Green's autopsy reveals that she died from pulmonary thromboemboli -- blood clots that formed in her legs and eventually made their way into her lungs, according to Ellen Borakove, the medical examiner's spokeswoman. The clots came from deep vein thrombosis, which complicated Green's chronic paranoid schizophrenia.
Many people afflicted with deep vein thrombosis are unaware they have the condition, but symptoms including pain or swelling in the leg or shortness of breath.
Drugs that stop the clots from forming can help and can also prevent existing clots from growing larger. Doctors recommend that people with deep vein thrombosis avoid long periods of inactivity and frequently exercise their legs during long trips.
After the security videos were released, the New York City Health and Hospitals Corporation, which oversees the hospital, said it was "shocked and distressed by this situation. It is clear that some of our employees failed to act based on our compassionate standards of care."
