Thrombotic thrombocytopenic purpura (TTP) is an ultra-rare but life-threatening thrombotic disorder that can lead to significant morbidity and mortality if not diagnosed and treated promptly. The condition causes small blood clots in blood vessels throughout the body, disrupting normal blood flood and supply, and leading to bleeding underneath the skin (bruising), impaired coagulation, damage to the red blood cells (which carry oxygen through the body), and organ dysfunction and failure (from lack of blood supply). There are 2 types of TTP: congenital (cTTP) and immune-mediated (acquired) (iTTP).i
