Fleischner sign is a radiological sign that aids the diagnosis of pulmonary embolism. [1] The sign indicates the dilatation of the proximal pulmonary arteries due to pulmonary embolism. [2] It was named after Felix Fleischner, who first described it. [3] The Fleishner sign is seen both on X-ray and CT scan of chest/thorax.

Knuckle sign is a radiologic sign used for diagnosing pulmonary embolism. [1] [2] The presence of a blood clot in the branch of a pulmonary artery can resemble a knuckle in CT and X-ray images, which is why it is called knuckle sign. [3] It is frequently seen along with other signs of pulmonary embolism, such as the Fleischner sign and ...
Other symptoms are syncope and hemoptysis. [14] DVT is a common cause. Thus, symptoms including leg pain, redness, and swelling can be present. [15] The likelihood of pulmonary embolism can be evaluated through various criteria. The Wells score is often calculated. It gives points based on these symptoms and patient risk factors. [13] [14]
Venous thrombosis can lead to pulmonary embolism when the migrated embolus becomes lodged in the lung. In people with a "shunt" (a connection between the pulmonary and systemic circulation), either in the heart or in the lung, a venous clot can also end up in the arteries and cause arterial embolism.
Chang sign usually appears within 24 hours of the onset of chest pain due to pulmonary embolism, [2] and the maximal dilatation of the descending pulmonary artery often occurs in two to three days after the onset of pain. [3] Chang sign is absent in case of co-existing pneumonia or other conditions causing central opacities, where the ...
Arterial gas embolism is caused by gas in the lungs getting into the pulmonary venous circulation through injuries to the capillaries of the alveoli caused by lung overpressure injury. These bubbles are then circulated to the tissues via the systemic arterial circulation, and may cause blockages directly or indirectly by initiating clotting.
Trousseau described several cases in which recurrent thrombosis was the presenting feature of visceral cancer, and his confidence in the utility of this connection led him to say, "So great, in my opinion, is the semiotic value of phlegmasia in the cancerous cachexia, that I regard this phlegmasia as a sign of the cancerous diathesis as certain ...
