BACKGROUND Phase-contrast MRI with metric-optimized gating is a promising new technique for studying the distribution of the fetal circulation. However, mean and reference ranges for blood flow measurements made in the major fetal vessels using this technique are yet to be established. METHODS AND RESULTS We measured flow in the major vessels of the fetal circulation in 40 late-gestation norm...

BehçetDisease (BD) is a systemic vasculitis characterized by recurrent oral and genital ulcers and uveitis, arthritis, and involvement of the gastrointestinal tract, central nervous system and blood vessels. The aneurysms of the pulmonary arteries, with or without thrombosis, are typical manifestation of BD. We report a case with BD, pulmonary arterial aneurysms(PAA) and in situ thrombosis. We ...

Anatomic In this paper a common (single) ventricle is defined as a ventricular chamber that receives the input of blood from both atrioventricular valves either separately or as a common atrioventricular valve" 2 (fig. 1). This common ventricular chamber may or may not communicate with a secondary, smaller outflow chamber. The two great vessels (aorta and pulmonary artery) may arise from the co...

Pulmonary arterial hypertension (PAH) is a progressive disease of the lung vasculature that involves the loss of endothelial function together with inappropriate smooth muscle cell growth, inflammation, and fibrosis. These changes underlie a progressive remodeling of blood vessels that alters flow and increases pulmonary blood pressure. Elevated pressures in the pulmonary artery imparts a chron...

CHEST, 74: 6, DECEMBER, 1978 pulmonary capillary wedge pressure to normal by increasing extramural pressure. So for us, therapy with IPPV and PEEP usually influences the pulmonary capillary wedge pressure, especially when the central blood volume varies from normal; thus, the interest and limits of the “weaning test” are clearly defined. In some cases, therapy with artificial ventilation does n...

although dental foci can be sources of bacteremia and bacterial endocarditis, hematogenous spread of infection presented with septic pulmonary embolism apparently is rare. the occurrence of septic pulmonary embolism in patients with periodontal disease without suppurative thrombophlebitis of the great vessels of the neck is well documented but to our knowledge, there is no report on septic pulm...

THE POSSIBLE relationship between pulmonary vascular pathological changes and an increased pulmonary blood flow and pulmonary-arterial blood pressure has been the subject of investigation for many years. Muller et al. and Ferguson et al. have demonstrated the development of vascular changes in the lungs following the surgical production of aortopulmonary shunts. The physiological changes associ...

Acute lung injury and acute respiratory distress syndrome (ARDS) arise from a wide variety of causes, but the common clinical manifestations are refractory hypoxaemia and increased pulmonary vascular resistance. A major pathological feature of acute lung injury and ARDS is damage to the pulmonary vascular endothelium, secondary to the activation and adhesion of platelets, neutrophils and monocy...
