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.

Clinical Study on the Thoracodorsal Artery Perforator Flap in Breast-Conserving Reconstruction of T2 Breast Cancer.

BACKGROUND: Breast-conserving surgery combined with oncoplastic breast surgery has become the standard surgical treatment for early breast cancer. OBJECTIVE: The purpose of this study was to investigate the safety and efficacy of the thoracodorsal artery perforator flap (TDAPF) in breast-conserving reconstruction of T2 breast cancer. METHODS: Thirty patients with T2 breast cancer admitted to our hospital from January 2019 to December 2020 were enrolled to receive pedicled TDAPF for repairing breast defects after breast-conserving surgery. Intraoperative conditions, postoperative complications, and shape satisfaction after breast reconstruction were recorded. RESULTS: The operation was successfully completed in all 30 patients, with an operation time of 177.77 ± 24.39 min, bleeding of 44.17 ± 7.67 mL, and length of hospital stay of 5.23 ± .97 d. There was no deformity or seroma at the donor site. Breast shape recovered well after operation. After operation, one patient had fat liquefaction in the recipient site, which healed well after wound treatment. The incidence of postoperative complications was 3.33%. Postoperative follow-up lasted 16-28 months, with a median of 22 months. The Breast-Q score for breast satisfaction was 61.83 ± 12.87 at 6 months after operation, compared to 62.07 ± 11.78 before operation (P > .05). CONCLUSIONS: TDAPF, featuring a high survival rate, moderate flap area, fewer postoperative complications, and high satisfaction with breast shape after operation. For east asian women with moderate breast size, TDAPF is a safe, effective choice for repairing defects in breast-conserving surgery for T2 breast cancer.

Systematic review of the free thoracodorsal artery perforator flap for head and neck reconstruction.

BACKGROUND: The thoracodorsal artery perforator (TDAP) flap has gained interest as a option for reconstruction of head and neck defects while minimizing donor site morbidity as compared to traditional workhorse flaps. The primary aim of this systematic review is to assess the postoperative outcomes and efficacy of this flap. METHODS: Several databases were screened for relevant citations. The quality of studies and risk of bias were evaluated using the MINORS scoring system. RESULTS: Twenty articles containing 168 patients undergoing at least one TDAP flap reconstruction met the inclusion criteria. There were no incidences of total flap failure and only 10 incidences of partial flap failure (5.95 %). Flap complications and donor site morbidity was low. The average MINORS score of the studies suggested a moderately high amount of bias. CONCLUSIONS: Based on limited quality evidence, this review suggests that TDAP flap is a safe and feasible option for head and neck reconstruction with comparable success rates as other commonly used flaps, with low complication rate and donor site morbidity. Further large-scale studies are warranted.

Free Thoracodorsal Artery Perforator Flap for Head and Neck Reconstruction: An Indian Experience.

Background We describe our experience with use of free thoracodorsal artery perforator (TDAP) flap for head and neck (H&N) cancer reconstruction, with respect to the patient and disease profile, suitable defect characteristics, the reconstructive technique, and complications. Methods Consecutive patients ( N = 26) undergoing free TDAP flap for H&N onco-reconstruction, in a single center, were included from January 2015 to December 2018 and the data were analyzed. Results Perforator(s) were reliably predicted preoperatively, using handheld Doppler. Lateral position was comfortable for the harvest. Twenty flaps were harvested on a single perforator, more commonly musculocutaneous ( n = 16). The thoracodorsal nerve and latissimus dorsi muscle could be preserved, completely in almost all cases. The skin paddle was horizontally ( n = 5) or vertically ( n = 21) oriented, both giving a satisfactory scar. The flap was used as a single island or two islands by de-epithelializing intervening skin. Pedicle length was sufficient in all cases. Four cases were explored for suspected venous insufficiency. Two had thrombosis, of which one was salvaged, while the other necrosed. One flap had minimal partial necrosis, which was managed with secondary suturing. The 5-year follow-up showed good oral competence, mouth opening, and cosmetic satisfaction among patients. Conclusion TDAP flap provides all the advantages of a perforator-based free flap and of back as a donor site with close color match to the face, relatively hairless, and thickness in between the thigh and the forearm. It can be a useful tool to provide an ideal functional and aesthetic outcome, with a hidden donor site and minimal donor site morbidity in selected cases.

The versatile thoracodorsal artery perforator flap for extremity reconstruction: from simple to five types of advanced applications and clinical outcomes.

BACKGROUND: Application of the thoracodorsal artery perforator (TDAP) flap is known to be a popular and reliable method for extremity reconstruction. This manuscript presents our clinical outcomes in reconstructing soft tissue defects using simple and advanced TDAP flaps. METHODS: From 2013 to 2022, 53 patients with a mean age of 23 years (ranging from 2 to 72 years) underwent reconstructive surgery with different patterns of free TDAP flaps, including chimeric TDAP flaps, double skin paddle TDAP flaps, flow-through TDAP flaps, conjoined TDAP flaps, and microdissected debulking TDAP flaps. RESULTS: All TDAP flaps survived. The size of the TDAP skin paddle ranged between 5 × 3 and 25 × 10 cm2. Primary closure of the donor site was achieved in all patients in the simple application group, and one patient in the advanced application group underwent partial skin grafting. Partial flap loss occurred in one case in the simple TDAP flap group and four cases in the advanced application group. There was one case of flap bulkiness and two cases of scar hyperplasia in the simple TDAP flap group. The mean follow-up duration was 11 months (4-46 months). CONCLUSIONS: The free TDAP flap, with five types of advanced applications, makes it versatile for reconstructing different kinds of soft tissue defects of the extremities that can be used to achieve individualized defect reconstruction, minimize donor site morbidities, and an aesthetic appearance.

Individualized design of thoracodorsal artery perforator chimeric flap for customized reconstruction of complex three-dimensional defects in the extremities.

BACKGROUND: It was always challenging to accurately and effectively reconstruct the complicated defects with three-dimensional tissue deficits in the extremities. Muscle-chimeric perforator flap is an excellent choice for repairing those complicated wound. However, problems like donor-site morbidity and time-consuming intramuscular dissection still exist. This purpose of this study was to present a novel design of the thoracodorsal artery perforator (TDAP) chimeric flap for the customized reconstruction of complex three-dimensional tissue defects in the extremities. METHODS: From January 2012 to June 2020, 17 patients with complex three-dimensional deficits in the extremities were retrospectively analyzed. All patients in this series underwent extremity reconstruction using latissimus dorsi (LD)-chimeric TDAP flap. Three different types of LD-chimeric TDAP flaps were performed. RESULTS: A total of seventeen TDAP chimeric flaps were successfully harvested for the reconstruction of those complex three-dimensional defects in extremities. Among them, Design Type A flaps were used in 6 cases, Design Type B flaps were performed in 7 cases, and Design Type C flaps were used in the remaining 4 cases. The sizes of the skin paddles ranged from 6 cm × 3 cm to 24 cm × 11 cm. Meanwhile, the sizes of the muscle segments ranged from 3 cm × 4 cm to 33 cm × 4 cm. All the flaps survived. Nevertheless, one case required re-exploration owing to venous congestion. Moreover, the primary closure of the donor site was successfully achieved in all patients, and the mean follow-up time was 15.8 months. Most of the cases displayed satisfactory contour. CONCLUSION: The LD-chimeric TDAP flap is available for the reconstruction of complicated defects with three-dimensional tissue deficits in the extremities. It provided a flexible design for customized coverage of complex soft tissue defects with limited donor site morbidity.

Application of Three Different Types of Pedicled Latissimus Dorsi Flaps in Repairing Nearby Deep Soft Tissue Defects: Cosmetic Result and Shoulder Functionality Evaluation in One Center.

Objective: The latissimus dorsi (LD) flap has generally been considered a workhorse flap in clinics. However, the impairment of shoulder function and the dramatic appearance in the donor site are the major problems associated with traditional latissimus dorsi myocutaneous flap (LDMF). Here, we analyzed the reliability of three types of LD flaps in repairing deep soft tissue defects in the upper limbs, shoulder, back, and chest wall. Methods: From December 2016 to December 2020, 21 patients from our center underwent reconstruction of deep soft tissue defects using different types of LD flaps. The distribution of the thoracodorsal artery and the location of its branches were confirmed by imaging examination. Based on the defects, traditional LDMF, thoracodorsal artery perforator flap with capillary perforators (TAPcp), or low-skin-paddle pedicled LDMF was selected and specifically designed for each patient. The appearance satisfaction and shoulder functional of daily life recovery were evaluated. Results: A total of 12 traditional LDMF, 4 TAPcp, and 5 low-skin-paddle pedicled LDMFs were used. All flaps survived well. The donor site was sutured directly with satisfactory appearance (n = 7) or repaired using skin grafts (n = 14). Compared to traditional LDMF, TAPcp and low-skin-paddle pedicled LDMF have faster shoulder function of daily life recovery. Conclusion: Based on the characteristics of defects, personalized design of different types of LD flaps is a reliable option to repair different defects.

Cubital fossa defect- our reconstructive experience with pedicle flaps.

Introduction: Cubital fossa wounds can be complicated by the non-availability of reliable, well-vascularized donor tissue. Closure with pliable and readily available donor tissue for cubital defect and early mobilization of the elbow joint is essential for better results. The authors did this study to see how best the results of cubital fossa defect cover can be achieved by pedicle flaps in a single stage without compromising the donor areas. Material and method: Patients having deep elbow wounds in which vital structures were lying exposed in the cubital region were included in this study. The patients were assessed for the availability of tissue for cover, reliability of flaps, flap pliability, the functional outcome of the elbow and donor site morbidity. Results: A total of 17 cases of cubital region defects are presented wherein closure of the wound by means of primary closure was not possible. Out of these, eight were covered with Pedicled Thoracodorsal Artery Perforator (TDAP) flaps, five with Pedicled split Latissimus Dorsi Muscle (SLDM) flaps and four with reversed lateral arm flaps (RLA). Post-operatively all the flaps were healthy, patients attained a good range of elbow joint movements with no clinically evident morbidity of the donor site. Conclusion: Cubital fossa defect coverage needs dedicated planning to obtain a sturdy tissue for cover. In the presence of local tissue damage or scarring, we have looked elsewhere to bring pliable and well-vascularized tissue which is reliable. The flaps we used have allowed single-stage reconstruction and early mobilization of the elbow joint with good functional recovery.

Multiple free dorsal flaps for symmetrical peripheral gangrene of the extremities: A case report.

We present a case of symmetrical peripheral gangrene of the extremities due to acute infectious purpura fulminans that was reconstructed with four free flaps harvested from the bilateral backs. We reconstructed the right and left, upper and lower limbs using the parascapular flap and latissimus dorsi muscle flap from one side and the scapular flap and thoracodorsal artery perforator flap from the other side, in multiple stages. All four flaps survived, preserving the right and left heels and function of the bilateral wrist joints. Although there have been several reports of single-stage elevation of the combined scapular and latissimus dorsi flaps, there has been no report of multi-stage elevations of these flaps. When multiple flaps are required in multi-stage, raising the flaps based on the thoracodorsal artery and scapular circumflex artery from the ipsilateral back is a useful method because it does not require additional donor sites.

Pedicled thoracodorsal artery perforator flap in the soft-tissue reconstruction of an acute traumatic cubital fossa defect.

INTRODUCTION: Complex cubital fossa injuries with bony and vascular injuries are not an uncommon clinical presentation after trauma to the elbow. The revascularization of the upper limb by brachial artery repair with the venous graft is paramount, followed by immediate cover with a sturdy flap to salvage the limb. The use of local muscle and fasciocutaneous flaps is limited in the setting of vascular injury. The pedicled latissimus dorsi muscle flap and abdominal flaps are routinely used with few advantages. This article describes the use of a pedicled thoracodorsal artery perforator flap in the management of acute traumatic cubital fossa defect. MATERIAL AND METHODS: A retrospective observational study was performed from September 2015 to December 2020 with patients who underwent the pedicled TDAP flap as a soft-tissue cover of cubital fossa injuries primarily. Patient variables, including the size of defect and flap, the number of perforators, the complications, and the outcome, were recorded. RESULTS: Eleven patients were included in the study. The majority of the patients were males (n = 10) and presented with a history of trauma in a road traffic accident (n = 6) or because of a fall from height (n = 4). All of them (n = 11) had some form of bony injury. Seven patients in this group required brachial artery repair with an interposition vein graft successfully covered with a TDAP flap. There was a constant dominant musculocutaneous perforator about 10-13 cm from the apex of the axilla. At discharge, all flaps had settled well. On follow-up ranging from 2 months to 2 years, the patients reported satisfactory outcomes.

A cost-effectiveness analysis of delayed breast reconstruction with pedicled flaps from the back.

BACKGROUND: Variability in breast reconstruction methods provides an opportunity to investigate whether a method is superior to another with regard to cost, quality, or both. We performed a cost-effectiveness analysis (CEA) study based on tertiary endpoint data from a randomized clinical trial to compare the cost-effectiveness of delayed breast reconstruction by either a latissimus dorsi flap (LD) or a thoracodorsal artery perforator flap (TAP). MATERIAL & METHODS: A total of 50 women were included for unilateral delayed breast reconstruction and were randomized to reconstruction by either the LD flap (n = 18) or the TAP flap (n = 22). The CEA was based on differences in shoulder function after the reconstruction. Direct and indirect costs relating to the two procedures were assessed by the Danish Diagnosis-Related Groups tariffs. RESULTS: Our analysis showed a significant positive effect of introducing the TAP flap on the total shoulder score with an additional cost of $2779. The incremental cost-effectiveness ratio was $4481 and based on a willingness to pay (WTP) $500, we found an estimated net benefit of $519, which was statistically significant (p = 0.0375). The cost-effectiveness acceptability curve indicated that there is a 96.3% probability for the TAP flap being cost-effective to the LD flap at a WTP threshold of $500. CONCLUSION: From a societal perspective, our cost-effective analysis demonstrated that the TAP flap is the more cost-effective method of breast reconstruction compared to the LD flap with respect to patient-reported shoulder-related disability.

Resurfacing the donor sites of reverse sural artery flaps using thoracodorsal artery perforator flaps.

BACKGROUND: The reverse sural artery (RSA) flap is widely used for lower extremity reconstruction. However, patients sometimes suffer from donor site complications such as scar contracture and paresthesia, resulting in dissatisfaction with the aesthetic outcomes. This study investigated the characteristics of donor site morbidity associated with RSA flaps and described our experiences of dealing with complications by performing resurfacing surgery using thoracodorsal artery perforator (TDAP) flaps. METHODS: From April 2008 to August 2018, a total of 11 patients underwent contracture release and resurfacing surgery using TDAP flaps due to donor morbidity associated with RSA flaps. All affected donor sites were covered with a skin graft, the most common of which was a meshed split-thickness skin graft (six cases). RESULTS: Eight of the 11 patients (72.7%) suffered from pain and discomfort due to scar contracture, and seven (63.6%) complained of a depression scar. The donor sites were located 6.3±4.1 cm below the knee joint, and their average size was 140.1 cm². After resurfacing using TDAP flaps, significant improvements were found in the Lower Extremity Functional Scale (LEFS) scores and the active and passive ranges of motion (AROM and PROM) of the knee joint. The LEFS scores increased from 45.1 to 56.7 postoperatively (P=0.003), AROM increased from 108.2° to 118.6° (P=0.003), and PROM from 121.4° to 126.4° (P=0.021). CONCLUSIONS: Planning of RSA flaps should take into account donor site morbidity. If complications occur at the donor site, resurfacing surgery using TDAP flaps achieves aesthetic and functional improvements.

Good health-related quality-of-life and high patient-reported satisfaction after delayed breast reconstruction with pedicled flaps from the back.

BACKGROUND: This paper presents the results of a randomized controlled trial (RCT) that focus on health-related quality-of-life (QoL) and patient-reported satisfaction following breast reconstruction with pedicled flaps from the back. MATERIALS & METHODS: We included women for unilateral delayed breast reconstruction. Patients were randomized to reconstruction by either a latissimus dorsi (LD) flap or a thoracodorsal artery perforator (TAP) flap. Assessment of QoL and patient satisfaction was made using two different patient-reported outcome measures (PROMs): The EORTC QLQ-30 and the Breast-Q questionnaire for post-mastectomy breast reconstruction. RESULTS: A total of 50 women were enrolled over a two-year period and allocated to reconstruction. Forty patients completed both surgery and follow-up and were included in the analysis - 18 in the LD group and 22 in the TAP group. The EORTC QLQ-30 was administered at the baseline and at one-year follow-up. There was no significant effect of introducing the TAP flap on either the summary score, the global QoL-score or the financial impact-score when compared to the LD flap. The Breast-Q questionnaire was administered only at one-year follow-up. There was no significant difference between the two groups for the scores for satisfaction with the reconstructed breast, the overall outcome and QoL related to psycho-social, sexual and physical well-being. CONCLUSION: Women from both groups report high satisfaction and QoL following the reconstruction. The quality of the dataset and the study design are, however, insufficient to rule out any existing difference. A larger cohort, longer follow-up and different design are warranted to assess the true clinical significance these reconstructions might have on satisfaction and QoL.

[Clinical effect of free thoracodorsal artery perforator flap in reconstructing large scar on the facial subunit].

Objective: To explore the clinical effect of free transplantation of thoracodorsal artery perforator flap in reconstructing large scar on the facial subunit. Methods: From April 2014 to March 2018, 7 patients with large facial scar were admitted to Ningbo NO.6 Hospital, including 3 males and 4 females, aged from 31 to 49 years, 4 with frontal involvement and 3 with chin and neck. Color Doppler ultrasound was used for the positioning of the thoracodorsal artery perforating vessel, and scar resection was performed according to the principle of facial subunit repair. The wound area was 8 cm×6 cm-21 cm×8 cm, and the wound was repaired with the free thoracodorsal artery perforator flap in the area of 9 cm×7 cm-22 cm×9 cm. The donor site was closed directly by suturing. The consistency of the location of the perforating vessel explored during the operation with its preoperative positioning and the flap survival were recorded. The color, texture, and appearance of the flap and the healing condition, scar formation, and function of the donor area were observed during follow-up. Results: The locations of the perforating vessels of 7 patients explored during the operation were consistent with those positioned by color Doppler ultrasound before the operation. All the flaps of the 7 cases survived successfully after operation. Postoperative follow-up of 12-18 months showed that the flap color was similar to the surrounding skin of the recipient area, with soft texture and no obvious contracture. Slight bloated appearance was observed in the flaps of 4 cases. All the 7 patients had postoperative healing of the flap donor site without obvious scar hyperplasia or influence on shoulder joint function. Conclusions: The anatomy of the perforating vessel of the thoracodorsal artery perforator flap is relatively constant and the flap can be cut in large area with soft texture, good appearance, and concealed donor area, which is a good choice for reconstructing large scar on the facial subunit.

[Effect of pedicled thoracodorsal artery perforator flap on the repair of moderate to severe axillary scar contracture deformity].

Objective: To investigate the effect of pedicled thoracodorsal artery perforator (TDAP) flap on the repair of axillary moderate to severe scar contracture deformity. Methods: From January 2012 to January 2017, 29 patients with axillary moderate to severe scar contracture deformity were admitted to the the Second Xiangya Hospital of Central South University, including 18 females and 11 males, aged 14-42 years. There were 3 patients with cicatricial contracture deformity of bilateral axillas and 26 patients with cicatricial contracture deformity of unilateral axilla. After relevant preoperative examinations were completed and basic diseases were controlled, axillary scar was removed or released under the anesthesia of endotracheal intubation. The areas of wounds ranged from 7.5 cm×5.0 cm to 21.0 cm×8.5 cm after the operation. The pedicled TDAP flaps were used to repair the defects, which were thinned based on demand of the recipient sites before being transferred. The areas of flaps ranged from 9.0 cm×6.0 cm to 22.0 cm×10.0 cm. The donor sites were sutured directly. The status of thinned flaps, the survival of flaps after the operation and during follow-up, and the shoulder joint function during follow-up were observed. Results: Thirty-two pedicled TDAP flaps were harvested for repairing the defects. Among them, 14 flaps were transferred directly without thinning and the thickness of the flaps ranged from 9.0 mm to 15.0 mm, with average thickness of 13.6 mm.While the other 18 flaps were thinned, and the thickness of the thinned flaps ranged from 5.0 mm to 8.0 mm, with average thickness of 7.5 mm. The distal parts of 3 flaps in 3 patients showed small size of blackening or necrosis within 72 hours after the operation, and 2 of them were thinned and the other one was not. Finally, the 3 flaps were healed after hyperbaric oxygen therapy, dressing change, or other treatments. One flap occurred vein congestion 8 hours after the operation caused by pressure on the pedicle, and the color of the flap turned back to normal after the pressure was relieved. The rest of the flaps survived well. All the patients were followed up for 9 to 36 months, with an average of 18 months. All the flaps survived well, the color of the flaps was nearly the same as the recipient sites, and none of the flaps developed obvious contraction. The shoulder joint function of all patients was significantly improved compared with that before operation, with abduction angles of shoulder joints ranged from 90.0-145.0°, with an average of 130.0°. Conclusions: Pedicled TDAP flap is an relatively ideal choice for the repair of moderate to severe axillary scar contracture deformity, and better results will be achieved if the flaps are thinned to a appropriate thickness according to the condition of axillary defects.

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.

Shoulder-related donor site morbidity after delayed breast reconstruction with pedicled flaps from the back: An open label randomized controlled clinical trial.

BACKGROUND: This randomized controlled trial (RCT) investigates differences in shoulder-related morbidity after delayed breast reconstruction by either a latissimus dorsi (LD) flap or a thoracodorsal artery perforater (TAP) flap. MATERIAL AND METHODS: In accordance with the CONSORT guidelines, we included women for unilateral delayed breast reconstruction. Patients were randomized to reconstruction by either of the two flaps. Shoulder-function was assessed at baseline and at 3, 6 and 12 months after surgery. The primary endpoint was patient-reported shoulder-related pain. A further objective assessment by the Constant Shoulder Score (CSS) was included as secondary endpoints. RESULTS: A total of 50 women were enrolled over a two-year period and allocated to reconstruction, with 25 patients in each group. Patient-reported shoulder-related pain was significantly lower in the TAP group at 12 months after surgery when adjusting for pain at baseline: OR = 0.05 95%CI(0.005-0.51), p-value = 0.011. The estimated effect on the total CSS at 12 months, when applying the TAP flap instead of the LD flap and adjusting for the baseline score, was 6.2 points with 95%CI(0.5-12.0), p-value 0.033. The TAP flap seems to have a statistically significant positive effect on pain and activity in daily life (ADL), while there were no significant effect on range of motion and strength after one year. CONCLUSION: Patient reconstructed by the TAP flap are less likely to experience shoulder-related pain and have a better shoulder-function one year after the reconstruction. Harvest of the LD flap carries a higher risk of shoulder-function impairment, chronic pain and reduced ADL.

[Clinical application of thoracodorsal artery perforator flap in repair of serious scar contracture of opisthenar].

OBJECTIVE: To investigate the feasibility and effectiveness of thoracodorsal artery perforator (TDAP) flap for repairing serious scar contracture of the opisthenar. METHODS: Between March 2015 and June 2017, 7 cases of serious scar contracture of opisthenar were repaired with TDAP flaps. There were 5 males and 2 females with an average age of 31 years (range, 11-48 years). The time from injury to operation was 8-67 months, with an average of 42 months. After the relocation of the joint and release of the scar, the size of soft tissue defect ranged from 5 cm×4 cm to 10 cm×8 cm. The size of TDAP flap ranged from 5.5 cm×5.0 cm to 10.5 cm×9.0 cm. RESULTS: All flaps survived completely with primary healing at both donor site and recipient site. The flaps of 3 patients were bulky and underwent second-stage skin flap thinning at 3 months after operation. All 7 patients were followed up 6-32 months, with an average of 15 months. The skin flaps were soft and elastic. According to the upper limb function evaluation system recommended by Chinese Society of Hand Surgery, sensory function was classified as S3+ in 2 cases, S3+ in 1 case, S2+ in 3 cases, and S11+ in 1 case. The hand function was excellent in 2 cases, good in 4 cases, and fair in 1 case. There was no significant effect on shoulder movement. CONCLUSION: The TDAP flap is an ideal method for serious scar contracture of opisthenar.
