how can you tell the difference between a real and a fake thrombus?
the genuine one has an attachment point where it attaches to the blood vessels. The fake thrombus formed post mortem and is jelly-like.
How is a broken femur and thrombocytopenia related?
When long bones break, fat embolisms can form (the bone marrow goes into the blood) and the fat embolisms attract the platelets and cause thrombocytopenia
