[Angiographic localisation diagnosis via intra-arterial cytostasis catheters for the perfusion of orocavitary and pharyngeal tumours (author's transl)].

Correct positioning of the intra-arterial vascular catheter is essential for the technical execution of a fractionated, locally-acting (as far as possible) perfusion of medicaments with a minimum of side effects--now that selective chemotherapy has been introduced as part of a multi-method treatment of tumours in the head and neck region. For this purpose, angiographic imaging of the catheter topography with the relevant dependent vascular area is recommended. This procedure is relatively easy and allows immediate correcting of the catheter position, while taking into consideration the individual blood flow conditions. In a group of 70 patients subjected to this procedure by the author, no local complications were seen.
