thromboembolism in pregnancy

Venous thrombosis and thromboembolism (VTE) remain the leading cause of direct maternal deaths, occurring within 42 days of the end of pregnancy in the UK. Pregnancy is associated with an overall 10-fold higher incidence of VTE than in the non-pregnant state and has been reported to reach up to 30-fold higher in the puerperium. This increased risk is further exacerbated by maternal obesity in a relationship that appears to be proportional with increasing Body Mass Index (BMI). Maternal obesity is the most common health problem in women of reproductive age with clinically significant health risks to women during pregnancy and after delivery...

Cerebral venous thrombosis is part of the so-called thrombosis in unusual sites. It is defined as an occlusion in the cerebral venous territory. Its incidence is progressively increasing, especially in developing countries. It is more frequently observed in young women, with hormonal factors such as pregnancy or hormonal contraception being significant risk factors in the development of this condition. The clinical presentation will depend fundamentally on the topography of the thrombosis, with a confirmatory diagnosis based mainly on imaging tests...

BACKGROUND: Early reports have demonstrated an association of COVID-19 infection during pregnancy and postpartum period with coagulopathy and bleeding complications and indicated that pregnant people with COVID-19 are more likely to experience coagulopathy and venous thromboembolism. A recent report concerning such complications during the first wave of the pandemic was reassuring; however, no publications have evaluated these issues in the context of increased illness severity with the emergence of SARS-CoV-2 variants of concern...

BACKGROUND: The risk of venous thromboembolism (VTE) is increased postpartum and contributes to important morbidity and mortality. While there have been advances in evaluating diagnostic algorithms for suspected VTE during pregnancy, there is limited data for postpartum individuals. OBJECTIVE: We conducted a scoping review to describe and evaluate diagnostic strategies used to investigate suspected VTE in postpartum individuals. METHODS: A comprehensive search strategy was conducted in Ovid MEDLINE, Embase and the Cochrane Central Register of Controlled Trials (January 1, 2000-September 30, 2022) to identify original articles that reported on diagnostic strategies in postpartum individuals with suspected VTE...

Pregnancy-associated myocardial infarction is an overall uncommon event, but can be associated with significant maternal and fetal morbidity and mortality. In contrast to myocardial infarction in the general nonpregnant population, the mechanism of pregnancy-associated myocardial infarction is most commonly due to nonatherosclerotic mechanisms such as coronary dissection, vasospasm, or thromboembolism. The diagnosis of pregnancy-associated myocardial infarction can be challenging, requiring a high index of suspicion for prompt recognition and management...

BACKGROUND: Women with peripartum cardiomyopathy (PPCM) are at an increased risk of arterial and venous thromboembolic events. The review summarizes the evidence on the incidence of thromboembolic complications in women with PPCM, diagnostic approaches, related outcomes, and effects of therapies that have been used. METHODS: English articles were retrieved from Web of Science and PubMed using search terms to capture studies related to PPCM (or postpartum cardiomyopathy) and all combinations of thrombosis- and embolism-related keywords...

Venous thromboembolism (VTE) remains the leading cause of maternal mortality in pregnancy and the postpartum period. In addition to the higher pregnancy-associated baseline VTE risk, there are several well-established risk factors that can further increase the risk of VTE. At present, a thorough interrogation of these risk factors remains our only tool for estimating which pregnant people may be at an increased risk of VTE, and thus potentially benefit from thromboprophylaxis. However, an important knowledge gap still exists surrounding the duration of increased risk and the interaction of risk factors with each other...

OBJECTIVE: Cerebrovascular accidents (CVA) in childbearing-age women are rare. We aimed to evaluate the association between CVA events prior to delivery and obstetrical and neonatal outcomes. METHODS: A retrospective cohort study was conducted using data from the Healthcare Cost and Utilization Project, Nationwide Inpatient Sample (HCUP-NIS) database. All pregnant women who delivered or had a maternal death in the US from 2004 to 2014 were included in the study...

BACKGROUND: Stillbirth occurs more commonly in pregnant people with comorbid conditions and obstetric complications. Stillbirth also independently increases maternal morbidity and imparts psychosocial hazard compared with live birth. These distinct needs and burden may increase the risk for postpartum readmission after stillbirth. OBJECTIVE: To examine the risk of maternal postpartum readmission after stillbirth, in comparison with live birth, and to identify indications for readmission and associated risk factors...

Venous thromboembolism (VTE) is still reported as the leading cause of direct maternal death in pregnancy in serial international reports in developed countries. VTE risk is higher during pregnancy but is further increased by additional well-characterized risk factors. International guidelines recommend that formal VTE risk assessment should be conducted at least in early pregnancy, at delivery and when risk factors change. High quality data supporting optimal VTE prevention strategies are lacking, outside the setting of prevention of VTE recurrence...

BACKGROUND: Venous thromboembolism accounts for approximately 9% of pregnancy-related deaths in the United States. National guidelines recommend postpartum risk stratification and pharmacologic prophylaxis in at-risk individuals. Knowledge on modern rates of postpartum pharmacologic thromboprophylaxis and its associated risks is limited. OBJECTIVE: This study aimed to describe the rate of, and factors associated with, initiation of postpartum pharmacologic prophylaxis for venous thromboembolism, and to assess associated adverse outcomes...

Antiphospholipid syndrome (APS) is a systemic autoimmune disease characterized by thrombotic and non-thrombotic macro- and microvascular manifestations and pregnancy complications in the setting of persistent antiphospholipid antibodies (aPL), namely anticardiolipin antibodies, anti-β2 glycoprotein-I antibodies and lupus anticoagulant. Four decades after its first description, APS prevalence and incidence are still not completely understood due to the limited number of well-designed, population-based multi-ethnic studies...

Selecting an appropriate oral contraceptive can be challenging for healthcare professionals due to the abundance of marketed contraceptive options with different clinical and real-world effectiveness and safety profiles. Nomegestrol acetate + 17β-estradiol (NOMAC/E2) is a combined oral contraceptive (COC) that inhibits ovulation by suppressing ovarian function by a 17-hydroxy-progesterone derivative and an estrogen identical to that endogenously produced by the ovaries. This narrative review examines clinical and real-world studies of NOMAC/E2 based on a background literature search using PubMed and Google Scholar...

OBJECTIVE: Transient ischemic attack (TIA) is rare in women of reproductive age. We aimed to compare perinatal outcomes between women who suffered from a TIA to those who did not. METHODS: A retrospective population-based cohort study utilizing the Healthcare Cost and Utilization Project, Nationwide Inpatient Sample (HCUP-NIS). All women who delivered or had a maternal death in the US (2004-2014) were included in the study. Pregnancy, delivery, and neonatal outcomes were compared between women with an ICD-9 diagnosis of a TIA to those without...

BACKGROUND: Pulmonary embolism (PE) is a leading cause of pregnancy-related mortality. CT pulmonary angiogram (CTPA) is the first-line advanced imaging modality for suspected PE in pregnancy at institutes offering low-dose techniques; however, a protocol balancing safety with low dose remains undefined. The wide range of CTPA doses reported in pregnancy suggests a lack of confidence in implementing low-dose techniques in this group. PURPOSE: To define and validate the safety, radiation dose and image quality of a low-dose CTPA protocol optimised for pregnancy...

Introduction A pulmonary embolism (PE) occurs when an embolus that has traveled through the venous system from another part of the body obstructs an artery in the lungs. Chest pain, especially while breathing in, coughing up blood, and shortness of breath are all possible signs of PE. There could also be signs of a blood clot in the leg, like a painful, swollen, red, and warm leg. As a high-risk group, particularly during childbearing age, the aim of this study is to evaluate the general awareness of females regarding PE and identify areas of knowledge deficit and factors contributing to their awareness level...

BACKGROUND: The American Heart Association (AHA), in conjunction with the National Institutes of Health, annually reports the most up-to-date statistics related to heart disease, stroke, and cardiovascular risk factors, including core health behaviors (smoking, physical activity, nutrition, sleep, and obesity) and health factors (cholesterol, blood pressure, glucose control, and metabolic syndrome) that contribute to cardiovascular health. The AHA Heart Disease and Stroke Statistical Update presents the latest data on a range of major clinical heart and circulatory disease conditions (including stroke, brain health, complications of pregnancy, kidney disease, congenital heart disease, rhythm disorders, sudden cardiac arrest, subclinical atherosclerosis, coronary heart disease, cardiomyopathy, heart failure, valvular disease, venous thromboembolism, and peripheral artery disease) and the associated outcomes (including quality of care, procedures, and economic costs)...

Pulmonary embolism, while a rare and life-threatening condition, is increasingly recognized in the context of pregnancy, particularly when compounded by infections such as coronavirus disease 2019 (COVID-19). This case report describes a 34-year-old pregnant woman, at 32 weeks of gestation, who developed COVID-19-related coagulopathy despite prophylactic treatment with low molecular weight heparin (LMWH). Admitted with symptoms of breathlessness, fever, and cough, she was diagnosed with COVID-19 and subsequently developed pulmonary embolism...

Hypertensive disorders of pregnancy (HDP) and pre-pregnancy hypertension contribute to maternal morbidity and mortality. We examined the association of HDP and pre-pregnancy hypertension with subsequent venous thromboembolic (VTE) events. The retrospective cohort study included 444,859 women with ≥1 live, singleton birth in South Carolina (2004-2016). Hospital and emergency department visit and death certificate data defined incident VTE, HDP, and pre-pregnancy hypertension. Birth certificate data also defined the exposures...
