Digital subtraction angiography for renal donor evaluation.
A consecutive series of 52 living related renal donors were evaluated preoperatively by angiography. The preoperative angiographic interpretation was compared with the anatomy found at donor nephrectomy. Standard selective renal arteriography was found to be 100 per cent accurate in defining single (25) or multiple (1) renal arteries. Digital subtraction angiography (DSA) alone performed with an intra-arterial injection of contrast material was found to be 82 per cent accurate in determining the number of renal arteries. In five kidneys with multiple renal arteries, only two had the correct number of vessels identified. The errors are inherent in the DSA technology. DSA at the present time is not accurate enough to replace the standard arteriogram in the evaluation of the donor nephrectomy patient.
