The aim of this study was to analyze the results of 17 patients with myasthenia gravis who, from 1985 to 1994, were submitted to thymectomy at the Medical School of Santa Casa de São Paulo. Nine patients (52.9%) were female and the mean age was approximately 30.3 years. The most usual symptoms were ptoses, weakness, and diplopia. Other symptoms included: dyspnea, dysphonia, thoracic pain and loss of weight. The average development period of the disease was 17.5 months (between 3 and 96 months). The diagnostic methods use were chest X-ray, response to edrophonium chloride (Tensilon), electrophysiologic study and thoracic CT. All patients were submitted to thymectomy through medium sternotomy. Patients were followed up from one month to ten years. Only one patient did not return to the clinic. Twelve patients (75%) achieved good results. The others four patients presented little or no response after thymectomy.

Ten surgeries have been performed on 8 patients for the relief of symptoms due to bullous disease. Closed intubation drainage of the bullae was used in all patients under local anesthesia. The technique, initially devised by Monaldi for the treatment of intrapulmonary tuberculous abscesses was modified. Symptomatic improvement and total collapse of the bullae was reported by 9 of the 10 procedures. The technique described provides a simple method for decompressing bullae by means of a minimally invasive surgical procedure. It has proved a suitable approach for all but those with the poorest lung function and is now the author's treatment of choice. Techniques using intracavitary intubation have potential advantages: no lung tissue is removed, in addition, the limited incision and a local anesthesia needed for the procedure are better tolerated by patients with poor lung function.

Objetivo: Descrever a técnica operatória da drenagem pulmonar através do estudo anatômico em cadáveres, determinar se o local definido para a drenagem pulmonar é adequado e seguro, e determinar a relação anatômica do tubo de drenagem com a parede torácica, pulmões, grandes vasos e mediastino. Métodos: Foram dissecados 30 cadáveres de ambos os sexos, fornecidos pelo Necrotério do Hospital Central da Santa Casa de São Paulo, em São Paulo (SP) no período entre maio e novembro de 2011. Foi inserido um dreno de aço de 7,5 cm com 24 F de diâmetro no segundo espaço intercostal, na linha médio-clavicular, bilateralmente, e foi medida a distância do dreno com as seguintes estruturas: brônquios principais, brônquios dos lobos superiores, vasos subclávios, artérias pulmonares, artérias pulmonares do lobo superior, veia pulmonar superior, veia ázigos e aorta. Foram realizadas medições de peso, altura, diâmetro laterolateral do tórax, diâmetro posteroanterior do tórax e espessura da parede torácica de cada cadáver. Resultados: Dos 30 cadáveres dissecados, 20 e 10 eram do sexo masculino e feminino, respectivamente. A média da extremidade distal do dreno com os brônquios principais direito e esquerdo foi de 7,2 cm. Conclusões: A utilização de um dreno torácico de tamanho fixo na posição preconizada é factível e segura, independentemente das características antropométricas do paciente.
