Ji. Bilbao et al., EMBOLIZATION OF NONVARICEAL PORTOSYSTEMIC COLLATERALS IN TRANSJUGULARINTRAHEPATIC PORTOSYSTEMIC SHUNTS, Cardiovascular and interventional radiology, 20(2), 1997, pp. 149-153
Percutaneous embolization of large portosystemic collaterals was perfo
rmed in three patients following placement of a transjugular intrahepa
tic portosystemic shunt in order to improve hepatopetal portal flow, I
mproved hepatic portal perfusion was achieved in these cases, thereby
theoretically reducing the risk of chronic hepatic encephalopathy.
