Material and methods This study was conducted as an anonymous online cross-sectional survey. Only students who have completed a microsurgical training course at our department within a ten years period between 2013 and 2023 were eligible for this online survey. This survey aimed to analyze the subjective microsurgical skills at the time of the survey and the influence of the course on further career decisions and development.

This systematic review evaluates existing literature on these minimally invasive techniques, focusing on their potential applications in preventing ischemia-related complications. Methods A systematic review was conducted in July 2024 using PubMed, MEDLINE, and Web of Science following Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Inclusion criteria were studies that included patients undergoing any flap-based reconstruction treated with minimally invasive delay. Exclusion criteria were non-English papers, other systematic reviews, nonhuman patients, and pediatric patients. Results Six studies were included (angiographic delay n=143, heat preconditioning n=191, ischemic preconditioning n=60) which examined minimally invasive methods for perfusion optimization. Aggregated data from the three studies on angiographic delay demonstrated a 13% (18/143) combined skin or fat flap necrosis rate, which was lower than that of non-delayed flaps and comparable to more invasive traditional surgical ligation. Ischemic preconditioning showed no significant differences (p=1.0) g compared to controls, whereas heat preconditioning led to reductions (26% vs. 35%) in flap necrosis and necrosis requiring surgical intervention (11% vs. 17%). Conclusion Angiographic embolization presents a promising alternative to invasive surgical delay, effectively reducing flap necrosis risk. Heat and ischemic preconditioning also show potential for increasing flap survival, although current studies are limited by small sample sizes. Further research is essential to explore preoperative conditioning interventions to improve surgical outcomes for patients who require less invasive delay techniques.</p>","PeriodicalId":16949,"journal":{"name":"Journal of reconstructive microsurgery","volume":" ","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-02-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143441198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Less commonly used abdominal flaps include the superficial inferior epigastric artery (SIEA) and the superficial circumflex iliac artery (SCIA) flaps which are based on the superficial vasculature of the abdominal wall. We sought to compare complication rates between DIEP and superficial system flaps and their associated risk factors. Methods A retrospective chart review of 400 breast cancer patients undergoing abdominally-based free flap breast reconstruction with either a DIEP or superficial flap from January 2017 to December 2023 was performed at a single institution. The primary outcome was breast and abdominal site complications. Results A total of 638 flaps, 571 (89.4%) DIEP and 67 (10.5%) superficial, were performed with flap complication rates of 27.3% and 22.4% respectively. At the recipient site, there was a significant difference in the rate of postoperative thrombosis (0.7% vs. 4.5%, p=0.015); however, there were no differences for flap failure (0.4% vs. 1.5%, p=0.28) or other flap complications.

Although not statistically significant, abdominal bulging was seen in 18 DIEP flap patients compared to none observed in the superficial flap patients (p=0.24). When controlling for age, BMI, and radiation history, the overall rate of superficial flap and abdominal complications was not statistically significant from the rate of DIEP flap complications (p=0.576). Conclusion Compared to DIEP flaps, superficial flaps had significantly higher rates of immediate perioperative thrombosis. However, there were no significant differences in rates of flap failure or other flap complications with superficial flaps compared to DIEP flaps. There was a clinically significant trend toward increased abdominal bulging with the use of DIEP flaps.
