Introduction and objective: The incidence of endothoracic goiter among patients undergoing thyroidectomy ranges from 6% to 30%. Although the cervical approach is sufficient in most cases, the endothoracic approach may be necessary in 1-5.5% of patients. So it is advisable to anticipate it. The objective of this article is to describe the indications if this kind of approach. Synthesis: The main risk factors for performing sternotomy in cases of substernal goiter are the extension below the aortic arch and the retrotracheal or retrovascular location. The thoracic approach will be equally necessary in mediastinal ectopic goiters without connection to the cervical thyroid. The evaluation by a thoracic surgeon in cases of forgotten goitre will be recommended, as well as in patients with a history of radiotherapy or cervical surgery and suspected malignancy with extra-thyroid involvement. The choice of approach will depend on the location, the size of the mass and its relationship with the neighboring organs. Minimally invasive approaches can be safe alternatives to sternotomy or thoracotomy. The most frequent postoperative complications of endothoracic thyroid resection are typical of thyroid surgery: temporary or permanent recurrent paralysis, hypoparathyroidism, respiratory failure and postoperative bleeding. Conclusions: Up to 5% of thyroidectomies, a thoracic approach may be necessary, so it is convenient to anticipate it. The thoracic approach will be necessary in cases of goiter with extension below the arch, retrotracheal or retrovascular location and in mediastinal goiters without connection to the cervical thyroid., Introducción y objetivo: La incidencia de bocio endotorácico entre los pacientes sometidos a tiroidectomía oscila entre el 6% y el 30%. Aunque el abordaje cervical es suficiente en la mayoría de los casos, el abordaje endotorácico puede ser necesario en el 1-5.5% de los pacientes. Por lo que es recomendable anticiparlo. El objetivo del presente artículo es describir los factores predictivos de necesidad de este tipo de abordaje. Síntesis: Los principales factores de riesgo para la realización de esternotomía en los casos de bocio subesternal son la extensión por debajo del cayado aórtico y la localización retrotraqueal o retrovascular. El abordaje torácico será igualmente necesario en bocios ectópicos mediastínicos sin conexión con el tiroides cervical y se recomendará la valoración por un cirujano torácico en casos de bocio olvidado, así como en pacientes con antecedentes de radioterapia o cirugía cervical y sospecha de malignidad con afectación extra-tiroidea. La elección del abordaje dependerá de la localización, del tamaño de la masa y su relación con los órganos vecinos; los abordajes mínimamente invasivos pueden ser alternativas seguras a la esternotomía o la toracotomía. Las complicaciones postoperatorias más frecuentes de la resección de tiroides endotorácico son típicas de la cirugía tiroidea: parálisis recurrencial temporal o permanente, hipoparatiroidismo, insuficiencia respiratoria y sangrado postoperatorio. Conclusiones: Hasta en un 5% de las tiroidectomías, puede ser necesario un abordaje torácico, por lo que es conveniente anticiparlo. El abordaje torácico será necesario en casos de bocio con extensión por debajo del cayado, localización retrotraqueal o retrovascular y en bocios mediastínicos sin conexión con el tiroides cervical.

Substernal goiter is a relatively rare condition and is estimated to correspond to 7% of all cases of goiter. In most cases it is asymptomatic, but may produce symptons resulting from the compression of contiguous structures. The authors present the case of a 89 year-old woman, with personal history of goiter, admitted in the Emergency Department (emergency room) due to respiratory distress with stridor. The evaluation was compatible with large substernal goiter with deviation and tracheal deformity, presenting an analytical evaluation revealing with hyperthyroidism. The case was discussed with Endocrinologic Surgery medical team and the patient was submitted to total thyroidectomy. This case emphasizes the importance of the rapid integration of data from anamnesis and examination in the approach to a patient in the emergency room, bócio mergulhante é uma patologia relativamente rara e estima-se que corresponda a 7% de todos os casos de bócio. Na maioria dos doentes é assintomático, mas pode produzir sintomas decorrentes da compressão de estruturas contíguas. Os autores apresentam o caso de uma doente de 89 anos, com antecedentes pessoais de bócio, admitida no Serviço de Urgência (sala de emergência) por quadro de dificuldade respiratória com estridor. A avaliação efetuada foi compatível com volumoso bócio mergulhante com desvio e deformidade da traqueia, apresentando avaliação analítica a revelar hipertiroidismo. O caso foi discutido com a equipa de Cirurgia Endocrinológica, tendo a doente sido submetida a tiroidectomia total. Com este caso salienta-se a importância da rápida integração dos dados da anamnese em conjunto com o exame objetivo na abordagem a um doente na sala de emergência

BackgroundSternotomy for substernal goiters (SSG) is associated with greater morbidity than a cervical approach to thyroidectomy. We sought to identify predictors for sternotomy as a surgical approach for the removal of SSG and analyzed the preoperative and postoperative characteristics of patients with SSG compared with those with large goiters contained entirely within the neck or a cervical goiter.MethodsA retrospective review of a surgical database was performed. We included patients with large (>100 g) thyroids or SSG, regardless of size. Between 1995 and 2013, 220 patients met these criteria. Comparisons were made between patients who had an SSG and patients who had a cervical goiter with particular focus on those who required sternotomy.ResultsOf the 220 patients, 127 patients (58%) had SSG, of whom 7 (5.5%) required sternotomy. All patients who underwent sternotomy underwent preoperative computed tomography scanning and were more likely to have preoperative symptoms of chest pressure and voice complaints and have extension of the thyroid gland below the aortic arch. Sternotomy took an average of 2 hours longer than a cervical incision, was associated with significantly more blood loss (600 versus 190 mL, P = 0.04), and a longer length of stay (3.1 versus 1.8 d, P = 0.03) than cervical thyroidectomy.ConclusionsSternotomy for SSG is rare. All patients necessitating sternotomy had extension below the aortic arch and were more likely to present complaining of chest pressure and voice issues.

type:text, A case of substernal goiter is reported. A 78-year-old female was admitted to our hospital with no symptoms. Chest roentgenography on admission showed that a mass of 3 by 5 cm in size with calcification located in the substernal region. Computed tomography of the chest and aortography revealed that the mass was attached to the trachea, but the connection to the great vessels was not clear. Pathological findings of the incisional biopsy specimen showed thyroid tissue with no evidence of malignancy. Our clinical diagnosis was substernal goiter. Surgery was not carried out in this case, based on the literature. Surgery is indicated in case of malignancy or in cases with severe illness such as respiratory disorder and superior vena cava syndrome.
