  • Abstract
  • Look Inside

 Digital subtraction angiography (DSA) was performed through an indwelling catheter inserted into the superficial temporal artery on 22 cases of head and neck cancer. By means of DSA, the tip of the intraarterial catheter can be securely fixed in a short time without giving pain to the patient. In the 22 cases the tip of the catheter was adequately positioned by the conventional indigocarmine dye method. However, it was disclosed by DSA that the catheter was inserted deeper than expected in 4 of them. When observed under DSA, in such cases, the deeply inserted catheter could be easily adjusted to proper position.

 Applications of DSA for estimation of the extent of tumor and evaluation of therapeutic effect were possible in certain cases, but satisfactory results could not be obtained hitherto.
