Definition & Terms
A quick guide to key concepts to support navigation and understanding.
The Index and Terms section is designed to support navigation and reinforce understanding of key concepts throughout this module. The index provides a structured overview of topics, allowing users to quickly locate specific sections and revisit important content. The terms component highlights essential terminology related to Budd-Chiari syndrome, offering clear and concise definitions to aid comprehension. Together, these tools enhance accessibility, promote efficient learning, and ensure that foundational concepts can be easily reviewed as users progress through the module.
Balloon catheter: a thin tube with an inflatable balloon used to widen narrowed or blocked blood vessels
Centrilobular regions: the central areas of liver lobules that are most vulnerable to low oxygen and injury
Collateral circulation: alternative blood vessels that form to bypass a blockage
Collateral vessels: alternative blood vessels that form to bypass a blockage and maintain blood flow
Cytopenias: a reduction in the number of blood cells (e.g., red cells, white cells, or platelets)
Effective blood volume: the amount of blood that actually reaches and perfuses organs
Fibrinolysis: the process of breaking down fibrin (the main component of blood clots)
Fibrinolytic system: the body’s system that breaks down blood clots
Focal or short-segment obstruction: a localized blockage affecting a small portion of the liver’s outflow veins
Hematologic: related to the blood and how it is made, functions, and circulates in the body
Hepatocellular injury: damage to liver cells (hepatocytes)
Hepatocyte: a liver cell responsible for metabolism, detoxification, and protein production
Hypercoagulable state: a condition where the blood clots more easily than normal, increasing the risk of forming unwanted clots
Liver sinusoids: tiny, specialized blood channels inside the liver where blood flows slowly so the liver can filter it, remove toxins, and process nutrients
Perfusion: the flow of blood through tissues and organs, delivering oxygen and nutrients to cells
Plasminogen: an inactive protein that is converted into plasmin to dissolve clots
Recanalization: the reopening of a blocked blood vessel to restore blood flow
Stent: a small mesh tube inserted into a blood vessel to keep it open and maintain blood flow
Thrombosis: the formation of a blood clot inside a blood vessel, which can block or slow down normal blood flow
Vasculature: the network of blood vessels in the body, including arteries, veins, and capillaries, that carry blood to and from different tissues and organs
Variceal bleeding: bleeding from enlarged veins caused by high pressure, usually in the esophagus or stomach
Vessel patency: the state of a blood vessel being open and allowing normal blood flow
