ABSTRACT

Introduction: There is no information in the literature about surgical outcome of the distal splenorenal shunt (Warren shunt) in those patients with anomalous flow in the left renal vein to the inferior vena cava. Objective: The purpose of this manuscript was to evaluate the incidence of thrombosis in the Warren shunt in those patients with anomalous flow in the left renal vein to the inferior vena cava. Methods: We performed a prospective, descriptive and longitudinal study in those patients who performed a surgical procedure to the treatment of hemorrhagic portal hypertension in a tertiary referral center in Mexico City during a one year period (2002-2003). Before the surgical procedure an arterial and venous angiographic study was done including celiac axis, superior mesenteric artery and splenic artery. The patients were scheduled in the outpatient office the first, third, sixth month and the year after the surgical procedure. We looked in them for gastrointestinal bleeding secondary to portal hypertension. In those patients with Warren shunt an angiographic study was done during the first month after the surgical procedure. Results: Twenty eight patients were included, 17 of them women (60.7%). Median patient age was 48 years old. In 20 patients a Warren shunt were done and in eigth patients a devascularization operation were done. The anomalous flow of the left renal vein was identified in nine patients (28.7%). In seven of them a Warren shunt were done and in two of them a devascularization operation were done. We didn’t find gastrointestinal bleeding or thrombosis of the Warren shunt in any of these patients. Conclusion: In those cases of patients with anomalous flow in the left renal vein a Warren shunt can be performed. In this study we didn’t find thrombosis of the shunt or gastrointestinal bleeding. In this way a surgical decompression of the portal system can be done preventing bleeding episodes.
