Magnetic resonance venography

an infection of the fascia that progresses rapidly and destroys skin and cutaneous tissue, may develop but is very rare. With this type of infection, drainage is thin and copious, and the subcutaneous tissue bleeds easily

Necrotizing fasciitis

what may a coagulopathy lead to?

PPH and, in turn, PPH results in a loss of clotting factors, thus limiting the body's ability to stop the bleeding.
