Experimental reduction of portal hypertension by mechanical increase of liver portal flow

Studies on the isolated perfused rat liver demonstrated that an increase in portal pressure is associated with an increase in the portal blood flow in normal and in cirrhotic livers. In two pigs with portal hypertension mesenteric portal pressure was lowered by mechanically increasing the liver portal blood flow by means of a balloon pump around the portal vein.

[Pseudo-Kaposi's syndrome of the left lower extremity. The Stewart-Bluefarb syndrome]

The authors relate one case of Stewart-Bluefarb syndrome in a 16 year old patient, showing cutaneous lesions with features of Kaposi angiosarcoma. Though there are no signs of direct arteriographic of arteriovenous communications (CAV). The other exams accomplished allow us to maintain CAV as an etiopathogenic hypothesis.
