Abstract
Thrombotic thrombocytopenic purpura (TTP) is a rare and serious condition caused by a deficiency in the enzyme ADAMTS-13, leading to abnormal clotting and potential organ damage. Pregnancy can trigger TTP due to physiological changes in coagulation, significantly increasing the risk when ADAMTS-13 levels are severely deficient. The enzyme ADAMTS-13 cleaves vWF multimers, but in TTP, its deficiency leads to abnormal platelet aggregation and microvascular thrombi formation, causing organ damage, hemolytic anemia, and thrombocytopenia. This results in impaired blood flow and significant end-organ perfusion issues. TTP symptoms range from asymptomatic to severe, often mimicking other pregnancy-related complications like HELLP syndrome and preeclampsia, making diagnosis challenging. Clinical signs include thrombocytopenia, hemolytic anemia, neurological deficits, fever, and renal dysfunction, with recurrent fetal loss and intrauterine growth restriction also common. Diagnosis relies on clinical evaluation and laboratory findings, while awaiting ADAMTS-13 activity results. Effective communication and prompt multidisciplinary collaboration are crucial in diagnosing and treating TTP. Nurses play a vital role in assessment, collaboration, and patient and family communication to address complex complications during pregnancy.
