[Demonstration of complications caused by implantable catheter systems in regional arterial infusion therapy of tumors of the pelvis (bladder cancer). Radiologic and nuclear medicine control possibilities].

Loco-regional intra-arterial infusion chemotherapy is gaining momentum in modern tumor therapy. Cytostatica are delivered by an implantable system. Because of high tissue toxicity of chemotherapy functioning of the system must be assured and controls should be simple and reliable. The system implanted in 10 pat. with bladder-cancer (p T3 a-b) was checked by radiological and radionuclide diagnostic means before each chemotherapy. Both techniques proved valuable. Good and deficient functions are demonstrated.
