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.

D015901 Angiography, Digital Subtraction A method of delineating blood vessels by subtracting a tissue background image from an image of tissue plus intravascular contrast material that attenuates the X-ray photons. The background image is determined from a digitized image taken a few moments before injection of the contrast material. The resulting angiogram is a high-contrast image of the vessel. This subtraction technique allows extraction of a high-intensity signal from the superimposed background information. The image is thus the result of the differential absorption of X-rays by different tissues. Digital Subtraction Angiography,Subtraction Angiography, Digital
