyzed. Seroma formation was evaluated as the primary outcome. ResultsThe total number of seromas found in the donor area was 27, of which 45% (n = 18) were found with the CLD and 13.24% (n = 9) with the MSLD, with a difference of 31.76% in favor of the MSLD, with an 95% CI of 14–49 (p < 0.001). ConclusionsWe found a significantly lower incidence of seroma as a complication in patients who underwent MSLD breast reconstruction compared with those who underwent CLD breast reconstruction.

Outcome comparison between thoracodorsal artery perforator flap and muscle-sparing latissimus dorsi flap in axillary reconstruction after hidradenitis suppurativa excision.

Thoracodorsal artery perforator (TDAP) flap and muscle-sparing latissimus dorsi (MSLD) flap have been frequently used for axillary coverage after hidradenitis suppurativa (HS) excision. However, none showed superiority to others. This study compared both flaps to define the ideal option, highlighting flap outcomes and functional and aesthetic results. A retrospective study was conducted to compare both flaps that were used for axillary reconstruction in nine patients with bilateral HS Hurley stage III between 2017 and 2020. Eight TDAP and 10 MSLD flaps underwent functional evaluation using shoulder abduction angle (SA); the Disabilities of the Arm, Shoulder, and Hand (DASH) score; visual analog scale (VAS) for pain; and the Dermatology Life Quality Index (DLQI) questionnaires. Aesthetic assessment included the Scar Cosmesis Assessment and Rating (SCAR) scale and arm-chest interval. The mean operating time was 194.4 ± 51.58 and 128.5 ± 31.45 min for TDAP and MSLD (p =.009), respectively. Flap complications were significantly higher in the TDAP group (p =.034). There was no significant difference between both groups regarding SA; DASH, DLQI, VAS, and SCAR scale (p > .05). The mean arm-chest interval was significantly longer in the MSLD than in the TDAP group by 6.9 mm (p =.001). TDAP and MSLD are comparable versatile flaps to eradicate axillary HS with higher TDAP flap complications. Although the TDAP flap is less bulky than the MSLD flap, the MSLD flap shortens the harvesting time without a significant difference in functional outcomes and scar results.

Modified Incision for Muscle-sparing Latissimus Dorsi to Increase Flap Perfusion in the Morbidly Obese.

Summary:The muscle-sparing latissimus dorsi flap relies on perforators from the descending branch of the thoracodorsal artery. Previous descriptions placed a transverse skin island independent of perforator location, as any design was thought to capture enough perforators to ensure flap survival. We have found this approach prone to complications when attempting breast reconstruction in obese patients who require large flap volumes. Although the most proximal perforators have the most reliable blood flow, inclusion of these perforators reduces the arc of rotation, as the flap would be close to the pivot point at the most cranial point of muscle division, leaving significant volume in the axilla. Here we describe a modified skin incision that includes all of the proximal perforators but also allows us free design of the skin island to harvest those areas of the back with maximal subcutaneous tissue and with enough distance from the pivot point to optimize arc of rotation.
