Shunt an.d Sugiura Procedure in Patients with Cirrhosis

Systemic and splanchnic hemodynamics were studied before and six months after a portal systemic shunt (n 6) or a Sugiura procedure (n 9) in 15 patients with cirrhosis and a past history ofvariceal bleeding. Hepatic blood flow was estimated by hepatic extraction and clearance of continuous indocyanine green infusion. Azygos blood flow was measured with a continuous thermodilution catheter. After portocaval shunt, the cardiac index increased significantly from 4.0+1.4 to 5.4+0.8 l/min m2 (p < 0.05), the hepatic venous pressure gradient and hepatic blood flow were significantly decreased from 21+3 to 13+5mm Hg (p < 0.05) and from 1.20+0.35 to 0.37+0.16 l/min (p < 0.05) respectively. The decrease in azygos blood flow was not significant (0.51+0.31 vs 0.25+0.33 l/min; p 0.1). After Sugiura procedure, there was no significant change in cardiac index, hepatic venous pressure gradient, hepatic blood flow or azygos blood flow. This is the first study to show the long-term maintenance ofsplanchnic and systemic hemodynamics in patients with cirrhosis after Sugiura procedure. The absence of long-term hemodynamic alterations could explain the absence ofencephalopathy after this procedure.
