| RVA | re-entrant ventricular arrhythmia; right ventricle activation; right vertebral artery |
| RVEF | right ventricular ejection fraction; right ventricular end-flow |
| RVF | renal vascular failure; Rift Valley fever; right ventricular failure; right visual field |

| venous segments of liver | Each of the four territories of the liver separately drained by the hepatic veins. Synonym: hepatic venous segments. (05 Mar 2000) |
|---|---|
| cavernous haemangioma of liver | <radiology> Ultrasound: increased echogenicity, CT: decreased density, enhances from periphery, becomes isodense, may enlarge during pregnancy, in kids: most common benign liver tumour, increased morbidity/mortality, classic triad: hepatomegaly, cut. Haemangiomas, congestive heart failure, with or without liver bruit, may rupture leading to haemoperitoneum, may regress spontaneously (as may haemangioendothelioma) (12 Dec 1998) |
| visceral surface of liver | The posteroinferior surface of the liver that faces adjacent abdominal organs; the porta hepatis and gallbladder are located on this surface. Synonym: facies visceralis hepatis. (05 Mar 2000) |
| central veins of liver | The terminal branches of the hepatic veins that lie centrally in the hepatic lobules and receive blood from the liver sinusoids. Synonym: venae centrales hepatis, Krukenberg's veins. (05 Mar 2000) |
| metastases to the liver | <oncology> The spread of cancerous tumours from a distant organ to the liver. Due to the livers tremendous blood and lymphatic supply it is a frequent site for metastatic cancer. Cancers which commonly metastasize to the liver include colon cancer, breast cancer, neuroblastoma, lung cancer and Hodgkin's disease. (27 Sep 1997) |
| chronic active liver disease | Any of several types of hepatitis persisting for more than six months, often progressing to cirrhosis. Synonym: chronic active liver disease. (05 Mar 2000) |
| microsomes, liver | In the hepatocyte, any of the vesicular fragments of endoplasmic reticulum formed after disruption and centrifugation of cells. (12 Dec 1998) |
| mitochondria, liver | Mitochondria in hepatocytes. As in all mitochondria, there are an outer membrane and an inner membrane, together creating two separate mitochondrial compartments: the internal matrix space and a much narrower intermembrane space. In the liver mitochondrion, an estimated 67% of the total mitochondrial proteins is located in the matrix. (12 Dec 1998) |
| wandering liver | A downward displacement of the liver. Synonym: wandering liver. Origin: hepato-+ G. Ptosis, a failing (05 Mar 2000) |
| cod liver oil | <chemical> The partially destearinated fixed oil obtained from fresh livers of gadus morrhua and other species of gadidae, the cod family. It is used as a source of vitamins a and d. In veterinary medicine, it is also used topically to promote wound healing and in abscesses, burns, and dermatoses. Chemical name: Cod-liver oil (12 Dec 1998) |
| pigmented liver | A liver that contains pigment, such as occurs in Dubin-Johnson syndrome, haemochromatosis, long-standing malaria. (05 Mar 2000) |
| cold liver lesion | <radiology> Size for detection = 1-2 cm (3-cm deep lesions), primary tumour (haemangioma hot by Tc-RBCs), metastasis, inflammatory lesion (e.g., amebic abscess), degenerative disease, trauma, congenital lesion (solitary cyst or polycystic disease) see: liver-spleen scan (12 Dec 1998) |
| waxy liver | Amyloid degeneration of the liver. Synonym: lardaceous liver. (05 Mar 2000) |
| complex liver mass in kids | <radiology> Epithelial, FNH (uncommon, F greater than M), hepatic adenoma (uncommon, F greater than M), hepatoma (increased aFP in 90%), hepatoblastoma (increased aFP, less than 2 years of age), mesenchymal, hamartoma, cavernous haemangioma, haemangioendothelioma, embryonal rhabdomyosarcoma (obstructs common bile duct; less than 5 years of age), undifferentiated sarcoma, teratoma, abscess / haematoma / complicated cyst (12 Dec 1998) |
| constitutional liver dysfunction | An inherited disorder that affects the way bilirubin in handled by the liver. Thought to be due to an inborn error of bilirubin metabolism. Symptoms include mild jaundice, weakness, fatigue, nausea and abdominal pain. (27 Sep 1997) |
