[PMID: 38775663 PMCID: PMC11358639 DOI: 10.1093/dmfr/twae020] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2023] [Revised: 04/07/2024] [Accepted: 05/07/2024] [Indexed: 08/30/2024] Open
Abstract
OBJECTIVE This study aims to develop a facial vascular enhancement imaging system and analyze vascular distribution in the facial region to assess its potential in preventing unintended intravascular injections during cosmetic facial filling procedures. METHODS A facial vascular enhancement imaging system based on optical detection technology was designed, and volunteers were recruited. The system was utilized to detect and analyze vascular distribution in various anatomical regions of the faces. The vascular visualization-enhanced (VVE) images generated by the system were compared with visible light images to validate the vascular visualization capability of the system. Additionally, the reliability of vascular visualization was assessed by comparing the observed vascular patterns in the VVE images with those in near-infrared light images. RESULTS Thirty volunteers were recruited. The VVE images produced by the system demonstrated a significant capacity to identify vascular morphology and yielded a higher vessel count compared to visible light images, particularly in the frontal, orbital, perioral, mental, temporal, cheek, and parotid masseter regions (P < .05). The temporal region exhibited the highest vascular density, followed by the cheek region and then the frontal region. Reliability analysis of vascular visualization enhancement indicated that the system's imaging of facial vasculature not only demonstrated reliability but also enhanced physicians' visual perception. CONCLUSION Blood vessel distribution varies across facial regions. The facial vascular enhancement imaging system facilitates real-time and clear visualization of facial vasculature, offering immediate visual feedback to surgeons. This innovation holds promise for enhancing the safety and effectiveness of facial filling procedures.

Han Y, Liu C, Wu G. Cerebral Complications Following Facial Autologous Fat Graft Injection: A Systematic Review and Meta-analysis. Aesthetic Plast Surg 2024:10.1007/s00266-024-04268-8. [PMID: 39093359 DOI: 10.1007/s00266-024-04268-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2024] [Accepted: 07/15/2024] [Indexed: 08/04/2024]
Abstract
BACKGROUND With the increasing use of autologous fat (AF) grafting in plastic surgery, the occurrence of complications has garnered the attention from plastic surgeons. This study aims to estimate the cerebral complications following facial AF graft injection objectively and systematically with newly published literature. METHODS A comprehensive literature search was conducted systematically on PubMed, Embase, Web of Science, Cochrane, and ClinicalTrials.gov for articles published between 2000 and 2023. A systematic review and meta-analysis were performed in accordance with PRISMA guidelines. RESULTS A total of 11 articles comprising of 37 participants were included, all of which are case reports. For AF facial filling, the incidence rate of cerebral embolism among cases of cerebral and ocular embolism was found to be 60% (95% CI 0.41-0.79). The incidence of cerebral embolism presenting with initial symptoms of unconsciousness was 69% (95% CI 0.48-0.9), with limb movement disorders was 55% (95% CI 0.26-0.84), and with vision loss was 30% (95% CI 0.12-0.49). The incidence of cerebral embolism with ophthalmic artery occlusion was 36% (95% CI 0.20-0.53), compared to was 71% (95% CI 0.48-0.95) without ophthalmic artery occlusion. CONCLUSIONS AF grafting is generally safe and minimally invasive. However, with its widespread use as facial injection filling for cosmetic enhancement, the incidence of cerebral complications, such as cerebral infarction, has also increased. It is imperative to properly manage high-risk factors for cerebral embolism during the perioperative period to prevent its occurrence.

Abstract
INTRODUCTION The rising use of soft tissue fillers for aesthetic procedures has seen an increase in complications, including vascular occlusions and neurological symptoms that resemble stroke. This study synthesizes information on central nervous system (CNS) complications post-filler injections and evaluates the effectiveness of hyaluronidase (HYAL) treatment. METHODS A thorough search of multiple databases, including PubMed, EMBASE, Scopus, Web of Science, Google Scholar, and Cochrane, focused on publications from January 2014 to January 2024. Criteria for inclusion covered reviews and case reports that documented CNS complications related to soft tissue fillers. Advanced statistical and computational techniques, including logistic regression, machine learning, and Bayesian analysis, were utilized to dissect the factors influencing therapeutic outcomes. RESULTS The analysis integrated findings from 20 reviews and systematic analyses, with 379 cases reported since 2018. Hyaluronic acid (HA) was the most commonly used filler, particularly in nasal region injections. The average age of patients was 38, with a notable increase in case reports in 2020. Initial presentation data revealed that 60.9% of patients experienced no light perception, while ptosis and ophthalmoplegia were present in 54.3 and 42.7% of cases, respectively. The statistical and machine learning analyses did not establish a significant linkage between the HYAL dosage and patient recovery; however, the injection site emerged as a critical determinant. CONCLUSION The study concludes that HYAL treatment, while vital for managing complications, varies in effectiveness based on the injection site and the timing of administration. The non-Newtonian characteristics of HA fillers may also affect the incidence of complications. The findings advocate for tailored treatment strategies incorporating individual patient variables, emphasizing prompt and precise intervention to mitigate the adverse effects of soft tissue fillers.

Abstract
BACKGROUND Intravascular injection represents the most severe complication in fat transplantation procedures. Currently, the prognosis for patients who suffer from blindness due to fat transplantation-induced ocular vascular occlusion is far from optimistic. OBJECTIVES The aim of this study was to explore and evaluate the efficacy and safety of arterial thrombolysis in the treatment of ocular vascular occlusion caused by fat transplantation. METHODS We analyzed the data of 12 patients who underwent intraarterial thrombolysis and conservative treatments for facial autologous fat grafting-associated ocular vascular occlusion. Among the cases, there were 6 instances of ophthalmic artery embolism and 6 cases of central retinal artery occlusion. All patients suffered with sudden blindness, sometimes accompanied by eye pain, ptosis, strabismus, skin necrosis at the injection site, or cerebral microinfarction. They received symptomatic conservative treatments and intraarterial thrombolysis, encompassing mechanical vessel recanalization, vessel dilation, and dissolution of thrombus constituents. RESULTS Following intraarterial thrombolysis, a noteworthy improvement in the blood flow of both the main trunk and peripheral branches of the ophthalmic artery was observed in the majority of patients when contrasted with their pretreatment status. One patient experienced a headache intraoperatively, while no significant discomfort was reported by the remaining patients. After conservative treatments and intraarterial thrombolysis, all patients experienced improvement in ocular symptoms, skin necrosis, and cerebral infarction. Three patients demonstrated improvement in visual acuity. These patients had surpassed the recommended time window for treatment, yet the occlusion of the ophthalmic artery was not complete. CONCLUSIONS Intraarterial thrombolysis combined with conservative treatments achieves early perfusion and is expected to promote visual recovery. Hospitals that possess the necessary treatment capabilities are encouraged to establish this therapeutic pathway.

Abstract
BACKGROUND While autologous fat grafting of the face is considered a generally safe procedure, severe complications such as arterial embolism (AE) have been reported. OBJECTIVE To summarize data on injection-related visual compromise, stroke, and death caused by arterial embolism after facial fat transplantation. MATERIALS AND METHODS Plastic surgery societies were contacted for reports on AE after autologous facial fat injection. In addition, a systematic literature review was performed. Data extracted included study design, injection site/technique, symptoms, management, outcome, and etiology. RESULTS 61 patients with a mean age of 33.56 ± 11.45 years were reported. Injections targeted the glabella or multiple facial regions (both n = 16/61, 26.2%) most commonly, followed by injections in the temples (n = 10/61, 16.4%) and the forehead (n = 9/61, 14.8%). The mean volume injected was 21.5 ± 21.5 ml. Visual symptoms were described most frequently (n = 24/58, 41.4%) followed by neurological symptoms (n = 20/58, 34.5%), or both (n = 13/58, 22.4%). Ophthalmic artery (OA, n = 26/60, 43.3%), anterior or middle cerebral artery (CA, n = 11/60, 18.3%) or both (n = 14/60, 23.3%) were most frequently occluded. Outcome analysis revealed permanent vision loss in all patients with OA occlusion (n = 26/26, 100%), neurological impairment in most patients with CA occlusion (n = 8/10, 80%), and vision loss in most patients suffering from both OA and CA occlusion (n = 7/11, 63.6%). Six patients died following embolisms. CONCLUSIONS AE causes severe complications such as blindness, stroke, and death. Due to a lack of high-quality data, no evidence-based treatment algorithms exist. To increase patient safety, a database collecting cases and complications should be established.

Abstract
Background Severe cerebral artery embolism is a rare complication of facial autologous fat injection. However, its incidence has markedly increased with the recent rise in facial cosmetic procedures. Case presentation We report a 31-year-old Chinese woman who presented with unconsciousness 6 h after having undergone a facial autologous fat injection. A neurological examination revealed stupor, bilaterally diminished pupillary light reflexes, right-sided central facial palsy, and no reaction to pain stimulation of right limbs. Diffusion-weighted imaging displayed patchy hyperintense lesions in the left frontal, parietal, and temporal lobes. Magnetic resonance angiography demonstrated fat embolism in the left internal carotid artery, anterior cerebral artery, and middle cerebral artery. We immediately performed mechanical thrombectomy under sufficient preoperative preparations but failed to achieve complete recanalization. Pathological examination of the embolus confirmed the presence of adipocytes. Although we actively administered symptomatic and supportive treatments, the patient eventually died due to the progression of cerebral herniation and systemic infection. Conclusion Due to the ineffectiveness of current treatment and the inferior prognosis, fat embolism, a severe complication of autologous fat graft, should draw the attention of both plastic surgeons and neurologists so that actions may be taken for both its prevention and treatment.

J Clin Med 2022; 11:jcm11164708. [PMID: 36012947 PMCID: PMC9410081 DOI: 10.3390/jcm11164708] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/22/2022] [Revised: 07/25/2022] [Accepted: 07/25/2022] [Indexed: 11/30/2022] Open
Abstract
Introduction: Autologous fat is ideal soft tissue filler. It is easily accessible, biocompatible, cheap, and it provides both volume augmentation and skin quality improvement. Fat grafting has been used since 1893, but it has only gained widespread popularity since the development of modern liposuction by Colemann and Illouz in the 1980s. Every year more than half a million facial fat grafting procedures are carried out worldwide and the trend is rapidly increasing. Overall, general complications associated with facial fat grafting are assumed to be around 2%. Is that true? Material and Methods: Until July 2021, a systematic search of the literature was performed interrogating PubMed search engines. The following algorithm was used for the research: (fat graft OR lipofilling) AND face AND complications. Exclusion criteria applied hierarchically were review articles, not reporting recipient site complications; not in English and paediatric population. Abstracts were manually screened by LS, GS, JM and PDS separately and subsequently matched for accuracy. Pertinent full-text articles were retrieved and analysed and data were extracted from the database. The flow chart of article selection is described following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Results: In total, 462 papers were identified by PubMed search. A total of 359 were excluded: 38 papers were not in English, 41 were review articles, 279 articles did not report recipient site complications and 1 was not on human subjects. Average complication rate ranged from 1.5% to 81.4%. A total of 298 adverse events were identified: 40 (13.4%) intravascular injections, 13 (4.3%) asymmetry, 57 (19.1%) irregularities, 22 (7.4%) graft hypertrophy, 21 (7%) fat necrosis, 73 (24.5%) prolonged oedema, 1 (0.3%) infection, 6 (2%) prolonged erythema, 15 (5%) telangiectasia and 50 (16.8%) cases of acne activation. Conclusions: FFG related side effects could be resumed in three categories: severe, moderate, and minor. Severe (13.4%) side effects such as intravascular injection or migration require neurological or neurosurgical management and often lead to permanent disability or death. Moderate (38.3%) side effects such as fat hypertrophy, necrosis, cyst formation, irregularities and asymmetries require a retouch operation. Minor (48.3%) side effects such as prolonged oedema or erythema require no surgical management. Despite the fact that the overall general complication rate of facial fat grafting is assumed to be around 2%, the real complication rate of facial fat grafting is unknown due to a lack of reporting and the absence of consensus on side effect definition and identification. More RCTs are necessary to further determine the real complication rate of this procedure.

Abstract
BACKGROUND Autologous facial fat grafting has gained popularity in recent years and is considered to be safe. This paper presents the case of a patient who died due to massive cerebral microfat embolism after facial fat grafting. OBJECTIVES The aim of this study was to raise awareness and provide more evidence on the prevention and treatment of this potentially lethal complication of facial fat grafting. METHODS A detailed report was made of the case. Two online databases were searched for similar cases of facial fat embolism resulting in neurologic and/or visual symptoms. Thereafter a literature search was conducted to verify the etiology, current treatment options, and preventive measures. RESULTS Forty-nine cases with similar events were found in the literature. The most common injected area was the glabella (36.1%), and an average of 16.7 mL fat was injected. The main complications were visual impairment, with 88.5% of cases resulting in permanent monocular blindness, and neurologic symptoms, some of which never fully recovered. Including the present patient, 7 cases were fatal. Fat embolism can occur in the veins and arteries of the face. Two possible pathways for fat embolism exist: the macroscopic, mechanical pathway with immediate signs, and the microscopic, biochemical pathway with delayed symptoms. Mechanical embolectomy and corticosteroids are suggested treatment options but evidence for their efficacy is lacking. Several different preventive measures are described. CONCLUSIONS Although facial fat grafting is considered a safe procedure, one should be aware of the risk of fat embolism. Underreporting of this adverse event is likely. With no effective treatment and often detrimental outcomes, preventive measures are of utmost importance to improve patient safety. LEVEL OF EVIDENCE: 4

Abstract
Background With the growth in the popularity of facial filler injections, increased numbers of severe adverse events, such as cerebral embolism, have been reported. Objectives The aim of this article was to summarize the clinical manifestations and proposed mechanisms of filler-induced cerebral embolism (FICE). Methods A literature review was performed with the search keywords “filler injection,” “hyaluronic acid,” “fat graft,” “cerebral infarction,” “cerebral embolism,” “stroke,” “cerebrovascular infarction,” “disorders of consciousness,” and “hemiplegia.” Results Among the 43 cases of FICE enrolled from 35 articles, 37 patients were female, and 6 were male. Twenty-nine of these patients had received fat grafting, and 12 hyaluronic acid injection. Most FICE patients had been injected in the glabella, followed by the temporal, forehead, and nasal areas. Among 30 patients injected under local anesthesia, 43.33% presented with neurologic symptoms during the procedure. The main symptoms were consciousness disorders and hemiplegia. Most of the embolization sites were in the middle cerebral artery, followed by frontal lobe infarction and anterior cerebral artery infarction. Three patients developed cerebral hemorrhage after embolism. Twenty-six patients presented with newly acquired vision loss. The management for FICE cases included embolectomy, thrombolysis, decompressive craniectomy, antiplatelet/anticoagulant therapy, and symptomatic and nutritional treatment. Nearly half of the patients recovered or exhibited improved neurologic manifestations but not visual loss. Five patients died. Conclusions FICE is a severe complication following facial filler injection. Careful prevention, timely identification, and treatment are crucial to decreasing the morbidity and mortality of FICE.

[PMID: 34702212 PMCID: PMC8549338 DOI: 10.1186/s12883-021-02419-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/09/2021] [Accepted: 09/29/2021] [Indexed: 02/08/2023] Open
Abstract
Background Cerebral fat embolism (CFE) is a subtype of fat embolism syndrome which tends to cause ischemic cerebral infarction. Fat embolism in the cerebral venous system have not been reported. We hereby present a rare case of fat embolus formed in the cerebral venous system 10 days after cosmetic surgery, and describe our management of this patient. Case presentation A 26-year-old woman with the disturbance of consciousness and recurrent convulsions of the right upper extremity over a 21-h period was admitted to our hospital. The patient was initially diagnosed with haemorrhagic infarction, and cerebral venous thrombosis (CVT) was suspected based on computed tomography (CT). A diagnosis of CFE was confirmed based on surgical findings. Breast and hip augmentation performed 10 days ago was considered the underlying cause. Drug-induced hypothermia, low molecular weight heparin, atorvastatin, dexamethasone, piperacillin/tazobactam, valproic acid, and mannitol were applied. On hospital day 30, she was discharged with a Montreal Cognitive Assessment score of 25. Conclusions Fat embolism can occur in the cerebral venous system, and may mimic CVT symptoms rather than CFE symptoms. Early identification of the nature of the embolus is essential. The use of heparin may prevent secondary thrombus formation, and accelerate fat embolus decomposition.

Abstract
BACKGROUND Vascular embolism is the most severe complication after autologous fat grafting. With a worldwide increase in fat grafting, there has been a rise in severe vascular complications, such as ophthalmic artery embolism, cerebral artery embolism, and even death. This article aims to review the role of fat in causing severe vascular complications and the association between fat grafting and severe vascular complications. METHODS A critical review was conducted by appraising the cases of severe vascular complications associated with facial fat grafting reported globally. Repeated cases that were reported in multiple publications were further screened. RESULTS The final search yielded 50 publications in English that met the inclusion criteria for review. A total of 113 cases of fat-induced severe vascular complications in the literature were identified. The number of cases reported yearly has increased over time, with even more significant increases since 2010. The glabella and temple are the most common sites of severe vascular complications described in the literature. In addition, only one case of ophthalmic artery embolism and one case of cerebral artery embolism have been treated successfully. CONCLUSIONS Given the increase in reported cases of severe vascular complications, both doctors and patients should pay careful attention to the risks of facial fat grafting. Because of the unclear mechanism of vascular embolism and the lack of guidelines for prevention and treatment, the effective cure rate is unsatisfactory. We propose that preventing vascular embolism is a priority in fat grafting and that timely, multidisciplinary treatment should be performed when severe vascular complications occur. It is necessary in future studies to explore the mechanisms of vascular embolism and effective treatment strategies to promote the development of fat grafting.

Abstract
Facial fat grafting techniques often offer impressive surgical results. However, fatal complications, such as irreversible cerebral ischemia, blindness, and hemiplegia are associated with them. We have presented a case report of a patient who presented with a massive cerebral infarction, a serious complication of facial autologous fat injection. The patient was a 28-year-old female who experienced motor dysfunction of the left extremities, which was accompanied with loss of consciousness immediately following fat grafting for facial augmentation. Imaging studies suggested that the patient had a large cerebral infarction on the right frontal, temporal, and parietal lobes due to complete occlusion of her right external carotid artery. Emergency decompressive craniectomy was completed in addition to multiple follow-up medical treatments. The patient recovered after 4 months with reduced motor function in her left upper extremity. This report further summarizes published cases of massive cerebral ischemia after facial injection of autologous fat, as well as lists high-risk facial areas and critical warnings.

Abstract
RATIONALE Fat embolism syndrome with cerebral fat embolism, rarely observed at our neurology department, is often associated with long bone fractures. Its diagnosis is based on medical history and supportive imaging data and is usually not difficult. However, its pathogenesis remains poorly understood. PATIENT CONCERNS A 46-year-old woman was urgently presented to a nearby hospital because of a femur fracture caused by an accident. She rapidly developed somnolence and was suspected to have fat embolism syndrome. DIAGNOSES Due to patients history of trauma and supportive imaging data, she was diagnosed with fat embolism syndrome obviously. However, severe brain damage confused our understanding of the pathogenesis. The subsequent diagnosis of fat embolism syndrome with patent foramen ovale provided a reasonable explanation. INTERVENTIONS Initially, we did not consider the fact that the patient had developed fat embolism syndrome and thus designed a comprehensive treatment program for fat embolism syndrome. Then the routine cardiac and vascular ultrasound screening were followed up, but patent foramen ovale was diagnosed unexpectedly, which led to a more aggressive treatment of brain injury. OUTCOMES After relevant symptomatic treatment continued for nearly 3 months, an overall improvement was observed. Patients consciousness was restored but language disorders were left. LESSONS Clinicians should consider patent foramen ovale as the embolization pathway, particularly in young and middle-aged patients with cerebral embolism because it is often mistaken for a rare situation.

Abstract
RATIONALE Fat embolism syndrome (FES) is characterized by the classical triad of cerebral, respiratory, and cutaneous manifestations. In contrast, cerebral fat embolism (CFE), corresponding to incomplete pure type FES, is much rarer and usually follows trauma. CFE typically shows a "starfield" pattern on diffusion-weighted magnetic resonance imaging due to the involvement of multiple small arteries. We report 2 unusual cases of CFE that showed a nontraumatic etiology and the involvement of a single dominant cerebral artery. PATIENT CONCERNS Case 1 was a 33-year-old woman without a history of trauma who visited the emergency room due to hemiparesis and hemisensory deficits. She was a heavy smoker and had used oral contraceptives for several years. Most importantly, she had 2 experiences of autologous fat grafting 2 months previously. Magnetic resonance angiography (MRA) revealed acute occlusion of the right middle cerebral artery. Case 2 was an 80-year-old man suddenly presented with dizziness, ataxia, and left-sided sensorimotor dysfunction. He had a history of hypertension, untreated atrial fibrillation, and chronic alcoholism. MRA demonstrated the occlusion of the distal basilar artery. DIAGNOSIS Case 1: Microscopic findings demonstrated variable sized fat vacuoles intermixed with moderate amounts of thrombi. Case 2: Histologically, mature adipocytes were intermingled with fibrin, blood cells, and a fragment of entrapped soft tissue resembling the vessel wall. INTERVENTION Case 1 and 2 underwent aspirational thrombectomy guided by transfemoral cerebral angiography. OUTCOME Case 1 recovered well but Case 2 still suffers from gait ataxia. LESSONS CFE can rarely occur in various nontraumatic conditions, with or without evident etiology. Furthermore, it may not show characteristic clinicopathological manifestations. Therefore, careful follow up of those who have undergone procedures that are likely to trigger FES or who have hemodynamic or hypercoagulable risk factors is needed.

Abstract
BACKGROUND Large fat embolus is a rare but potential reversible cause of ischaemic stroke. METHODS AND RESULTS We describe the neurosurgical management of a complete right internal carotid artery occlusion due to a large fat embolus, caused by a mitral valve replacement. CONCLUSION Knowledge of acute cerebral ischaemia due to large fat embolism and its hallmark 'hypodense artery' is mandatory. Extracranial to intracranial bypass is a feasible rescue treatment after failure of endovascular embolectomy.

Abstract
Facial fat grafting is increasing worldwide. Although there are few reports in the literature on complications following facial lipofilling, rare but serious complications include embolic risk to local end organs such as the skin and eye, and the central nervous system. Treatment strategies are outlined. The key to prevention of complications is understanding the regional anatomy. It is imperative to adhere to the safe and efficacious techniques to minimize risk. Every surgeon who performs facial fat grafting should establish a systematic method to deliver safe, consistent, and long-term results for their patients.
