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.
对6例肾细胞癌患者在使用GAW螺旋装置进行姑息性肾动脉栓塞术后进行了随访血管造影。得出以下结论：有可能实现肾动脉完全闭塞，同时血尿停止、肿瘤大小及病理血管范围缩小。然而，有必要将螺旋装置准确放置在要闭塞的血管中，并栓塞供应肿瘤的所有主要动脉。即使肾动脉已完全闭塞，肿瘤生长仍会导致不同程度的进展。为减少这种侧支循环，应在进行螺旋闭塞之前，用合适的物质栓塞肿瘤周边的血管。
