Man Dies After Coughing Up Lung's Bronchial Tree

Man Dies After Coughing Up Lung's Bronchial Tree

His condition was so severe that doctors put him on a machine called a ventricular assist device, which helps the heart pump blood.

The right bronchial tree consists of three segmental branches in the upper lobe (blue arrows), two segmental branches in the middle lobe (white arrows), and five segmental branches in the lower lobe (black arrows).

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.

"We were astonished", pulmonary surgeon Georg Wieselthaler told The Atlantic of the clot. The patient was already dying from heart failure.

Human lungs are too large to fit through the trachea, so it is not possible to cough up an entire lung.

The doctors treating the patient were "astonished" after they unfurled the clot to find it had retained the shape of the lung pathway from which it came. According to the manufacturer's website, it is a treatment designed for "no-option patients".




And, during a rather extreme hack, he coughed up "an intact cast of the right bronchial tree".

Wieselthaler told the publication that it was the man's blood medication that made the clot rubbery and able to survive the trip out his airway instead of breaking up, since blood clots are typically hard plugs of 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.

He also had to be supplied with oxygen due to breathing problems. Indeed, the patient had several coughing episodes in which he expelled small amounts of blood, according to the report.

It came from a 36-year-old man with end-stage heart failure who spat out the medical anomaly in one piece during a coughing fit in hospital.
