Summary
Thrombotic thrombocytopenia purpura (TTP) in pregnancy is rare. Splenectomy is the only treatment with a statistically significant survival improvement, with 60% of infants surviving when delivered at or beyond 33 weeks gestation.
Area of Science:
- Obstetrics and Gynecology
- Hematology
Background:
- Thrombotic thrombocytopenia purpura (TTP) is a rare but serious condition during pregnancy.
- Diagnosis typically relies on a pentad of symptoms: anemia, thrombocytopenia, renal disease, neurologic abnormalities, and fever.
Purpose of the Study:
- To report the twentieth case of TTP in pregnancy, highlighting a unique delivery via cesarean section.
- To review the diagnostic criteria and treatment outcomes for TTP in pregnancy.
Main Methods:
- Case report of a pregnant patient with TTP.
- Review of diagnostic methods including peripheral smear for microangiopathic hemolysis.
- Analysis of treatment options and survival rates.
Main Results:
- This case represents the third survivor of TTP in pregnancy and the first delivered by cesarean section.
- Splenectomy is identified as the sole treatment with a statistically significant improvement in survival rates.
- A survival rate of 60% was observed for infants born at or beyond 33 weeks' gestation.
Conclusions:
- TTP in pregnancy presents significant challenges but survival is possible with appropriate management.
- Splenectomy offers the best survival outcome for TTP in pregnancy.
- Early delivery after 33 weeks' gestation, particularly via cesarean section in this case, can contribute to infant survival.
