INFORMATION FOR WOMEN WHO HAVE CENTRAL VEIN THROMBOSIS DURING PREGNANCY OR BREASTFEEDING

 

What is central vein thrombosis during pregnancy?

Thrombosis is the medical word for a blood clot that occurs within a blood vessel, which obstructs blood flow through the vessel. Clotting can occur in arteries, the vessels that carry blood away from the heart to nourish body tissues, but they also can develop in veins, the vessels that carry blood back to the heart. Whereas arterial thrombosis usually results from a disease process in the wall lining the inside of the vessel, venous thrombosis usually results from problems with the coagulation system, the network of biochemical pathways that produce clots to stop bleeding. The coagulation system includes several proteins called clotting factors (which promote clotting), anti-coagulation factors (which slow the clotting process), and platelets (thrombocytes), special cells that carry some of the clotting agents and that also become part of the clot (thrombus). Inadequate clotting means that a person can hemorrhage, bleed heavily, which threatens life, but too much tendency to form clots is not good either. The coagulation system needs to be balanced in a kind of Goldilocks zone, with just the right amount of clotting. Various situations can throw this off, including pregnancy, due to changes in hormones, the cardiovascular system, and other factors.
