An intra-arterial chemotherapy procedure in patients with malignant tumours in the oral and maxillo-facial region which, from the vascular point of view, can be dependent on the external carotid artery and/or its branches is presented. Particularly for the prevention of catheter infection, obstruction, etc., a subcutaneous pouch, connected to the infusion catheter, is implanted subcutaneously in the submastoid region.
