[DSA in the postoperative diagnosis of patients with kidney transplants]

Image quality and diagnostic significance of intravenous and intraarterial DSA following renal transplantation were assessed in 40 angiographic studies. In 27 of 40 DSA (67.5%) there were pathologic findings such as a renal artery stenosis, aneurysms or rejection within this selected group of patients. There were significant differences in image quality between intravenous and intraarterial DSA. The value of intravenous DSA is limited, particularly in patients with complex anastomosis, implanted polar arteries and kinking stenosis.
