Abstract
BACKGROUND Lower extremity trauma often necessitates reconstruction with flap transfer. One of the reconstructive goals is a thin soft tissue coverage with appropriate contour. Therefore, a secondary debulking of the flap is usually performed. METHODS Debulking through conventional lipectomy is compared with liposuction followed by excision of the defatted flap excess. Demographic data, surgical details, and postoperative outcomes are compared and analyzed. The perfusion dynamics of the flaps undergoing liposuction debulking are studied by means of perioperative indocyanine green fluorescence angiography, as well as postoperative laser Doppler imaging. RESULTS Patients undergoing lipectomy (n = 69; 57.5%) or liposuction (n = 51; 42.5%) debulking had a similar rate of postoperative complications. Partial necrosis was observed in 7.2% (lipectomy) versus 7.8% (liposuction) of flaps. Fluorescence angiography showed a substantial decrease in flap perfusion following the infiltration with an epinephrine-containing tumescent solution (74.3% ± 8.2% prior to infiltration versus 16.8% ± 7.1% after infiltration; p < 0.001), resulting in a dark flap appearance. Laser Doppler imaging confirmed the hypoperfusion on postoperative day 1. CONCLUSION Secondary debulking of a lower extremity flap can be safely and efficiently performed through liposuction combined with peripheral excision of the defatted flap in a single stage. Perfusion studies may show a misleading hypoperfusion of the defatted flap, which does not accurately predict subsequent necrosis or complications.

Abstract
BACKGROUND A variety of breast reconstruction (BR) options are available. The significance of timing on outcomes remains debated. This study aims to compare complications in breast cancer patients undergoing implant-based and autologous BR immediately after mastectomy or at a delayed time point. METHODS We reviewed the ACS-NSQIP database (2008-2021) to identify all female patients who underwent BR for oncological purposes. Outcomes were stratified by technique (implant-based versus autologous) and timing (immediate versus delayed), and included 30-day mortality, reoperation, (unplanned) readmission, and surgical and medical complications. RESULTS A total of 21,560 patients were included: 11,237 (52%) implant-based (9791/87% immediate, 1446/13% delayed) and 10,323 (48%) autologous (8378/81% immediate, 1945/19% delayed). Complications occurred in 3666 (17%) patients (implant-based: n = 1112/11% immediate, n = 64/4.4% delayed cohorts; Autologous: n = 2073/25% immediate, n = 417/21% delayed cohorts). In propensity score weighting (PSW) analyses, immediate BR was associated with significantly more complications than delayed BR (p < 0.0001). This was the case for both implant-based and autologous BR, with a greater difference between the two time points noted in implant-based. Confounder-adjusted multivariable analyses confirmed these results. CONCLUSION At the 30-day time point, delayed BR is associated with significantly lower complication rates than immediate BR, in both the implant-based and autologous cohorts. These findings are not a blanket recommendation in favor of immediate and/or delayed BR. Instead, our insights may guide surgeons and patients in decision-making and help refine patients' eligibility in a case-by-case workup.

Contralateral internal mammary artery perforator flap for large inner chest wall defect repair and immediate breast reconstruction after excision of large malignant inner breast tumors. Microsurgery 2023; 43:809-817.

Abstract
OBJECTIVES Large breast tumor resection can cause chest wall defects that are difficult to close. A combination of oncoplastic techniques is required to repair chest wall defects and immediately reconstruct the breast. In this report, we present the use of the contralateral internal mammary artery perforator (IMAP) flap to repair large chest wall defects and perform breast reconstruction for a series of patients. METHODS Between July 2013 and June 2020, 10 patients and 4 patients underwent chest wall defect repair and breast reconstruction, respectively, with contralateral IMAP flaps. The average body mass index was 26.9 kg/m2 (range: 21.5-33.7 kg/m2 ). Tumor sizes varied from 2.5 × 1.5 × 0.8 to 9.5 × 6.0 × 4.0 cm3 . Defect sizes ranged from 16 × 10 to 8 × 4 cm2 . All patients underwent multiple imaging examinations to exclude abnormalities. Primary outcomes included complete tumor resection and flap survival. Secondary outcomes included the BREAST-Q results and bilateral breast symmetry measurements. RESULTS All flaps exhibited good postoperative survival and were between 20 × 12 and 10 × 5 cm2 . Two patients experienced minor complications that did not influence outcomes. No obvious donor site complications were observed. The BREAST-Q results indicated favorable reconstructive efficacy, with "satisfaction with breasts," "physical well-being (chest)," and "satisfaction with the outcome" scores of 77.8 (range: 58-87), 83.2 (range: 77-89), and 80.1 (range: 70-88), respectively. No signs of tumor recurrence were observed during a median follow-up period of 53.5 months (range: 6-83 months). However, poor postoperative bilateral breast symmetry was observed (vertical extent: 0.63 [range: 0.36-0.88]; horizontal extent: 0.64 [range: 0.41-0.80]). CONCLUSIONS IMAP flaps are reliable options for chest wall defect repair and breast reconstruction for selected patients with locally advanced breast cancer and inner breast tumors. Despite poor postoperative bilateral breast symmetry, most patients reported excellent outcomes.

Gluteal Propeller Perforator Flaps: A Paradigm Shift in Abdominoperineal Amputation Reconstruction. J Clin Med 2023; 12:4014. [PMID: 37373707 DOI: 10.3390/jcm12124014] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Revised: 05/25/2023] [Accepted: 06/05/2023] [Indexed: 06/29/2023] Open
Abstract
Abdominoperineal amputation (AAP) is a gold standard procedure treating advanced abdominal and pelvic cancers. The defect resulting from this extensive surgery must be reconstructed to avoid complications, such as infection, dehiscence, delayed healing, or even death. Several approaches can be chosen depending on the patient. Muscle-based reconstructions are a reliable solution but are responsible for additional morbidity for these fragile patients. We present and discuss our experience in AAP reconstruction using gluteal-artery-based propeller perforator flaps (G-PPF) in a case series. Between January 2017 and March 2021, 20 patients received G-PPF reconstruction in two centers. Either superior gluteal artery (SGAP)- or inferior artery (IGAP)-based perforator flaps were performed depending on the best configuration. Preoperative, intraoperative, and postoperative data were collected. A total of 23 G-PPF were performed-12 SGAP and 11 IGAP flaps. Final defect coverage was achieved in 100% of cases. Eleven patients experienced at least one complication (55%), amongst whom six patients (30%) had delayed healing, and three patients (15%) had at least one flap complication. One patient underwent a new surgery at 4 months for a perineal abscess under the flap, and three patients died from disease recurrence. Gluteal-artery-based propeller perforator flaps are an effective and modern surgical procedure for AAP reconstruction. Their mechanic properties, in addition to their low morbidity, make them an optimal technique for this purpose; however, technical skills are needed, and closer surveillance with patient compliance is critical to ensure success. G-PPF should be widely used in specialized centers and considered a modern alternative to muscle-based reconstructions.

Abstract
INTRODUCTION There remains an unclear definition of the term "gigantomastia," with many studies using different parameters and measurements. Currently, the operative management and patient education for gigantomastia are outdated. The historical teaching that a free nipple graft is necessary in elongated pedicles to avoid nipple necrosis may not be factual. The principal goal of our review aims to determine the safety of nipple-sparing breast reductions on large ptotic breasts via complication rate analysis. METHODS The systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines of conduct for systematic review and meta-analysis. In October 2021, PubMed was used to search the US National Library of Medicine database. Rayyan Intelligent Systematic Review aided in screening studies by title then abstract. If inclusion criteria were met, the entire article was reviewed. RESULTS Twenty-two articles satisfied the inclusion and exclusion criteria. The study was composed of 1689 total patients with a mean body mass index of 32.9 (±3.4). Mean midclavicle-to-nipple distance and resection weight per breast was 39 cm (±3.8) and 1423.8 g (±268.9), respectively. A Wise pattern was preferred in 77.3% of the studies, with an inferior (45.5%) and superomedial (45.5%) pedicle used most commonly. Complete nipple areolar complex necrosis (1.7%) was found in 4 studies, whereas partial (5.9%) was observed in 11. More common complications included delayed wound healing (17.4%), surgical site infection (14.3%), seroma (10.5%), scar hypertrophy (9.9%), and wound dehiscence (9.2%). CONCLUSION Nipple-sparing breast reduction surgery can be safely performed on hypertrophic and severely ptotic breasts with nipple areolar complications, such as partial or complete nipple areolar complex loss, at a rate less than previously believed.

Abstract
INTRODUCTION As the incidence of breast cancer and diabetes rises, so does the number of patients with diabetes undergoing breast reconstruction (BR). Patients with diabetes are at a higher risk for post-operative complications. The current study examined the effects of diabetes on BR wound outcomes and overall complications post-operatively. METHODS This study followed the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. We conducted a systematic search and meta-analysis for published articles on the effects of DM on BR in January 2022 using the PubMed, MEDLINE, and Cochrane databases. Diabetes, breast reconstruction, and complications were used as keywords. RESULTS Forty-three studies were included in the qualitative synthesis, and five provided data to be included in the meta-analysis published between 2006 and 2020. A total of 19,731 patients (9.07%) had diabetes, whereas 197,812 patients had no diabetes. The results of the pooled outcomes revealed no differences in the risk of total flap loss (p = 0.892) and wound infection (p = 0.579,). Nevertheless, the risk of wound dehiscence was significantly higher among patients with diabetes than their non-diabetic counterparts (p < 0.0001). CONCLUSION Diabetic patients undergoing BR have a significantly higher risk of wound dehiscence. As a result of the adverse effects of diabetes status on BR outcomes, patients need to be counseled about optimizing their diabetes management before surgery. Because of the heterogeneity in our results, prospective randomized studies are needed to shed light on the consequences of diabetes mellitus in BR surgeries.

Abstract
Indocyanine Green is a fluorescent substance visible in near-infrared light. It is useful for the identification of anatomical structures (biliary tract, ureters, parathyroid, thoracic duct), the tissues vascularization (anastomosis in colorectal, esophageal, gastric, bariatric surgery, for plasties and flaps in abdominal wall surgery, liver resection, in strangulated hernias and in intestinal ischemia), for tumor identification (liver, pancreas, adrenal glands, implants of peritoneal carcinomatosis, retroperitoneal tumors and lymphomas) and sentinel node identification and lymphatic mapping in malignant tumors (stomach, breast, colon, rectum, esophagus and skin cancer). The evidence is very encouraging, although standardization of its use and randomized studies with higher number of patients are required to obtain definitive conclusions on its use in general surgery. The aim of this literature review is to provide a guide for the use of ICG fluorescence in general surgery procedures.

Abstract
BACKGROUND Free flap autologous breast reconstruction (f-ABR) improves quality of life in cancer survivors but has a 5-47% higher postoperative complication (PCs) rate in vulnerable patients, such as those with obesity or the elderly. Given the high (respectively: 43% and 16%) and rising prevalence of these conditions, operative risk prediction is critical to guide targeted care. Age, BMI, and ASA class have shown inaccuracies as predictive factors of PCs in f-ABR. Since frailty, a measure of vulnerability, was reported to be a reliable predictor of PCs in multiple other surgical fields, we hypothesized that it would be an accurate predictor of PCs also in f-ABR. METHODS Patients undergoing f-ABR (CPT: 19364) were identified using the ACS-NSQIP (American College of Surgeons-National Surgical Quality Improvement Program) database (01/2010-12/2018). Frailty was calculated using the validated modified Frailty Index (mFI). Rates of wound complications, bleeding episodes, readmissions, returns to operating room (ROR), and DVTs were compared across mFI score, BMI, age, and ASA class. RESULTS mFI ≥ 2 was associated with 22.22% (p <0.001) wound complications; 15.79% (p <0.001) bleeding episodes; 8.20% (p <0.001) readmissions; 17.19% (p <0.001) ROR; and 1.81% (p <0.05) DVTs. Higher BMI, age, and ASA class did not significantly correlate with increased rates in one or more PCs. Only a high mFI was consistently associated with significantly higher odds of complications in all complication types. CONCLUSIONS As a reliable and accurate predictor of PCs in f-ABR, frailty could be used preoperatively to counsel patients and guide surgical care.

Patients with breast cancer undergoing mastectomy should be offered the option of immediate breast reconstruction (IBR). The aim of this retrospective study was to assess whether there is a delay in the initiation of adjuvant chemotherapy in patients undergoing mastectomy with or without IBR.
Method
The study included patients aged 70 years or younger with clinically node-negative breast cancer who underwent unilateral mastectomy with IBR (IBR group) or mastectomy alone (no-IBR group) followed by adjuvant chemotherapy at the Helsinki University Hospital between January 2012 to July 2018.
Results
A total of 645 patients were included; 186 in the IBR group and 459 in the no-IBR group. Sixty-six (35.5 per cent) patients in the IBR group and 102 (22.2 per cent) patients in the no-IBR group received their first chemotherapy cycle later than 6 weeks after surgery (P < 0.001). The respective numbers for later than 8 weeks were 17 (9.1 per cent) and 14 (3.1 per cent) (P = 0.001). Among all 645 patients, postoperative complications were a significant risk factor for a delay in the initiation of chemotherapy. Sixty-seven (39.9 per cent) patients with and 101 (21.2 per cent) patients without complications had a delay in chemotherapy (P < 0.001). The delay in chemotherapy was due to complications in 39 (59.1 per cent) in the IBR group and in 28 (27.5 per cent) in the no-IBR group (P < 0.001).
Conclusion
Patients undergoing mastectomy alone were more likely to receive adjuvant chemotherapy within 6 weeks after surgery compared with the IBR patients. IBR significantly increased the risk of postoperative complications in comparison with mastectomy alone. The complications, in turn, were a significant risk factor for delay in adjuvant chemotherapy.

Abstract
OBJECTIVE This study aims to generate a reproducible and generalizable Workflow model of ICG-angiography integrating Standardization and Quantification (WISQ) that can be applied uniformly within the surgical innovation realm independent of the user. SUMMARY BACKGROUND DATA Tissue perfusion based on indocyanine green (ICG)-angiography is a rapidly growing application in surgical innovation. Interpretation of have been subjective and error-prone due to the lack of a standardized and quantitative ICG-workflow and analytical methodology. There is a clinical need for a more generic, reproducible, and quantitative ICG perfusion model for objective assessment of tissue perfusion. METHODS In this multicenter, proof-of-concept study, we present a generic and reproducible ICG-workflow integrating standardization and quantification for perfusion assessment. To evaluate our model's clinical feasibility and reproducibility, we assessed the viability of parathyroid glands after performing thyroidectomy. Biochemical hypoparathyroidism was used as the postoperative endpoint and its correlation with ICG quantification intraoperatively. Parathyroid gland are an ideal model as parathyroid function post-surgery is only affected by perfusion. RESULTS We show that visual -subjective- interpretation of ICG-angiography by experienced surgeons on parathyroid perfusion cannot reliably predict organ function impairment postoperatively, emphasizing the importance of an ICG quantification model. WISQ was able to standardize and quantify ICG-angiography and provided a robust and reproducible perfusion curve analysis. A low ingress slope of the perfusion curve combined with a compromised egress slope was indicative for parathyroid organ dysfunction in 100% of the cases. CONCLUSION WISQ needs prospective validation in larger series and may eventually support clinical decision-making to predict and prevent postoperative organ function impairment in a large and varied surgical population.

Abstract
INTRODUCTION Indocyanine Green Angiography (ICG-A) is an imaging technique used to visualize tissue perfusion in real time. The aim of this systematic review and meta-analysis is to evaluate all published papers on breast reconstruction using ICG-A, which provides information on complication rates and to investigate whether the use of this peroperative method decreases the risk of complications. MATERIALS AND METHODS MEDLINE/PubMed, EMBASE, Cochrane, and UpToDate were searched using relevant terms. The literature was assessed using the PRISMA guidelines. Inclusion criteria were: original articles written in English assessing ICG-angiography in breast reconstruction. The individual studies were evaluated according to Cochrane guidelines. RESULTS The search yielded 243 papers on ICG-A and breast reconstruction. Twenty-six of these were included for analysis. The risk of overall major complications ([OR] = 0.53, 95% confidence interval (CI) = 0.43-0.66, p = 0.00001) and overall loss of reconstruction ([OR] = 0.58, 95% CI = 0.37-0.92, and p = 0.020) was significantly lower when peroperative ICG-A was used. When using ICG-A to evaluate mastectomy flaps, a statistically lower risk of major complications ([OR] = 0.56 and p = 0.0001) and the loss of reconstruction was found ([OR] = 0.46, p = 0.006). ICG-A used in autologous breast reconstruction significantly reduced the risk of minor ([OR] = 0.62 and p = 0.001) and major complications ([OR] = 0.53 and p = 0.0028). CONCLUSIONS This is the first systematic review to analyze the use of ICG-A on both mastectomy flaps and autologous reconstruction. The results obtained in the current study indicate that the use of ICG-A in breast reconstructive procedures reduces the complications as well as the loss of reconstruction.

Abstract
Indocyanine green (ICG) angiography is a procedure that uses a fluorescent dye for a variety of medical diagnostics, including the real-time examination of blood flow in tissue. Herein, we report a case in which ICG angiography was used to assess the viability of a sternocleidomastoid (SCM) muscle flap during post-parotidectomy facial reconstruction. To our knowledge, this is the first report documenting the intraoperative use of ICG for the evaluation of SCM flap perfusion. ICG angiography may prove beneficial for cases involving complex reconstructions and suspected organ hypoperfusion.

Predicting the Feasibility of Utilizing SIEA Flap for Breast Reconstruction with Preoperative BMI and Computed Tomography Angiography (CTA) Data. Aesthetic Plast Surg 2021; 45:100-107. [PMID: 31919624 DOI: 10.1007/s00266-019-01605-0] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2019] [Accepted: 12/27/2019] [Indexed: 10/25/2022]
Abstract
BACKGROUND Diameters greater than 1.5 mm are considered one of the generally accepted criteria for utilizing superficial epigastric artery (SIEA) flaps for breast reconstruction. However, this standard fails to consider individual differences among patients or deep inferior epigastric perforator (DIEP) perfusion of the same angiosome as the SIEA. This study combined the SIEA system with the DIEP system and explored the relationship between the two systems and body mass index (BMI) to theoretically provide a reference for flap choice in the preoperative surgical plan. METHODS This study analysed preoperative computed tomography angiography (CTA) data from patients who received systematically postoperative treatment for unilateral breast cancer and were scheduled for breast reconstruction from 2013 to 2018 in our centre. All patients included had no past medical history that might have influenced the diameter of the SIEA, and their CTA data showed the presence of SIEA. RESULTS Twenty-five females with a mean BMI of 23.6 ± 3.3 kg/m2 were included. A total of 30 hemi-abdomens identified with the SIEA were assessed. The measured mean diameter of the SIEA was 1.63 ± 0.55 mm, showing a highly linear correlation with BMI (r = 0.73, p < 0.001), while the maximum diameter of the deep inferior epigastric perforator (DIEPmax) and the number of dominant perforators originating from the deep inferior epigastric artery (DIEA) were not related to BMI. It was analysed from the equation between the calibre of the SIEA and BMI that when the BMI was greater than or equal to 24 kg/m2, the minimum diameter of the SIEA was at least 1.5 mm; when the BMI was 25 kg/m2, the diameter of the SIEA was, at most, 2.0 mm. Based on the linear correlation described above, we proposed that if the diameter of the SIEA was greater than or equal to 2.0 mm, a BMI ≥ 25 kg/m2 could be fully guaranteed. In terms of the advantageous single pedicle for reconstruction, the ratio of the SIEA diameter to DIEPmax (SIEA/DIEPmax) showed a significant linear correlation with BMI (r = 0.82, p < 0.001), and when the BMI was greater than or equal to 25 kg/m2, the lower limit of its predicted value was above 1.0; in other words, the SIEA diameter was advantageous compared with DIEPmax for the use of a single pedicle. In terms of perfusion, the SIEA system was positively correlated with BMI (p < 0.001), while the DIEP system was not. The difference in perfusion level between the SIEA and DIEP systems showed a positive correlation with BMI (p = 0.001), while the sum of the two systems only tended to be correlated, without statistical significance (p = 0.06). CONCLUSIONS For patients with a BMI ≥ 25 kg/m2 or an SIEA diameter ≥ 2.0 mm, application of an SIEA flap is theoretically a preferable choice in preoperative surgical planning for breast reconstruction. And the patients should meet two conditions: the first one is the absence of past medical history that might potentially influence the diameter of the SIEA; the second is the presence of the SIEA, which has already been shown by the preoperative imaging data. Through perfusion-related studies, we propose that the SIEA is likely a compensatory vessel that is inclined to present in people with larger BMIs.

Thoracodorsal artery flaps for breast reconstruction-the variants and its approach. Arch Plast Surg 2021; 48:15-25.

Abstract
Thoracodorsal artery (TDA) flaps, ranging from the vascular-pedicled thoracodorsal artery perforator (TDAP) flap, the propeller TDAP flap, and the muscle-sparing latissimus dorsi (MSLD) flap to the conventional latissimus dorsi (LD) flap and the extended LD flap, can all be used for breast reconstruction. The aim of this paper and review is to share our experiences and recommendations for procedure selection when applying TDA-based flaps for breast reconstruction. We describe the different surgical techniques and our thoughts and experience regarding indications and selection between these procedures for individual patients who opt for breast reconstruction. We have performed 574 TDA flaps in 491 patients: 60 extended LD flaps, 122 conventional LD flaps, two MSLD flaps, 233 propeller TDAP flaps, 122 TDAP flaps, and 35 free contralateral TDAP flaps for stacked TDAP breast reconstruction. All the TDA flaps are important flaps for reconstruction of the breast. The LD flap is still an option, although we prefer flaps without muscle when possible. The vascular-pedicled TDAP flap is an option for experienced surgeons, and the propeller TDAP flap can be used in most reconstructive cases of the breast, although a secondary procedure is often necessary for correction of the pedicle bulk. The extended LD flap is an option for women with a substantial body mass index, although it is associated with the highest morbidity of all the TDA flaps. The MSLD flap can be used if the perforators are small or if dissection of the perforators is assessed to be hazardous.

Abstract
With the rise of fluorescence-guided surgery, it has become evident that different types of fluorescence signals can provide value in the surgical setting. Hereby a different range of targets have been pursued in a great variety of surgical indications. One of the future challenges lies in combining complementary fluorescent readouts during one and the same surgical procedure, so-called multi-wavelength fluorescence guidance. In this review we summarize the current clinical state-of-the-art in multi-wavelength fluorescence guidance, basic technical concepts, possible future extensions of existing clinical indications and impact that the technology can bring to clinical care.

Abstract
BACKGROUND Breast cancer will affect one in eight women during their lifetime. The opportunity to restore the removed tissue and cosmetic appearance is provided by reconstructive breast surgery following skin-sparing mastectomy (SSM). Mastectomy skin flap necrosis (MSFN) is a common complication following SSM breast reconstruction. This postoperative complication can be prevented by intraoperative assessment of mastectomy skin flap viability and intervention when tissue perfusion is compromised. Indocyanine green fluorescence angiography is presumed to be a better predictor of MSFN compared to clinical evaluation alone. OBJECTIVES To assess the effects of indocyanine green fluorescence angiography (ICGA) for preventing mastectomy skin flap necrosis in women undergoing immediate breast reconstruction following skin-sparing mastectomy. To summarise the different ICGA protocols available for assessment of mastectomy skin flap perfusion in women undergoing immediate breast reconstructions following skin-sparing mastectomy. SEARCH METHODS We searched the Cochrane Breast Cancer Specialised Register, Cochrane Central Register of Controlled Trials (CENTRAL; Issue 3, 2019), MEDLINE, Embase, the World Health Organization's International Clinical Trials Registry Platform (ICTRP) and Clinicaltrials.gov in April 2019. In addition, we searched reference lists of published studies. SELECTION CRITERIA We included studies that compared the use of ICGA to clinical evaluation to assess mastectomy skin vascularisation and recruited women undergoing immediate autologous or prosthetic reconstructive surgery following SSM for confirmed breast malignancy or high risk of developing breast cancer. DATA COLLECTION AND ANALYSIS Two review authors independently assessed the risk of bias of the included nonrandomised studies and extracted data on postoperative outcomes, including postoperative MSFN, reoperation, autologous flap necrosis, dehiscence, infection, haematoma and seroma, and patient-related outcomes. The quality of the evidence was assessed using the GRADE approach and we constructed two 'Summary of finding's tables: one for the comparison of ICGA to clinical evaluation on a per patient basis and one on a per breast basis. MAIN RESULTS Nine nonrandomised cohort studies met the inclusion criteria and involved a total of 1589 women with 2199 breast reconstructions. We included seven retrospective and two prospective cohort studies. Six studies reported the number of MSFN on a per breast basis for a total of 1435 breasts and three studies reported the number of MSFN on a per patient basis for a total of 573 women. Five studies reported the number of other complications on a per breast basis for a total of 1370 breasts and four studies reported the number on a per patient basis for a total of 613 patients. Therefore, we decided to pool data separately. Risk of bias for each included nonrandomised study was assessed using the Newcastle-Ottawa Scale for cohort studies. There was serious concern with risk of bias due to the nonrandomised study design of all included studies and the low comparability of cohorts in most studies. The quality of the evidence was found to be very low, after downgrading the quality of evidence twice for imprecision based on the small sample sizes and low number of events in the included studies. Postoperative complications on a per patient basis We are uncertain about the effect of ICGA on MSFN (RR 0.79, 95% CI 0.40 to 1.56; three studies, 573 participants: very low quality of evidence), infection rates (RR 0.91, 95% CI 0.60 to 1.40; four studies, 613 participants: very low quality of evidence), haematoma rates (RR 0.87, 95% CI 0.30 to 2.53; two studies, 459 participants: very low quality of evidence) and seroma rates (RR 1.68, 95% CI 0.41 to 6.80; two studies, 408 participants: very low quality of evidence) compared to the clinical group. We found evidence that ICGA may reduce reoperation rates (RR 0.50, 95% CI 0.35 to 0.72; four studies, 613 participants: very low quality of evidence). One study considered dehiscence as an outcome. In this single study, dehiscence was observed in 2.2% of participants (4/184) in the ICGA group compared to 0.5% of participants (1/184) in the clinical group (P = 0.372). The RR was 4.00 (95% CI 0.45 to 35.45; one study; 368 participants; very low quality of evidence). Postoperative complications on a per breast basis We found evidence that ICGA may reduce MSFN (RR 0.62, 95% CI 0.48 to 0.82; six studies, 1435 breasts: very low quality of evidence), may reduce reoperation rates (RR 0.65, 95% CI 0.47 to 0.92; five studies, 1370 breasts: very low quality of evidence) and may reduce infection rates (RR 0.65, 95% CI 0.44 to 0.97; five studies, 1370 breasts: very low quality of evidence) compared to the clinical group. We are uncertain about the effect of ICGA on haematoma rates (RR 1.53, CI 95% 0.47 to 4.95; four studies, 1042 breasts: very low quality of evidence) and seroma rates (RR 0.71, 95% CI 0.37 to 1.35; two studies, 528 breasts: very low quality of evidence). None of the studies reported patient-related outcomes. ICGA protocols: eight studies used the SPY System and one study used the Photodynamic Eye imaging system (PDE) to assess MSFN. ICGA protocols in the included studies were not extensively described in most studies. AUTHORS' CONCLUSIONS Although mastectomy skin flap perfusion is performed more frequently using ICGA as a helpful tool, there is a lack of high-quality evidence in the context of randomised controlled trials. The quality of evidence in this review is very low, since only nonrandomised cohort studies have been included. With the results from this review, no conclusions can be drawn about what method of assessment is best to use during breast reconstructive surgery. High-quality randomised controlled studies that compare the use of ICGA to assess MSFN compared to clinical evaluation are needed.

Abstract
BACKGROUND Skin flap necrosis (SFN) is a morbid complication that is disfiguring, leads to acute and chronic wound issues, often requires further surgery, and can delay adjuvant chemotherapy. Although most surgeons rely on the clinical examination, near-infrared (NIR) spectroscopy can extrapolate tissue oxygenation and may serve as an important tool to assess flap perfusion intraoperatively. This cohort study was undertaken to evaluate the capacity of NIR spectroscopy to detect clinically relevant differences in tissue perfusion intraoperatively. METHODS Patients undergoing oncologic resection of breast cancer, sarcomas, and cutaneous tumors requiring flap reconstruction (local, regional, or free) between January 2018 and January 2019 were analyzed in this study. Clinicians were blinded to device tissue oxygen saturation (StO2) measurements taken intraoperatively after closure and at follow-up appointments in the first 30 days. Measurements were categorized as (1) control areas not affected by the procedure, (2) areas at risk, and (3) areas of necrosis. These areas were retrospectively demarcated by 2 blinded assessors on follow-up images and transposed onto anatomically correlated intraoperative StO2 measurements. Mean StO2 values were compared using a single-sample t test and analysis of variance (ANOVA) to determine differences in oxygenation. RESULTS Forty-two patients were enrolled, and 51 images were included in the analysis. Oncologic procedures were predominantly breast (22), postextirpative melanoma (13), and sarcoma (3) reconstructions. Flap reconstruction involved 30 regional skin flaps, 3 pedicled flaps, and 3 free flaps. Nine patients (20.9%) and 11 surgical sites developed SFN. Mean intraoperative StO2 measurements for control areas, areas at risk, and areas of SFN were 74.9%, 71.1%, and 58.3%, respectively. Relative to control areas, mean intraoperative StO2 measurements were lower by 17.5% (P = 0.01) in ultimate areas of SFN and in areas at risk by 5.8% (P = 0.003). Relative to areas at risk, mean StO2 measurements from areas of ultimate SFN were lower by 8.3% (P = 0.04). CONCLUSION These preliminary data suggest that measuring skin flap tissue oxygenation intraoperatively, with NIR spectroscopy, can differentiate objective variations in perfusion that are associated with clinical outcomes.

Abstract
Supplemental Digital Content is available in the text. During reconstructive breast surgery, intraoperative assessment of tissue perfusion has been solely based on subjective clinical judgment. However, in the last decade, intraoperative indocyanine green angiography (ICGA) has become an influential tool to visualize blood flow to the tissue of interest. This angiography technique produces real-time blood flow information to provide an objective assessment of tissue perfusion.

Abstract
Laser-assisted indocyanine green angiography allows surgeons to determine intraoperative flap perfusion and achieve the best outcomes in breast reconstruction. This study stratified outcomes based on a meta-analysis of complications including longitudinal trials comparing the clinical assessment of skin flaps during breast reconstruction. Nine studies met inclusion criteria and reported outcomes of interest (n = 2256). The risk of flap necrosis and the necessity of reoperation was statistically significantly higher in the control group.

Abstract
BACKGROUND Indocyanine green fluorescence angiography (ICGA) is a new adjunct that has been used in surgical procedures to assess blood flow. This study evaluated the utility of ICGA compared to visual inspection to predict parathyroid function, guide autotransplantation and potentially decrease permanent hypoparathyroidism. METHODS This was a retrospective study of patients who underwent total or near-total thyroidectomy (T-NT) between January 2015 and March 2018. Patients with preoperative hyperparathyroidism and those undergoing reoperation were excluded. Patients who had ICGA were compared to T-NT patients without ICGA. Data were analyzed to assess the frequency of autotransplantation and incidence of hypoparathyroidism between groups. RESULTS In total, 210 patients underwent T-NT: 86 with ICGA and 124 without. Autotransplantation was more common in the ICGA group at 36% compared to 12% in the control (p = 0.0001). There was no correlation with at least one normal parathyroid gland on ICGA and postoperative PTH levels (p = 0.75). There was a difference in having normal postoperative PTH when there were at least two normal parathyroid glands (n = 50) compared to patients with less than two normal ICGA glands (n = 36, p = 0.044). Visual assessment and ICGA assessment of vascularity were in agreement, 245/281 (87%). There were 19 glands (6.8%) that would have undergone autotransplant based on visual inspection that had adequate blood supply on ICGA. Transient hypoparathyroidism was present in 45 out of 124 controls (36%) and 32 out of 86 (37%) in the ICG group. CONCLUSIONS ICGA is a novel technique that may improve the assessment of parathyroid gland blood supply compared to visual inspection. ICGA can guide more appropriate autotransplantation without compromising postoperative parathyroid function. At least two vascularized glands on ICGA may predict postoperative parathyroid gland function.

Abstract
Today, breast cancer is treated, and breast reconstruction is performed in specialized centers. Integrated surgical, oncological and reconstructive treatment and care should characterize the comprehensive pathway. In this setting, the women being diagnosed with breast cancer or genetic disposition thereto, should be offered the highest standard of care and treatment. The prerequisite for a successful reconstruction as well as timely onset of adjuvant treatment is uneventful healing. In addition, this may also yield an aesthetically acceptable or even pleasing result. When performing a breast reconstruction or oncoplasty, adequate viability of the tissues left behind and/or added to partially or totally reconstruct the breast, is of utmost importance for a successful outcome. Therefore, tools to assess tissue perfusion are excellent and valuable instruments for the breast reconstructive surgeon. Indocyanine green-angiography (ICG-A) has been shown to be beneficial in delayed and immediate breast reconstruction. The absolute prerequisite for a successful immediate reconstruction is the nipple-sparing or subcutaneous mastectomy using a sufficient incision to spare the perfusion of the native skin. Upon completion of the mastectomy perfusion assessment is performed and the breast reconstructed, using implants or expanders with or without acellular dermal matrix or autologous flaps. The perfusion of the autologous flap may also be assessed using ICG-A. Depending on the assessment score, the mastectomy flaps or the autologous flap are subsequently revised, thereby increasing the probability of saving the patient post-operative revision and take-back to surgery and thus ensuring uneventful healing.

Abstract
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.

Abstract
Background. Indocyanine green angiography (ICGA) offers the potential to provide objective data for evaluating tissue perfusion of flaps and reduce the incidence of postoperative necrosis. Consensus on ICGA protocols and information on factors that have an influence on fluorescence intensity is lacking. The aim of this article is to provide a comprehensive insight of in vivo and ex vivo evaluation of factors influencing the fluorescence intensity when using ICGA during reconstructive flap surgery. Methods. A systematic literature search was conducted to provide a comprehensive overview of currently used ICGA protocols in reconstructive flap surgery. Additionally, ex vivo experiments were performed to further investigate the practical influence of potentially relevant factors. Results. Factors that are considered important in ICGA protocols, as well as factors that might influence fluorescence intensity are scarcely reported. The ex vivo experiments demonstrated that fluorescence intensity was significantly related to dose, working distance, angle, penetration depth, and ambient light. Conclusions. This study identified factors that significantly influence the fluorescence intensity of ICGA. Applying a weight-adjusted ICG dose seems preferable over a fixed dose, recommended working distances are advocated, and the imaging head during ICGA should be positioned in an angle of 60° to 90° without significantly influencing the fluorescence intensity. All of these factors should be considered and reported when using ICGA for tissue perfusion assessment during reconstructive flap surgery.

J Plast Reconstr Aesthet Surg 2019; 72:1150-1156.

Abstract
BACKGROUND Indocyanine green angiography (ICGA) is slowly replacing conventional methods of evaluating perfusion during flap surgery. Microcirculatory changes during flap elevation create a marked state of hypoperfusion intraoperatively leading to ICGA underestimation of tissue viability and consequent resection of viable tissue. We propose a novel method of flap warming to induce maximum vasodilation before performing ICGA to increase accuracy in assessing perfusion. METHODS Submental flaps harvested on a single perforator were created in 8 pigs. ICG angiography was performed in the intraoperative phase (ICGA-C), after inducing maximum vasodilatation by warming the flap at 42 °C (ICGA-W) and at 24H postoperative (ICGA-24). By setting a fluorescence threshold of 33% as indicative of necrosis, the flap surface deemed viable by ICGA was measured for ICGAC, ICGAW and ICGA24. The results were then compared to the actual flap survival observed clinically at 7 days. RESULTS The mean of ICG-C predicted flap survival (FS-C = 49.17%) is 12.97% lower than the mean of actual flap survival on postoperative day 7 (FS = 62.14%). The mean difference between ICG-W and ICG-24 predicted flap survival (FS-W and FS-24) and actual flap survival in the postoperative day 7 (FS) is lower, 3.13% and 2.15%, respectively. Average perfusion recovery over 24 h was 10.83% (FS-24-FS-C). CONCLUSIONS Conventional intraoperative ICGA underestimated perfusion in all cases. Warming the flap intraoperatively and achieving maximum vasodilation mitigates the effects of vasoconstriction and mimics the microcirculatory environment encountered at 24 h. Performing angiography after induced vasodilation improves ICGA assessment of flap perfusion.
