Thromboembolism

Area of Science:

• Obstetrics and Gynecology
• Hematology
• Public Health

Background:

• Venous thromboembolism (VTE) presents a significant cause of direct maternal mortality in developed countries, though a smaller percentage in developing nations.
• Pregnancy inherently elevates VTE risk due to physiological changes like venous stasis and altered blood coagulability.
• Clinical diagnosis of VTE in pregnancy is often unreliable, necessitating objective testing for accurate identification.

Purpose of the Study:

• To highlight the importance of VTE awareness and objective testing in pregnant women.
• To discuss the safe and effective management of VTE during pregnancy.
• To advocate for universal risk assessment and thromboprophylaxis strategies in pregnant individuals.

Main Methods:

• Diagnostic methods include compression or duplex ultrasonography for deep venous thrombosis and ventilation/perfusion scans for pulmonary embolism.
• Low molecular weight heparins are identified as safe and effective treatments and prophylactic agents.
• Risk assessment protocols are recommended for all women, ideally before or in early pregnancy.

Main Results:

• Risk assessment identifies factors such as obesity and a history of thromboembolism, enabling targeted thromboprophylaxis.
• Established guidelines for thromboprophylaxis have successfully reduced maternal deaths post-cesarean section.
• Development of comprehensive guidelines for all pregnant women is underway.

Conclusions:

• Early risk assessment and appropriate thromboprophylaxis are vital for mitigating maternal VTE risks.
• Objective diagnostic tools and safe pharmacological interventions are key to managing VTE in pregnancy.
• Standardized guidelines are essential for improving maternal outcomes related to VTE.
