[Instrumental technics of exploration of the mediastinum].
Several techniques can be used for the diagnosing of diseases pertaining to the mediastinum. The diagnosis can be made in 78% of cases by mediastinoscopy. When the lesion is situated beyond the reach of mediastinoscopy, needle biopsy and pleuroscopy can be used either alone or associated to mediastinoscopy. The histological diagnosis can be made in almost all cases. But a few precautions are necessary because this technique carries a certain risk for vessels. Therefore preoperative angiography of the superior vena cava or arteriography of the branches of the aortic arch should be performed to help for the diagnosis and ensure its safety.
