Additionally, damage to intimal endothelium as well as intimal hyperplasia and fibrosis can be detected. Physiological agonists such as bradykinin and acetylcholine as well as mechanical stress derived from pulmonary blood flow can activate endothelial cells. Strittig ist bisher die Herkunft des steigenden zytosolischen Calciums. In the diagnosis of lung disease, assessing the pattern, location, and regional distribution of involvement is the domain of radiology. Das rechte Herz besitzt bei diesem Phänomen nicht mehr ausreichend Pumpleistung, um genügend Blut in den zurückzubefördern. This highlights the importance of early diagnosis as well as better preventive and management strategies. In addition, international review papers and original articles on smaller studies from the past 10 years were included for cases where the guidelines were not sufficiently up to date or detailed from the diagnostic radiology viewpoint.

This review discusses basic physiology, clinical concepts, and treatment options for pulmonary hypertension and the related right ventricular heart failure focusing on secondary pulmonary hypertension in patients during anesthetic procedures. Because the of the are more permeable to liquids than those of the alveolar cells, in the case of , fluid can leak into the and lead to. Together, they form a gas exchange surface area which is between 80 and 120 m2. Die Kombination von Ventilations- und Perfusionsszintigrafie ist in dieser Abfolge die Regel. Ohno Y, Koyama H, Nogami M, et al. The consistently close correlation between stimulation and catecholamine release suggests that the basic processes underlying the regulation of transmitter release from type I cells must be central in understanding the transduction process, although there remains some debate about the specific role and identity of the transmitter s involved. Ann Intern Med 1989; 111: 232—7.

Under conditions of chronic hypoxia generalised vasoconstriction of the pulmonary vasculature in concert with hypoxia-induced vascular remodelling leads to pulmonary hypertension. It is an independent predictor of mortality. In the projection image, in which all anatomical structures located in the path of the X-rays are superimposed on each other, about 70% of the lung volume can be freely seen in at least one projection. This investigation should be carried out first without contrast administration, using contrast-rich fast imaging sequences, to show a central pulmonary embolism within a few seconds. The chest radiograph can display an enlarged main pulmonary artery and enlarged hilar vessels, whereas the electrocardiogram shows a right axis deviation suggesting right ventricular hypertrophy.
