    Abstract:
    Remarkable changes are seen on gross and microscopic examination of placenta of patients with sickle cell disorders, hence the present study was undertaken to find out the pathological changes seen in the placenta of sickle cell disorder patients, as compared to control and to study the effect of maternal sickling on the fetus. It includes total 73 cases, of which 10 were of control group and 63 were from patients with sickle cell disorders, which included 47 sickle cell trait (AS) and 16 sickle cell disease (SS) patients. In group II, 9 (14.28%) patients with SS pattern developed complications during pregnancy, in the form of vaso-occlusive and hemolytic crises. Pregnancy induced hypertension was seen in 4 (25%) out of 16 SS and 11 (23.40%) of the 47 AS patients. Urinary tract infection (UTI) was seen in 6 (37.5%) out of 16 SS and 8 (17.02%) out of 47 AS patients. Placentae in sickle cell disorders showed pathological changes in the form of infarction, calcification, sickled red blood cells and hemorrhage in intervillous spaces, increased syncytial knots, fibrinoid necrosis, stromal fibrosis, hyalinised villi and compensatory proliferation of trophoblastic cells.
