Retrosternal (intrathoracic) goitre--diagnosis and surgical treatment.

For a period of 12 years (1987-1998) 2033 patients underwent surgical treatment of the thyroids in the surgical clinics of the Higher Medical Institute in Plovdiv. Retrosternal or intrathoracic goitre was found in 29 patients (p +/- Sp = 1.43 +/- 0.26%). Of these, seven were males and 22 females all aged 32 to 76 years. Twenty two of the patients were euthyroid and seven hyperthyroid (75.9 +/- 7.9% and 24.1 +/- 7.8%, respectively). Compression of adjacent organs was detected in 19 of the patients (65.5 +/- 8.8%) (P < 0.05). X-ray, ultrasonography, scintigraphy (gamma-chamber), computed tomography, and in cases of voice disorders, direct laryngoscopy were used in making the diagnosis. All patients underwent surgical treatment. Cervical collar incision was suitable in 27 patients and in one patient longitudinal sternotomy was used and in other, who had deep posterior mediastinal goitre, Hart's method of combined thoracotomy and cervicotomy was required. The weight of the resected glands varied from 50 to 1500 g. The results obtained are discussed in terms of the incidence, type, and site of the retrosternal (intrathoracic) goitre, capabilities of the contemporary methods of diagnostics, surgical necessities, surgical approach and compared with literature data.

[Transclavicular approach for delivery of intrathoracic giant goiter. An alternative surgical option].

To remove the immerse portion of a cervical goitre it is necessary to treat preventively the cervical thyroid arteries. In most cases it is afterwards it is easy the blunt finger dissection of the mediastinal bulk following the correct cleavage plane and its dislodging in the cervical area. But in very rare instances, according also to the personal experience, remains some difficulty for the passage of a too bulky and hard mediastinal mass through the rigid limits of the upper thoracic outlet, or the immerse struma is too fragile for pulling it by transfixion threads. Therefore, traditionally arises the opportunity of an additional surgical access, through the breastbone or through the thoracic wall, according to the circumstances. Our experience, completely occasional but extremely positive of two of such cases, induces us to advance a proved alternative surgical proposal. When the difficulty of the removal of the immerse portion of the goitre comes only from the incongruence of the immerse volume and the rigid limits of the upper thoracic outlet, our proposal is that to obtain an amplification of the narrow passage breaking the continuity of the clavicle, by its section beneath the periostium near the breastbone and removing this sternal stump from the joint. The result is that of an widening of the upper thoracic outlet, no more rigid, and making easy the transit of the immerse portion from anterior mediastinum so dislodged in the neck. The rationale of this choice is that all is requested in such cases is only to overcome the obstacle of the incongruence among volume and bulk of the immerse portion and the bone limits fixed from the narrow upper thoracic outlet. Both the traditional sternotomy and the thoracotomy seems disproportional for this purpose, moreover with additional problems during the operation. The true advantage of these classical solutions is in treating under direct vision the anomalous arteries of the mediastinal goitre in cases of ectopic localization. But this is not the case of an immerse cervical goitre. It is therefore essential to note that this proposal applies only to the migrated goitre and not to the ectopic ones. The recovery is extremely simple, and both the aesthetics and the static of the scapular joint are not substantially compromised.

Posterior mediastinal goiter.

A patient with chronic cough and recent dysphagia was found to have a retrotracheal mass extending into the mediastinum on chest radiography. A computed tomographic scan confirmed a retrotracheal posterosuperior mediastinal lesion which was believed to have a neurogenic origin. A thyroid 131I scan revealed no uptake of tracer in the chest and results of thyroid function tests were normal. A large retrotracheal colloidal nodular goiter was excised through a right thoracotomy. The diagnostic approach and the safety of surgical access by thoracotomy for thyroid lesions in this unusual site are discussed.

[A case of ascending aortic aneurysm with intrathoracic goiter].

A case of the successful operation for ascending aortic aneurysm and intrathoracic goiter was described. A 71-year-old woman was admitted to our hospital for the treatment of ascending aortic aneurysm disclosed by the examination in another hospital. Preoperative chest CT showed ascending aortic aneurysm as large as 8 cm in diameter, and an upper mediastinal tumor compressing the main bronchus. The tumor was continuous with the right lobe of the thyroid. The excision of the tumor was performed through median sternotomy with cervical collar incison. After that, the replacement of the ascending aorta was carried out under cardiopulmonary bypass and hypothermic circulatory arrest. The histological examination of the resected specimen revealed adenomatous goiter without malignancy.

[Diagnosis and therapy of patients with euthyroid goiter].

Nontoxic goitre is common, even in areas where iodine intake is sufficient. The most important symptoms and signs of nontoxic goitre are caused by compression of vital structures in the neck or upper thoracic cavity. In any patient with goitre the serum concentration of thyroid-stimulating hormone (TSH) should be measured to detect or exclude clinically inapparent (subclinical) hyper- or hypothyroidism. CT and MRI are expensive but very sensitive methods to identify tracheal compression and to determine intrathoracic extension. Thyroid ultrasonography and scintigraphy are not routinely indicated. Fine-needle aspiration biopsy is indicated in patients with fast-growing nodules and nodules that have a firmer consistency than other nodules within the gland. Thyroidectomy is standard therapy for young and otherwise healthy patients, especially when prompt decompression of vital structures is required. Radioiodine therapy is an attractive alternative to surgery in older patients, in those with cardiopulmonary disease, and in those with recurrent goitre. Thyroxin therapy may be tried in young patients with small, diffuse goitres who have normal serum TSH concentrations.

[Diagnosis of intrathoracic goiter].

The various aspects of the diagnosis of intrathoracic goitre are examined. Clinical, blood chemistry and radiological and radioisotope data are required before a firm decision can be made. Detailed recognition of goitre type and assessment of the site and extent of the intramediastinal portion, together with determination of the existence of intra- and extraparenchymal inflammation or degeneration or other signs of disease, are an essential differential overture to the choice of a surgical approach route (cervical, cervical-mediastinal with median sternotomy, transthoracic) and the appraisal of prognosis. In the absence of malignant degeneration, prognosis is good in all cases, since this type of goitre can be completely and finally eradicated.

[Intrathoracic goiter].

AIM: A goiter, situated partly or on completely in the thoracic cavity is usually referred to as intrathoracic goiter (ITG). However, inadequate definition of intrathoracic malpositions of thyroid gland caused usage of different classifications. This produced different and, often unclear criteria for the grouping of intrathoracic thyroid malpositions and, consequently, very different results and difficulties in any attempt of parallel review or analysis. The aim of this research was to analyze the ITG that include goiters with more than 80% of tissue in the thoracic cavity and intrathoracic thyroid choristomas, and to point out the diagnostic problems and surgical dilemmas. METHODS: Source of the used data were the studies published in the last 50 years in English, French, Italian, German and Russian language. Data have been integrated and combined for the detailed analysis, while quantitative synthesis was achieved by statistical analysis. RESULTS: ITG was represented in 1% of operatively treated thyroid diseases. One third of patients were asymptomatic. Commonly observed symptoms were dyspnea, stridor and dysphagia, and there was no significant difference in appearance of these symptoms between the two groups of ITG. Chest roentgenography and CT scan could provide the maximal information with no need for expensive procedures. Accuracy of scintigraphy in revealing and discerning of ITG is 70%, averagely. In 20% of patients correct preoperative diagnosis was not established. Therapy of choice in the treatment of ITG was surgical, even in asymptomatic cases. Thoracic approach was used in 95% of cases and there was no significant difference between the two groups of ITG. Total thyroidectomy or total lobectomy was definitely obligatory with contralateral subtotal lobectomy. There was no significant difference in the frequency of operative complications between ITG and non-ITG, and between the two groups of ITG. CONCLUSIONS: ITG is rare, but might present a difficult diagnostic and complex surgical problem. Common clinical presentation and identical surgical approach in operative treatment justify the common review of the two groups of ITG. With timely and adequately performed surgical approach, in specialized institutions, frequency of complications in operative treatment of ITG was not higher if compared to operative treatment of non-ITG.

Life-threatening giant mediastinal goiter: a surgical challenge.

Mediastinal goiter is a well known benign disease, usually resectable through a cervical approach with minimal morbidity and mortality. Only occasionally a median sternotomy or a lateral thoracotomy may be required. The present case is worthy of presentation because of the exceptional dimension of the disease and the surgical challenge that it presented. In a 72-year-old woman a large intrathoracic goiter of the right thorax caused a severe dyspnoea due to an important contralateral mediastinal shift with compression of the lung, superior vena cava system and trachea. At surgical exploration, through a cervico-sternotomic approach, the mediastinal structures dislocation and the strong adherences between the anomalous neovascularized capsula of the mass and the surrounding structures, complicated the surgical dissection. An accidental lesion of the innominate artery required its reimplantation on the ascending aorta. An immense mass, was finally removed and pathological examination revealed a rare case of neovascularized, pseudosarcomatoid capsula among a benign hyperplastic proliferation. In spite of its benign nature, a giant goiter caused a life-threatening compression of the respiratory tract and lung parenchyma in this patient. The dimension of the lesions, the mediastinal anatomy alterations and the severe intraoperative haemorrhage represented major technical difficulties during surgical resection.

[Acute respiratory insufficiency caused by plunging goiter (author's transl)].

Acute respiratory insufficiency and unconsciousness are symptoms which may lead to misinterpretation. In cases of unclear acute respiratory insufficiency one should think of the rare plunging goiter with acute tracheostenosist, especially in female patients over 40 years. Diagnosis can easily be found if the patient is thoroughly observed. Resection of the retrosternal struma is the only possible therapy. One case of plunging goiter is described here.
