Background/Objectives: Immortality and anti-aging research is accelerating, with implications across medicine. This narrative review explores the biological principles, translational innovations, and ethical considerations at the intersection of aging and plastic surgery, reframed for a broad clinical audience. Methods: A narrative review of the literature from PubMed, clinical trials, and translational studies was conducted, with emphasis on regenerative medicine, stem cells, tissue engineering, gene editing, and longevity pharmacologics within the field of plastic and reconstructive surgery. Results: Key themes include (1) the biology of aging and epigenetic reprogramming, (2) esthetic and regenerative innovations with broader clinical significance, (3) emerging genetic and pharmacologic longevity strategies, (4) ethical and regulatory challenges, and (5) future directions such as nanotechnology, artificial intelligence, and digital immortality. Conclusions: Immortality remains an aspirational frontier, but innovations in regenerative science and longevity research offer opportunities for improving healthspans. Medicine as a whole must balance innovation with ethics, equity, and safety in translating these discoveries to patient care.

AbstractBackgroundRecent CMS billing changes have raised concerns about insurance coverage for deep inferior epigastric perforator (DIEP) flap breast reconstruction. This study compared the costs and utilization of transverse rectus abdominis myocutaneous (TRAM), DIEP, and latissimus dorsi (LD) flaps in breast reconstruction.MethodThe study utilized the National Inpatient Sample database to identify female patients who underwent DIEP, TRAM, and LD flap procedures from 2016 to 2019. Key data such as patient demographics, length of stay, complications, and costs (adjusted to 2021 USD) were analyzed, focusing on differences across the flap types.ResultsA total of 17,770 weighted patient encounters were identified, with the median age being 51. The majority underwent DIEP flaps (73.5%), followed by TRAM (14.2%) and LD (12.1%) flaps. The findings revealed that DIEP and TRAM flaps had a similar length of stay (LOS), while LD flaps typically had a shorter LOS. The total hospital charges to costs using cost‐to‐charge ratio were also comparable between DIEP and TRAM flaps, whereas LD flaps were significantly less expensive. Factors such as income quartile, primary payer of hospitalization, and geographic region significantly influenced flap choice.ConclusionThe study's results appear to contradict the prevailing notion that TRAM flaps are more cost‐effective than DIEP flaps. The total hospital charges to costs using cost‐to‐charge ratio and hospital stays associated with TRAM and DIEP flaps were found to be similar. These findings suggest that changes in the insurance landscape, which may limit the use of DIEP flaps, could undermine patient autonomy while not necessarily reducing healthcare costs. Such policy shifts could favor less costly options like the LD flap, potentially altering the landscape of microvascular breast reconstruction.

Abstract Quantifying lymph nodes in vascularized lymph node transfer (VLNT) has been performed using preoperative percutaneous ultrasound. The higher resolution and accuracy of intraoperative ultrasound (IOUS) over transcutaneous ultrasound has been demonstrated in the radiology literature for the identification and characterization of finer structures including hepatic lesions, pancreatic lesions, and biliary or pancreatic ducts. We hypothesize that IOUS during VLNT would be a superior method to quantify and map lymph nodes in our flaps. A prospectively collected database of patients undergoing VLNT over 3 years (October 2014 to October 2017) was reviewed. Patients who underwent IOUS during flap harvest, before pedicle ligation to simultaneously map and quantify the number of lymph nodes were included in the study. Twenty-one patients with an average age of 58.7 years and a mean BMI of 32.3 underwent VLNT with IOUS for chronic lymphedema during the study period. Extremity lymphedema was classified as Campisi IB (n = 7), IIA (n = 7), IIB (n = 5), and IIIA (n = 2). There were 14 superficial circumflex iliac artery flaps, including 4 performed concomitantly with a deep inferior epigastric perforator flap, 1 transverse cervical artery flap, and 6 omental flaps. The average number of lymph nodes transferred per IOUS was 4.3 for superficial circumflex iliac artery flaps, 4 for the transverse cervical artery flap, and 5.2 for the omental flaps. Intraoperative ultrasound allows the lymphatic surgeon to precisely map the location of lymph nodes which can guide intraoperative decision making. As there is no data correlating the number of lymph nodes transferred and outcomes after VLNT, developing a precise intraoperative quantification method is important.
