Introduction: Maternal obesity presents significant health risks to mothers and their fetuses. This study aimed to determine the proportion, associated factors and outcomes of maternal obesity among pregnant women in Klang Valley, Malaysia. Methods: A retrospective cross-sectional study was conducted between January 2018 and March 2018 using secondary data from the Malaysian National Obstetric Registry (NOR) for the year 2015. All pregnant women with first-trimester booking at 12 weeks and below that were registered with the NOR and met the inclusion and exclusion criteria were included in the study. Descriptive statistics and multiple logistic regression analysis were used. Data were analysed using SPSS version 22.0. A total of 2113 respondents were included in this study to determine the proportion, associated factors and outcomes of maternal obesity. Regarding the univariate and multivariate analyses, respondents were classified into two groups: normal and obese. The obese group comprised overweight and obese mothers. The underweight group was excluded in the subsequent analysis. Results: Out of the 2113 respondents, 7.1% were underweight, 41.7% were of normal weight, 28.6% were overweight, 15.9% were in obese class I, 4.6% were in obese class II, and 2.1% were in obese class III according to the WHO (1995) reference. However, when the MOH (2003) cutoff point was used, there was a marked increase in the proportion of respondents in the overweight categories by 2.7% and obesity class I by 12.8%. The Indian (AdjOR 2.06, 95% CI: 1.11, 3.83, p=0.021) and Malay (AdjOR 1.75, 95% CI: 1.02, 3.00, p=0.040) ethnicities, as well as both multiparity (AdjOR 1.46, 95% CI: 1.23, 1.73, p <0.001) and grand multiparity (AdjOR 2.41, 95% CI: 1.78, 3.26, p <0.001), were significantly associated with maternal obesity. There were significant association between maternal obesity with hypertensive disorder in pregnancy (p=0.025), caesarean section delivery (p=0.002) and macrosomic infant (p <0.001). Conclusion: The identification of risk factors for maternal obesity is important to facilitate intervention programmes focused on improving the pregnancy outcomes for a high-risk group of women.

Porto-spleno-mesenteric vein thrombosis is a rare, life-threatening condition of extrahepatic portal venous system thrombosis. We report a rare case of a 49-year-old lady with late presentation of acute portal vein thrombosis in a non-cirrhotic liver with an incidental finding of left adnexal teratoma. She presented with a one-week history of severe abdominal pain associated with vomiting and diarrhea. She gave no history of prior risk for venous thromboembolism or liver diseases. Physical examination revealed a tender mass extending from suprapubic to left iliac fossa. Abdominal computed tomography scans showed a well-defined fat-containing left adnexal mass, likely a benign teratoma, with no involvement of surrounding structures or calcification. There was evidence of porto-splenic-mesenteric vein thrombosis with liver infarction, bowel and splenic ischemia. Management of the extensive thrombosis causing multi-organ failure includes resuscitation, supportive care and treatment of thrombosis. Treatment options include early anticoagulation and if feasible, thrombolysis
