ABSTRACT
Introdução: O lábio é a região do corpo mais frequentemente acometida por anomalias vasculares (AV). A correta determinação da etiologia da lesão é determinante à escolha do tratamento do paciente e à correta condução do caso. O objetivo deste estudo é correlacionar o posicionamento anatômico e as características das lesões com o diagnóstico etiológico das AVs dos lábios, a fim de promover uma ferramenta que auxilie na prática clínica. Métodos: Análise retrospectiva de 150 pacientes com AV dos lábios, avaliados entre 1999 e 2017. O diagnóstico etiológico foi baseado na classificação de ISSVA 2014. Análise clínica e fotográfica foi realizada para avaliar o padrão anatômico de envolvimento e mapear as lesões. Resultados: Hemangioma infantil apresentou acometimento de apenas um lábio, em menor extensão e situado mais centralmente, com raro envolvimento de comissura oral. Malformações venosas e venolinfáticas (MVs) e malformações arteriovenosas (MAVs) envolveram o lábio superior predominantemente, situadas mais lateralmente e acarretando significativa deformidade. Contudo, MAVs apresentaram mais frequente extensão além dos limites do vermelhão. Os pacientes com malformações capilares (MCs) sofriam de acometimento integral do lábio inferior. Todos os casos de malformações linfáticas exclusivas (MLs) envolveram o lábio superior inteiro, com grande distorção. Conclusão: A apresentação inicial das AVs muitas vezes consiste em pequenas alterações, desafiadoras ao diagnóstico assertivo. Padrões específicos de acometimentos foram observados para cada diagnóstico etiológico estudado. O mapeamento pode ser utilizado como ferramenta auxiliar diagnóstica e contribuir para melhor intervenção nos pacientes com anomalias vasculares labiais.
Introduction: The lip is the body region more often affected by vascular anomalies (VAs). Identifying the appropriate etiology of the lesion is significantly important when determining the treatment of choice for the patient. This study aimed to determine the association between the anatomical positioning and the characteristics of the lesions and the etiological diagnosis of VAs of the lips to identify the appropriate tool to be used in clinical practice. Methods: A retrospective analysis was performed in 150 patients with VA of the lips evaluated between 1999 and 2017. The etiological diagnosis was based on the International Society for the Study of Vascular Anomalies 2014 classification. Clinical and photographic analysis was performed to assess the anatomical pattern of involvement and map the lesions. Results: An infantile hemangioma was observed to a lesser extent in only one lip and was situated more centrally, with rare involvement of the labial commissure. Venous and venous-lymphatic malformations and arteriovenous malformations (AVMs) involving the upper lip were predominantly located more laterally and caused significant deformity. However, AVMs more often extended beyond the limits of the vermilion. Capillary malformations were observed in the entire lower lip in some patients. Simple lymphatic malformations were observed in the entire upper lip with significant distortion in some patients. Conclusion: The initial presentation of VAs often comprises minimal changes; hence, establishing an assertive diagnosis is considered difficult. Specific patterns of involvement were observed for each etiological diagnosis studied. Anatomical mapping can be used as an auxiliary diagnostic tool and can possibly identify an appropriate clinical intervention in patients with VAs of the lip.
ABSTRACT
OBJECTIVE: Arteriovenous malformations (AVM) of the ear show unique features. Progressive growth or inadequate management of AVMs may lead to bleeding, infection, cartilage exposure, and ultimately loss of structure. Total ear amputation is an alternative; however, due to the structural complexity of the ear, reconstruction is technically challenging. This study presents a treatment algorithm based on a clinical series, with treatment options including resection and immediate and late reconstruction. METHODS: Between 2004 and 2018, 12 patients with auricular AVMs were treated with AVM resection and ear reconstruction at our hospital. Among these 12 patients, seven were women, and patients' ages ranged between 4 and 34 years. Parameters considered before resection and reconstruction were compromised ear extension (partial, total, or extra-auricular involvement), thickness (cutaneous and cartilaginous), symptoms (bleeding, infection, ulceration, and/or cartilage exposure), and preoperative embolization. Total resection of AVMs was planned as the first step in all cases, followed by primary closure. AVM resection was categorized into a partial or total procedure, resulting in partial or total ear defects. Reconstruction was categorized as immediate or delayed. RESULTS: Preoperative embolization was performed in 10 patients. AVMs were totally removed, resulting in seven total ear amputations. In six of these patients, total ear reconstruction was performed 6 months later, and all patients were recurrence-free. Only one patient did not undergo ear reconstruction. Regrowth was not observed in any reconstructed ear. CONCLUSION: Treatment of ear AVMs requires a planned approach to achieve favorable clinical outcomes and for concomitant safe and definitive reconstruction.
