  3. Common hepatic artery - Wikipedia

    en.wikipedia.org/wiki/Common_hepatic_artery

    The common hepatic artery is a short blood vessel that supplies oxygenated blood to the liver, pylorus of the stomach, duodenum, pancreas, and gallbladder. [ citation needed ] It arises from the celiac artery [ 1 ] and has the following branches: [ 2 ]

  4. Portal hypertension - Wikipedia

    en.wikipedia.org/wiki/Portal_hypertension

    Portal hypertension is defined as increased portal venous pressure, with a hepatic venous pressure gradient greater than 5 mmHg. [3] [4] Normal portal pressure is 1–4 mmHg; clinically insignificant portal hypertension is present at portal pressures 5–9 mmHg; clinically significant portal hypertension is present at portal pressures greater than 10 mmHg. [5]

  5. Hepatic portal system - Wikipedia

    en.wikipedia.org/wiki/Hepatic_portal_system

    In human anatomy, the hepatic portal system or portal venous system is the system of veins comprising the portal vein and its tributaries. The other portal venous system in the body is the hypophyseal portal system .

  6. Arterial resistivity index - Wikipedia

    en.wikipedia.org/wiki/Arterial_resistivity_index

    Normal mean renal artery RI for an adult is 0.6 with 0.7 the upper limit of normal. In children, RI commonly exceeds 0.7 through 12 months of age and can remain above 0.7 through 4 years of age. [ 4 ]

  7. Hepatic veno-occlusive disease - Wikipedia

    en.wikipedia.org/wiki/Hepatic_veno-occlusive_disease

    Hepatic veno-occlusive disease (VOD) or veno-occlusive disease with immunodeficiency is a potentially life-threatening condition in which some of the small veins in the liver are obstructed. It is a complication of high-dose chemotherapy given before a bone marrow transplant or excessive exposure to hepatotoxic pyrrolizidine alkaloids .

  8. Abdominal ultrasonography - Wikipedia

    en.wikipedia.org/wiki/Abdominal_ultrasonography

    Abdominal ultrasound can be used to diagnose abnormalities in various internal organs, such as the kidneys, [1] liver, gallbladder, pancreas, spleen and abdominal aorta. If Doppler ultrasonography is added, the blood flow inside blood vessels can be evaluated as well (for example, to look for renal artery stenosis).

  9. Hepatic artery embolization - Wikipedia

    en.wikipedia.org/wiki/Hepatic_artery_embolization

    The several types of hepatic artery treatments are based on the observation that tumor cells get nearly all their nutrients from the hepatic artery, while the normal cells of the liver get about 70-80 percent of their nutrients and 50% their oxygen supply from the portal vein, and thus can survive with the hepatic artery effectively blocked. [2]
