  Abstract 


Introduction: Venous thromboembolism (VTE) is the leading cause of maternal mortality in the Western population. Studies have shown that the incidence of VTE may not be different in the Indian population. The aim of this study is to understand the prevalence of VTE risk factors in Indian pregnant women. Materials and Methods: Two hundred antenatal and postnatal women attending the Gynecology outpatient clinics between April 1, 2019 and July 31, 2019, were sampled using pragmatic approach. Green-top guidelines (Royal College of Obstetricians and Gynecologists) were used to identify the risk factors. Descriptive statistics were used to analyze and present the data. Results: The mean age of the women was 26.18 (range 20–41). In the sampled population, 39 (19.5%), 41 (20.5%), and 110 (55%) women were in the first, second, and third trimester, respectively. Ten women (5.3%) were in the postpartum period. Out of 200 pregnant women, 2 (1%) had the previous history of VTE putting them in the high-risk group and 40 (20%) had one or more intermediate risk factors (immobility, OHSS, medical comorbidities, and surgical procedures). Eleven women (5.5%) had three or more risk factors and 40 women (20%) had two or more of the low-risk factors. Overall, 80 of 200 pregnant women (40%) had VTE risk factors that would require DVT prophylaxis during and/or postpartum period. Conclusion: The study highlights that a significant proportion of pregnant women in India have VTE risk factors. Routine VTE risk assessment and thromboprophylaxis could identify the women at risk and reduce the incidence of VTE in pregnant women.

  Introduction Top


Venous thromboembolism (VTE) is one of the most common causes of maternal mortality in the Western population. Although relatively low, the incidence of VTE in pregnant women in Eastern countries is still significant enough that it leads to major complications for the mother and the fetus. VTE in pregnancy occurs when women with inherited or acquired risk factors are exposed to predisposing factors. Identifying these risk factors in at-risk individuals and using prophylactic anticoagulation can prevent VTE in pregnancy. There are limited data on the prevalence of VTE risk factors in Indian pregnant women and their influence on VTE.

Aim

The aim of this study is to understand the prevalence of VTE risk factors in Indian pregnant women.


  Materials and Methods Top


This was a prospective pilot study including 200 antenatal and postnatal women attending the gynecology outpatient clinics in our institution between April 1, 2019 and July 31, 2019. The women were sampled using a pragmatic approach. The risk factors in each woman were assessed using the Royal College of Obstetrics and Gynaecology Green-top Guidelines. The data including the demographics were collected using an online form and converted to excel sheet for analysis. Statistical analysis was performed using Microsoft Excel version 2016.


  Results Top


The mean age of 200 pregnant women that were sampled in the given period (between the ages of 20 and 41) was 26.18 years. Of the 200, 39 women were in the first trimester (19.5%), 41 women were in the second trimester (20.5%) and 110 women were in the third trimester of pregnancy (55%). Ten women were in the postpartum period (5%). Hence, most women were in the third trimester of pregnancy. In the sample population, 2 women had a history of VTE, so they have a high risk of developing VTE during their current or consequent pregnancies.

Forty women (20% of the population) had one or more intermediate risk factors (immobility, OHSS, medical comorbidities, and surgical procedures). Forty women (20%) had one or more low-risk factor.

Eleven women (5.5%) had three or more various risk factors. Overall, approximately 80 women (40% of the population) had significant risk factors for the development of VTE during pregnancy and postpartum period and may require therapy.


  Discussion Top


Identifying at-risk people is key for VTE prevention. The results of our study show that 40% of Indian pregnant women have two or more risk factors that would require VTE thromboprophylaxis.


  Conclusion Top


The study highlights that a significant proportion of pregnant women in India have VTE risk factors. Routine VTE risk assessment and thromboprophylaxis could identify the women at risk and reduce the incidence of VTE in pregnant women.
