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).
âPortal hypertension develops when there is resistance to portal blood flow and is aggravated by increased portal collateral blood flow. The resistance most often occurs within the liver (as is the case in cirrhosis), but it can also be prehepatic (eg, portal vein thrombosis) or posthepatic (eg, Budd-Chiari syndrome).
