Introduction: Being associated with a systemic infection, SARS-CoV-2 affects multiple organs, including the placenta. SARS-CoV-2 placentitis is a new condition that shows the destructive effects of fibrin deposition in the perivillous area, chronic histiocytic intervillositis and trophoblast necrosis after the placenta is infected with SARS-CoV-2. Until now, there have been no published reports regarding the ultrasound signs of massive perivillous fibrin deposition and the recommended monitoring for these cases., Aim: Our aim was to analyze the sonographic appearance of the placenta in a series of SARS-CoV-2 infected pregnant women during their third trimester., Material and Method: In all cases included in the present study, we performed serial obstetrical ultrasounds every seven days until delivery, followed by histopathological examination of the placenta postpartum., Results: In women with intrauterine growth restriction (IUGR), sonographic images of the placentas revealed that they matured faster within three weeks of receiving a COVID-19 diagnosis and reached a more rapid senescence. In all cases, there was a gradual increase in placental calcification from week to week, but only in pregnant women with a grade 3 placenta at the moment of inclusion in the study the deterioration was severe, leading to placental insufficiency and subsequently to IUGR., Conclusion: The cases who had an increased placental degree at the time of infection were associated with abnormally rapid placental aging. These aspects can be evaluated sonographically.

Located under the cerebral hemispheres and draining the anterior and central regions of the brain into the sinus of the posterior cerebral fossa, the vein of Galen aneurysmal malformation is considered to be a rare cause of hydrocephaly. The presence of this condition in the neonatal period typically includes intractable heart failure and a poor prognosis. We report a case of aneurysm of the vein of Galen diagnosed prenatally at 28 weeks of gestation, with the delivery at term by caesarean section of a female infant. Sonographically, the vein of Galen appeared in the mid-sagittal plane, large, supratentorial, non-pulsatile; on color Doppler, the structure filled with bright color, reflecting a turbulent venous flow. A low grade of ventriculomegaly was present during the evolution of pregnancy; regarding the cardiovascular function, an intrauterine right cardiac insufficiency overlapped a tricuspid regurgitation and right atrial dilatation. A multidisciplinary committee decided a neonatal embolization of the aneurysm as an emergency requirement due to increased pulmonary hypertension developed in the next 24 hours after birth. After the embolization of the two main drainage vessels, the cardiac dysfunction persists. Two days later the evolution became unfavorable, leading to the necessity of the second embolization, which resulted in a 48 hours' coma and death, due to a cerebral hemorrhage secondary to thrombosis and fissure of the embolized aneurysm. The prognosis for the neonate with malformation of the Galen vein depends upon the severity of the cardiovascular status. Embolization represents actually the treatment of choice with the best results of these cases, but the mortality remains as high as 50 percent even in the most specialized centers of the world. As far as we know this is the only case of Galen aneurysmal malformation in Romania which beneficiated of embolization by interventional treatment in neonatal period.

Two main causes of arterial thrombosis are known: fi rst - atherosclerosis, extensively studied, and the second - atrial fi brillation. The lack of any risk factors and the occurrence at young age of a thrombotic event requires us to investigate possible other conditions, including inherited thrombophilia that is represented by a series of genetic disorders that increase the risk of thromboembolic disease. The role of thrombophilia in the occurrence of arterial thrombosis is inconsequential; this disorder is characterized by the tendency of developing venous thrombosis. We present a rare case of a 29 year old woman that presents an arterial thrombotic event subsequent to the caesarean section. The patient had a positive familial history for thrombotic events and a cavernous sinus thrombosis in personal history. Prophylactic treatment with unfractionated heparin throughout pregnancy was applied. At 31 weeks gestation the patient underwent cesarean surgery for nonreassuring fetal status, 2 weeks fetal intrauterine growth restriction and absent diastolic fl ow of uterine arteries. Three days post operatory arterial thrombosis is suspected. The context that led to this suspicion was paresthesia, color modifi cation of the right leg and abolished popliteal pulse. Angiographic-CT confi rmed the presumptive diagnosis. A cardiovascular, conservatory treatment was successfully applied. Considering the particularities of the presented case we discuss the occurrence of arterial thrombosis postpartum in the context of confi rmed thrombophilia by reviewing the specialized literature.
