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

Full-thickness scalp defects exposing the skull can be challenging for plastic surgeons. Scalp skin has low elasticity, so a large flap is necessary to cover even a small defect. This article presents 9 cases in which 3 rhomboid flaps were used for the c1osure of scalp defects. One patient experienced flap necrosis and required reoperation. Two other patients had minor complications treated with dressing. The method presented here in allows the harvest of 3 small flaps that collectively cover the defect as well as the primary closure of the donor area. This technique does not require the creation of a large fiap or skin graft from the donor. Thus, the technique described here in is suitable for medium-thickness scalp defects and is a good alternative to large rotation fiaps and skin grafts.


Defeitos no couro cabeludo podem ser um desafio para os cirurgiões plásticos quando afetam sua espessura total e deixam o crânio exposto. O couro cabeludo tem pouca elasticidade,assim um grande retalho é necessário para cobrir um defeito pequeno. O objetivo deste artigo é apresentar 9 casos em que 3 retalhos romboides foram utilizados para o fechamento de defeitos no couro cabeludo. Um paciente apresentou necrose do retalho e foi necessária reoperação. Dois outros pacientes tiveram complicações menores, que foram tratadas com curativos. O método apresentado permite a confecção de 3 pequenos retalhos que em conjunto cobrem o defeito, e as áreas doadoras são fechadas primariamente. Com a utilização da técnica descrita, a confecção de um retalho grande e a enxertia de pele da área doadora não são necessárias. Neste artigo é descrita uma técnica para fechamento de defeitos de tamanho moderado no couro cabeludo, que é uma boa alternativa a grandes retalhos de rotação ou enxerto de pele.

ABSTRACT

INTRODUÇÃO: A monitorização do retalho livre após a cirurgia é de vital importância, especialmente nas primeiras horas de pós-operatório, pois o momento de reabordagem pode ser o definidor entre o salvamento ou a perda do retalho. Até o momento, não existe trabalho na literatura estudando a decisão de abordagem do retalho baseada em medidas objetivas ou a comparação da glicemia entre retalhos que evoluíram bem com os que sofreram sofrimento vascular. O objetivo deste estudo é avaliar a validade da medida da glicemia capilar do retalho como método de monitorização de retalhos microcirúrgicos comparando com a avaliação clínica. MÉTODO: Foram estudados prospectivamente 16 pacientes portadores de retalhos livres, realizados de maio de 2012 a julho de 2012. A glicemia capilar foi avaliada por equipe formada por profissionais não envolvidos com a cirurgia realizada. A avaliação clínica do retalho foi realizada no pós-operatório imediato, na chegada à UTI, a cada 3 horas e sempre que necessário. RESULTADOS: Dos 16 pacientes, 5 (31,3%) apresentaram complicações nas primeiras 24 horas. Todas as complicações observadas foram trombose venosa. Foi observada diferença estatisticamente significante na glicemia capilar de portadores de retalhos que apresentaram trombose venosa em comparação àqueles que não tiveram a complicação, nas medidas realizadas 6 horas, 9 horas e 12 horas após a operação (P < 0,05). CONCLUSÕES: A medida da glicemia capilar não foi superior à avaliação clínica por profissional experiente na detecção de trombose venosa de retalhos livres.


BACKGROUND: Monitoring of free flaps after surgery is vitally important, especially in the first few hours because the timing of reoperation can determine flap salvage or loss. To date, no study has examined the decision to reoperate on a flap based on the objective measure of glycemia or a comparison between flaps that showed good outcomes and those that showed vascular damage. The objective of this study was to evaluate the validity of blood glucose measurements within the flap as a method for monitoring free flaps and to compare the efficacy of this method with that of clinical assessments. METHODS: The study was prospective, included 16 patients with free flaps, and was conducted from May 2012 to July 2012. A team of professionals not involved in the surgery evaluated capillary glycemia. Flaps were clinically evaluated during the immediate postoperative period, on ICU admission, at every 3 hours, and as needed. RESULTS: Of the 16 patients, 5 (31.3%) had venous thrombosis in the first 24 hours. Statistically significant differences were noted in capillary glycemia in patients with or without venous thrombosis in measurements obtained 6, 9, and 12 hours after surgery (P < 0.05). CONCLUSIONS: The measurement of capillary glycemia was not superior to clinical evaluation by an experienced professional for the detection of venous thrombosis within free flaps.

ABSTRACT

OBJECTIVE: Serial C-reactive protein measurements have been used to diagnose and monitor the response to therapy in patients with pneumonia and other infectious diseases. Nonetheless, the role of C-reactive protein measurement after surgical treatment for pleural empyema is not well defined. The aim of this study is to describe the behavior of C-reactive protein levels after the surgical treatment of pleural empyema and to correlate this parameter with the patient's prognosis. METHODS: We retrospectively analyzed the records of patients with pleural empyema treated by either chest-tube drainage or surgery from January 2006 to December 2008. C-reactive protein levels were recorded preoperatively and 2 and 7 days postoperatively. The clinical outcome was binary: success or failure (mortality or the need for repeated pleural intervention). RESULTS: The study group comprised fifty-two patients. The median C-reactive protein values were as follows: 146 mg/L (pre-operative), 134 mg/L (post-operative day 2), and 116 mg/L (post-operative day 7). There was a trend toward a decrease in these values during the first week after surgery, but this difference was only statistically significant on day 7 after surgery. Over the first week after surgery, the C-reactive protein values decreased similarly in both groups (successful and failed treatment). No correlation between the preoperative C-reactive protein level and the clinical outcome was found. CONCLUSIONS: We observed that, in contrast to other medical conditions, C-reactive protein levels fall slowly during the first postoperative week in patients who have undergone surgical treatment for pleural empyema. No correlation between the perioperative C-reactive protein level and the clinical outcome was observed.
