    Abstract:
    The aim of this study is to investigate the role of prostaglandins (PGI2 and TXA2) in relation with the hemodynamic alterations occuring after graft reperfusion in patients undergoing OLT. A total of 40 patients with liver cirrhosis were studied. Systemic 6-keto-PGF1 alpha and TXB2, stable metabolites of PGI2 and TXA2 respectively, were determined at the radial artery, at four different surgical stages: basal, hepatectomy, anhepatic, and 10 minutes after graft reperfusion. Overall results showed that 6-keto-PGF1 alpha levels were significantly elevated during hepatectomy (1143 +/- 204) when compared to values in the basal stage (p = 0.007). During hepatectomy, 6-keto-PGF1 alpha levels did not correlate to systemic vascular resistance index (SVRI), neither with the cardiac index (IC) nor with the medial arterial pressure (MAP) in the same stage. During the anhepatic stage, only IRVS was inversely correlated with 6-keto-PGF1 alpha levels (p = 0.004): there was no relation with MAP and CI. During reperfusion no correlations were observed between 6-keto-PGF1 alpha levels and MAP, CI or SVRI. We conclude that systemic PGI2 levels are very high in cirrhotic patients undergoing OLT. The absence of correlation between the magnitude of changes in hemodynamic parameters and 6-keto-PGF1 alpha levels during reperfusion of the new liver suggests that other factors must play a role in these hemodynamic changes.
