Fosphenytoin Description. Fosphenytoin Sodium Injection, USP is a prodrug intended for parenteral administration; its active metabolite is phenytoin. 1.5 mg of Fosphenytoin sodium is equivalent to 1 mg phenytoin sodium, and is referred to as 1 mg phenytoin sodium equivalents (PE).
The blood vessels may form scar tissue, which can pull on the retina causing a retinal detachment. A fluorescein angiogram is used to evaluate the retinal blood flow. Laser treatment is performed on those patients who develop neovascularization.
At the same time, the scarring caused by liver failure results in increased pressure in the portal vein, the blood vessel that leads into the liver. That causes a fluid backup, forcing excess fluid from the blood vessels into the abdomen to accumulate as ascites, according to the Gale Encyclopedia of Medicine.
