[Digital subtraction angiography].

Between 10 February 1983 and 9 November 1984 482 patients were investigated by digital subtraction angiography, mainly for carotid arterial disease and problems associated with transplanted kidneys. The use of abdominal compression and antispasmodics are essential to minimize bowel artefacts for intraabdominal arterial examinations. The apparatus is advantageous for interventional radiologists. Images are immediately seen, can be stored on analogue tape, digitalized and obtained with smaller volumes of contrast medium and without arterial catheterization. Movement artefacts, however, can cause problems.
