DSA zur Darstellung tumorbedingter Gefäßveränderungen und Komplikationen bei lokaler Chemotherapie der Leber über „Portsysteme”

Abstract
In 18 patients with primary or secondary liver tumours, 38 digital subtraction angiographies (DSA) of totally implanted catheter systems for liver perfusion were performed during a period of 8 months. The systems had been used for an average of 6.9 months. In 22 out of 38 examinations secondary reactions of liver arteries were observed, in 7 the therapeutic regimen was changed after DSA. Patients with an extensive tumour involvement of the liver showed mural thromboses or obstructions of liver arteries relatively more often (4 of 7) than patients with smaller size tumours (2 of 11). In 7 cases the therapeutic regimen was changed after DSA. DSA of implanted liver catheters is a valuable, well tolerated, easily and rapidly performed method.
