embolism

Blood clots form in the veins and can break loose and travel with the circulation to the lungs, leading to pulmonary embolism.

The two-year-old, who was found under a pile of blankets with “traumatic injuries from head to toe” on 30 June 2023, officially died from a bone marrow embolism as a consequence of skeletal trauma.

That would cause an air embolism - a blockage caused by an air bubble in the blood circulation.

The cause of Isabella's death had been given as "bone marrow embolism caused by skeletal trauma", jurors were told.

A serious concern is that the injection can cause a blockage in a blood vessel that can in turn lead to a blood clot travelling to the lungs – what is known as a pulmonary embolism.
