The 166 pregnancies resulted in 159 live infants. There was a significantly higher risk of preterm delivery (13% vs. 6%) and intrauterine growth restriction (4.4% vs. 3.5%). Delivery by cesarean section was more common in these high\u2010risk LMWH\u2010treated pregnancies (33.1%) than in untreated pregnancies (19.2%). In the LMWH\u2010group, the occurrence of PPH was 7.2% compared with 8.8% in the matched untreated control group (<jats:italic>p<\/jats:italic> = 0.675). None of the events in the LMWH group were serious and all 166 women were in good health at discharge. <jats:italic>Conclusions.<\/jats:italic> Individually dosed LMWH is well tolerated and safe for prophylaxis and treatment of thromboembolic complications during pregnancy, delivery and the postpartum period.<\/jats:p>","DOI":"10.3109\/00016340903370098","type":"journal-article","created":{"date-parts":[[2009,12,19]],"date-time":"2009-12-19T05:22:28Z","timestamp":1261200148000},"page":"15-21","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Venous thromboembolism in pregnancy: prophylaxis and treatment with low molecular weight heparin"],"prefix":"10.1111","volume":"89","author":[{"given":"ANITA SYLVEST","family":"ANDERSEN","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J\u00d8RGEN G.","family":"BERTHELSEN","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"THOMAS","family":"BERGHOLT","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2010,12,31]]},"reference":[{"key":"e_1_2_6_2_2","volume-title":"Saving mothers' lives: reviewing maternal deaths to make motherhood safer \u2013 2003\u20132005.
