Tailored angiographic approach to small hypovascular renal tumors.
The value of an appropriate oblique view renal arteriography which we call "tailored oblique," was illustrated in 2 cases. In the first case, a renal mass on the left side with anterior exophytic growth was found by computerized tomography (CT). In the second case, a tumor on the right side with posterior exophytic growth was detected by CT. Preoperative angiographies were performed. In both cases, the anteroposterior projections were not diagnostic. But in the "tailored oblique" projections both showed definite tumor vessels. Both tumors were resected and proved to be renal cell carcinomas. We believe "tailored oblique" projection provides additional confirmative information on the nature of the tumor.
