Rationale:Vein of Galen aneurysmal malformation (VGAM) is a rare complex malformation of the cerebral vascular system consisting of arteriovenous shunts between the vein of Galen and the cerebral arteries.Patient concerns:We present the case of a 31-year-old pregnant woman, para 1, gravida 1.Diagnoses:At 26 weeks’ gestation who was examined for an anechoic mass on the cerebral median midline with color and pulsed Doppler. She presented with positive flow on the color and pulsed Doppler test, associated with hydrocephalus, cortical hypoplasia, cardiomegaly, jugular vein distension.Interventions:No intervention for VGAM was done.Outcomes:This case of a VGAM was associated with negative prognostic factors.Lessons:The ultrasound color Doppler together with the 3D power Doppler allowed reconstruction of the vascular connections and of the relationship of these with other anatomical structures, which contributed to establishing the prognosis.
HELLP syndrome, also known as the syndrome of hemolysis, elevated liver enzymes, and low platelets, represents a severe pregnancy complication typically associated with hypertension. It is associated with increased risks of adverse complications for both mother and fetus. HELLP occurs in 0.2–0.8% of pregnancies, and, in 70–80% of cases, it coexists with preeclampsia (PE). Both of these conditions show a familial tendency. A woman with a history of HELLP pregnancy is at high risk for developing this entity in subsequent pregnancies. We cannot nominate a single worldwide genetic cause for the increased risk of HELLP. Combinations of multiple gene variants, each with a moderate risk, with concurrent maternal and environmental factors are thought to be the etiological mechanisms. This review highlights the significant role of understanding the underlying pathophysiological mechanism of HELLP syndrome. A better knowledge of the disease’s course supports early detection, an accurate diagnosis, and proper management of this life-threatening condition.
Gestational diabetes mellitus is an important healthcare problem with serious implications both to the mother and to the foetus. The necessity of clear screening criteria for the pregnant woman and also identifying from an early stage the risk groups can be beneficial instruments for better management of gestational diabetes. The present report identify the main screening criteria for patients at risk for gestational diabetes and the therapeutic-nutritional therapy for women that have gestational diabetes. The different diagnostic criteria, as well as the new instruments through which these criteria can be applied, are still heterogeneous, and it is necessary to unify and promote them. The prevalence of gestational diabetes has significantly increased in recent years, and this has led to an increase in the direct and indirect costs of healthcare. Establishing the optimal time and initiating the correct treatment is critical to achieving glycemic control and to minimize the impact on fetal development and perinatal complications.
This review provides a brief clinically relevant review of pheochromocytoma in pregnancy, to raise awareness among doctors in obstetrics and the aim is to serve as the first point of reference when confronted by their presence. Pheochromocytomas are neuroendocrine, catecholamine-secreting tumours. Despite having the highest incidence rate among other hormone-secreting adrenal tumours, they remain rare especially when associated with pregnancy. The non-specific presentation of pheochromocytomas, the difficulties in their diagnosis during pregnancy as well as the high maternal and fetal mortality rates associated with them, present a challenge. Clinical suspicion and meticulous patient history-taking remain the primary lines of defense, while biochemical proof of catecholamine excess (or their metabolites) and imaging-based localisation of the tumour are required for diagnosis. Antenatal diagnosis and complete localisation of the tumour increase the likelihood of successful outcomes for both mother and newborn. Magnetic resonance imaging (MRI) remains the method of choice during pregnancy without excluding the use of ultrasound. Treatment goals should include the avoidance of hypertensive crises while maintaining adequate uteroplacental circulation. The target blood pressure is not strictly defined but is in line with the general guideline addressing chronic hypertension during pregnancy. Antihypertensive medications remain the cornerstone in managing pheochromocytoma. As a first-line, the α-adrenergic, nonselective antagonist phenoxybenzamine is the most frequently used agent, while α1-selective adrenergic antagonists with or without the addition of β-or β1-blockers are also prescribed in certain cases, rendering calcium channel blockers as 'second-choice'. Blood-pressure control of the mother and the well-being of the fetus are determining factors in deciding the time of delivery, which is preferably conducted by Caesarean section. Excision of the tumour(s) remains the final treatment goal. Lifelong biochemical testing is required with or without medical treatment, to address mineralocorticoid or glucocorticoid deficits. Despite ever-improving positive outcome rates, pheochromocytoma associated with pregnancy remains a pathology with high mortality and morbidity rates.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
