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

The right bronchial tree consists of three segmental branches in the lung's upper lobe, two segmental branches in the middle lobe, and five segmental branches in the lower lobe.

In 2005, a pregnant 25-year-old woman coughed up a similar blood clot that was a copy of the bronchial tree, per the European Journal of Cardio-Thoracic Surgery.

While being treated in hospital, he started coughing up blood and mucus, which apparently increased the strain on his lungs, and doctors had started treating him with oxygen tanks.

The 36-year-old had been admitted to hospital with heart failure, but died during his first week of treatment.

He had considerable intervention, including an aortic-valve replacement, stenting of an aortic aneurysm and a permanent pacemaker had been implanted for complete heart block.

However, these medications also increase the risk of bleeding, including coughing up blood.

"Blood clots may develop, which can travel through your blood vessels and block the blood flow to other organs, including your lungs making breathing hard", according to the Impella website.

"We were astonished", Dr. Georg Wieselthaler, a heart and lung surgeon at the University of California, San Francisco (UCSF), who treated the patient, told the Atlantic.

To reduce clotting, doctors use a blood thinner called heparin.

After coughing up part of his lung, the patient was immediately intubated and doctors performed a bronchoscopy, which is a test that allows them to examine airways.

According to doctors, the clot was a near flawless cast of the man's right bronchial tree.

Sadly, a week after the man coughed up the clot, he died due to complications from heart failure despite being fitted out with the ventricular assistance device.

After this episode, he ceased coughing up blood, and his tubes were removed a couple days later.
