An unusual “venous circle” of the internal mammary vein encountered during microvascular anastomosis and implications for practice

The internal mammary vessels are commonly used for anastomosis in breast reconstruction. The anatomy when using the 2nd ICS has been shown to be predictable and hence preferentially used by the senior author. We present an unusual case of internal mammary vein bifurcation and immediate confluence forming a ‘venous circle’

Barriers and Facilitators to Breast Reconstruction in Ethnic Minority Women – a Systematic Review

Introduction: Post-mastectomy breast reconstruction (PMBR) is an important component of the multidisciplinary care of breast cancer patients. Despite the improved quality of life, significant racial disparities in the receipt of PMBR exist. Given the increasing population of Black, Asian and minority ethnic (BAME) women in UK, it is important to address this disparity. Our review aims to identify the barriers and facilitators influencing the uptake of PMBR in BAME women and raise awareness for physicians on interventions that could improve uptake of PMBR in BAME women.Methods: The methodology outlined by the Cochrane guidelines was used to structure this systematic review. Systematic searches for qualitative studies on barriers and/or facilitators to PMBR in ethnic women published in English were conducted. The following databases were searched from their inception up to June 2019: MEDLINE, EMBASE, PubMed, Cochrane Library, Google Scholar and Scopus. Reference lists of all included articles and relevant systematic reviews were also hand-searched for possible additional publications. Publication year or status restrictions were not applied. Only full text articles published in English and by peer reviewed journals are included. Exclusion criteria: quantitative studies on barriers and/or facilitators to PMBR, abstracts, conference proceedings, non-English language, non-specific to BAME women. A thematic synthesis approach was used through the development of sub- themes and themes from the findings of the included qualitative studies. Results: Five studies satisfied the inclusion and exclusion criteria. Three overarching themes emerged from our review: physician-associated factors (physician recommendations), patient-associated factors (knowledge, language, community and cultural, emotions, logistics, patient characteristics) and system-associated factors (insurance coverage, income status).Conclusion: Our systematic review suggests that there is a paucity of data in the literature on the barriers and facilitators to PMBR in BAME women. Considering the expanding population of BAME women and rising breast cancer incidence, it is imperative that future research in this field is carried out. Physician and patient-associated factors were identified as the most important yet modifiable factors. Adopting a combination of culturally tailored interventions targeting these factors may help improve the access of PMBR in BAME women

Assessment of breast symmetry in breast cancer patients undergoing therapeutic mammaplasty using the Breast Cancer Conservation Therapy cosmetic results software (BCCT.core)

Background: Therapeutic mammaplasty (TM) is a standard oncoplastic technique utilising aesthetic breast reduction principles to facilitate tumour resection and breast reshaping. Simultaneous contralateral mammaplasties are often performed to maintain symmetry. BCCT.core software, which principally assesses breast symmetry, has been previously employed for evaluating cosmetic results after standard breast conservation therapy and latterly TMs for upper pole tumours. The purpose of this study was to validate this novel tool for TMs in all breast zones. Methods: Standardised photographs of 20 consecutive patients who underwent TM were evaluated for symmetry using BCCT.core versus a plastic surgical panel completing a visual analogue scale. Results were rated as (excellent/good/fair/poor). Outcomes between the two methods were compared. Results: Twenty patients aged 37 to 63 years with a median 36G bra size had 22 TMs (18 unilateral, 2 bilateral). Indications were invasive breast cancer (87%) and ductal carcinoma in situ (DCIS) (13%). The median (range) tumour size was 22.5 mm (6–90 mm) with a resection weight of 245.8 g (16–1,079 g). Primary nipple pedicles were superomedial (63%), inferior (21%) and superolateral (16%). Five patients required a secondary glandular pedicle for volume redistribution to maintain breast shape. The BCCT.core software vs. panel symmetry assessments were 37% vs. 39% (excellent), 63% vs. 50% (good) and 0% vs. 11% (fair). Wilcoxon matched-pairs sign rank tests and Spearman rank correlations found the pairings to be statistically significant (P<0.05). Conclusions: Despite small patient numbers, BCCT.core gave comparable findings with the panel and is thus useful for objectively assessing cosmesis of TMs in all breast zones

Initial Management of Traumatic Digit Amputations: A Retrospective Study of Functional Outcomes

BACKGROUND:  Traumatic amputation of one or more digits can have a serious detrimental effect on social and economic standings which can be mitigated by successful replantation. Little has been recorded on preoperative management before replantation and how this affects the outcomes of the replanted digit. METHODS:  A retrospective cohort study was conducted and data collected over an 18-month period. Three protocols for preoperative management were examined: minimal (basic wound management), complete Buncke (anticoagulation, dry dressing on amputate placed on indirect ice and absence of a digital block), and incomplete (any two or three criteria from complete Buncke in addition to the minimal) protocols. Data was collected on survival rate, secondary operations, and complication rate. Function was defined by sensation, range of movement, and strength. RESULTS:  Seventy four of 177 digits were replanted with an overall survival rate of 86.5%. The rates for minimal, incomplete, and complete protocols were 95%, 87%, and 91%, respectively, and not significantly different. The complication rate was significantly different between the complete (20%) and minimal (60%) protocols (p = 0.0484). Differences in sensation and grip strength were statistically significant between protocols (p = 0.0465 and p = 0.0430, respectively). Anticoagulation, no digital block and dry gauze all showed reduced complication rates in comparison to their counterparts. CONCLUSIONS:  The Buncke protocol, which includes anticoagulation, no digital block, and dry gauze, was found to significantly reduce the complication rate which suggests that it prevents compromise of tissue integrity. Significant differences were found between protocols for sensation and grip strength. A higher-powered study is needed to investigate the effects of preoperative management on complication rates and functional outcomes

The effect of CT angiography and venous couplers on surgery duration in microvascular breast reconstruction: a single operator’s experience

Background: The use of CT angiography (CTA) or venous couplers (VCs) has led to shorter operative times in free flap breast reconstruction (FFBR). However, there are no reports on the effect of these two interventions relative to each other or combined. Methods: Abdominal based FFBRs performed by a single surgeon before introduction of either intervention were compared to those with VC only, and those after the addition of CTA to VCs (CT-VC). Operative time was defined as from “knife-to-skin” to insertion of the last stitch. Results: One hundred and twenty patients; 40 without intervention (WI), 40 with VC, and 40 with CT-VC. Introduction of VCs did not significantly reduce operative time compared to WI (P=0.73). However, patients in the CT-VC group had significantly shorter operations vs. WI (472 vs. 586 min, P<0.00001) and vs. VC alone (472 vs. 572 min, P=0.0006). Similarly, introduction of each intervention showed a stepwise decrease in ischaemia time (WI vs. VC: 100 vs. 89 min, P=0.0106; VC vs. CT-VC: 89 vs. 80 min, P=0.0307; WI vs. CT-VC: 100 vs. 80 min, P<0.00001). Conclusions: Combination of CTA and VC significantly reduced operative and ischaemic times for FFBR; this was predominantly due to use of CTA. CTA mitigates the surgical learning curve as demonstrated by shorter operating times via providing a vascular anatomy roadmap, thus facilitating flap harvest

Implications of abnormal abdominal wall computed tomographic angiography findings on postmastectomy free flap breast reconstruction.

BACKGROUND: Preoperative computed tomography angiography (CTA) of the abdominal wall vessels is used when planning free flap breast reconstruction (FFBR) because it provides a surgical road map which facilitates flap harvest. However, there are few reports on the effect of abnormal findings on the operative plan. METHODS: We conducted a retrospective study of all FFBRs performed at a tertiary referral center over a 6-year period (November 2011 to June 2017). One consultant radiologist reported on the findings. Details on patient demographics, CTA reports, and intraoperative details were collected. RESULTS: Two hundred patients received preoperative CTAs. Fourteen percent of patients (n=28) had abnormal findings. Of these findings, 18% were vascular anomalies; 36% tumorrelated and 46% were "miscellaneous." In four patients, findings subsequently prevented surgery; they comprised a mesenteric artery aneurysm, absent deep inferior epigastric (DIE) vessels, bilateral occluded DIE arteries, and significant bone metastases. Another patient had no suitable vessels for a free flap and the surgical plan converted to a pedicled transverse rectus abdominis musculocutaneous flap. The remaining incidental findings had no impact on the surgical plan or appropriateness of FFBR. More than one in 10 of those with abnormal findings went on to have further imaging before their operation. CONCLUSIONS: CTA in FFBR can have a wider impact than facilitating surgical planning and reducing operative times. Incidental findings can influence the surgical plan, and in some instances, avoid doomed-to-fail and unsafe surgery. It is therefore important that these scans are reported by an experienced radiologist

The clinical significance of oestrogen receptor expression in breast ductal carcinoma in situ

Background: Oestrogen receptor (ER) in invasive breast cancer (BC) predicts response to endocrine therapy (ET) and provides prognostic value. In this study, we investigated the value of ER expression in ductal carcinoma in situ (DCIS) in terms of outcome and the impact on ET decision.Methods: 643 pure DCIS, diagnosed at Nottingham University Hospitals, were assessed for ER. Clinicopathological data were correlated against ER status together with assessment of recurrence rate.Results: ER-positivity was observed in 74% (475/643) of cases. ER positivity was associated with clinicopathological variables of good prognosis; however, outcome analysis revealed that ER status was not associated with local recurrence. In the intermediate and high-grade ER-positive DCIS, 58% (11/19) and 63% (15/24) of the recurrences were invasive, respectively, comprising 7% and 6% of all ER-positive DCIS, respectively. Invasive recurrence in low-grade DCIS was infrequent (2%) and none of these patients died of BC. The ER status of the recurrent invasive tumours matched the primary DCIS ER status (94% in ipsilateral and 90% of contralateral recurrence).Conclusion: The strong correlation between DCIS and invasive recurrences ER status and the clinical impact of ET justify discussion of the use of ET in ER-positive DCIS treated by breast conserving surgery. The excellent outcome of low-grade DCIS, which was almost always ER- positive, does not, in the opinion of authors, justify the use of risk reducing ET. Therefore, the decision on ET for DCIS should be personalised and consider grade, ER status and other characteristics

Breast cancer management pathways during the COVID-19 pandemic: outcomes from the UK ‘Alert Level 4’ phase of the B-MaP-C study

Abstract: Background: The B-MaP-C study aimed to determine alterations to breast cancer (BC) management during the peak transmission period of the UK COVID-19 pandemic and the potential impact of these treatment decisions. Methods: This was a national cohort study of patients with early BC undergoing multidisciplinary team (MDT)-guided treatment recommendations during the pandemic, designated ‘standard’ or ‘COVID-altered’, in the preoperative, operative and post-operative setting. Findings: Of 3776 patients (from 64 UK units) in the study, 2246 (59%) had ‘COVID-altered’ management. ‘Bridging’ endocrine therapy was used (n = 951) where theatre capacity was reduced. There was increasing access to COVID-19 low-risk theatres during the study period (59%). In line with national guidance, immediate breast reconstruction was avoided (n = 299). Where adjuvant chemotherapy was omitted (n = 81), the median benefit was only 3% (IQR 2–9%) using ‘NHS Predict’. There was the rapid adoption of new evidence-based hypofractionated radiotherapy (n = 781, from 46 units). Only 14 patients (1%) tested positive for SARS-CoV-2 during their treatment journey. Conclusions: The majority of ‘COVID-altered’ management decisions were largely in line with pre-COVID evidence-based guidelines, implying that breast cancer survival outcomes are unlikely to be negatively impacted by the pandemic. However, in this study, the potential impact of delays to BC presentation or diagnosis remains unknown

The Use of Fractionated Ablative Lasers as a Transdermal Microporation Technique

Fractionated lasers have acceptable aesthetic outcomes with reduced side effects for the patient. This technology could be applied for other uses such as laser assisted transdermal delivery (TDD). This technology has been demonstrated as feasible in an in vitro setting. The purpose of this thesis was to investigate if this could be translated from the laboratory bench into clinical practice. The histopathological mechanism generated by fractional lasers for facilitating TDD was elucidated with a series of in vivo studies utilizing a porcine animal model. Abdominal skin of a pig was subject to different laser settings and biopsy samples taken for histological analysis. The histopathological pattern generated by the laser was analyzed to determine optimum laser settings. The same animal model was then used to demonstrate systemic absorption of a topically applied study drug (lidocaine). The effect of laser setting in relation to drug absorption was examined by serum blood sampling. In addition, adipocyte derived stem cells were delivered to the dermis. Subsequently a human clinical model was used to prove that laser assisted TDD can be clinically applicable. Patients were subjected to a facial rejuvenation laser procedure prior to application of the study drug and serial blood serum levels were taken. Laser type and influence on systemic absorption of the topically applied study drug (lidocaine) was then investigated. Histopathologically fractionated lasers partially ablated the stratum corneum, and perforated the underlying epidermis/dermis creating ‘microchannels’ which allowed absorption of lidocaine and stem cells. The depth and thermal injury of these microchannels could be determined by changing the laser settings. Enhanced systemic absorption of a topically applied study drug was successfully demonstrated in both animal and human clinical models. The amount of drug absorbed could be manipulated by altering laser settings, but also influenced by factors such as intrinsic enzymatic rate
