Variceal bleeding is one of the most serious complications of portal hypertension. The driving force for the development of varices is an increase in portal pressure. As portal hypertension progresses, varices dilate until they finally rupture and bleed. This sequence of events might be prevented by achieving a sufficient decrease in portal pressure or by acting locally at the varices with endoscopic treatments. This article reviews the rationale for the management of portal hypertension and the current recommendations for the prevention and treatment of variceal bleeding.

UI MeSH Term Description Entries
D006975 Hypertension, Portal Abnormal increase of resistance to blood flow within the hepatic PORTAL SYSTEM, frequently seen in LIVER CIRRHOSIS and conditions with obstruction of the PORTAL VEIN. Cruveilhier-Baumgarten Disease,Cruveilhier-Baumgarten Syndrome,Cruveilhier Baumgarten Disease,Cruveilhier Baumgarten Syndrome,Disease, Cruveilhier-Baumgarten,Portal Hypertension,Portal Hypertensions,Syndrome, Cruveilhier-Baumgarten
D011379 Prognosis A prediction of the probable outcome of a disease based on a individual's condition and the usual course of the disease as seen in similar situations. Prognostic Factor,Prognostic Factors,Factor, Prognostic,Factors, Prognostic,Prognoses
D006471 Gastrointestinal Hemorrhage Bleeding in any segment of the GASTROINTESTINAL TRACT from ESOPHAGUS to RECTUM. Hematochezia,Hemorrhage, Gastrointestinal,Gastrointestinal Hemorrhages,Hematochezias
D006488 Hemostasis, Surgical Control of bleeding during or after surgery. Surgical Hemostasis,Hemostases, Surgical,Surgical Hemostases
D006490 Hemostatics Agents acting to arrest the flow of blood. Absorbable hemostatics arrest bleeding either by the formation of an artificial clot or by providing a mechanical matrix that facilitates clotting when applied directly to the bleeding surface. These agents function more at the capillary level and are not effective at stemming arterial or venous bleeding under any significant intravascular pressure. Antihemorrhagic,Hemostatic,Antihemorrhagics
D006801 Humans Members of the species Homo sapiens. Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D012307 Risk Factors An aspect of personal behavior or lifestyle, environmental exposure, inborn or inherited characteristic, which, based on epidemiological evidence, is known to be associated with a health-related condition considered important to prevent.

D053704 Capsule Endoscopy Non-invasive, endoscopic imaging by use of VIDEO CAPSULE ENDOSCOPES to perform examination of the gastrointestinal tract, especially the small bowel.

D018608 Ultrasonography, Doppler Ultrasonography applying the Doppler effect, with frequency-shifted ultrasound reflections produced by moving targets (usually red blood cells) in the bloodstream along the ultrasound axis in direct proportion to the velocity of movement of the targets, to determine both direction and velocity of blood flow.
