  • Title: Splanchnic hemodynamic factors in cirrhosis with refractory ascites.
    Author: Lebrec D, Kotelanski B, Cohn JN.
    Journal: J Lab Clin Med; 1979 Feb; 93(2):301-9. PubMed ID: 429841.
    Abstract:
    Splanchnic and systemic hemodynamic observations in eight patients with cirrhosis and refractory ascites were compared to those of 25 patients with cirrhosis and responsive ascites. The refractory ascitic group was characterized by less portasystemic shunting from both the superior mesenteric and splenic vascular beds, a lower cardiac output, a higher systemic vascular resistance, a wider arterial-hepatic venous oxygen difference, and a tendency for a lower HBF and higher postsinusoidal resistance. Portal pressures assessed from hepatic vein catheterization were similar in the two groups. The absence of a well-developed portasystemic collateral bed in patients with refractory ascites could in part be caused by the tense ascites but could also be an important factor in the mechanism of refractory ascites.
