| deep vein thrombosis | Blood clotting in the veins of the inner thigh or leg. In air travel, DVT is the economy-class syndrome. Even in young, health travelers the long stretches immobilised in cramped seats in cabins with very low humidity set the stage for the formation of a thrombus (blood clot) in the lower leg. Blood clots can break off (as an embolism) and makes its way to the luhg where it has the potential of causing respiratory distress and respiratory failure. (12 Dec 1998) |

| portal circulation | Circulation of blood to the liver from the small intestine, the right half of the colon, and the spleen via the portal vein; sometimes specified as the hepatic portal circulation, more generally, any part of the systemic circulation in which blood draining from the capillary bed of one structure flows through a larger vessel(s) to supply the capillary bed of another structure before returning to the heart; e.g., the hypothalamohypophyseal portal system.
