[Intra-arterial digital angiography study of hemodialysis shunts].

The diagnostic possibilities of intraarterial DSA are demonstrated by means of 76 investigated haemodialysis shunts. No complications were seen. In 85% of the cases venous stenoses or occlusions were proved. 18% of these were localised in the proximal part of the draining veins. For this reason, investigation of the venous inflow into the V. cava superior is recommended in every case.
