Women who are anticoagulated.
Matched case controls.
We intend to conduct a prospective cohort study at Oregon Health and Science University and the University of Hawaii. This study will not be blinded and subjects will not be randomized. Women will be approached about this study after they have made a decision to terminate the pregnancy and have completed the preoperative history and physical examination and surgical consenting process. For patients who are receiving anticoagulant medications, the decision to continue anticoagulant therapy or interrupt it will be made by the patient's physician, independently of this study.
We will recruit women who continue on anticoagulant therapy (heparin, low molecular weight heparin, or warfarin) without interruption for the surgical procedure. Our control group will consist of women who are not on anticoagulant treatment. This is a matched study and our control group will be matched for gestational age, parity, and cesarean section history.
