| 영문 | renal hypertension | 한글 | 콩팥성고혈압 |
|---|---|---|---|
| 설명 | 콩팥실질의 병변으로 인해 야기된 고혈압. 콩팥의 대표적 기능은 노폐물 및 수분의 배설이다. 그런데 이러한 콩팥기능에 이상이 생겼을 경우 체내에 과잉수분의 축적이 발생하게 된다. 이와같은 과잉수분의 축적은 혈관내 정수압을 상승시켜 고혈압을 유발하게 된다. 치료는 원인 콩팥병의 교정이며 이유를 모르는 원발고혈압과 달리 콩팥성고혈압의 경우에는 원인 콩팥병이 교정되면 고혈압도 사라지게 된다. |

| 영문 | renal cell carcinoma | 한글 | 콩팥세포암종 |
|---|---|---|---|
| 설명 | 콩팥에 생긴 원시콩팥조직에서 발생한 암. 주로 원시세뇨관조직에서 발생한다. 대표적인 세포조직형은 염색시 세포질이 맑게 비어보이는 맑은세포암종이다. 치료는 수술과 항암화학요법이며 아주 드물지만 저절로 낫는 경우도 있는 것으로 보고되어 있다. |

| 영문 | renal transplantation | 한글 | 콩팥이식 |
|---|---|---|---|
| 설명 | 콩팥병을 가지고 있으나 치료가 불가능한 만성콩팥기능상실 등의 질병을 가진 환자의 신장을 떼어내고 환자와 항원성이 유사한 사람의 콩팥을 이식해주는 것. 이 때 서로간의 항원성의 유사점이 많아야 거부반응이 일어나지 않는다. 그리고 일단 콩팥이식을 받은 사람은 오랜기간 동안 면역억제제를 투여하여 거부반응을 줄여야 한다. 대개 이식된 콩팥은 엉덩뼈오목에 위치하게 된다. |

| portal cirrhosis | Synonym: Laennec's cirrhosis. (05 Mar 2000) |
|---|---|
| portal fissure | A transverse fissure on the visceral surface of the liver between the caudate and quadrate lobes, lodging the portal vein, hepatic artery, hepatic nerve plexus, hepatic ducts, and lymphatic vessels. Synonym: caudal transverse fissure, portal fissure. (05 Mar 2000) |
| portal hypertension | Any increase in the portal vein (in the liver) pressure due to anatomic or functional obstruction (for example alcoholic cirrhosis) to blood flow in the portal venous system. Indicators of portal hypertension are: oesophageal varices, haemorrhoids, enlarged veins on the anterior abdominal wall (caput Medusae) and ascites (fluid within the abdominal cavity). (27 Sep 1997) |
| portal hypertension: classification | <radiology> Presinusoidal, extrahepatic: portal vein obstruction (extrinsic compression, phlebitis, OC, coagulopathy, tumour invasion, pancreatitis, neonatal omphalitis), dynamic: traumatic/neoplastic arterioportal fistula, segmental portal hypertension: splenic/superior mesenteric vein occlusion, intrahepatic (obstruction of portal venules): congenital hepatic fibrosis, primary biliary cirrhosis, sarcoid, myelofibrosis, schistosomiasis, idiopathic noncirrhotic fibrosis, Wilson disease, reticuloendotheliosis, Felty syndrome, chronic malaria, toxic fibrosis (arsenic, copper, PVC vapors) sinusoidal, cirrhosis, sclerosing cholangitis postsinusoidal, Budd-Chiari syndrome, constrictive pericarditis, congestive heart failure (12 Dec 1998) |
| portal hypophysial circulation | A capillary network that carries hypophyseotropic hormones from the hypothalamus, where they are secreted into blood, to their sites of action in the anterior hypophysis. See: portal circulation, hypophysis, hypothalamus. Synonym: hypophyseoportal system, hypophysial portal circulation, hypophysial portal system, hypophysioportal system, hypothalamohypophysial portal circulation, hypothalamohypophysial portal system. (05 Mar 2000) |
| portal lobule of liver | A conceptual unit of the liver, emphasizing its exocrine function in bile secretion, which comprises a roughly triangular shaped cross-sectional area with a portal canal at its centre and three or more venae centrales hepatis at its periphery. (05 Mar 2000) |
| portal pressure | The venous pressure measured in the portal vein. (12 Dec 1998) |
| portal pyaemia | Suppurative pylephlebitis. (05 Mar 2000) |
| portal system | A system of vessels in which blood, after passing through one capillary bed, is conveyed through a second set of capillaries before it returns to the systemic circulation. It pertains especially to the hepatic portal system. (12 Dec 1998) |
| portal-systemic anastomoses | Naturally-occurring venous communications between tributaries of the portal venous system and tributaries of the systemic venous system. The major portal-systemic anastomoses include: 1) oesophageal branches of left gastric vein with oesophageal veins, 2) superior rectal vein with middle and inferior rectal veins, 3) paraumbilical veins with subcutaneous veins of anterior abdominal wall, 4) retroperitoneal veins with venous branches of veins of the colon and bare area of the liver, and 5) a patent ductus venosus connecting left branch of portal vein to inferior vena cava (rare). These anastomoses are important clinically, providing collateral circulation during portal obstruction or hypertension, at which time they may become varicose. See: caput medusae, oesophageal varices, haemorrhoids. Surgically-created communications between the portal vein and the inferior vena cava or their tributaries, to relieve portal hypertension. Synonym: portacaval anastomoses. (05 Mar 2000) |
| portal-systemic encephalopathy | An encephalopathy associated with cirrhosis of the liver, attributed to the passage of toxic nitrogenous substances from the portal to the systemic circulation; cerebral manifestations may include coma. Synonym: hepatic encephalopathy. (05 Mar 2000) |
| portal triad | Branches of the portal vein, hepatic artery, and the biliary ducts bound together in the perivascular fibrous capsule or portal tract as they ramify within the substance of the liver. Synonym: hepatic triad, triad. (05 Mar 2000) |
| posterior intestinal portal | In young embryos, the communications from the midgut to the hindgut. (05 Mar 2000) |
| hepatic portal system | A venous portal system in which the portal vein receives blood via its tributaries from the capillaries of most of the abdominal viscera and drains it into the hepatic sinusoids. (05 Mar 2000) |
| hypertension, portal | Abnormally increased pressure in the portal venous system; frequently seen in cirrhosis of the liver and in other conditions which cause obstruction of the portal vein. (12 Dec 1998) |
