Establishing a reliable central venous access is an important procedure in clinical haematology and oncology. The purpose of this study was to determine how anatomical variations in the internal jugular vein (IJV) and its position in relation to the common carotid artery (CCA) in cancer patients affects external landmark puncture. ⋯ External landmark puncture may be difficult in a considerable number of patients since the IJV might not be situated in the presumed location anteriorly or laterally to the CCA, or a normal lumen may not be present in approximately 1/3 of cancer patients. This study supports the use of ultrasound-guided techniques for central venous catheters particularly in haematological and oncological patients.

Up to now, sonography of the thorax has not been taken into consideration in cases of interstitial lung disease because of its technical limitations. This study was aimed at examining pleural and subpleural alterations in cases of interstitial lung disease and comparing the sonographic method with the usual imaging procedures such as x-ray and computer tomography. ⋯ Sonography of the thorax has proved to be an excellent complementing examination method in cases of interstitial lung disease. The advantages lie in the possible detection of small pleural effusions and small subpleural infiltrations, where this method can also be used to monitor therapy.
