Q: Blood clots and pregnancy: Is my pregnancy likely to be complicated by this same problem?
A: Deep vein thrombosis (DVT) is a blood clot that forms in the venous system. The clot may stay in one area, such as the legs, causing pain and swelling; or it may migrate to another part of the body and become life threatening. Most serious of these scenarios is a pulmonary embolism, a blood clot that lodges in the lung. Since you have a history of DVT, you are at slightly greater risk of developing it during your pregnancy. Fortunately, some anti-coagulant drugs can safely be used in pregnancy to help prevent and treat this condition; your doctor will decide whether this is appropriate for you. Be sure to tell your doctor immediately if you experience any pain or swelling in your extremities.
