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).
This is called portal hypertension. Less common causes of portal hypertension and esophageal varices include blood clots in the veins leading to and from the liver and schistosomiasis. Schistosomiasis is a parasitic infection that can clog up the liver, causing pressure to back up in the portal vein.
