A ๐Ÿงต on chest Xray signs in pulmonary thromboembolism.
The ๐—™๐—น๐—ฒ๐—ถ๐˜€๐—ฐ๐—ต๐—ป๐—ฒ๐—ฟ ๐˜€๐—ถ๐—ด๐—ป is a prominent central artery that can be caused either by pulmonary hypertension or by distension of the vessel by a large pulmonary embolus seen on chest x ray.
๐—›๐—ฎ๐—บ๐—ฝ๐˜๐—ผ๐—ป ๐—ต๐˜‚๐—บ๐—ฝ refers to a dome-shaped, pleural-based opacification in the lung most commonly due to pulmonary embolism and lung infarction (it can also result from other causes of pulmonary infarction (e.g. vascular occlusion due to angioinvasive aspergillosis)
๐—ช๐—ฒ๐˜€๐˜๐—ฒ๐—ฟ๐—บ๐—ฎ๐—ฟ๐—ธ ๐˜€๐—ถ๐—ด๐—ป: Focal Oligaemia
The focal area of increased translucency due to oligaemia is caused by impaired vascularisation of the lung due to primary mechanical obstruction or reflex vasoconstriction.
The ๐—ž๐—ป๐˜‚๐—ฐ๐—ธ๐—น๐—ฒ ๐˜€๐—ถ๐—ด๐—ป refers to the abrupt tapering or cutoff of a pulmonary artery secondary to a pulmonary embolus (PE).
This is an important ancillary finding in pulmonary embolism, and often associated with the Fleischner sign of dilated central pulmonary arteries.
