    Journal: J Comput Assist Tomogr; 1983 Feb; 7(1):106-12. PubMed ID: 6826828.
    Abstract:
    Dynamic computed tomography (CT) and real-time/pulsed Doppler ultrasonography were performed in 13 patients following a distal end-to-side splenorenal shunt (Warren procedure). The results were correlated with angiography. The anastomotic site was demonstrated by CT in all patients. Coincident enhancement of the distal splenic vein and left renal vein as demonstrated by dynamic CT was an accurate predictor of shunt patency. Ultrasound studies were performed using a transsplenic coronal imaging approach. Although the proximal splenic vein and left renal vein could be identified, it was not possible to directly evaluate the anastomotic site in any patients. Dynamic CT evaluation of splenorenal shunts may be a useful technique for monitoring shunt patency during long term follow-up and for evaluating patients who later rebleed.
