[Transparietal puncture aspiration biopsy of the lung and mediastinum].

BACKGROUND: The contribution of fine needle transparietal aspiration biopsy for the diagnosis of diseases of thoracic organs is generally accepted. The objective of the present study is to evaluate the contribution of this method to the diagnosis of processes in the lung and mediastinum. METHODS AND RESULTS: Transparietal fine needle aspiration biopsy was performed in 115 patients, 75 men and 40 women, mean age 59 +/- 10.7 years in men and 58.4 +/- 10.3 years in women. The site of insertion and position of the needle were checked by skiascopy. The assembled material was evaluated cytologically under a light microscope. Malignant tumours were classified according to WHO recommendations. The greatest diagnostic yield of the method was in a group of 73 patients with clinical suspicion of a malignant process; this suspicion was confirmed by cytological examination in 50 patients, i.e. in 68.5% of the patients. In 7 of 15 patients with suspected tuberculosis cytological evidence of epithelioid and Langerhans cells supported the diagnosis of pulmonary tuberculosis; from four punctures of mediastinal formations confirmed a malignant tumour in half of them. In a relatively large group of patients with inflammatory processes the cytological finding did not prove useful for establishment of the diagnosis. Complications of this examination in the whole group were recorded in 18 patients (15.6%). The most frequent complication was the development of pneumothorax (18 patients, 15.6%) which however, only in 2 patients required exsufflation. In three patients after the procedure minimal haemoptysis developed. CONCLUSIONS: Complications, although fairly frequent (15.6%), are not serious.

[Symptoms of diseases of the respiratory system and their importance in diagnosis. Summary and conclusions of research].

The status in the sphere of diagnosis of respiratory diseases and the revealed shortcomings in this area stimulated workers of the First Clinic for TB and Respiratory Diseases to elaborate two investigations, the aim of which was to reveal in the course of the eighties (1983-1988) the most important problems in the diagnostic process and thus contribute to the improvement of the present state. Another task was to record developmental trends as regards the contents of the discipline of pneumology. A relatively large number of patients (2207 subjects) and the period of investigation made it possible to draw some general conclusions. The results proved persisting shortcomings, in particular a slow diagnostic process which e.g. in bronchogenic carcinoma and some other diseases very much restricts effective treatment and in TB there is the danger of infection of the healthy population. From this ensue necessary provisions at all levels of medical care (in particular comprehensive examinations of patients, interdisciplinary collaboration, improved preventive provisions and attention paid to changes in the frequency and clinical picture of lung diseases as a result of different factors).

[The role of digital subtraction angiography in the diagnosis of pulmonary anomalies].

The authors evaluate the importance of pulmonary digital subtraction angiography (DSA) in anomalies of pulmonary tissue, the bronchial tree and vascular pulmonary malformations. In a group of eight patients, comprising unilateral pulmonary hypoplasia, pulmonary cysts, vascular malformations and pulmonary sequestrations, they analyze the asset of DSA and the place of this method in the diagnostic algorithm. Reduction of the invasive and risky character of the examination, lower costs, the possibility of immediate evaluation and subsequent processing of the picture and modification of the length of the record is one of the main advantages, as compared with classical angiography.

[The significance of digital subtraction angiography in diseases of the lungs and mediastinum].

The authors present their first experience with lung DSA in a group of 75 patients. The examination was most frequently performed by instilling a contrast medium into central, less frequently into peripheral veins. The most frequent indications included tumorous lung diseases and mediastinal tumours before an operation treatment, a suspected pulmonary embolism, lung and vascular malformation. Intravenous DSA proved to be also useful in the evaluation of pathological changes of thoracic aorta.

[Endobronchial metastases (author's transl)].

The frequency of metastases of solid primary tumors into the respiratory tract is estimated to about 5% by means of bronchoscopic and bronchofibroscopic examinations. The clinical and roentgenological picture of endobronchial metastases in most cases is corresponding to that of a primary bronchial cancer. For differential diagnostics endobronchial metastases have to be delimited from primary bronchial carcinoma, from the multilocular forms of the primary bronchial carcinoma, from benign tumors and pseudotumors of the respiratory tract. The possibility of double tumors (tumorduplicity) must not be forgotten, as well. The endoscopic signs of a benign tumor endobronchially growing are described. However, only the histological or cytologic examination will give certainty. The endoscopic picture of a primary bronchial carcinoma with metastases and other possible multilocular endobronchial alterations are described. In our material the error was most frequent, that the bronchial cancer was confounded with the metastases. During the last 20 years we have observed endobronchial metastases in 22 patients with bronchoscopic methods. In 13 patients an extrapulmonary solid tumor made metastases into the bronchi, breast cancer 4 times, Grawitztumors, adenocarcinoma of the colon, carcinoma of the thymus each two times, cancer of the uterus, of the urinary bladder and the thyroid each one time. In 9 patients autochthonous metastases of a primary bronchial carcinoma were found.
