The Phase Gate Review methodology improves project effectiveness by reviewing all stages of the project from the initial selection process through the entire process of development to the final stages of closure.
Systemic hypertension, or high blood pressure, is associated with hypertensive vascular disease and is a problem that is widespread. The term systemic distinguishes the condition from a local high blood pressure as in pulmonary (lung) or portal hypertension (hepatic portal system).
Portal hypertension occurs when there is an obstruction of blood flow through the liver and pressure rises within the portal vein. This obstruction can be intrahepatic (intra=within +hepatic=liver), pre-hepatic (pre=before) or post- hepatic (post=after).
