Thin Free Perforator Flap as a Viable Option for Forefoot Reconstruction: Comprehensive Evaluation of Outcomes.

Reconstruction of forefoot defects often necessitates free tissue transfer due to the limited availability of local tissue. Microsurgical reconstruction of the forefoot remains challenging as it requires durable yet thin, soft tissue coverage for functional restoration. This study aimed to evaluate the efficacy of free thin perforator flaps for forefoot reconstruction, with a focus on functional outcomes. Patients who underwent microsurgical forefoot reconstruction between March 2020 and September 2023 were reviewed. Development of postoperative complications and functional outcomes were evaluated. In total 53 patients were analyzed, with a mean age of 62.7 years. The most common etiology of defects was oncologic surgery, followed by chronic wound, with a majority involving the plantar side. Super-thin anterolateral thigh flap and superficial circumflex iliac artery perforator flap were predominantly used. The median thickness of the flap was 4.0 mm. Digital vessels were the most frequently used as recipients. All but one flap survived, resulting in a success rate of 98.1 percent. Postoperative flap-site complications developed in 20 patients, the majority of which were resolved with conservative treatment. The median hospital stay was 8.0 days, and the mean time for initiating weight-bearing ambulation was 12.4 days. In postoperative foot function index questionnaire survey, the overall score remained 9.41, showing minimal impairment, and did not differ according to defect size and locations. Secondary debulking operation was necessitated in seven patients. Use of thin free perforator flaps might provide reliable outcomes with rapid recovery and excellent postoperative function in the forefoot reconstruction.

Analysis of Operation Duration in Thoracodorsal Artery Perforator Free-Flap Surgery of the Lower Extremities.

This retrospective study aimed to identify the factors that affect the duration of thoracodorsal artery perforator (TDAP) free-flap surgery and to offer strategies for optimizing the surgical procedure. We analyzed 80 TDAP flap surgeries performed by a single surgeon between January 2020 and December 2022, specifically focusing on free flaps used for lower-extremity defects with single-artery and single-vein anastomosis. The operation duration was defined as the time between the surgeon's initial incision and completion of reconstruction. Linear regression analyses were conducted to identify the factors affecting operation duration. The average operative duration was 149 minutes (range, 80-245 minutes). All flaps survived, although 8 patients experienced partial flap loss. The operative duration decreased with increasing patient age and when end-to-end arterial anastomosis was performed. However, the risk increased with larger flap sizes and in patients with end-stage renal disease. Our study identified several factors and methods that could accelerate TDAP free-flap procedures. These findings offer valuable insights for optimizing surgical processes and improving overall surgical outcomes. Although further research is needed to confirm and expand upon these findings, our study provides important guidance for surgeons in developing effective strategies for TDAP flap surgery.

Head and neck reconstruction with the superficial circumflex iliac artery perforator (SCIP) free flap: Lessons learned after 73 cases.

Head and neck tissue defects after ablative surgery often require complex and composite reconstructions. The superficial circumflex iliac artery perforator (SCIP) flap is an extremely versatile perforator-based flap with minimal donor site morbidity, which may represent the optimal procedure in this setting. Over the last 5 years, we collected a large base of experience, including both simple and chimeric SCIP-based reconstruction, making this flap our first choice for head and neck reconstructions. Seventy-three patients undergoing ablative head and neck surgery for oncologic pathologies were treated by means of a SCIP flap reconstruction. Patients' mean age was 67 years old (range 37-89), 51 were males and 22 were females. Fifty-eight flaps were simple and 15 were chimeric reconstruction patterns. Indocyanine green perfusion imaging was performed in all cases. All the patients were successfully treated with no flap losses were encountered. Twelve patients encountered postoperative complications: in four cases revision surgery was required for venous congestion, while the remaining cases were managed conservatively (four wound dehiscence and three infections). No patients showed donor site complications. The mean follow-up period was 11 months (range 3-24). Our case series demonstrates the reliability and versatility of the SCIP flap for different kinds of head and neck reconstructions. The chimeric options combined with bone, double skin paddle, and muscle offer a broad variety of functional reconstructive solutions for complex head and neck surgeries. Intraoperative indocyanine green perfusion examination provides a valuable tool to assess and ascertain proper vascularization and post-anastomosis vessel patency in complex microvascular flap-based reconstructions.

An Effective Protocol for Perioperative Venous Thromboembolism Prophylaxis in DIEP Flap Breast Reconstruction: A Single Institution Retrospective Review.

Deep inferior epigastric artery perforator (DIEP) free flap breast reconstruction is one of the most highly used procedures for autologous breast reconstruction. Many venous thromboembolism (VTE) risk assessment models have been proposed in breast reconstructive surgery, including the widely used Caprini score. However, a paucity of data suggests an effective standardized VTE protocol. The purpose of this study was to determine the rate of VTE in our DIEP flap patients who were treated with this protocol. A retrospective single-center review of DIEP flap breast reconstruction from 2016 to 2021 was performed. Data were collected on 554 patients and 893 flaps including demographics, intraoperative and perioperative details, and postoperative course. Patients who were not treated with our standard protocol were excluded. Data were analyzed with alpha = 0.05. The average age was 50.4 ± 9.9 years, and the total follow-up time was 16.9 ± 12.6 months. The average body mass index for the cohort was 30.1 ± 5.2. During the 90 postoperative days, the mean length of hospital stay was 4.3 days. There were six cases of postoperative VTE: five patients presented with pulmonary embolism (0.9%) and one patient (0.2%) had deep venous thrombosis with an overall VTE prevalence of 1.1%. No specific single factor could be attributed to VTE occurrence. Using our standardized VTE prophylaxis protocol, our institution was effective at keeping VTE rates low. Additional studies would be beneficial to determine optimal VTE prophylaxis protocols in higher-risk patients, such as those with known clotting disorders.

Smartphone-based thermography in flap surgery: A systematic review and meta-analysis of perforator identification

BackgroundThermography can be used in pre-operative planning of free perforator flap surgeries. Thermography assesses skin temperature by measuring the quantity of infrared radiation observed. In this meta-analysis, authors assess the sensitivity of smartphone-based thermal imaging (SBTI) in the detection of perforators and analyze the difference between static and dynamic imaging. Materials and methodsAuthors followed the PRISMA guidelines for systematic reviews and meta-analyses. The meta package in R was used to conduct the meta-analysis. The “metaprop” function was used to calculate the overall sensitivity estimate and 95% confidence interval. The “metaprop.one” function was used to calculate subgroup estimates for static and dynamic study types. The “metareg” function was used to conduct meta-regression analyses to explore sources of heterogeneity. ResultsThis study includes seven articles with 1429 perforators being evaluated. The overall proportion of the sensitivities was estimated to be 0.8754 (95% CI: 0.7542; 0.9414) using a random effects model. The heterogeneity of the studies was high, as indicated by the tau^2 value of 1.2500 (95% CI: 0.4497; 8.4060) and the I^2 value of 92.6% (95% CI: 88.1%; 95.4%). The pooled sensitivity for static imaging was 0.8636 (95%CI: 0.6238–0.9603) with a tau^2 of 2.0661 and a tau of 1.4374, while the pooled sensitivity for dynamic imaging was slightly higher (p = 0.7016) at 0.8993 (95%CI: 0.7412–0.9653) with a smaller tau^2 of 0.8403 and a tau of 0.9167. ConclusionFurther studies need to confirm that SBTI is a reliable and convenient technique for detecting perforators for the pre-operative planning of free perforator flap surgeries.

Comparison of complications and functional outcomes following total or subtotal glossectomy with laryngeal preservation using a deep inferior epigastric artery perforator free flap versus a rectus abdominis musculocutaneous free flap

ObjectiveWide defects resulting from subtotal or total glossectomy are commonly reconstructed using a bulk flap to maintain oral and speech functions. The flap, including muscle tissue, diminishes with time. This study aimed to compare the surgical outcomes of deep inferior epigastric artery perforator and rectus abdominis musculocutaneous free flap reconstructions after glossectomy with laryngeal preservation. MethodsMedical records of 13 and 26 patients who underwent deep inferior epigastric artery perforator and rectus abdominis musculocutaneous free flap reconstructions, respectively, from 2014 to 2022 at our institution were reviewed. Patients who underwent middle pharynx resection except for the base of the tongue, mandibular bone resection, and sensory reinnervation were excluded. ResultsThe rectus abdominis musculocutaneous groups showed a higher number of lymph node dissection and shorter operative time than the deep inferior epigastric artery perforator groups. No significant differences in postoperative complications or functional oral intake scale scores at 6 months were observed. Volumetric changes on computed tomography images at 6 and 12 months were significantly lower in the deep inferior epigastric artery perforator group. Cancer recurrence was significantly associated with reduced oral function. ConclusionOral function in patients with cancer is influenced by various other factors. However, the deep inferior epigastric artery perforator flap may be suitable for tongue reconstruction because of the minimal postoperative changes in flap volume, easy adjustment of flap thickness, elevation of multiple flaps, and minimal complications at the donor site.

DIEP Donor Site Satisfaction between Patients with and without History of Pregnancy.

With the success of free autologous breast reconstruction, the abdominal donor site is now an important consideration, especially in patients of childbearing age. In our institution, there are increasing patients who have successfully undergone the deep inferior epigastric artery perforator (DIEP) flap despite previous pregnancy. This study aims to answer questions on the effect of the donor site on pregnancy and vice versa. A retrospective cohort study was conducted to identify breast cancer patients who received a free DIEP flap for breast reconstruction from January 2018 to August 2020. Patients were allocated to two groups according to whether they had prior pregnancies with successful deliveries. Demographics, flap-related parameters, surgical outcomes on breast and abdomen, and patient-reported outcome (Breast-Q questionnaire) were analyzed. Patients were excluded if follow-up time was less than 1 year, or if there was incomplete medical records or Breast-Q replies. Ninety-nine of 116 patients had had successful pregnancies with delivery, 17 of them remained nulliparous. No statistically significant differences existed between groups regarding demographic data, flap-related parameters, surgical outcomes on breast and abdomen. Nulliparous patients exhibited significantly lower score in physical well-being in the abdomen domain compared with delivery-experienced patients (62.1 vs. 73.4, p = 0.025). Significantly, nulliparous patients felt more tightness and pulling of the abdominal wall than the delivery-experienced patients (2.9 vs. 3.7; p = 0.05 and 3.5 vs. 4.0; p = 0.04). Free DIEP flap can be transferred safely in nulliparous patients despite a slight increase in abdominal tightness and abdominal pulling. Precise flap design and surgical approaches may help to minimize the abdominal discomfort especially on young, normal body mass index, and nonchildbearing patients.

Abdominal donor-site complications following autologous breast reconstruction: A multi-institutional multisurgeon study

BackgroundThe deep inferior epigastric perforator (DIEP) free flap is the gold standard procedure for autologous breast reconstruction. Although breast-related complications have been well described, donor-site complications and contributing patient risk factors are poorly understood. MethodsWe examined a multi-institutional, prospectively maintained database of patients undergoing DIEP free flap breast reconstruction between 2015 and 2020. We evaluated patient demographics, operative details, and abdominal donor-site complications. Logistic regression modeling was used to predict donor-site outcomes based on patient characteristics. ResultsA total of 661 patients were identified who underwent DIEP free flap breast reconstruction across multiple institutions. Using logistic regression modeling, we found that body mass index (BMI) was an independent risk factor for umbilical complications (odds ratio [OR] 1.11, confidence interval [CI] 1.04–1.18, p = 0.001), seroma (OR 1.07, CI 1.01–1.13, p = 0.003), wound dehiscence (OR 1.10, CI 1.06–1.15, p = 0.001), and surgical site infection (OR 1.10, CI 1.05–1.15, p = 0.001) following DIEP free flap breast reconstruction. Further, immediate reconstruction decreases the risk of abdominal bulge formation (OR 0.22, CI 0.108–0.429, p = 0.001). Perforator selection was not associated with abdominal morbidity in our study population. ConclusionsHigher BMI is associated with increased abdominal donor-site complications following DIEP free flap breast reconstruction. Efforts to lower preoperative BMI may help decrease donor-site complications.

Anatomical features of a crossing vein connecting left and right internal mammary veins: A preliminary study with computerized tomography or magnetic resonance imaging.

In breast reconstruction with free flaps, retrograde venous anastomosis into the internal mammary vein (IMV) is often unavoidable. Utility of a crossing vein between the right and left IMV, one of the anatomical foundations which make retrograde flow possible, has been reported but only with a few detailed features. This study evaluated the presence, actual location, and diameter of the crossing veins using preoperative imaging such as contrast-enhanced computed tomography (CECT), or contrast-enhanced magnetic resonance imaging (CEMRI). Moreover, this is a preliminary non-invasive study to clarify these processes on a larger scale. We included 29 cases of unilateral breast reconstruction performed between July 2018 and September 2023 at our institution using unipedicled or bipedicled free deep inferior epigastric artery perforator (DIEP) flaps with retrograde venous anastomosis to only one IMV at the level of anastomosis. No congestion or necrosis was observed. In the final 24 cases with sufficient imaging coverage of preoperative contrast-enhanced images (15 CECT and 9 CEMRI), the crossing veins of IMVs were detected and the number, localization, and diameter were measured. In 20 cases of 24 images, the crossing veins between IMVs were completely identified (83%). In 18 of the cases, only one crossing vein was established immediately ventral to the xiphoid process, averaging 19.3 ± 7.18 mm caudal to the fibrous junction between the sternal body and xiphoid process. The average diameter of the veins was 1.57 ± 0.42 mm. In two other cases, the second crossing vein originated on the dorsal surface of the sternum, but it was a very thin vein of about 0.4 mm. Three images indicated incomplete identification of the crossing vein at the xiphoid process, and in one case, no crossing vein was observed between bilateral IMVs. The contrast-enhanced imaging study revealed an anatomic feature that the crossing veins (about 1.5 mm in diameter) connecting the right and left IMVs are located just ventral to the xiphoid process. Furthermore, the crossing veins can be identified on contrast-enhanced images, and refinement of this method is expected to lead to future non-invasive anatomical investigations in an even larger number of cases.

The Value of Anterolateral Thigh Free Flap for the Reconstruction of Malignant Melanoma of the Sole of the Foot.

Wide excision of malignant melanoma on the foot usually results in an extensive function-destroying defect, and the reconstruction of foot defects remains challenging for reconstructive surgeons. We propose using anterolateral thigh perforator (ALT) free flaps for the reconstruction of widespread defects caused by malignant melanoma in the sole. This retrospective study included 34 patients who underwent reconstruction of sole defects caused by malignant melanoma resection with 35 ALT perforator free flaps between August 2005 and July 2021. In total, 18 male patients and 16 female patients were included (mean age at surgery, 65.4 years). The mean size of the flaps was 100.4 cm 2 . Thirty-three of the 35 flaps survived. Hematoma, seroma, and chronic ulceration were not identified in any cases. All patients achieved independent ambulation within the follow-up period, except 1 patient with gait discomfort. The 5-year overall and disease-free survival rates of patients were 64.4% and 56.6%, respectively. The ALT flap is a versatile surgical option that should be considered for reconstruction of the sole after malignant melanoma resection, considering its various surgical advantages and the functional aspects of independent ambulation, the aesthetic aspects of wearing conventional footwear, and the anatomical aspects of the sole.

Pre-expanded thin DIEP free flap in pediatric upper extremity reconstruction for burn sequelae: A case report

Deep burns sequelae involving the upper limb are challenging even for experienced surgeons, mainly because local reconstructive options and donor sites are often compromised. The use of free flaps for this type of reconstruction remains difficult due to the small recipient vessel diameter and tendency to vasospasm. Moreover, pediatric cases bring the challenge to another level. We present the case of a 13-year-old girl presenting major retractile sequelae of the upper left limb, including complete wrist immobilization combining wrist hyper-extension, ulnar deviation deformity, and a ulno-carpal dislocation. She was referred to our department where a two-stage reconstruction was performed using a pre-expanded free deep inferior epigastric artery perforator (DIEP) flap. The first surgery consisted of placing two kidney-shaped expanders in a subfascial plane in the hypogastric region. Four months later, after a bi-weekly expansion, an excision of the scar tissue, and the DIEP flap transfer were completed. At the 12-month follow-up evaluation, both aesthetic and functional results were satisfactory, with a good contour and regained mobility of the wrist.

Management of breast cancer—related lymphedema using free medial sural artery perforator (MSAP) flap: a VLVT approach

Management of breast cancer—related lymphedema using free medial sural artery perforator (MSAP) flap: a VLVT approach

Comparative Study of Small Vessel (under 0.8 mm) Anastomosed Free Flap and Larger Vessel (over 0.8 mm) Anastomosed Free Flap: Does Supermicrosurgery Provide Sufficient Blood Flow to the Free Flap?

This study aimed to quantify the blood flow of free flaps and compare the blood flow of small vessel (<0.8 mm) and larger vessel (>0.8 mm) anastomosed free flaps. This retrospective study included patients treated successfully with a perforator free flap in the lower extremity between June 2015 and March 2017. A color duplex ultrasound system measured the flow volume through the pedicle by analyzing the mean flow peak velocity, flow volume, and flow volume per 100 g of the flap. A total of 69 patients were enrolled in this study. There was no statistical difference in peak velocity between the small vessel anastomosed free flap (25.2 ± 5.6) and larger vessel anastomosed free flap (26.5 ± 5.4). Flow volume (6.8 ± 4.2 vs. 6.3 ± 3.6) and flow volume/100 g (3.6 ± 3.9 vs. 6.2 ± 6.9) also did not show significant differences. Small vessel (<0.8 mm) free flaps showed similar flow velocity and flow volume to larger vessel (>0.8 mm) anastomosed free flaps. Blood flow to the small vessel anastomosed free flap was sufficient despite its small vessel size.

A cadaveric study and clinical application of the free superficial circumflex iliac artery perforator flap reconstruction of limb soft tissue defects

Introduction In recent decades the superficial circumflex iliac artery perforator (SCIP) flap technique has gradually overcome the previous disadvantages of its pedicle and donor site to be widely applied in treating tissue's defects. This article investigates the vascular anatomy of the SCIP flap and evaluates the result of using the flap to reconstruct limb defects. Materials and Methods The study was performed in two parts. Firstly a cross-sectional descriptive anatomical study comprising 49 groin dissections in 25 cadavers, with contrast radiographic demonstration of the vascular anatomy. Secondly a retrospective case series of 51 free SCIP flaps in 49 patients. Surgical outcomes were evaluated using the Vancouver Scar Scale on the regional function and the aesthetics of implanted flap and donor sites. Results The results of anatomical analysis on cadavers showed the superficial circumflex iliac arteries were detected in all specimens with an average diameter of 1.4 ± 0.3 mm. The superficial subcutaneous venous systems were also recorded, including two veins (superficial circumflex vein and superficial epigastric vein) in 79.5% with an average diameter of 2.3 ± 0.6 mm. The flap results showed the alive flap rate was 90.2%, partial-necrosis flap was 3.9% and total necrosis of the flap in 5.9%. In the aesthetic evaluation, fine line scars were seen in 13/51 cases (25.5%), stretch scars in 33/51 cases (64.7%) and hypertrophic scars in 5/51 patients (9.8%), with no cases of keloid scars. Conclusion The SCIP flap is a reliable free-tissue transfer for reconstructing limb soft tissue defects. Moreover, the SCIP flap is an ideal flap with pleasing aesthetics because the donor-site scar is situated in a well-hidden site. Care must be taken when vein grafts are used to lengthen the flap as flap necrosis rates increase.

The Free Medial Sural Artery Perforator Flap for Microsurgical Reconstruction of Limbs: A Systematic Review and Meta-Analysis of Flap Characteristics and Outcomes

The medial sural artery perforator (MSAP) continues to gain popularity. Providing a versatile, thin and pliable alternative for commonly used workhorse flaps, it can be used to reconstruct extremities, with reduced donor site morbidity. This meta-analysis was conducted to analyse the current literature to help identify flap characteristics and outcomes. A systematic review was performed following the preferred reporting items for systematic reviews and meta-analysis (PRISMA) guidelines and a literature search was conducted using Medline, Google Scholar and the Cochrane Library. The aim was to identify the outcomes of free MSAP flap reconstructions of upper and lower limb defects over a 10-year period from January 2010 to July 2020. The data was then tabulated and a meta-analysis was carried out. A total of 11 studies for lower limbs and 7 studies for upper limbs were reviewed and analysed with a total number of 257 patients. Limb reconstructions were primarily due to trauma. The most common site of reconstruction of the upper limb was the hand or wrist and the lower limb was the ankle or feet. The mean length of the flap was 9.6 cm. The mean width was 5.4 cm. The mean pedicle length was 9.7 cm. The mean flap thickness was noted as 5.9 mm. The number of perforators was an average of 1.5. The pedicle’s mean arterial diameter was 1.9 mm (mean) and the vein’s mean arterial diameter was 2.9 mm. 80% of donor sites were closed directly. Overall, the flap success rate was 98%. Our results find the MSAP flap to be a versatile, reliable, functionally and aesthetically good reconstructive option for both lower and upper limb defects with low donor site morbidity.

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

BackgroundThe 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. MethodsSeveral databases were screened for relevant citations. The quality of studies and risk of bias were evaluated using the MINORS scoring system. ResultsTwenty 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. ConclusionsBased 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.

Reconstruction of extensive scalp defects of oncologic origin using thoracodorsal artery perforator free flaps

Purpose: Ablation of malignant neoplasms of the scalp usually leaves extensive defects. Free musculocutaneous transfer using the latissimus dorsi muscle with a skin graft has been the gold standard for restoring such defects; however, this approach may be limited by potential functional morbidity and delayed healing of the grafted skin. This study presents a case series of microsurgical reconstruction with thoracodorsal artery perforator (TDAP) flaps for extensive scalp defects after radical oncologic resection.Methods: Consecutive patients with malignant scalp tumors who underwent wide local excision and defect coverage with TDAP free flaps between April 2019 and January 2023 were evaluated. Operation-related data and surgical outcomes, including donor- and recipient-site complications, postoperative shoulder function, and aesthetic results, were thoroughly assessed. As an oncologic outcome, local recurrence was also recorded.Results: Eleven patients who underwent reconstruction with an average flap size of 223.2 cm&lt;sup&gt;2&lt;/sup&gt; (range, 160.0–406.0 cm&lt;sup&gt;2&lt;/sup&gt;) were identified. The flaps were based on an average of 2.4 perforators. The donor-site wound was closed primarily in all cases. All flaps achieved complete wound healing within an average of 2 weeks and presented stable resurfacing of the scalp with satisfactory morphological outcomes. No functional shoulder disability was observed in the postoperative period. Five patients exhibited local recurrence but were appropriately treated in a timely manner.Conclusion: The free TDAP flap could be a potential, effective reconstructive tool for extensive scalp defects of oncologic origin and can overcome the recipient- and donor-site complications associated with the conventional procedure.

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.

Bilateral Free Deep Inferior Epigastric Artery Perforator Flaps for Reconstruction following Mastectomy in Poland Syndrome Patients.

Poland syndrome is classically described as symbrachydactyly, with hypoplasia of the pectoralis major and other upper thoracic musculoskeletal structures. It is thought to be caused by intrauterine interruption in subclavian arterial flow and often includes breast hypoplasia. Affected vasculature can pose a challenge for reconstruction with free flaps because inflow may not be reliable in this patient population. We present the rare case of a 28-year-old woman with left-sided Poland syndrome, significant family history of breast cancer, and BRCA1+ mutation who underwent bilateral prophylactic nipple-sparing mastectomies with successful immediate bilateral deep inferior epigastric artery perforator free flap reconstruction. The surgical literature in this clinical scenario is also reviewed. Preoperative computed tomography angiography of the chest successfully demonstrated the patency and quantified the caliber of the internal mammary vessels to support free flap breast reconstruction. Free tissue transfer is a viable option for breast reconstruction in patients with Poland syndrome undergoing mastectomy guided by preoperative computed tomography angiography to characterize the internal mammary vasculature.
