  • Title: [Follow-up angiography after palliative renal artery occlusion with the GAW-(Gianturco-Anderson-Wallace)-spiral (author's transl)].
    Author: Riedl P, Flamm J.
    Journal: Rofo; 1979 Apr; 130(4):398-403. PubMed ID: 86488.
    Abstract:
    Follow-up angiograms were carried out in six patients after palliative renal artery embolisation for hypernephromas using a GAW-spiral. The following conclusions were reached: it is possible to obtain complete occlusion of the renal artery with cessation of haematuria, reduction in tumour size and in the extent of the pathological vessels. It is necessary, however, to place the spiral accurately in the vessel to be occluded and to embolise all major arteries supplying the tumour. Even when the renal artery has been completely occluded, tumour growth results in the development of varying extent. In order to reduce this collateral circulation, vessels to the tumour periphery should be embolised with a suitable substance before spiral occlusion is carried out.
