This case involves a female patient with a history of coronary artery disease, as well as a number of different cardiovascular defects, for which she had undergone multiple surgeries and was on blood thinning medication. A routine chest x-ray had revealed the presence of a mass in the lower lobe of her lung, and her pulmonologist recommended that she undergo an endobronchial ultrasound in order to obtain a more definitive diagnosis. Leading up to the procedure, she was admitted for an anticoagulation bridge before the endobronchial ultrasound, where she was placed on a Heparin drip. During the procedure to biopsy the mass, it was noted that the patient’s airways filled with blood and she began to hemorrhage, causing her to bleed out despite the surgeon’s efforts to implement a laryngotracheal reconstruction. A subsequent autopsy revealed evidence of vein injury, possibly related to the biopsy procedure, however there was no definitive evidence tying the bleed to an acute traumatic event. Nevertheless, the decedent’s estate alleged that the patient’s death was caused by an error on the part of her treating physicians.
