Background: Pregnancy represents a major risk factor for deep vein thrombosis (DVT). Most coagulation/fibrinolysis markers currently utilized change during pregnancy, and therefore they cannot accurately evaluate thrombotic events in pregnancy because the rate of false positive results is high. Fibrin monomer complex (FMC) has recently become widely available for diagnosing DVT. The present study examined whether FMC is suitable for evaluating thrombotic status in pregnancy. Methods: Concentrations of FMC and other haemostatic markers were investigated in 87 pregnant women without major complications at early, mid- or late pregnancy. FMC concentrations were also measured in 127 normal non-pregnant women, and in one woman who developed DVT after delivery. Results: In normal pregnant women, FMC concentrations were unchanged during early or mid-pregnancy and slightly elevated during late pregnancy. Concentrations were within reference range in most cases, and none exceeded the cut-off value for DVT. In contrast, thrombin-antithrombin complex (TAT) and D-dimer (DD) concentrations were significantly elevated in late pregnancy, and median values exceeded reference ranges. The DVT case displayed significantly elevated FMC concentrations. Conclusions: Changes in FMC concentrations during normal pregnancy are minimal compared with other haemostatic markers. Because the rate of false positivity is lower, FMC could be a potential marker of thrombotic status in pregnancy rather than TAT and DD.

Summary Objective: To determine the diagnostic accuracy of ultrasound to detect deep--vein thrombosis in pregnant patients. Method: We searched Pubmed, LILACS, Scopus, Google Scholar and System for Information on Grey Literature from inception to April 2016. The reference lists of the included studies were analyzed. Original articles from accuracy studies that analyzed ultrasonography to diagnose deep-vein thrombosis in pregnant women were included. Reference standard was the follow-up time. The QUADAS-2 score was used for quality assessment. Results: Titles and summaries from 2,129 articles were identified. Four studies that evaluated deep-vein thrombosis in pregnant women were included. In all, 486 participants were enrolled. High risk of bias was seen in three out of four studies included regarding flow and timing domain of QUADAS-2. Negative predictive value was 99.39%. Conclusion: Accuracy of ultrasonography to diagnose deep-vein thrombosis in pregnant women was not determined due to the absence of data yielding positive results. Further studies of low risk of bias are needed to determine the diagnostic accuracy of ultrasonography in this clinical scenario.

Pregnancy and the puerperium are associated with a 10-fold increase in the risk of venous thromboembolism, comprising deep vein thrombosis and pulmonary embolism, compared to the non-pregnant state. Pulmonary embolism has been the leading direct cause of maternal mortality in most of the United Kingdom’s triennial Confidential Enquiries into Maternal Deaths over the past 30 years, attesting to the importance of prevention and prompt diagnosis and treatment of venous thromboembolism during pregnancy and following delivery. The diagnosis of venous thromboembolism is challenging in pregnancy because it can be difficult to distinguish features of venous thromboembolism, such as leg swelling and breathlessness, from those of normal pregnancy, and there are no validated clinical scoring systems. All women should undergo risk assessment for venous thromboembolism in early pregnancy, at the time of hospital admission or change in clinical condition, and after delivery.

Venous thromboembolism (VTE) is a leading cause of maternal mortality in the western developed world. VTE may present as deep vein thrombosis (DVT) or pulmonary embolism (PE) but if untreated can result in fatal PE. Although fatal PE is clearly the most significant consequence of VTE in pregnancy, DVT also often leads to morbidity related to the development of post-thrombotic syndrome (PTS). Pregnancy is an independent risk factor for VTE and the risk of VTE is 4–10 fold higher in pregnant women than in non-pregnant women of similar age. The puerperium represents a time of even higher risk. It is clear that many additional high-risk situations in pregnancy lower the threshold for thrombosis and warrant measures to prevent VTE and its complications. Risk factors for pregnancy-related VTE may be inherited or acquired. Acquired risk factors may be specifically related to the pregnancy or may have developed prior to pregnancy. Well-documented risk factors for pregnancy-related VTE include delivery by Caesarean section, previous VTE, and inherited or acquired thrombophilia. Other risk factors that have been identified include obesity, multiparity, multiple gestation, pre-eclampsia and medical conditions, such as sickle cell disease, that predispose to VTE. Our ability to diagnose VTE overall is poor as presenting signs and symptoms are extremely varied and unreliable. This is further complicated in pregnancy where signs and symptoms suggestive of VTE are common and invasive testing is more complicated. It is essential that physicians be vigilant in monitoring patients for the development of VTE and maintain a low threshold for considering thromboprophylaxis. Guidelines have recently been published by several medical societies to help with these difficult decisions. In this review the risk factors for the development of VTE in pregnancy will be discussed and guidelines for risk assessment presented. Management of patients who develop VTE in pregnancy is also outlined.

SummaryIn order to evaluate its daily variability and reliability, impedance phlebography was performed daily or on alternate days on 61 patients with deep vein thrombosis, of whom 47 also had 125I-fibrinogen uptake tests and 22 had radiographic venography. The results showed that impedance phlebography was highly variable and poorly reliable. False positive results were noted in 8 limbs (18%) and false negative results in 3 limbs (7%). Despite its being simple, rapid and noninvasive, its clinical usefulness is doubtful when performed according to the original method.

Physiological changes in lipoprotein levels occur in normal pregnancy. Women with hyperlipoproteinemia are advised to discontinue statins, fibrates already when they consider pregnancy up to and including breast-feeding the newborn, because of the fear for teratogenic effects. Hypertriglyceridemia in pregnancy can rarely lead to acute pancreatitis. Management of acute pancreatitis in pregnant women is similar to that used in non-pregnant patients. Further large cohort studies are needed to estimate the consequence of supraphysiologic hyperlipoproteinemia or extreme hyperlipoproteinemia in pregnancy on the risk for cardiovascular disease later in life.

Venous thromboembolism, which involves venous thrombosis and pulmonary embolism, is a leading cause of morbidity and mortality in hospitalized patients and is being seen with increasing frequency in outpatients. This chapter discusses the risk factors, etiology, classification, pathophysiology, natural history, prognosis, diagnosis (including venous thrombosis, recurrent venous thrombosis, and pulmonary embolism), prophylaxis, and treatment of venous thromboembolism (including the pharmacology of antithrombotic agents), as well as venous thromboembolism in pregnancy and miscellaneous thromboembolic disorders (including thrombosis of unusual sites).  This review contains 8 figures, 16 tables, and 79 references.
