[Diagnostic percutaneous thoracic punctures. Assessment through a critical study of a compliation of 2406 cases]. / Ponctions thoraciques percutanées à visée diagnostique. Mise au point à partir de l'étude critique d'une expérience de 2406 cas.

The aim of this retrospective study of 2,406 diagnostic percutaneous thoracic needle aspirations under computer tomographic control was to assess the diagnostic value of this method, the technical problems and the complications and finally, to refine the indications. Percutaneous needle aspiration had been carried out after negative fibreoptic bronchoscopy. The authors review their technique and show the value of biopsy material which is only slightly traumatised. Computerised tomography and fine needle aspiration reduce the risk of pneumothorax and haemorrhage in a significant fashion. Personalized collaboration between the radiologist, physician and cytologist is a vital pre-requisite. The indications are discussed notably in cases of solitary pulmonary nodules and of mediastinal masses.
