GESTATIONAL HYPERTENSION AND PREECLAMPSIA IN SINGLETON AND TWIN PREGNANCIES AND ITS RELATIONSHIP WITH CHORIONCITY IN TWIN PREG NANCIES

Background: Gestational Hypertension is defined as blood pressure of ? 140/90mmHg in a women without a previous history of arterial hypertension after 20 weeks of pregnancy. Aims and objectives: 1) To know and compare the prevalence of gestational hypertension and pr eeclampsia in singleton versus twin pregnancies. 2) To know and compare the prevalance of gestational hypertension and preeclampsia in monochorionic and dichorionic twins. Methodology: Hundred singleton and hundred twin pregnant women at 15 - 16 weeks of ge stational age attending antenatally O.P.D in Lalla Ded Hospital Srinagar over a period of one year were studied. Proper history was taken and examination was done. Along with routine investigations blood pressure and urine for proteins was noted,which was repeated at every antenatal visit.The chorionicity of twins was determined by antenatal ultrasound at first visit. The registered patients were followed till 36 weeks and admitted thereafter or earlier if needed. Results: Our study depicted that gestation al hypertension and preeclampsia is more common among twins 13%versus 7% in singletons. Further based on chorionicity, gestational hypertension and preeclampsia was found more often in monochorionic twins 20% than in dichorionic twins 13%. Conclusion: Gest ational hypertension/ preeclampsia is more common in twins especially monochronic twins.
