Background: Rasmussen's encephalitis (RE) is a rare neurologic disorder characterized by progressive seizures and unilateral cerebral atrophy with onset during childhood and unknown etiology. When medical therapy appears refractory, surgical disconnection of the affected hemisphere is indicated. Quality of life after functional hemispherectomy is largely good, affected females may therefore pursue pregnancy. However, data on pregnancy and delivery in RE post hemispherectomy is extremely rare. Case presentation: We present the case of a patient with left functional hemispherectomy for RE at the age of seven, who experienced two successful pregnancies. In both pregnancies, her post-surgical symptoms including right-sided spasticity, cephalgia, dizziness, and impairment of vision and speech deteriorated but improved to pre-pregnancy level after delivery. Neurologic sequelae post-hemispherectomy overlapped with clinical signs of preeclampsia and required close diagnostic surveillance during both pregnancies. Conclusion: There are no data on the interaction between RE, hemispherectomy and pregnancy, making maternal and fetal risk assessment difficult. Due to the complexity of the condition and symptoms, management of RE in pregnancy remains highly challenging and requires an interdisciplinary approach. This is the first case description of two successful pregnancies in a woman with RE and status post-hemispherectomy. Further evidence is urgently required to improve counseling and management of affected women. [ABSTRACT FROM AUTHOR]

Objectives: Pregnancies in women with Fontan circulation are on the rise, and they are known to imply high maternal and fetal complication rates. The altered hemodynamic profile of univentricular circulation affects placental development and function. This study describes placental sonomorphologic appearance and Doppler examinations and correlates these to histopathologic findings and pregnancy outcomes in women with Fontan circulation. Methods: A single-center retrospective analysis of pregnancies in women with Fontan circulation was conducted between 2018 and 2023. Maternal characteristics and obstetric and neonatal outcomes were recorded. Serial ultrasound examinations including placental sonomorphologic appearance and Doppler studies were assessed. Macroscopic and histopathologic findings of the placentas were reviewed. Results: Six live births from six women with Fontan physiology were available for analysis. Prematurity occurred in 83% (5/6 cases) and fetal growth restriction and bleeding events in 66% (4/6 cases) each. All but one placenta showed similar sonomorphologic abnormalities starting during the late second trimester, such as thickened globular shape, inhomogeneous echotexture, and hypoechoic lakes, resulting in a jelly-like appearance. Uteroplacental blood flow indices were within normal range in all women. The corresponding histopathologic findings were non-specific and consisted of intervillous and subchorionic fibrin deposition, villous atrophy, hypoplasia, or fibrosis. Conclusions: Obstetric and perinatal complication rates in pregnancies of women with Fontan circulation are high. Thus, predictors are urgently needed. Our results suggest that serial ultrasound examinations with increased awareness of the placental appearance and its development, linked to the Doppler sonographic results of the uteroplacental and fetomaternal circulation, may be suitable for the early identification of cases prone to complications.

Background: To report on prophylactic therapy for hyperfibrinolysis with tranexamic acid (TXA) during expectant management (EM) in the placenta accreta spectrum (PAS). Methods: This is a monocentric retrospective study of women with PAS presenting at our hospital between 2005 and 2021. All data were retrospectively collected through the departmental database. Results: 35 patients with PAS were included. EM was planned in 25 patients prior to delivery. Complete absorption of the retained placenta was seen in two patients (8%). Curettage was performed in 14 patients (56%). A hysterectomy (HE) was needed in seven (28%) patients; 18 patients (72%) underwent uterus-preserving treatment without severe complications. The mean duration of EM was 107 days. The mean day of onset of hyperfibrinolysis and beginning of TXA treatment was day 45. The mean nadir of fibrinogen level before TXA was 242.4 mg/dL, with a mean drop of 29.7% in fibrinogen level. Conclusions: Our data support EM as a safe treatment option in PAS. Hyperfibrinolysis can be a cause of hemorrhage during EM and can be treated with TXA. To our knowledge, this is the first cohort of patients with EM of PAS in whom coagulation monitoring and use of TXA have been shown to successfully treat hyperfibrinolysis. [ABSTRACT FROM AUTHOR]
