Abstract:
In 37 patients with porto-caval shunts, the operation site was examined on 40 occasions by i.a. DSA (25 Warren shunts, four Linton shunts and eight Drapanas shunts). The problem of shunt persistence could be resolved on 39 occasions. Only once was it not possible to evaluate the shunt because of artifacts. Artifacts caused by breathing, peristalsis and low contrast in the portal-venous segment did not prove serious problems in evaluating shunt patency. Intra-arterial DSA provides a comprehensive demonstration of the portal venous vascular territory and permits evaluation of post-operative haemodynamics.
