Management of Plastic Surgery Complications at a Tertiary Medical Center after Aesthetic Procedures.

The aesthetic plastic surgery industry has seen tremendous growth, with Americans spending an estimated 20 billion dollars on procedures in 2020. However, the effect of complications from these procedures on the healthcare system is poorly understood. This study aims to create awareness regarding aesthetic procedure complications through the scope of plastic surgeons at a tertiary medical facility. A retrospective chart review was performed on patients who received care at a single academic tertiary referral center over 5 years for complications from a cash-paid aesthetic procedure at an outside facility. Physician and hospital billing data were analyzed for relevant encounters. Patients in this study (n = 40) presented to the emergency department most frequently with complications secondary to abdominoplasty (35%), breast augmentation (27.5%), and injectable fillers (17.5%). The most common complications were infection (32.5%) and wound dehiscence (22.5%). Of those evaluated, 50% required inpatient admission. Additionally, 42.5% required surgical intervention. The distribution of payors included Medicaid (55%), commercial insurance (30%), and Medicare (7.5%), and 7.5% were uninsured. For physician billing, the total gross collection ratio was 21.3%, whereas the hospital billing total gross collection ratio was 25.16%. Larger referral hospitals are well-suited to support the aesthetic community with complication management; however, the care required to serve this population is resource-intensive. These data advocate for thorough closed-loop patient-surgeon communication regarding risk-benefit analysis and detailed courses of action should complications arise. Likewise, stronger communication between ambulatory surgical centers and tertiary referral centers may also help minimize complications and subsequent healthcare needs.

Advancing indocyanine green fluorescence flap perfusion assessment via near infrared signal quantification

IntroductionIntraoperative indocyanine green fluorescence angiography (ICGFA) perfusion assessment has been demonstrated to reduce complications in reconstructive surgery. This study sought to advance ICGFA flap perfusion assessment via quantification methodologies. MethodPatients undergoing pedicled and free flap reconstruction were subjected to intraoperative ICGFA flap perfusion assessment using either an open or endoscopic system. Patient demographics, clinical impact of ICGFA and outcomes were documented. From the ICGFA recordings, fluorescence signal quality, as well as inflow/outflow milestones for the flap and surrounding (control) tissue were computationally quantified post hoc and compared on a region of interest (ROI) level. Further software development intended full flap quantification, metric computation and heatmap generation. ResultsFifteen patients underwent ICGFA assessment at reconstruction (8 head and neck, 6 breast and 1 perineum) including 10 free and 5 pedicled flaps. Visual ICGFA interpretation altered on-table management in 33.3% of cases, with flap edges trimmed in 4 and a re-anastomosis in 1 patient. One patient suffered post-operative flap dehiscence. Laparoscopic camera use proved feasible but recorded a lower quality signal than the open system.Using established and novel metrics, objective ICGFA signal ROI quantification permitted perfusion comparisons between the flap and surrounding tissue. Full flap assessment feasibility was demonstrated by computing all pixels and subsequent outputs summarisation as heatmaps. ConclusionThis trial demonstrated the feasibility and potential for ICGFA with operator based and quantitative flap perfusion assessment across several reconstructive applications. Further development and implementation of these computational methods requires technique and device standardisation.

Abstract PO3-02-14: The Safety of Breast Reconstruction: The Impact of Breast Reconstruction Surgery on Postoperative Adjuvant Therapy for Breast Cancer

Abstract Background: Postoperative adjuvant therapy is very important in treating breast cancer, and increasing numbers of patients are undergoing immediate breast reconstruction (IBR) at the same time as breast cancer surgery. However, the impact of breast reconstruction surgery on adjuvant therapy is controversial. In this multicenter cohort study led by the Japanese Breast Cancer Society, we examined the impact of reconstructive surgery on postoperative adjuvant therapy in breast cancer patients who underwent IBR. Methods: We examined the association between adjuvant therapy and complications of reconstructive surgery in 4726 patients with primary breast cancer who underwent IBR during the period from January 1, 2008 to December 31, 2016. Statistical analysis employed the χ2 test. Results: Of the 995 patients who received adjuvant chemotherapy, the median time from the date of surgery to the start of chemotherapy was 51.0 days, with 63 patients (6.2%) starting more than 90 days after surgery. Eighty-four IBR complications required surgery (8.4%), including infections and tissue expander (TE) removal. Of the 63 patients for whom chemotherapy was initiated 90 days or more after surgery, 10 patients (15.9%) had complications requiring surgery, significantly more than the 74 patients (7.9%) in the < 90 days group (P = 0.028). Post-mastectomy radiation therapy (PMRT) was performed after breast cancer surgery in 359 cases: 69 cases received autologous tissue irradiation, 46 TE irradiation, 241 silicone breast implant (SBI) irradiation, and 3 artificial material removal before irradiation. 5 cases given autologous tissue irradiation and 26 receiving artificial material irradiation (22 of whom the artificial material was removes) required surgery within 1 year after the cancer surgery due to complications of IBR. There was no significant difference in the frequency of complications requiring surgery between autologous tissue irradiation and artificial material irradiation (P=0.632). There were 33 complications (9.2%) requiring surgery in the irradiated group, significantly more than the 129 cases (3.0%) in the non-irradiated group (P< 0.001). Conclusion: Adjuvant chemotherapy was generally not delayed, but complications requiring surgery related to IBR were more frequent in those with delay beyond 90 days, suggesting that postoperative complications from breast reconstruction may have influenced the delay in initiating chemotherapy. Therefore, in cases for whom postoperative chemotherapy is anticipated, complications from breast reconstruction may have impacted outcomes, making preoperative risk assessment even more important. There was no difference in the frequency of reconstructive complication surgery according to whether autologous tissue irradiation or artificial material irradiation had been used, but further investigation is needed.

Plastik Cerrahide Yaşın Ameliyat Sonrası Sonuçlara Etkisi: Veri Analizi ve Çıkarımlar

Abstract: Aim: To investigate the effect of advancing age on postoperative outcomes in plastic surgery, focusing on patients aged 60 years and above. Methods: A retrospective analysis of clinic data from January 1, 2020, to October 1, 2023, was conducted. Data included patient demographics, preoperative comorbidities, surgical details, and 30-day postoperative complications. Logistic regression models were employed to evaluate the association between age and complication rates, adjusting for confounders like comorbidities and surgery types. Results: The study found a significant association between increasing age and higher complication rates within 30 days post-surgery. It also revealed that older surgeons tend to have lower complication rates. Additionally, factors like smoking, obesity, and gender were identified as influential in postoperative complications. Conclusions: Advancing age is independently associated with an increased risk of postoperative complications in plastic surgery. The study highlights the need for a comprehensive approach to evaluate postoperative outcomes, considering various patient and surgeon factors.

Novel Noninvasive Hybrid Flap Preconditioning (HFP) Surpasses Surgical Delay in the Murine Model.

Ischemic necrosis in the distal portion of the flap is a challenging complication in plastic surgery. We hypothesize a novel hybrid flap preconditioning (HFP) device combining foam-mediated external suction and non-surgical delay can promote skin flap survival better than surgical delay. Twenty-eight mouse were divided into four groups. Control group: a 4*1.5 dorsal flap was made with no preconditioning. Surgical delay (SD) group: surgical delay was made 7 days before flap elevation. Foam-mediated external suction (FMES) group: foam-mediated external suction at -100mmHg was employed 5 hours per day for 6 days, and the flap was elevated on the seventh day. Hybrid Flap Preconditioning (HFP) group: silicone strips was applied along the contour of the foam interface. Same negative pressure protocol was used as the FMES group. Seven days after flap elevation, macroscopic, histologic, and Western blot analyses were performed. The flap survival rate was 46.25% (8.12%) in the control group, 68.72% (7.00%) in the SD group, 57.03% (8.17%) in the FMES group and 80.66% (3.27%) in the HFP group. Immunohistologic analysis of CD 31+ cell in distal end of viable tissue procured seven days after flap elevation showed a significantly higher angiogenesis in SD group and HFP group. Western Blot results showed an increased expression of VEGF in SD group and HFP group. We have developed and fabricated a novel hybrid flap precondition (HFP) device combining foam-mediated external suction and non-surgical delay. The concept of HFP is proved to promote flap survival better than surgical delay.

Preoperative hypovitaminosis D and complications in plastic surgery: a pilot study.

Vitamin D plays a crucial role in various biological processes, including the well-known regulation of the immune system and calcium metabolism. While its involvement in the surgical outcomes of various medical specialties is recognized, there is a lack of consistent data regarding plastic surgery. This study aimed to assess preoperative serum levels of 25-hydroxyvitamin D and its relationship with complications in patients undergoing reconstructive and aesthetic plastic surgeries. prospective and observational cohort study, conducted from October 2021 to August 2023 at the Hospital das Clínicas, Universidade Federal de Pernambuco, involving 83 patients. vitamin D levels were deemed deficient in 7 (8,4%) patients, insufficient in 36 (43,4%), and sufficient in 40 (48,2%). No direct association was demonstrated between deficient or insufficient serum levels of 25-hydroxyvitamin D and the incidence of complications in plastic surgery, even when considering comorbidities. preoperative hypovitaminosis D was not associated with complications in plastic surgery.

Complications of Reconstructive Surgery in Head and Neck Region: A Cross-Sectional Study from Bangladesh

Background Microvascular free flaps are ideal for reconstructing post-oncological surgery defects in the head and neck region. Free flaps provide ample tissue for reconstructing even large, complex defects, which gives oncosurgeons flexibility during tumor resections. Methods We performed 50 free flap head and neck reconstructions in 978 patients from June 2015 to September 2018. For reconstructing bone defects, our flap of choice was the free fibula. The surgical outcomes and complications according to flap were retrospectively reviewed and analyzed. Results The overall flap success rate was 98.1%. A total of 45 cases required emergency surgical re-exploration for compromised flaps and 19 of these flaps could not be salvaged. Venous insufficiency was the most common cause of surgical re-exploration. Flaps with delayed arterial thrombosis and vascular compression could not be salvaged. Other complications were partial flap necrosis, oro-cutaneous fistula, and donor site complications. No statistically significant differences were noted for complications in elderly and post-radiotherapy patients. Conclusions Free flap reconstruction is a robust and highly reliable option for head and neck defects and free flaps are a safe option for treating large defects. A second free flap should be the first choice in failed cases after the medical optimization of the patient. Free flap reconstruction is safe in elderly and post-radiotherapy patients.

Occurrence and treatment of peripheral nerve injuries after cosmetic surgeries.

Although non-invasive and minimally invasive aesthetic procedures increasingly dominate the cosmetic market, traditional plastic surgery remains the most effective improvement method. One of the most common complications in plastic surgery, peripheral nerve injuries, though has a low incidence but intrigued plastic surgeons globally. In this article, a narrative review was conducted using several databases (PubMed, EMBASE, Scopus, and Web of Science) to identify peripheral nerve injuries following cosmetic surgeries such as blepharoplasty, rhinoplasty, rhytidectomy, breast surgeries, and abdominoplasty. Surgery-related nerve injuries were discussed, respectively. Despite the low incidence, cosmetic plastic surgeries can cause iatrogenic peripheral nerve injuries that require special attention. The postoperative algorithm approaches can be effective, but the waiting and treatment processes can be long and painful. Preventive measures are undoubtedly more effective than postoperative remedies. The best means of preventing disease is having a good understanding of anatomy and conducting a careful dissection.

Treatment of Soft Tissue Defects after Minimally Invasive Plate Osteosynthesis in Fractures of the Distal Tibia: Clinical Results after Reverse Sural Artery Flap.

Introduction: Distal tibial fractures make up approximately 3% to 10% of all tibial fractures or about 1% of lower extremity fractures. MIPO is an appropriate procedure and method to achieve stable metal plate fixation and osseointegration by minimizing soft tissue damage and vascular integrity at the fracture site. MIPO to the medial tibia during distal tibial fractures induces skin irritation due to the thickness of the metal plate, which causes discomfort and pain on the medial side of the distal leg, and if severe, complications such as infection and skin defect may occur. The reverse sural flap is a well-researched approach for covering defects in the lower third of the leg, ankle, and foot. Materials and Methods: Among 151 patients with distal tibia fractures who underwent minimally invasive metal plate fixation, soft tissue was injured due to postoperative complications. We treated 13 cases with necrosis and exposed metal plates by retrograde nasogastric artery flap surgery. For these patients, we collected obligatory patient records, radiological data, and wound photographs of the treatment results and complications of reconstructive surgery. Results: In all the cases, flap survival was confirmed at the final outpatient follow-up. The exposed area of the metal plate was well coated, and there was no plate failure due to complete necrosis. Three out of four women complained of aesthetic dissatisfaction because the volume of the tunnel through which the skin mirror passed and the skin plate itself were thick. In two cases, defatting was performed to reduce the thickness of the plate while removing the metal plate. Conclusions: Metal plate exposure after distal tibial fractures have been treated with minimally invasive metal plate fusion and can be successfully treated with retrograde nasogastric artery flaps, and several surgical techniques are used during flap surgery.

The Controlling Nutritional Status (CONUT) Score for Prediction of Microvascular Flap Complications in Reconstructive Surgery.

Microvascular flap surgery is a widely acknowledged procedure for significant defect reconstruction. Multiple flap complication risk factors have been identified, yet there are limited data on laboratory biomarkers for the prediction of flap loss. The controlling nutritional status (CONUT) score has demonstrated good postoperative outcome assessment ability in diverse surgical populations. We aim to assess the predictive value of the CONUT score for complications in microvascular flap surgery. This prospective cohort study includes 72 adult patients undergoing elective microvascular flap surgery. Preoperative blood draws for analysis of full blood count, total plasma cholesterol, and albumin concentrations were collected on the day of surgery before crystalloid infusion. Postoperative data on flap complications and duration of hospitalization were obtained. The overall complication rate was 15.2%. True flap loss with vascular compromise occurred in 5.6%. No differences in flap complications were found between different areas of reconstruction, anatomical flap types, or indications for surgery. Obesity was more common in patients with flap complications (p = 0.01). The CONUT score had an AUC of 0.813 (0.659-0.967, p = 0.012) for predicting complications other than true flap loss due to vascular compromise. A CONUT score > 2 was indicated as optimal during cut-off analysis (p = 0.022). Patients with flap complications had a longer duration of hospitalization (13.55, 10.99-16.11 vs. 25.38, 14.82-35.93; p = 0.004). Our findings indicate that the CONUT score has considerable predictive value in microvascular flap surgery.

Place and objectives of ultrasound examination of the mammary glands after augmentation mammoplasty with silicone endoprostheses in the instrumental algorithm of patients with suspected BIA-ALCL (literature review)

In the 90s of the last century, the first isolated cases of the occurrence of T-cell non-Hodgkin's lymphoma of the breast after augmentation mammoplasty with silicone endoprostheses were identified. For many years, this disease was considered very rare and was not associated with the presence of implants. In the future, the number of patients with this pathology began to increase. In 2012, the FDA identified an association between anaplastic large cell T lymphoma and breast implants and introduced the term Breast Implant-Associatad Anaplastic Large Cell Lymphoma (BIA-ALCL), which is now recognized as a new disease by the WHO. Active study of BIA-ALCL continues today. An increase in the estimated risk of developing this severe complication of plastic surgery was noted.Purpose: to present a literature review of materials covering the problems associated with the most severe complication of augmentation mammoplasty – BIA-ALCL; to determine the place and tasks of ultrasound in the proposed diagnostic instrumental algorithm for patients with suspected BIA-ALCL based on a set of ultrasound criteria.Materials and methods. The analysis of literary sources on the topic "BIA-ALCL" was carried out. With the accumulation of experience in the diagnosis and treatment of patients with BIA-ALCL, the number of papers presenting clinical observations on this topic has increased in the available literature. From 2013 to December 2022, PUBmed found 324 search results in the BIA-ALCL section. The vast majority of English-language papers – about 200 – were published in 2020 and 2021. Single publications are presented in Russian.Based on world experience in 2016, recommendations for the diagnosis and treatment of patients with BIAALCL were developed and updated in 2019. According to the literature, three criteria have been formulated that should be paid special attention in order not to miss this disease: the accumulation of a significant amount of fluid in the periprosthetic space (occurs in 60% of cases), the presence of additional masses in this fluid (8–24%), and axillary pathological lymphadenopathy (4–12%). Instrumental examination of patients with suspected BIA-ALCL is recommended to begin with ultrasound or MRI. The prevalence of the process is assessed by PET/CT.It is necessary to raise the awareness of doctors and patients about the possibility of developing this complication of plastic surgery, to actively continue the study and search for diagnostic criteria for BIA-ALCL to identify the process in the early stages of the disease.

From Risk Assessment to Intervention: A Systematic Review of Thrombosis in Plastic Surgery.

Thromboembolismis a feared complication in plastic surgery and is linked to higher rates of morbidity and mortality. Despite extensive research, there is a lack of consistency between recommendations and clinical protocols to be implemented pre and post-surgery to reduce the incidence of thromboembolism.A systematic literature review was conducted using Pubmed and Scopus databases to determine the risk factors, screening methods, and existing treatment models for thromboembolism prevention. Articles in non-English languages were excluded.Analysis indicated that predominant risk factors include age (>35), elevated body mass index, coagulation disorders, smoking, estrogen therapies, genetic predisposition, vascular endothelium damage, stasis, and use of general anesthesia in patients with a history of cancer. Implementation of a proper prophylactic protocol is dependent on understanding the interplay between the aforementioned risk factors and the utilization of well-defined, evidence-based guidelines, such as the 2005 Caprini Risk Assessment Modeland ultrasound surveillance. The literature review revealed that mechanical prophylaxis is the primary prevention method, followed by thromboprophylaxis for patients with higher Caprini scores. Plastic surgeons often underestimate the present risk stratification tools available for the prophylactic intervention of thromboembolism due to the fear of bleeding or hematoma complications postoperatively. In summary, this literature review emphasizes the importance of plastic surgeons selecting protocols that is inclusive of the patient's risk profile to yield a reduced risk of thromboembolism.

The safety of breast reconstruction: The impact of breast reconstruction surgery on postoperative adjuvant therapy for breast cancer.

Results: Of the 1044 patients who received adjuvant chemotherapy, the median time from the date of surgery to the start of chemotherapy was 51.0 days, with 65 patients (6.2%) starting more than 90 days after surgery. 66 IBR complications required surgery, including infections and tissue expander (TE) removal. Of the 65 patients for whom chemotherapy was initiated 90 days or more after surgery, 9 patients (13.8%) had complications requiring surgery, significantly more than the 57 patients (5.8%) in the < 90 days group (P = 0.010). Post-mastectomy radiation therapy (PMRT) was performed after breast cancer surgery in 359 cases: 69 cases received autologous tissue irradiation, 46 TE irradiation, 241 silicone breast implant (SBI) irradiation, and 3 removal before irradiation. 5 cases given autologous tissue irradiation and 30 receiving artificial material irradiation required surgery within 1 year after the cancer surgery due to complications of IBR. There was no significant difference in the frequency of complications requiring surgery between autologous tissue irradiation and artificial material irradiation (P = 0.422). There were 35 complications (9.7%) requiring surgery in the irradiated group, significantly more than the 118 cases (2.7%) in the non-irradiated group (P < 0.001). Conclusions: Adjuvant chemotherapy was generally not delayed, but complications requiring surgery related to IBR were more frequent in those with delay beyond 90 days, suggesting that postoperative complications from breast reconstruction may have influenced the delay in initiating chemotherapy. Therefore, in cases for whom postoperative chemotherapy is anticipated, complications from breast reconstruction may have impacted outcomes, making preoperative risk assessment even more important. There was no difference in the frequency of reconstructive complication surgery according to whether autologous tissue irradiation or artificial material irradiation had been used, but further investigation is needed.

Common Complications in Reconstructive Surgery

Reconstructive surgery is a surgical technique used to restore the function and appearance of tissues that have been damaged or removed due to previous illnesses, injuries, or surgeries. Complications of reconstructive surgery are a major concern for patients and surgeons. Complications can affect patients quality of life, increase healthcare costs, and prolong recovery time. It is important that patients are fully informed about the risks and benefits of reconstructive surgery, and that surgeons take steps to minimize the risk of complications.

Evaluation of facial artery course variations, diameters, and depth by Doppler ultrasonography

The facial artery (FA) is the main blood vessel supplying blood to the face. It is essential to understand the anatomy of FA around the nasolabial fold (NLF). This study aimed to provide the detailed anatomy and relative positioning of FA to help avoid unexpected complications in plastic surgery. FA was observed from the inferior border of the mandible to the end of its terminal branch in 66 hemifaces of 33 patients with Doppler ultrasonography. The evaluation parameters were: (1) location, (2) diameter, (3) FA-skin depth, (4) relationship between the NLF and FA, (5) distance between the FA and significant surgical landmarks, and (6) the running layer. The FA course is classified based on the terminal branch. The most common FA course was Type 1, which had an angular branch as the final branch (59.1%). The most common FA-NLF relationship was that the FA was situated inferior to the NLF (50.0%). The mean FA diameter was 1.56±0.36mm at the mandibular origin, 1.40±0.37mm at the cheilion, and 1.32±0.34mm at the nasal ala. The FA diameter on the right hemiface was thicker than that on the left hemiface (p<0.05). The FA mainly terminates in the angular branch, running in the medial NLF and in dermis and subcutaneous tissue, with a blood supply advantage in the right hemisphere. We suppose that a deep injection into periosteum around the NLF may be safer than an injection into the superficial musculoaponeurotic system (SMAS) layer.

Frailty Indices Outperform Historic Risk Proxies as Predictors of Postabdominoplasty Complications: An Analysis of a National Database.

Although age, body mass index (BMI), and major comorbidities were historically used as predictors of surgical risk, recent literature supports patient frailty as a more accurate predictor. Database studies and chart reviews support the modified Charlson Comorbidity Index (mCCI) and the Modified Five-Item Frailty Index (mFI-5) as predictors of postsurgical complications in plastic surgery. The authors hypothesized that the mFI-5 and mCCI are more predictive of abdominoplasty complications than historic risk proxies. A retrospective review of the American College of Surgeons National Surgical Quality Improvement Program database was performed for abdominoplasty patients from 2013 to 2019. Demographics, comorbidities, and complications were gathered. The mFI-5 and mCCI scores were calculated per patient. Age, BMI, major comorbidities, American Society of Anesthesiologists class, mFI-5 score, and mCCI score were compared as predictors of all-cause 30-day complications, 30-day surgical-site complications, length of stay, and aggregate Clavien-Dindo complication severity score. Of 421 patients, the strongest predictors for all-cause complications and complication severity were mCCI score greater than or equal to 3 and mFI-5 score greater than or equal to 2. The mFI-5 score was the strongest predictor of unplanned reoperation. Length of stay was best predicted by age greater than or equal to 65. The only predictor of surgical-site complications was BMI greater than or equal to 30.0 kg/m 2 . Smoking was predictive of complication severity, but not any other outcome. The mFI-5 and mCCI are stronger outcome predictors than historically used factors, which showed little predictive value in this cohort. Although the mCCI is a stronger predictor than the mFI-5, the mFI-5 is easily calculated during an initial consultation. Surgeons can apply these tools to aid in risk stratification for abdominoplasty. Risk, III.

Siliconose avec polyarthrite rhumatoïde dans les suites d’une rupture d’implant mammaire : cas clinique et revue de la littérature

Breast implant rupture is a common complication in plastic surgery, with various clinical presentations, due to silicone migration. In this article, we present the case of a patient with ruptured silicone implants, who developed siliconosis with rheumatoid polyarthritis, and evolved favourably after explantation surgery. The physiopathology of this disease, and the implication of silicone migration are still controversial, and yet to be confirmed.

Continuous intraoperative perfusion monitoring of free microvascular anastomosed fasciocutaneous flaps using remote photoplethysmography

Flap loss through limited perfusion remains a major complication in reconstructive surgery. Continuous monitoring of perfusion will facilitate early detection of insufficient perfusion. Remote or imaging photoplethysmography (rPPG/iPPG) as a non-contact, non-ionizing, and non-invasive monitoring technique provides objective and reproducible information on physiological parameters. The aim of this study is to establish rPPG for intra- and postoperative monitoring of flap perfusion in patients undergoing reconstruction with free fasciocutaneous flaps (FFCF). We developed a monitoring algorithm for flap perfusion, which was evaluated in 15 patients. For 14 patients, ischemia of the FFCF in the forearm and successful reperfusion of the implanted FFCF was quantified based on the local signal. One FFCF showed no perfusion after reperfusion and devitalized in the course. Intraoperative monitoring of perfusion with rPPG provides objective and reproducible results. Therefore, rPPG is a promising technology for standard flap perfusion monitoring on low costs without the need for additional monitoring devices.
