A 36-year-old man died after suffering from chronic heart failure and coughing so badly that he spat a bright red blood clot perfectly in the shape of passages of the respiratory tract of the bronchial tree of his right lung.
The unidentified patient was receiving treatment in the intensive care unit at the University of California, San Francisco Medical Center, according to a November 29 article in the New England Journal of Medicine.
During the week of his hospitalization, the cough of the man has progressed to produce blood and phlegm. During a rather extreme hack, he coughed "an intact cast of the right bronchial tree," says the article.
"The right bronchial tree consists of three segmental branches in the upper lobe, two segmental branches in the middle lobe and five segmental branches in the inferior lobe," wrote the authors of the journal, "The patient's trachea was subsequently intubated and flexible bronchoscopy revealed a small amount of blood in the basilar branches of the lower right lobe. "
The man was extubated two days after the accident and no longer suffered from blood.
He died a week later due to complications in heart failure, according to the newspaper.
