Heparins, etc: Unfractionated Heparin (UFH) can be given IV or sq (as prophylaxis) and was used historically and is used now especially if want to turn on/off and be able to reverse it (w/ protamine). Enoxaparin (lovenox) is a low molecular weight Heparin (lmwh) that can be given subcutaneously (sq) for prophylaxis or treatment. Aspirin is used more to prevent arterial (mi, tia, stroke) not venous clots.

LMWH is used sometimes in patients with pregnancy and a history of stillbirths. Here is an old reference: http://www.medicalnewstoday.com/releases/7847.php Institutions with "high risk" OB's and hematologists that work with them can comment more.

Also, ASA is being used after surgergy to prevent venous thromboembolism (http://www.ncbi.nlm.nih.gov/pubmed/22621626) and is used in the prevention of blood clots for patients on the chemotherapy lenalidomide (Revlimid) and dexamethasone.
