| idiopathic pulmonary hypertension | <chest medicine> A condition where there is increased blood pressure in the pulmonary arteries with otherwise normal heart and lungs. The cause is unknown, but there is diffuse narrowing of the pulmonary arteries resulting in increased arteriolar pressures. Secondary heart failure ensues without correction of this problem. There is an increased incidence of this disease in females between the ages of 20 and 40 years. Treatment may include a heart and lung transplant in select cases. (27 Sep 1997) |

| infralobar part of posterior branch of right pulmonary vein | <anatomy, vein> The vein draining the posterior segment of the right lung that emerges inferior to the superior lobe; tributary to the posterior branch of the right superior pulmonary vein. Synonym: pars infralobaris rami posterioris venae pulmonalis dextrae. (05 Mar 2000) |
| intersegmental part of pulmonary vein | A vein receiving blood from adjacent bronchopulmonary segments; it emerges from the inferior margin of a segment to become a tributary of a branch of a pulmonary vein. Synonym: infrasegmental part, intersegmental part of pulmonary vein, pars infrasegmentalis. (05 Mar 2000) |

| intralobar part of the right superior pulmonary vein | <anatomy, vein> The vein draining the apical and posterior segments of the right lung; tributary to the posterior branch of the right superior pulmonary vein. Synonym: pars intralobaris venae pulmonalis dextrae superioris. (05 Mar 2000) |
| obstructive pulmonary overinflation | Emphysema caused by obstruction of airways that has greater effect on expiration than inspiration; occurs reversibly with bronchospasm of asthma; localised process can be due to aspiration of a foreign body. (05 Mar 2000) |
| opening of pulmonary trunk | The opening of the pulmonary trunk from the right ventricle, guarded by the pulmonary valve. Synonym: ostium trunci pulmonalis, pulmonary orifice. (05 Mar 2000) |
