Sclerotherapy of benign oral vascular lesions with non-diluted ethanolamine oleate / Escleroterapia de lesiones vasculares orales benignas con oleato de etanolamina no diluido

Benign oral vascular lesions are anomalies characterized by the blood vessels proliferation or malformation and the treatment with the sclerosing agent ethanolamine oleate acts irrigating the vessel producing a sterile inflammatory response. The objective of this study was to report and discuss the results from treatment of benign oral vascular lesions with non-diluted ethanolamine oleate through the analysis of clinical records. The sample was composed by the selection of twenty-six patients (12 male and 14 female), with oral vascular malformations. All lesions were treated with intralesional injections of undiluted ethanolamine oleate. These patients attended in Oral Medicine outpatient clinic of the Federal University of Paraná between the years of 2011 to 2015. The average age was 60.65 years, with a higher prevalence for women. The majority of the individuals had one lesion and its location was mostly in the lower lip. The main complaint was about a physical discomfort. The lesions had the average size of 6.52 mm and received a median number of 2.32 applications. Only one patient reported feeling pain in the postoperative week. In most cases the resolution of the lesion was considered partial. Follow-up was obtained up to one month after the end of treatment. The sclerotherapy with undiluted ethanolamine oleate shows acceptable results in the treatment of small benign oral vascular lesions with a few minor side effects.

Las lesiones vasculares orales benignas son anomalías caracterizadas por la proliferación o malformación de los vasos sanguíneos y el tratamiento con el agente esclerosante etanolamina oleato actúa irrigando el vaso produciendo una respuesta inflamatoria estéril. El objetivo de este estudio fue informar y discutir los resultados del tratamiento de lesiones vasculares orales benignas con oleato de etanolamina no diluido a través del análisis de historias clínicas. La muestra estuvo compuesta por la selección de veintiséis pacientes (12 hombres y 14 mujeres), con malformaciones vasculares orales. Todas las lesiones fueron tratadas con inyecciones intralesionales de oleato de etanolamina sin diluir. Estos pacientes acudieron a la clínica ambulatoria de Medicina Oral de la Universidad Federal de Paraná entre los años 2011 a 2015. La edad promedio fue de 60,65 años, con una mayor prevalencia para las mujeres. La mayoría de los individuos tenían una lesión y su ubicación era principalmente en el labio inferior. La queja principal era sobre una molestia física. Las lesiones tenían un tamaño promedio de 6,52 mm y recibieron una mediana de 2,32 aplicaciones. Solo un paciente informó haber sentido dolor en la semana postoperatoria. En la mayoría de los casos, la resolución de la lesión se consideró parcial. El seguimiento se obtuvo hasta un mes después del final del tratamiento. La escleroterapia con oleato de etanolamina sin diluir muestra resultados aceptables en el tratamiento de pequeñas lesiones vasculares orales benignas con algunos efectos secundarios menores.

Sclerotherapy as an esthetic indication in oral vascular malformations: a case series

Abstract Background The use of monoethanolamine oleate 5% is effective for the treatment of vascular malformations with low blood flow. Objectives To report a case series of vascular malformations in the mouth and oral cavity treated with monoethanolamine oleate 5%. Methods A retrospective descriptive study was performed in electronic patient charts covering seven years. Patient demographics, diagnostic resources, lesion site, size, and number of applications of monoethanolamine oleate 5% were collected. Results A total of 21 vascular malformations were recorded, located mostly on the lower lip (52.3%) and resolved in a single application in 14 patients. The authors found 19 patients treated with sclerotherapy. Thirteen were women and six were men, with a mean age of 61 years. Study limitation Small sample size. Conclusions Sclerotherapy is an effective treatment for vascular malformations of the lips and oral cavity, with resolution after only one or two applications (n = 16).

Fístula de artéria coronária direita com o tronco da artéria pulmonar como causa incomum de síncope em pacientes idosos / Fistula between the right coronary artery and the branch of the pulmonary artery as an uncommon cause of syncope in elderly patients

Fístulas de artérias coronárias são incomuns e caracterizam-se como conexões diretas, provenientes de ambas artérias ou de apenas uma delas, com outra estrutura. Quando de baixo débito, tendem a comunicar-se com qualquer uma das câmaras cardíacas ou com vasos cardíacos adjacentes. No entanto, comunicações com o tronco pulmonar são raras e subdiagnosticadas, visto que grande parcela dos pacientes é assintomático ou possui sintomas inespecíficos relacionados ao quadro. Nesse relato de caso, apresentamos uma paciente com histórico recorrente de síncope, que iniciou acompanhamento clínico em ambulatório de geriatria e gerontologia, cuja investigação suscitou diagnóstico de causa cardíaca subjacente como etiologia dos episódios. (AU)

Coronary artery fistulas are uncommon and are consist in direct connections from both arteries or just from one of them with other structure. When they have low output, they usually tend to communicate with any of the cardiac chambers or other adjacent cardiac vessels. However, communications with the pulmonary trunk are rare and underdiagnosed, since most of patients are asymptomatic or have nonspecific symptoms related to the condition. In this report, we describe and discuss the case of a patient with a recurrent history of syncope, that started clinical follow-up in an ambulatory of geriatric and gerontology, whose investigation lead to the identification of an underlying cardiac cause as the etiology of the episodes (AU)

Ethanol sclerotherapy of head and neck venous malformations / Escleroterapia com etanol em malformações venosas da cabeça e pescoço

Objective This retrospective study evaluated the results of sclerotherapy with low doses of ethanol for treatment of head and neck venous malformations. Methods We treated 51 patients, 37 females. Median age was 23 years. Patients were treated with percutaneous intralesional injection of alcohol every two weeks and followed up prospectively for a median period of 18 months. Most lesions affected the face and cosmetic disfigurement was the most frequent complaint. Results We performed a median of 7 sessions of sclerotherapy. Complete resolution or improvement was observed in 48 patients presented. Five cases of small skin ulceration, two cases of hyperpigmentation and two of paresthesia were documented; all of them were treated conservatively. Conclusion Percutaneous sclerotherapy with low doses of ethanol is a safe and effective treatment modality for venous malformations affecting the head and neck. .

Objetivo Estudo retrospectivo que analisou os resultados da escleroterapia, com doses baixas de etanol, realizada sob anestesia local para tratamento de malformações venosas na cabeça e pescoço. Métodos Foram tratados 51 pacientes, sendo 37 do gênero feminino. A mediana de idade foi de 23 anos. Os pacientes foram tratados com injeções alcoólicas nas lesões, por via percutânea, em sessões quinzenais, e acompanhados prospectivamente por um período mediano de 18 meses. A maioria das lesões acometia a face e a queixa principal mais frequente foi deformidade estética. Resultados Foram realizadas, em média, sete sessões de escleroterapia. Resolução completa ou melhora foi observada em 48 pacientes. Cinco pacientes apresentaram pequena úlcera cutânea, dois hiperpigmentação e dois parestesia, sendo todos tratados conservadoramente. Conclusão A escleroterapia percutânea com doses baixas de etanol é um método seguro e eficaz para tratar malformações venosas na cabeça e pescoço. .
