Deep vein thrombosis, or DTV, happens when a blood clot forms in a vein deep inside your body. DTV in pregnancy is a rare but serious complication during gestation that can lead to a pulmonary embolism, or PE. Fortunately, DVT and PE are both treatable and often preventable. Let’s take a look at what you should know about DVT to protect yourself and your baby during and after pregnancy.
Pregnancy makes a woman approximately five times more likely than other women to have DVT. Even with those statistics, it only occurs in about one out of every 1,000 pregnancies, making it fairly uncommon. The risk of complication increases during the six weeks after birth but drops back to normal after eight weeks.
When a woman is pregnant, her number of blood clotting proteins increases while the anti-clotting proteins decrease. This is most likely a body’s defense against hemorrhaging during childbirth. The uterus also presses more on veins as it expands, and blood flow in the legs reduces later in pregnancy. Combine all of that, and the risk begins to make more sense.
While not everyone experiences the signs of DVT in pregnancy, it is important to be aware of them just in case. Most commonly, a clot will form in the left leg first. Symptoms to look for are:
If the clot has dislodged from the leg and moved to the lungs, you will experience a different set of symptoms. Speak to your doctor immediately if you experience:
Deep vein Thrombosis is fairly uncommon, but some factors increase the risk of developing a clot. Risk factors include:
Normally, the body breaks down clots before they become an issue. During pregnancy, there is an elevated risk that instead the clot will grow and break off. The clot travels through the blood to the lungs. This causes a pulmonary embolism, one of the most common pregnancy-related deaths in first-world countries.
Blood clots can also form in the placenta, possibly resulting in miscarriage or stillbirth. This is most common with women who are already at higher risk for blood clots. Clots can also cause:
Treating DVT in pregnancy is mostly about prevention and management. Options like surgery should wait until well after the baby is born, for your safety and theirs. Be aware of DVT warning signs and let your doctor know if you have a history of clots.
