Questions and answers about pregnancy and VTE

After two miscarriages I was diagnosed with antiphospholipid syndrome. When I got pregnant again I was treated with heparin and adiro. However, I still had another miscarriage. I have a healthy son and both pregnancy and delivery were perfect, before the three miscarriages. Do I need another treatment?

Antiphospholipid syndrome is an immunological disease that is associated to a higher risk of thrombosis, and also of spontaneous miscarriages. Heparin and aspirin administration during pregnancy is associated to a lower number of miscarriages, but it doesn’t necessary avoid them. If you had a normal pregnancy and delivery before, most likely your antiphospholipid syndrome appeared later on. Whether you need another treatment or not, is something that your doctor will tell you. It depends on whether you become pregnant again and/or some other symptoms of the disease appear.

A year ago I had a pulmonary embolism and seven months ago I stop taking anticoagulants. My question is, how much should I wait for getting pregnant and for this problem not to happen again?

If you don’t have sequelae (3% of the patients stay with shortness of breath after a pulmonary embolism), you can get pregnant now. Nonetheless, as soon as you know that you are pregnant, you should contact your doctor. He/she will decide if you should receive any phrophylaxis during your pregnancy. Pregnancy and delivery are a risk factor for developing a new venous thrombosis or pulmonary embolism. However, there are effective methods for prevention.

I am pregnant and I would like to know if low molecular weight heparin injections have any problem over the fetus

You don’t need to worry. Low molecular weight heparin in prophylaxis dose does not have any risk on the fetus. They are efficient and secure.
