Coughing of the blood is an alarming symptom, but this is not particularly rare. Even so, a man in California shocked his doctors when he coughed at unusual blood clots: in the shape of his lung.
The 36-year-old male was being treated for a serious heart condition, according to a new report on the case in the New England Journal of Medicine on November 29th. She had chronic heart failure, which means that the heart muscle can't pump enough blood to meet the normal demands of the body.
His condition was so severe that the doctors put him on a machine called a ventricular assist device to help his heart pump. Since these machines could also increase the risk of blood clots, a less bloody drug was prescribed.
However, these drugs also increase the risk of bleeding including blood coughing. As a matter of fact, the report had a few episodes of cough, in which the patient took out small amounts of blood. But then, during the "extreme coughing episode", the patient spat a "solid cast" of the right bronchial tree. In other words, it was a mold (cast) made of blood coagulated blood in the form of lung branched airway passages known as bronchus.
"We were surprised," said Dr. San Francisco (UCSF) from California, a heart and lung surgeon. Georg Wieselthaler explained to the Atlantic who treated the patient. "A wonder that you cannot imagine – So, this is very, very rare."
Patients are less likely to cough bronchial eler coughs ür from other substances such as lymph or mucus. However, the Atlantic reports that blood is less sticky and more rigid than other substances, ie it is less likely to keep a cast made of blood together when it coughs.
Wieselthaler states that the levels of a protein called fibrinogen, which helps the blood clots of the patient, in this case increase; and higher levels of fibrinogen could help keep man's large clots intact when they coughed.
Although he had no more blood coughing attacks, he unfortunately died of heart failure complications a week later.
Wieselthaler's colleague, UCSF's clinical friend, Gavitt Woodard told the Atlantic that one reason they decided to publish the image was to show görünt the beautiful anatomy of the human body Gav.
