Summary Thirty‐four patients with antenatal venous thromboembolism seen in Dundee Royal Infirmary between 1960 and 1969 are reviewed in an attempt to define the patient at risk. No pregnant woman is immune but older parous patients with a history of venous trouble and subjected to rest in bed are likely to develop the condition. The diagnosis of deep venous thrombosis and the medical management of patients with antenatal deep venous thrombosis are discussed. There may be a place for the use of low molecular weight Dextran during labour and in the early puerperium. Although postpartum recurrence of deep venous thrombosis did not occur significantly more frequently in patients who had received stilboestrol to suppress lactation, all the cases of puerperal pulmonary embolism occurred in patients who had received either stilboestrol or hexoestrol. It appears unwise to administer substances which are known to raise blood clotting factors to patients who are already notably susceptible to venous thrombosis. Antepartum and postpartum anticoagulation regimens are suggested.
