[Correlation between microangiography and histological findings in renal carcinomas (author's transl)].
Arterial, venous and simultaneous arterial and venous injections with radio-opaque dyes were carried out under manometric control on three renal cell carcinomas following nephrectomy. The micro-angiographic appearances were then correlated with the histological findings. The radiologically abnormal vessels correspond with sinusoids with thin, capillary-like walls containing localised areas of thickening in a collagen-rich stroma. Both micro-angiographically and histologically, the sinusoidal connections can be demonstrated between the edge of the tumour and normal tissue. Arterio-venous anastomoses were not found. The angio architecture and micro-angiographic pattern in renal cell carcinomas is described. The significance of these changes in the circulation is discussed and its significance in carrying out pharmaco-angiography and retrograde phlebography is pointed out.
