Abstract: The risk of developing dangerous blood clots, a condition called venous thromboembolism (VTE), increases dramatically during pregnancy. This risk is 4-5 times higher than for non-pregnant women and can occur throughout pregnancy, with some studies suggesting its more frequent during the first half. VTE includes deep vein thrombosis (DVT) and pulmonary embolism (PE), both of which can have serious complications like pulmonary hypertension, post-thrombotic syndrome, and venous insufficiency. Doctors utilize various diagnostic tools – including compression duplex ultrasonography, echo, ventilation-perfusion scans, and CT scans – for accurate diagnosis. Prompt treatment is crucial for the health of mother and baby. This article will thoroughly review existing research on thromboembolic diseases during pregnancy, providing a comprehensive understanding of this important issue.
