Reevaluation of Recipient Vessel Selection in Breast Free Flap Reconstruction.

Current consensus has established the internal mammary vessels (IMV) over the thoracodorsal vessels (TDV) as the preferred recipients for microvascular breast reconstruction due to their superior flow rates and long-established outcomes. Yet, there are occurrences where the IMVs are not reliable and may subsequently prompt intraoperative decision-making. Several options exist, including the contralateral IMVs, thoracoacromial vessels, and TDVs. The appropriate sequence for vessel choice is not universally agreed upon. This study reevaluates the TDVs to highlight their viability as a second-line intraoperative alternative to the IMV and provide reference to the straightforward dissection required for harvest. A retrospective, single-institution, breast-level analysis examining 4754 breast free flaps from 2978 patients undergoing bilateral free flap reconstruction was conducted. Postoperative complications within 180 days were evaluated, and cohorts based on anatomic anastomosis (IMV vs. TDV) were created to compare outcomes. Subanalysis was conducted based on flap laterality as well as whether a flap was planned or converted intraoperatively. Of 4754 breast free flaps, 4269 (89.8%) used the IMV while 485 (10.2%) used the TDV. Most complication rates between the TVD and IMV were not significantly different. Rates of flap loss were 1.0% and 1.2% for the IMV and TDV anastomosis (p = 0.59). IMV and TDV anastomosed flaps experienced similar rates of fat necrosis (6.3% vs. 6.2%, p = 0.915). However, multivariable analysis of all breasts regardless of laterality showed that skin necrosis was significantly less likely in TDV breasts (OR 0.45, 95% CI 0.29-0.71, p < 0.001). Given the relative similarity in cohort outcomes, TDV anastomosis can be considered a viable alternative to the IMV when the IMV is unavailable or technically disadvantageous. The TDV artery remains a robust and reliable option in the present-day plastic surgeon's repertoire for breast reconstruction.

The posterior approach to the thoracodorsal vessels for microsurgical free tissue transfer

The latissimus dorsi (LD) muscle is a workhorse flap in reconstructive surgery (e.g., breast reconstruction, chest wall defects, and lower limb trauma). The thoracodorsal artery and its venae comitantes supply this muscle. Recipient vessel options for microsurgical free flap reconstruction of the posterior thorax and lower back are limited. The thoracodorsal vessels are an excellent option due to their reliable anatomy and ease of access. In circumstances when the patient is best positioned prone, the posterior approach to access the thoracodorsal vessels is advantageous. We describe the technique to identify and isolate these vessels via a posterior approach.

Use of the Intercostal Artery-based Latissimus Dorsi Muscle for Intrathoracic Reconstruction after Division of the Thoracodorsal Vessels and Latissimus Dorsi Muscle.

The latissimus dorsi muscle is the workhorse flap for intrathoracic reconstruction. Prior thoracotomy, which divides the latissimus dorsi muscle, limits the muscle's intrathoracic reach. We present our experience using the distal portion of the muscle for intrathoracic reconstruction based off an intercostal vessel. We also demonstrate the ability of this intercostal perforator to allow for chimeric flap elevation with a separate skin paddle, depending on the branching pattern of the intercostal vessels. This study provides a case series of three consecutive patients, treated between September 2021 and June 2022. The intrathoracic pathology addressed in these patients are bronchopleural fistula, aortoesophageal fistula, and bronchoesophageal fistula. All patients had the resolution of symptoms related to intrathoracic fistulae and did not experience recurrence. This novel pedicled muscle flap can be an additional option for patients with prior thoracotomy and avoids the morbidity which can be seen with the serratus or rectus abdominis muscle flaps.

The conjoined latissimus dorsi and parascapular free flap for reconstruction of extensive soft tissue defects

Durable and resilient soft tissue reconstruction of vast defects of the extremities or the torso. Reconstruction of disproportionately large defects, particularly in cases of simultaneous bone and joint reconstruction. History of surgery or irradiation of upper back and axilla, impossibility of surgery under lateral positioning; relative contraindications in wheelchair users, hemiplegics, or amputees. General anesthesia and lateral positioning. First, the parascapular flap is harvested, with the initial skin incision made medially in order to identify the medial triangular space and the circumflex scapular artery. Flap raising then proceeds from caudal to cranial. Second, the latissimus dorsi is harvested, with the lateral border being dissected free first, before the thoracodorsal vessels are visualized on its undersurface. Flap raising then proceeds from caudal to cranial. Third, the parascapular flap is advanced through the medial triangular space. If the circumflex scapular and thoracodorsal vessels originate separately from the subscapular axis, an in-flap anastomosis is warranted. Subsequent microvascular anastomoses should be performed outside the zone of injury, typically in an end-to-end fashion of the vein and end-to-side fashion of the artery. Postoperative anticoagulation with low-molecular-weight heparin under anti-Xa monitoring (semitherapeutic in normal-risk and therapeutic in high-risk cases). Hourly clinical assessment of flap perfusion for 5consecutive days, followed by stepwise relaxation of immobilization and commencement of dangling procedures in cases of lower extremity reconstruction. Between 2013 and 2018, 74conjoined latissimus dorsi and parascapular flaps were transplanted to cover vast defects of the lower (n = 66) and upper extremity (n = 8). The mean defect size was 723 ± 482 cm2 and the mean flap size was 635 ± 203 cm2. Eight flaps required in-flap anastomoses for separate vascular origins. There was no case of total flap loss.

A Systematic Review and Meta-analysis of Clinical Outcomes in Autologous Breast Reconstruction Using Internal Mammary Artery Perforators as Recipient Vessels.

The protocol has been previously published in PROSPERO (CRD42020190020). The PubMed, Scopus, Web of Science, and PROSPERO databases were searched. Two independent reviewers evaluated the articles for inclusion in the study. Study quality was assessed using the Newcastle-Ottawa Scale and the MINORS instrument (Methodological Index for Non-Randomized Studies). Of the 361 articles screened, 13 studies were included (313 patients with 318 flaps; 223 unilateral, 31 bilateral, mean average age 51.2 and mean BMI 27.8 ± 1.9). The mean overall success rate was 99.8%, the pooled surgical success rate was 100% [95% confidence interval (CI): 97%-100%], and the overall rate of complications was 11% (95% CI: 7%-18%). The most common complication was vascular-related to microanastomoses, with an incidence of 5% (95% CI: 2%-10%). The fat necrosis rate was 3% (95% CI: 2%-6%). This study verified that internal mammary artery perforator vessels are reliable in breast reconstruction, with a high success rate and a relatively low complication rate. Moreover, in selected microsurgical breast reconstruction patients, internal mammary artery perforators may be the primary recipient vessel choice over the internal mammary artery or thoracodorsal vessels.

Techniques of inserting deep inferior epigastric perforator flap obliquely in immediate breast reconstruction after total mastectomy

This study aimed to share the experience of inserting a deep inferior epigastric perforator (D.I.E.P) flap obliquely in immediate breast reconstruction after total mastectomy. Forty patients underwent immediate breast reconstruction with flap D.I.E.P after total mastectomy. The flaps were placed obliquely, with the upper edge facing downward and inward. After being placed in the recipient region, parts of the flap at both ends were removed, the upper end was fixed into the II-III intercostal space next to the sternum, and the lower end was folded to create a projection of the lateral lower pole of the breast. The flap pedicle was anastomosed to the thoracodorsal vessels (TDVs) if the contralateral flap pedicle was used; conversely, the mammary vessels (IMVs) were used. Satisfaction with breast shape was assessed after 6 months using the BREAST-Q questionnaire. A total of 37/40 flaps were well vascularized; 36/37 patients with a survival flap were interviewed, showing that the average BREAST-Q evaluation score of satisfaction with breast shape was 62.22 (51-78). The number of answers for satisfied and very satisfied with breast shape accounted for 94.44%. Inserting the D.I.E.P flap obliquely has the advantage of being easy to shape the breast contour, creating a moderate projection and symmetry to the opposite breast. The author suggested using the IMVs as the receiving vessels when using the pedicle of the flap on the ipsilateral side and the TDVs when the contralateral pedicle flap was used.

Preliminary experience of autologous free myocutaneous flap combined with free dermal graft in the treatment of refractory empyema with bronchopleural fistula

ObjectivesTo explore the effects of autologous free dermal graft combined with free myocutaneous flap on bronchopleural fistula (BPF) with empyema, we summarized and analyzed two cases. MethodsTwo patients with refractory empyema and BPF were treated with autologous free dermal graft combined with free myocutaneous flap. The treatment included debridement of empyema, rib resection drainage, repair of bronchopleural fistula, and free vastus lateralis myocutaneous flap transplantation to eliminate the empyema. After the free dermal graft was harvested from the healthy skin around the incision, it was inserted into the fistula and sutured with the surrounding pleural tissue. The keys to the operation lies in the anastomosis of the lateral circumflex femoral artery (LCFA), vein and nerve that supply the vastus lateralis muscle flap to the thoracodorsal vessels and nerves. After surgery, the empyema, air leakage, and the survival of the myocutaneous flap were observed. ResultsThere was no disease recurrence after follow-up for seven and six months, respectively. Re-examination of the chest computed tomography (CT) or magnetic resonance imaging (MRI) indicated that the abscess cavity had disappeared. No necrosis of the myocutaneous flap was observed after surgery. ConclusionThe application of autologous free dermal graft combined with free vastus lateralis myocutaneous flap transplantation is effective in the treatment of patients with bronchopleural fistula with refractory chronic empyema, and the clinical effect is satisfactory.

Application of anterior serratus branch of thoracodorsal vessel in repairing chest wall defect

To investigate the application of anterior serratus branch of thoracodorsal vessel in repairing chest wall defect. Between October 2018 and March 2021, bilateral free lower abdominal flaps were used to repair large-area complex defects after chest wall tumor surgery in 23 patients. The patients were all female; the age ranged from 23 to 71 years, with an average age of 48.5 years. There were 11 cases of locally advanced breast cancer, 4 cases of phyllodes cell sarcoma, 3 cases of soft tissue sarcoma, 3 cases of recurrence of breast cancer, and 2 case of osteoradionecrosis. The size of secondary chest wall defect after tumor resection and wound debridement ranged from 20 cm×10 cm to 38 cm×14 cm, the size of flap ranged from 25 cm×12 cm to 38 cm×15 cm, the length of vascular pedicle was 9-12 cm (mean, 11.4 cm). Fourteen cases of simple soft tissue defects were repaired by flap transplantation; 5 cases of rib defects (<3 ribs) and soft tissue defects were repaired by simple mesh combined with flap transplantation; and 4 cases of full-thickness chest wall defect with large-scale rib defect (>3 ribs) were repaired by "mesh plus bone cement" rigid internal fixation combined with flap transplantation. The anterior serratus branch of thoracodorsal vessel was selected as the recipient vessel in all cases, the revascularization methods include 3 types: the proximal end of the anterior serratus branch plus other recipient vessels (13 cases), proximal and distal ends of anterior serratus branch (6 cases), and proximal ends of two anterior serratus branches (4 cases). The main trunk of thoracodorsal vessels was preserved completely in 23 patients. All patients were followed up 10-18 months, with an average of 13.9 months. After operation, the flap survived completely, the shape of reconstructed chest wall was good, the texture was satisfactory, and there was no flap contracture deformation. There was only a linear scar left in the flap donor site, and the abdominal wall function was not significantly affected. There was no tumor recurrence during follow-up. The anterior serratus branch of thoracodorsal vessel has a constant anatomy and causes little damage to the recipient site, so it can provide reliable blood supply for free flap transplantation.

Treatment of skin cancer arising within a burn scar (case report)

Background. In 1–2 % of cases, burn scars can cause more aggressive skin cancer that has a worse prognosis than conventional skin cancer. Most burn scar carcinomas are the squamous cell type (88 %) with the frequency of metastasis of 27 %. Due to the rarity of this malignancy and absence of guidance, treatment of scar carcinoma continues to be controversial. Surgical excision remains a standard mode of treatment for squamous cell carcinoma of the skin. Surgery is associated with problems to define a required limit to achieve clear margins; and subsequent grafting of the postoperative defect is limited due to the rigidity of the surrounding tissue and microcirculatory defects.Case description. We present a case report of squamous cell carcinoma of the skin originating from burn scars. The patient received a radical course of conformal external beam therapy with a total dose of of 68 Gy in 2 Gy single doses (34 fractions) resulting in an increase in the ulcer due to the destruction of the infiltrative component of the tumor. Radical electrosurgical excision of the tumor with a free TRAM-flap reconstruction in the MS-0 version (using the full width of the rectus abdominis muscle) was performed. Microvascular anastomoses were made between the deep lower epigastric and thoracodorsal vessels on the right. There were no postoperative complications. No evidence of recurrence and tumor progression was found with a follow-up for 7 months.Conclusion. A personified approach to the treatment of burn scar carcinoma demonstrated good treatment outcomes. Surgical reconstruction of the postoperative defect in these patients may require the use of composite flaps and, in specific cases, microsurgical techniques.

Reconstruction of Axillary Defect due to Necrotizing Fasciitis and Debridement Using a Free-Flap Transfer: A Report of Three Cases

Abstract Background Necrotizing fasciitis is a well-known disease that causes extensive tissue infection and requires radical debridement of the infected tissue. It can occur in all parts of the body, but there are few reports of necrotizing fasciitis in the axilla. We treated three patients with axillary necrotizing fasciitis. Methods In all cases, patients were referred to us after radical debridement of the infected soft tissue in the emergency department. At the first visit to our department, there were fist-sized soft tissue defects in the axilla. Moreover, the ipsilateral pectoralis major and latissimus dorsi muscles were partially resected because of the debridement of necrotizing fasciitis. In all cases, the ipsilateral thoracodorsal vessels were severely damaged and free-flap transfer was performed to close the axillary wound. Results All free flaps survived without complications. The patient's range of motion for shoulder abduction on the affected side was maintained postoperatively. Conclusion If necrotizing fasciitis occurs in the axilla, tissue infection can spread beyond it. In such a case, free-flap transfer can be an optimal treatment. Radical resection of the infected tissue results in the absence of recipient vessels in the axilla. Surgeons should bear in mind that, because of radical resection of the infected tissue, they may need to seek recipient vessels for free-flap transfer far from the axilla.

Advantages and disadvantages of using the internal thoracic artery perforators as recipient vessels in autologous breast reconstruction—a narrative review

: The rates of breast reconstruction after mastectomy are rising each year. Autologous breast reconstruction using free tissue transfer is considered the gold standard reconstruction, especially with recent controversy surrounding breast implant-associated anaplastic large cell lymphoma (BIA-ALCL). During free tissue transfer, the flap vessels must be anastomosed to recipient vessels on the chest wall. There are multiple options of recipient vessels during microvascular breast reconstruction. Most commonly, the thoracodorsal vessels or the internal thoracic vessels [also known as the internal mammary (IM) vessels] are used as the recipient vessels for microvascular anastomosis of the free tissue transfer. Other second-line options include the thoracoacromial axis and the lateral thoracic vessels. The use of perforators of the internal thoracic vessels for free flap anastomosis during autologous breast reconstruction has been in use for almost twenty years. They are generally favoured over use of thoracodorsal vessels as they result in medialisation of the flap. In recent years, the use of perforators of the internal thoracic vessels has become popular. Great debate surrounds whether or not they should be used as recipient vessels as opposed to the conventional main vessels. In this article, we discuss the advantages and disadvantages of both techniques to guide the choice of reconstructive microsurgeons.

Free vastus lateralis muscle flap transplantation for postoperative chronic empyema: retrospective analysis of eight case series.

Postoperative chronic empyema (PPE) remains a complex challenge for thoracic surgeons. We retrospectively investigated patients with PPE who were treated with free vastus lateralis muscle flap transplantation, and report our results. Eight patients with PPE and persistent bronchopleural fistula (BPF) treated in our hospital from January 2015 to June 2019 were retrospectively analyzed, the time since onset of empyema ranged from 5 to 72 months. The operation was performed in two stages, stage I surgery included empyema debridement, rib resection drainage or open-window thoracostomy (OWT), meanwhile, BPF was treated under bronchoscope. Stage II surgery included obliteration of the pleural space by free muscle flap transplantation. The keys to the operation are thorough debridement, closure of the BPF, and complete obliteration of the residual pleural space. The challenge lies in the anastomosis of the lateral femoral circumflex artery and vein that supply the vastus lateralis muscle flap to the thoracodorsal vessels. The free muscle flaps survived in all eight patients. The abscess cavity was completely obliterated with the muscle flap. Good efficacy was achieved with primary wound healing. No serious perioperative complications were reported. No empyema recurrence, atrophy, infection, or necrosis of the muscle flap was seen during the 18- to 72-month follow-up. The vastus lateralis muscle flap has a large volume with good blood supply and strong antibacterial ability. It can be used for effective obliteration of a large residual cavity caused by empyema and maintains a good thoracic shape. It is an ideal choice for the treatment of postoperative chronic refractory empyema.

Necrosis or Flap Loss After Deep Inferior Epigastric Perforator Reconstruction: Impact of Perforators and Recipient Vessels

AbstractBackground The aim of this study is to analyze the impact of the number and location of perforators harvested and the recipient vessels used on deep inferior epigastric perforator (DIEP) flap survival and the occurrence of flap necrosis requiring re-operation.Patients and Methods Four hundred and seventy-one DIEP flap reconstructions, performed between January 2008 and December 2019, were retrospectively analyzed.Results Flap necrosis requiring re-operation was observed in 40 (9%) of flaps and total flap loss rate was 1% (n = 6). No significant differences were observed between internal mammary vessels (IMV, n = 287, 61%) and thoracodorsal vessels (TDV, n = 184, 39%) regarding postoperative re-anastomosis (p = 0.529) or flap survival (p = 0.646). Intraoperative conversion from IMV to TDV was performed on 64 (14%) patients. TDV were more commonly associated with problems in preparation of the vessels than IMV (p &lt; 0.001). Second vein anastomosis was performed on 18 (4%) patients. In total, 81 flaps (17%) had one perforator, 165 (35%) had two, 218 (46%) had three to five, and 7 (2%) had more than five perforators. Flaps with three to five perforators were more commonly associated with flap necrosis (p &lt; 0.001) than flaps with one or two perforators. Independent factors associated with necrosis were body mass index (BMI) &gt; 30 (odds ratio [OR]: 2.28; 95% confidence interval: 1.06–4.91, p = 0.035) and perforator/s located on the lateral row (OR: 3.08, 95% CI 1.29–7.33, p = 0.011).Conclusion We conclude that the occurrence of flap necrosis requiring re-operation may be higher in DIEP flaps with more than two perforators or perforator/s located on the lateral row and in obese patients. Neither the recipient vessels used nor the number of perforators harvested had any impact on the flap survival rate.

Safety of Coupled Arterial Anastomosis in Autologous Breast Reconstruction.

This study compares the outcomes of coupled versus hand-sewn arterial anastomosis in microvascular breast reconstruction. Retrospective chart review of breast reconstruction free flaps performed between 2013 and 2018 was conducted. Primary end points included flap loss, intraoperative arterial anastomosis revision, and operating room takeback. The decision to couple the arterial anastomosis was based on patient's age, surgeon's preference, history of radiation, and vessel quality. All anastomoses were performed under ×3.5 loupe magnification to internal mammary or thoracodorsal vessels. Authors reviewed 104 free flaps; two were lost in hand-sewn group; no flaps were lost in coupled group. There was no significant difference in anastomotic revision rate between coupled and hand-sewn arterial anastomosis (p = 0.186) or return to operating room (OR) between coupled and hand-sewn flaps (p = 1.000). Reasons for takeback included venous congestion and hematoma. This study reflects that coupled arterial anastomosis in breast reconstruction may be safely performed without increased risk in anastomotic revision, takeback, or flap loss. Decision to couple should be based on surgeon skill, patient age and history, and assessment of flap and recipient site vasculature.

Shaping of the abdominal flap in breast reconstruction: The coning technique in muscle sparing TRAM

In the setting of autologous breast reconstruction, achieving an aesthetic outcome through shaping of the flap is of the upmost importance. We describe the abdominal flap folding technique of ‘coning’ and the indications. We define ‘coning’ as the technique of folding the abdominal flap in a circular fashion to create a conical breast mound, with the line of fusion forming a pillar of tissue for structural integrity. A retrospective study of 34 patients undergoing unilateral muscle-sparing TRAM flap was performed. Of these patients, the majority (79.4%) underwent immediate reconstruction, with the thoracodorsal vessels largely acting as the recipients (94.1%). Three (8.8%) patients were noted to have a contour defect secondary to incomplete folding of the flap. Two (5.9%) patients had partial skin envelope necrosis. One patient had 50% flap loss, requiring return to theatre for excision. In conclusion, coning was used exclusively in the muscle-sparing TRAM flap. This cuff of muscle protected the pedicle during folding through cushioning the perforators at their most vulnerable points. This technique allowed for muscle cuff harvest whilst minimising anterior sheath sacrifice. Coning achieved long-term maintenance of shape, volume and projection.

Arm reconstruction

The arm is less often concerned by reconstructive surgeries than more distal parts of the upper extremity. However, when affected, the arm is frequently part of complex mutilating injuries involving composite defects. For a given traumatic or oncologic defect, there are several reconstructive options and choosing the right sequence may pose a challenge even to the most experienced surgeon. The latter must integrate not only functional and esthetic requirements, but also the surgeon's habits, especially in situations of emergency. Once life-threatening conditions are averted, wound debridement, bony stabilization, neurovascular, and cutaneous reconstruction tailored to the defects should be performed in a single-stage procedure. Functionally, prompt bony stabilization is necessary to allow early mobilization. Diaphyseal shortening of the humerus can be a salvage procedure to avoid nerve and vascular grafting, with good biomechanical tolerance up to 5cm. Restoration of adequate elbow motion sometimes requires muscle transfer and should be a main concern, as proper positioning of the hand during daily activities demands a functional elbow joint. Esthetically, the surgeon must choose the most cosmetic skin coverage option whilst limiting morbidity of the donor site area. The flaps vascularized by the sub- scapular or thoraco-dorsal vessels are the most useful flaps for arm reconstruction. This paper discusses the reconstructive sequence of complex defects of the arm and provides a review of commonly used reconstructive techniques supported with illustrative cases.

Diametric Comparison between the Thoracodorsal Vessel and Deep Inferior Epigastric Vessel in Breast Reconstruction

Background In microvascular anastomosis, size discrepancy is common and can increase thrombotic complications. If size differences can be predicted, then vessels of the appropriate size can be selected. This study documented the difference in diameter between the thoracodorsal (TD) vessel and deep inferior epigastric perforator (DIEP) pedicle in each patient who underwent breast reconstruction using free tissue transfer. Patients and Methods. This retrospective study included 32 anastomoses (27 breasts including five cases of supercharged anastomosis) of breast reconstruction with the free DIEP flap and TD recipient between August 2018 and June 2019. In the microscopic view, the caliber of the TD vessel, the largest branch to the serratus anterior muscle, the descending branch, the largest and the second largest branches to the latissimus dorsi muscle, and the DIEP pedicle were measured. Results The diameter of the deep inferior epigastric artery was similar to that of the descending branch, and their anastomosing rate was 56.3%. The diameter of the deep inferior epigastric vein was similar to the branch to the serratus anterior muscle and the descending branch, and their anastomosing rates were 29.3% and 29.3%, respectively. All flaps were survived; however, in one case, a reoperation was needed to remove the hematoma, in which case fat necrosis occurred as the only complication. Conclusion TD branches of similar size to the DIEP pedicle were prioritized in anastomosis. The descending branch and the branch to the serratus anterior muscle are expected to be good candidates as recipients in breast reconstruction with DIEP free flap. Moreover, supercharged anastomosis of DIEP pedicles can be achieved within TD branches.

Unilateral autologous breast reconstruction with unipedicled and bipedicled deep inferior epigastric artery perforator flap: A review of 168 cases over 3 years

Harvesting a DIEP flap based on bipedicled perforators can enhance vascular perfusion, which can reduce complication rates, minimize fat necrosis, and flap failure. This study summarizes our experience with using unipedicled and bipedicled DIEP flaps for breast reconstruction. A total of 168 consecutive patients undergoing unilateral breast reconstruction with DIEP flaps over a 3-year period were retrospectively reviewed. Primary microvascular anastomoses were performed to the thoracodorsal vessels in both unipedicled and bipedicled DIEP groups. In bipedicled DIEP flap cases, additional secondary microvascular anastomoses were performed either by extraflap or intraflap options. Clinical characteristics and outcomes were recorded. Unipedicled (n = 89; 53%) and bipedicled flaps were used. Both groups were comparable for mean age, diabetes mellitus, hypertension, smoking, and chemotherapy. BMI was 24.9 ± 3.6 in the unipedicled group and 22.8 ± 2.9 in the bipedicled group (p < .001). The surgical duration was longer in bipedicled group (367 ± 86.5 minu vs 403.7 ± 65.6 min, p < .05) but incidence of fat necrosis decreased in the bipedicle group (24 patients [27%] vs. 7 patients [8.9%] p < .05). There was no flap loss or instance of abdominal hernia in any group. The bipedicled DIEP flaps may be a feasible option for large breast reconstruction in thin patients. However, the additional microsurgical technical complexity and longer operative time must be considered.

Re-augmentation of the Axilla Using a Turn-Over Flap - a New Approach for the Surgical Treatment of Secondary Lymphedema After Breast Cancer.

Introduction Scarring and volume reduction of the axillary space resulting in persistent lymphedema is a side effect of axillary treatment in breast cancer patients. The aim of this paper is to describe the reduction of lymphedema achieved with a turnover flap. Materials and Methods Between October 2016 and May 2018, five patients with grade 2 lymphedema following breast cancer therapy underwent reconstructive surgery with a turnover flap. Complete excision of the symptomatic axillary scar tissue followed by re-augmentation using a turnover flap was performed. Subsequently, all patients underwent breast reconstruction using a distant flap reconnected to the thoracodorsal vessels. The circumference of both arms, quality of life and pain were measured before and after surgery. Results An average reduction in pain in the ipsilateral arm from 6 to 1 on the numerical scale as well as an improvement in quality of life (2.8 vs. 7.0) was observed. A decrease in lymphedema especially in the upper arm was identified. No complications such as secondary bleeding, infections or flap loss were observed. Conclusion Complete removal of the axillary scar tissue after breast cancer treatment and re-augmentation of the axilla with a turnover flap results in a reduction in ipsilateral lymphedema and an improvement in pain and quality of life. We interpret these findings as a result of the physiological re-alignment of the lymphatic vessels combined with a lymph node-containing local transposition flap. Therefore, re-augmentation with a turnover flap could be an effective non-microsurgical alternative to lymph node transplantation.

Synchronous Sentinel Node Biopsy in Autologous Breast Reconstruction in Node Negative Axilla

Background: National Institute of Clinical Excellence guidelines recommends that all eligible patients with breast cancer who needs mastectomy should be offered immediate breast reconstruction. In Implant based reconstruction sentinel node biopsy (SLNB) is performed at the time of mastectomy in clinically node negative axilla but in autologous free flap reconstruction SLNB is routinely performed upfront. This helps to determine the sentinel node biopsy status prior to autologous reconstruction and allows the surgeons to perform axillary node clearance safely without any threat to the anastomosis when free flaps are anastomosed to thoracodorsal (TD) vessels in axilla. With a trend towards de escalation of axillary surgery in appropriate cases and the increasing use of Internal mammary Vessels (IMV) for vascular anastomosis we proposed that the impact of performing sentinel node biopsy synchronously with mastectomy and immediate DIEP reconstruction will be minimal.
