In many centres, the myocutaneous transverse upper gracilis (TUG) flap represents an alternative choice in autologous breast reconstruction when abdominal tissue is unavailable. However, a single TUG flap may be volume deficient, particularly in the upper pole. We describe the application of simultaneous lipofilling to the pectoralis major muscle at the index procedure and present our decision-making algorithm, technique and outcomes. A retrospective review of all TUG flaps between January 2011 and May 2021 was conducted. Patient demographics, volume of primary and any subsequent fat grafting and complications were recorded. A total of 183 patients (242 TUG flaps) were included in this study. Of these; 130 patients were reconstructed with single TUG flaps, 16 patients received a single TUG flap with immediate lipofilling, and 37 patients underwent stacked, double TUG flap reconstructions. Of the 242 flaps, there were 2 flap losses (<1%), neither of which occurred in the immediate lipofilling cohort. Among the 130 single TUG patients, 28 (21.5%) required a cumulative total of 40, and a mean of 1.4, secondary lipofilling procedures. The immediate lipofilling patients were injected with a mean of 42 ml fat (range: 20-80 ml). In this group, only 2 of 16 patients required secondary lipofilling. The mean follow-up was 67 months (17-141). Primary lipofilling may reduce the need for secondary revisional procedures and appears safe at the index operation, adds little operative time and has negligible donor site morbidity. In patients where a second (stacked) flap would add unnecessary volume and complexity, it can be considered a useful adjunct., Competing Interests: Declaration of Competing Interest None., (Copyright © 2023 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Introduction: When the deep inferior epigastric perforator (DIEP) flap is unavailable, autologous reconstruction of a moderate-to-large breast presents a surgical challenge. We retrospectively review our experience of unilateral breast reconstruction using double transverse upper gracilis (TUG) flaps and highlight specific technical considerations., Methods: Thirty-four patients underwent double TUG flaps for unilateral breast reconstruction between 2012 and 2020. The average patient age was 50 years and the average body mass index (BMI) was 23.1 kg/m 2 . In all cases, the indication for surgery was breast cancer: 31 patients had immediate reconstruction, 11 had simultaneous axillary surgery and eight had primary contralateral symmetrising surgery., Results: Of the 68 TUG flaps, 67 (98.5%) were successful. The mean operative time was 5 h 50 min (195-460 min) and the mean combined flap weight was 551 g (279-916 g). Eight patients returned to the operating theatre in the early post-operative period and five patients underwent secondary lipofilling to address contour deformities. Most commonly (n = 22), the flaps were oriented horizontally/obliquely, with one flap anastomosed medially to the internal mammary axis and the other anastomosed lateral to the subscapular system. The internal mammary artery perforators and serratus anterior artery provided the best vessel calibre match with the TUG vessels., Conclusions: Double TUG reconstruction is a safe and reliable option for unilateral breast reconstruction and is an important option when the DIEP flap is unavailable., (Copyright © 2021 Elsevier Ltd.

Introduction: This study evaluates COVID-19 related patient risk, when undergoing management within one of the largest specialist centres in Europe, which rapidly implemented national COVID-19 safety guidelines., Method: A prospective cohort study was undertaken in all patients who underwent surgical (n = 1429) or non-operative (n = 191) management during the UK COVID-19 pandemic peak (April-May 2020); all were evaluated for 30-day COVID-19 related death. A representative sample of elective/trauma/burns patients (surgery group, n = 729) were selected and also sub-analysed within a controlled cohort study design. Comparison was made to a random selection of non-operatively managed (non-operative group, n = 100) or waiting list (control group, n = 250) patients. These groups were prospectively followed-up and telephoned from the end of June (control group) or at 30 days post-first assessment (non-operative group)/post-operatively (surgery group)., Results: Complex general (9.2%, 136/1483) or regional (5.0%, 74/1483) anaesthesia cases represented 14.2% (210/1483) of operations undertaken. There were no 30-day post-operative (0/1429)/first assessment (0/191) COVID-19 related deaths. Neither the three sub-speciality plastic surgery, or non-operative groups, displayed increases in post-operative/first assessment symptoms in comparison to each other, or to control. The proportion of COVID-19 positive tests were: 7.1% (1/14) (non-operative), 5.9% (2/34) (burns) and 3.0% (3/99) (trauma); there were however no significant differences between these groups, the elective (0%, 0/54) and control (0%, 0/24) groups (p = 0.236)., Conclusion: We demonstrate that even heterogeneous sub-speciality patient groups, who required operative/non-operative management, did not incur an increased COVID-19 risk compared to each other or to control. These highly encouraging results were achieved with described, rapidly implemented service changes that were tailored to protect each patient group and staff., Competing Interests: Declaration of Competing Interest None., (Copyright © 2020 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Background: The DIEAP flap has gained popularity for breast reconstruction worldwide. Despite DIEAP flap arterial anatomy being well known, venous congestion is still an important complication and the literature on DIEAP flap venous anatomy is lacking. Venous drainage is less predictable and research on venous perforators is of increasing interest. The aim of this study was to investigate the anatomical distribution, diameters and relationships between arterial and venous perforators and their source vessels using Duplex ultrasonography, in order to evaluate the potential benefits of pre-operative evaluation of DIEAP flap venous perforators., Methods: Prospectively, 140 patients undergoing DIEAP flap breast reconstruction, were pre-operatively assessed using Duplex ultrasonography for location and diameter of arterial and venous perforators, DIEA, DIEV, and SIEV. Perforators were plotted laterally and inferiorly from the umbilicus. Means were compared using t-tests. Pearson's correlation coefficients were calculated., Results: We identified 702 arterial and 355 venous perforators in 280 lower hemi-abdomens. No venous perforators were identified in 9 (6.5%) patients; none on the right in 25 (17.9%) and none on the left in 36 (25.7%). Venous perforators were larger on the right (p=0.031) but DIEV and SIEV diameters were not statistically different on either sides. The diameters of DIEA, DIEV, perforating arteries and veins were correlated, but unrelated to the diameter of the SIEV. When a medium/large perforator vein is identified first, there is a 93.5% chance of finding an associated medium/large perforator artery; this reduces to 69.8% when a medium/large perforator artery is first identified., Conclusions: There is no correlation between the sizes of perforator veins and DIEV, and the size of the SIEV. Our data suggests that first identifying a medium/large venous perforator increases the chances of finding a better suitable perforator complex. Pre-operative evaluation of venous perforators may be of great interest for its potential clinical benefits., (Copyright © 2012. Published by Elsevier Ltd.)

Microsurgery is an essential technique in free flap reconstructions today. The technical skills involved require a learning curve, which may be affected by the current issues of limited training resources and patient safety. We describe a study on the value of a microsurgery training device as an assessment and warm up tool in basic microsurgery skills. Forty volunteers with different levels of microsurgery experience performed a microsurgical 'round-the-clock' exercise on the training device three consecutive times. Video-recordings of these performances were rated by two blinded independent assessors using a modified Global Rating Scale to assess basic microsurgery skills on the following parameters: steadiness, instruments handling and speed. Time to complete a round was also recorded objectively. The Kruskal-Wallis test was used to analyse the construct validity of the parameters assessed between the groups of level of microsurgery experience. Crohnbach's coefficient alpha was used to determine the reliability index of the independent assessors. All participants improved their time on consecutive rounds of the exercise. A median of 82 s (range 6-583 s) improvement in time between the first and third round was observed. Different mean performance time could be identified between the groups, but individual speed did not correlate significantly with microsurgery experience. Assessment of microsurgery skills using the modified Global Rating Scale demonstrated statistically significant differences for instruments handling (p=0.03) and speed (p=0.01) between the groups with regard to microsurgery experience, and improvement in the parameters assessed for all groups. Difference in steadiness (p=0.07) was not significant amongst the juniors. Consultants performed better than juniors but, at all levels of experience, significant improvement in skills was demonstrated after practice. The 'round-the-clock' microsurgery training device is an inexpensive and readily available valid tool that provides a useful warm up exercise and instant assessment of basic microsurgical skills., (Copyright 2009 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

Unlabelled: Autologous free tissue transfer is an ideal method for breast reconstruction. The deep inferior epigastric perforator (DIEP) flap is considered the gold-standard procedure worldwide. However, in selected patients this flap cannot be performed to achieve satisfactory outcomes. The transverse myocutaneous gracilis (TMG) flap is one of the most recent additions to the armamentarium of breast-reconstructive surgeons. This flap can provide adequate autologous tissue with a hidden scar. Since its description for breast reconstruction in 2004, no series have been published and its recognition is still lacking. The main criticism of this flap is the lack of volume that can be achieved and the potential for donor morbidity. We report upon a 2-year experience with the use of TMG flaps for breast reconstruction, assessing the potential indications and introducing some technical refinements in order to expand the role of this flap in breast reconstruction., Materials and Methods: Information regarding all TMG flaps performed in the period between January 2006 and December 2007 was prospectively collected. Indications and outcomes were reviewed. The surgical technique was revised and standardised to achieve a routine set-up., Results: During the study period, 19 TMG flaps were performed in 12 patients (seven double procedures: five bilateral cases and two stacked flaps for unilateral breast reconstruction). One flap was lost 9 days postoperatively. Follow-up ranged from 6 months to 2 years. We detail our surgical technique and describe refinements to speed up flap harvest, increase flap volume, optimise flap inset and minimise donor-site complications., Conclusion: Although the DIEP flap is still our preferred choice for breast reconstruction, the TMG flap is suitable as a first-line option in small-to-moderate breasted women or as a second-line choice for larger-breasted women for whom the DIEP flap may not be the preferred choice. It is also a reliable salvage flap in cases of previous flap failure., (2008 British Association of Plastic, Reconstructive and Aesthetic Surgeons. Published by Elsevier Ltd. All rights reserved.)
