    Abstract:
    AIMS: The efficacy of somatostatin in altering splanchnic hemodynamics in cirrhotic portal hypertension is still controversial. We aimed to establish the dynamic effect of somatostatin on portal pressure in cirrhotic patients and compared its effect with Partial Splenic Embolization (PSE). METHODS: Eighteen patients with cirrhotic portal hypertension were prospectively recruited. The wedged hepatic venous pressure (WHVP) and free hepatic venous pressure (FHVP) were repeatedly measured at baseline, 1-, 5-, 10- and 20-min after initiating somatostatin infusion. After somatostatin infusion cessation and washout, WHVP and FHVP were measured before and after PSE. The change in all the variables between time points was analyzed. RESULTS: Decreased hepatic venous pressure gradient (HVPG) 5-min after initiation of infusion was identified compared with baseline level (19.6%; p-value: .042), which was achieved through elevated FHVP (37.5%; p-value: 9.26e - 04). There was no significant decrease in WHVP at any time point during somatostatin infusion. The HVPG (17.4%; p-value: 1.27e - 04) and WHVP (10.4%; p-value: 3.00e - 03) post-PSE significantly decreased compared to the washout level. No significant distribution differences in the number of patients with HVPG decrease by a percentage relative to the baseline level were identified between the 5-min time point and post-PSE. CONCLUSION: Our study indicates that somatostatin administration does not decrease WHVP within 20 min at clinically recommended doses. While somatostatin did decrease HVPG, this effect was achieved through increased FHVP, providing a possible explanation for its unclear efficacy. In contrast, PSE decreases both the WHVP and the HVPG.
