A new sheath comprising three circular plastic tubes which slide concentrically over each other is described. Since there is no step in the direction of introduction, an atraumatic vessel-puncture is possible.
Osteoid-osteoma is a frequent benign tumor of the bone. In cases with peri- or intraarticular localisation symptoms suggestive of arthritis may occur. We report on a 25-year-old patient with a painful hip during exercise as well as in the night. Conventional radiographs were unremarkable. However, ultrasound and computertomography revealed joint effusion of the hip. Scintigraphic and tomographic findings were compatible with an osteoid osteoma. Histology of the surgically removed tumor confirmed this diagnosis. Moreover, a lympho-follicular synovitis was found.
Sialography is at present performed either by the subtraction mode or conventional technique only. We utilised a high-resolution digital radiography system with a 1024 x 1024 matrix in 17 patients with diseases of the salivary glands. Digital subtraction ductography in lateral projection was followed by digital radiography in adequate projections. In that way advantages of both methods could be combined in one. Additional advantages are possibilities of storage and communication of the digital data.
