The case is presented of a 29-year-old primiparous woman who was COVID-19-positive at 34 weeks of gestation and who developed severe acute respiratory distress syndrome. After a four-day history of fever and mild dyspnea, she was referred to hospital. Ciclesonide, dexamethasone, heparin sodium, and sulbactam/ampicillin were initiated, followed by remdesivir and tocilizumab. On the fourth day after admission (at 34 weeks 5 days of gestation), respiratory failure required ventilator management. An emergency cesarean section was performed and a 2565-g male infant was delivered with an Apgar score of 8/8 and negative COVID-19 status . However, on the following day the patient's respiratory condition deteriorated and mechanical ventilation was initiated. Subsequently, her respiratory condition quickly improved and mechanical ventilation was terminated 4 days after intubation. She was discharged 12 days after cesarean delivery. Our case provides additional evidence that raises concerns regarding the unfavorable maternal consequences of COVID-19 infection during pregnancy.
We conclude that thyroid function should be monitored closely after HSG using lipiodol to detect the development of hypothyroidism, particularly in patients with subclinical hypothyroidism, and TSH and FT4 measurements should be performed before HSG to identify patients at risk for hypothyroidism.
Secondary postpartum hemorrhage (PPH) and postabortion hemorrhage are rare complications. Retained products of conception (RPOC) is among the most common causes of both secondary PPH and postabortion hemorrhage. Other less common causes of secondary PPH are uterine vascular abnormalities such as arteriovenous malformations and pseudoaneurysms. These are usually related to a history of a procedure such as dilation and curettage or cesarean delivery. Subinvolution of the placental site is an idiopathic cause of secondary PPH; this condition may be underrecognized and therefore could have a higher incidence than currently reported. Gestational trophoblastic disease is rare but commonly presents as secondary PPH and resembles RPOC in radiologic appearance. The first-line imaging modality for secondary PPH is ultrasound, but computed tomography and magnetic resonance imaging may be used if the ultrasound findings are indeterminate. Angiography is an important tool for the definitive diagnosis of uterine vascular abnormalities. Appropriate management requires radiologists to be familiar with the multimodality imaging features of secondary PPH or postabortion hemorrhage.
Warfarin-associated fetal hemorrhage is a fatal event. We report the case of a 39-year-old woman who had been taking warfarin for 23 years since undergoing mitral valve replacement. Thereafter, when she was found to be pregnant, the medication was switched to heparin from 6 to 21 weeks of gestation. Following this, she was prescribed oral warfarin again (3.5 mg per day), with a strict control of prothrombin time/international normalized ratio (PT/INR). At 23 weeks of gestation, fetal intracranial hemorrhage occurred because of maternal exposure to warfarin. Maternal PT/INR does not correlate well with the activity of warfarin in the fetus and currently, there is no direct way to prevent fetal intracranial hemorrhage. Hence, further research on the optimal coagulation therapy in pregnant women with valve replacement should be encouraged.
Uterine arteriovenous malformation (AVM) can cause massive hemorrhage and is often treated with uterine artery embolization (UAE), which may lead to ovarian insufficiency. Thus, avoiding UAE should be considered, particularly in women undergoing fertility treatments. We present three women diagnosed with postmiscarriage AVM on color Doppler by transvaginal ultrasound imaging. They had no genital bleeding and a small mass, measuring 16–22 mm. If estradiol was >300 pg/mL when AVM was diagnosed, then a gonadotropin-releasing hormone agonist was administered. All three women underwent follow-up observation, revealing spontaneous mass disappearance. To avoid ovarian insufficiency risk with UAE, conservative management and close follow-up observation should be considered in patients with AVM without bleeding, particularly during the fertility treatment.
Massive subchorionic thrombohematoma (MST), termed Breus’ mole, is a rare condition in which a large maternal blood clot separates the chorionic plate from the villous chorion. Common complications of MST include fetal growth restriction, preeclampsia, and intrauterine fetal death. Here, we present a case of a 17-year-old Japanese woman referred to our institution at 21 weeks of gestation. Ultrasound examination revealed a large placental mass with mixed high and low echogenicity measuring approximately 7.6 cm in thickness. Doppler examination showed absence of end-diastolic velocity of the umbilical artery. At 22 weeks of gestation, the patient had a stillbirth weighing 138g. The placenta weighed 502 g and was 8 cm thick, and the total blood loss was 270 g. Macroscopic examination revealed that a subchorionic blood clot measuring 12 cm × 5 cm covered a large portion of the placenta with well-defined margins on the fetal surface. Microscopic examination revealed an intervillous hematoma and fibrinous deposits directly beneath the chorionic plate with adjacent compressive effects. Based on these findings, MST was diagnosed. Because MST is rare, it must be considered in the differential diagnosis of parental conditions. Magnetic resonance imaging can be optimal for diagnosing MST when ultrasound diagnosis is difficult.
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.
