Department of Obstetrics and Gynecology, Baylor College of Medicine, Houston,Texas, USA. ctung@mdanderson.orgBACKGROUND: Acute colonic pseudoobstruction, or Ogilvie's syndrome, is arare but serious medical and obstetric complication. When diagnosed early,treatment with expectant management or more invasive decompression is oftensuccessful. However, if not recognized promptly or managed appropriately, thiscondition can be fatal. CASE: We present an unusual case of acute colonicpseudoobstruction occurring after management of preterm labor in amonochorionic-diamniotic twin pregnancy at 29 weeks' gestation complicatedwith twin-twin transfusion syndrome. CONCLUSION: Acute colonicpseudoobstruction should be considered in the differential diagnosis in pregnantwomen who present with abdominal distention and vomiting.Aust N Z J Obstet Gynaecol. 2008 Feb;48(1):44-49.Venous thromboembolism during pregnancy and the post-partum period:Incidence and risk factors in a large Victorian health service.Sharma S, Monga D.Ballarat Health Services, Ballarat, Victoria, Australia.Background: There is a strong recommendation for post-partumthromboprophylaxis following emergency caesarean sections, particularly inoverweight women, and following prolonged labour. Aims: To analyse theincidence and epidemiological factors associated with antepartum and postpartumvenous thromboembolism in a large Victorian health service. Methods: Aretrospective study of all 6987 women delivering at Ballarat Health Servicesbetween March 1999 and June 2006. Case notes of women with confirmedvenous thromboembolism during this period were subjected to detailed analysis.The data were analysed for possible risk factors, the timing of thromboembolismin relation to the pregnancy and any correlation with thromboprophylaxis, ifadministered. Results: The rate of venous thromboembolism was 1.14 per 1000deliveries, with risk factors of age > 30 (100%), obesity (75%), previous history ofthromboembolism (62.5%) and caesarean section (37.5%). Majority of caseswere diagnosed in first trimester (62.5%), and in the right lower limb (75%). Noneof the patients had been given thromboprophylaxis. Conclusion: While theincidence and risk factors were similar to those generally quoted, a much higherincidence was found in early pregnancy, and in the right lower limb. Theimportance of meticulous screening for risk factors in early pregnancy cannot beoveremphasised.Aust N Z J Obstet Gynaecol. 2008 Feb;48(1):34-39.Symptomatic urinary stone disease in pregnancy.Cheriachan D, Arianayagam M, Rashid P.Department of Urology, Port Macquarie Base Hospital, New South Wales, andUNSW Rural Clinical School, Port Macquarie Campus, New South Wales,Australia.Background: Symptomatic urinary calculi are rare in pregnancy with an incidence
