US Man Coughs Up Blood Clot ‘Cast’ of His Lung

A 36-year-old man was admitted to the intensive care unit with an acute exacerbation of chronic heart failure. His medical history included heart failure with an ejection fraction of 20% bioprosthetic aortic-valve replacement for bicuspid aortic stenosis

While people may cough out blood due to certain medical conditions, at times it can get even worse.

Doctors are bewildered as to how an extraordinarily shaped blood clot came out of a patient.

In other words, the man was rushed to hospital with chronic heart failure and to help his heart, doctors at the University of California - where the man was admitted - connected him to a machine created to maximise blood flow around the body.

A 36-year-old California man has passed away after suffering from chronic heart failure and coughing so severely that he coughed up a part of his lung.

He had been hooked up to a ventricular assist device - used to help circulate blood around the body - and administered anti-coagulation therapy (blood thinners).

Georg Wieselthaler, a transplant and pulmonary surgeon at UCSF, told the Atlantic his team was easily able to identify the origin of the clot, it was so detailed.

Doctors were surprised by the blood clot cast.

While that, in and of itself, is something astounding, the medical staff treating the unnamed man were astonished to find that, given his unique medical circumstances, the man had actually expectorated a perfectly intact cast of his right bronchial tree, one of the tubular networks that brings air to and from the lungs.

When Wieselthaler and his team delicately spread out the clot, they discovered "that the architecture of the airways had been retained so perfectly that they were able to identify it as the right bronchial tree based exclusively on the number of branches and their alignment". One week after extubation, he died from complications of heart failure (volume overload and poor cardiac output) despite placement of the ventricular assist device.

"It's a curiosity you can't imagine".

The 36-year-old patient was in intensive care.
