Pilot study of fetal brain development and morphometry in prenatal opioid exposure and smoking on fetal MRI.

PURPOSE: The purpose of this study was to assess for any differences in brain maturation, structure and morphometry in fetuses exposed to opioids in utero, compared to non-opioid exposed fetuses on fetal MRI. METHODS: We performed a prospective study in pregnant women using opioids and healthy pregnant women without prenatal opioid use. We evaluated brain maturation, structure, and morphometry on second or third trimester fetal MRI and assessed group differences. RESULTS: 28 pregnant women were enrolled, 12 with opioid exposure (average gestational age 33.67, range 28-39 w), 9 of whom also smoked, and 16 without opioid exposure (average gestational age 32.53, range 27-38 w). There was a significant difference in the anteroposterior diameter of the fetal cerebellar vermis in the opioid exposed fetuses compared to non-opioid exposed fetuses (p = 0.004). There were no significant differences in brain biparietal diameter, fronto-occipital diameter, transverse cerebellar diameter and anteroposterior dimension of the pons in opioid exposed fetuses compared to non-opioid exposed fetuses. There were no abnormalities in brain maturation and no major brain structural abnormalities in the opioid exposed fetuses. CONCLUSION: Smaller fetal anteroposterior cerebellar vermian dimension was associated with in utero opioid exposure. There were no abnormalities in brain maturation or major structural abnormalities in fetuses exposed to opioids.

It Is Complex: Predicting Gastroschisis Outcomes Using Prenatal Imaging.

BACKGROUND: Gastroschisis occurs in one of 2000 births with survival rates partially contingent on intestinal complications and time to establishing feeding. Enhancements in prenatal imaging have given better insight into postnatal outcomes. The goal of this study was to examine the gastroschisis patient population at a single children's hospital in the modern era and to use prenatal ultrasound (US) to develop new prenatal prognostic indicators. METHODS: We performed a retrospective review of gastroschisis patients at a quaternary-care referral children's hospital from 2010 through 2018. We recorded demographics, prenatal data and imaging, early postnatal data, operative data, and patient outcomes. We compared patients within our cohort born with complex gastroschisis (bowel atresia/perforation) to uncomplicated gastroschisis patients. Second trimester and third trimester prenatal US were evaluated for changes in amniotic fluid level, amount of external bowel, bowel dilatation, and bowel wall edema to identify prognostic indicators of the status of the bowel at birth. For categorical variables, chi-square tests were used to assess for significance. Univariate and multivariable analyses were used to assess significance between categorical and continuous variables using medians and interquartile ranges or means. RESULTS: A total of 134 patients were included in the study: complex (n = 24), uncomplicated (n = 110). Compared with uncomplicated gastroschisis, complex patients required longer median days to feeding initiation (44 versus 10; P < 0.001), full feeding (80 versus 23; P < 0.001), length of stay (83 versus 33; P < 0.001), and total parenteral nutrition at discharge (P = 0.004). Full US data were available on 81% of patients, and partial data were identified on 19%. Prenatal US analysis showed significantly more complex patients had polyhydramnios on third trimester US (23.5%-4.3%; P = 0.018). US analysis showed these additional factors to be most associated with complex gastroschisis: large amount of external bowel on third trimester US, increase in bowel edema on third trimester US, and increase in external bowel dilation on third trimester US. Multivariable logistic regression analyses revealed amniotic fluid on third trimester US to be the most significant predictor of complex gastroschisis (P = 0.01). Polyhydramnios in combination with two-thirds of the other US factors had both sensitivity and positive predictive value for predicting complex gastroschisis of 75%. Patients with two or less of these positive US factors had high specificity (96.8%) and negative predictive value (87.5%), suggesting uncomplicated disease. There were no differences in perioperative or long-term complications in the complex group when compared with the group with uncomplicated gastroschisis. CONCLUSIONS: Polyhydramnios on third trimester prenatal US on babies with gastroschisis can predict complex gastroschisis at birth, whereas the absence of markers on prenatal US can suggest uncomplicated disease. Complex gastroschisis is associated with increased time to feeds and length of stay.

Pediatric Handlebar Injuries: More Than Meets the Abdomen.

OBJECTIVES: Injuries associated with bicycles can generally be categorized into 2 types: injuries from falling from/off bicycles and injuries from striking the bicycle. In the second mechanism category, most occur as a result of children striking their body against the bicycle handlebar. The purpose of this study was to evaluate the presentation, body location, injury severity, and need for intervention for pediatric handlebar injuries at a single level one pediatric trauma center and contrast these against other bicycle-related injuries in children. METHODS: This work is a retrospective review of the trauma registry over an 8-year period. Individual charts were then reviewed for patients' demographic factors, injury details, and other clinical/radiographic findings. Each patient was then categorized as either having a handlebar versus nonhandlebar injury. Additionally, each patient's injuries were classified according to affected body "zone(s)" and the need for intervention in relation to these injuries. During the course of chart review, several unique radiographic and history/physical findings were noted and are also reported. RESULTS: During the study period, 385 patients were identified that met study criteria. Bicycle handlebars were involved in 27.8% (107/385) of injuries and 72.2% (278/385) were nonhandlebar injuries. There were differences in injury severity score, Head Abbreviated Injury Scale, length of stay between patients with handlebar versus nonhandlebar injuries, respectively. There were also differences in incidence of injuries across most body zones between patients with handlebar versus nonhandlebar injuries. There was statistically significant difference in need for intervention for abdominal solid organ injuries among handlebar versus nonhandlebar injuries mechanisms (21.6% vs 0%; P = 0.026), respectively. Sixteen patients with a handlebar injury underwent abdominal computed tomography (CT), which found only pericolic/pelvic free fluid or were negative for any disease and had normal/mildly elevated liver function test results at the time of arrival with otherwise normal laboratory workup results. Two patients required laparotomy for bowel injury and presented with peritonitis less than 12 hours after injury. The remaining patients did not have peritonitis on examination and were discharged without operative intervention 12 to 24 hours after injury without further event. CONCLUSIONS: The bicycle handlebar is a unique mechanism of injury. The location, need for intervention, and the nature of the injury can vary significantly compared to other bicycle injuries. Handlebar injuries are more likely to cause abdominal and soft tissue injuries, whereas nonhandlebar injuries are more likely to cause extremity and skull/neck/central nervous system injuries. Because more than 20% of the reported handlebar injuries did not involve the abdomen or thoracoabdominal/extremity soft tissue as well as the variable presentation of handlebar injuries, it is imperative for the physician to consider this mechanism in all bicycle injuries. In addition, even within the same area of the body, handlebar injuries can be very different compared to nonhandlebar (i.e., orthopedic vs vascular injuries in the extremities). Physical examination and observation remain paramount when laboratory and radiographic workups are equivocal.

Placental magnetic resonance imaging Part I: the normal placenta.

Mounting evidence suggests that the placenta is involved in nearly all abnormalities of pregnancy and fetal development. Traditional imaging evaluation of the placenta by ultrasound has more recently been complemented by MRI for complex cases requiring additional information, such as in the diagnosis of the placenta accreta spectrum (placenta accreta, increta and percreta). MRI can often help delineate the safest approach to delivery and adds diagnostic certainty to enable prognostication and to avoid potentially lethal complications. Increasingly, prenatal MRI has become the purview of the pediatric imager and is becoming the standard of care for select gestational indications. However, placental MRI might be unfamiliar to the radiologist. Thus, we provide a simple and systematic approach to evaluating the placenta by MRI, to enable delivery planning and family counseling.

Placental magnetic resonance imaging Part II: placenta accreta spectrum.

The human placenta remains an enigma to many. Its position as the point of communication between distinct maternal and fetal circulations means that it must act as both source of nourishment and gatekeeper for the developing pregnancy. In vivo assessment of the placenta is perhaps the greatest challenge, yet it is most essential for diagnostic and prognostic purposes. In particular, there is a need for improved diagnostic accuracy in recognizing the invasive forms of the placenta accreta spectrum that require surgical intervention at delivery and often cesarean hysterectomy. The costs of insufficient sensitivity and specificity are high, with well-documented cases of adverse outcomes ranging from unnecessary surgery to maternal hemorrhage and even death. In Part I of this pictorial essay series, we reviewed the appearance of the normal developing placenta across gestation by MRI. With this as a background, we here consider the varied appearances of the placenta accreta spectrum (placenta accreta, increta, percreta), which is a growing challenge given the rapidly expanding number of women worldwide with history of cesarean section delivery. Accurate prenatal imaging is crucial for recognizing cases of the placenta accreta spectrum and for planning the necessary surgery.

Imaging of fetal cystic kidney disease: multicystic dysplastic kidney versus renal cystic dysplasia.

With the advent of routine prenatal imaging, the number of renal anomalies identified prenatally has significantly increased; however, the underlying etiologies of these anomalies and the clinical significance of these findings remains unclear. This confusion is especially true for the prenatal diagnosis of cystic renal changes. The terms "cystic kidney disease" and "renal cystic dysplasia" encompass myriad renal diseases. Although renal cystic dysplasia in infants shares many similarities with multicystic dysplastic kidney (MCDK), it is important to distinguish MCDK from other etiologies that would lead to renal cysts, to ensure proper patient diagnosis and appropriate counseling regarding risks and to guide clinical management. The purpose of this review is to highlight the multiple etiologies of cystic kidney disease, including genetic associations, associations with underlying syndromes, and associations with underlying anatomical abnormalities. Here we focus on prenatal imaging, associated pathological findings, and clinical significance, with an emphasis on the defining characteristics of MCDK as compared to other forms of cystic renal disease.

The growing issue of burnout in radiology - a survey-based evaluation of driving factors and potential impacts in pediatric radiologists.

BACKGROUND: Burnout in medicine, and specifically radiology, has been receiving more attention. Little data-driven literature is available regarding risk factors/causes to ultimately help guide the development of potential solutions. OBJECTIVE: To survey pediatric radiologists, a cohort with a documented high prevalence of burnout, and to understand the impact of clinical demands on nonclinical tasks and the implications of burnout on mental health. MATERIALS AND METHODS: A survey of Society for Pediatric Radiology (SPR) North America attendings was performed regarding institutional factors contributing to burnout, including call burden, clinical demands, departmental support and administrative/academic tasks. Questions regarding mental health and wellness resources were also included. Generalized linear modeling assuming binomial distribution was used for analyses with SAS 9.4. RESULTS: The response rate was 305/1,282 (24%) with 53% of respondents female. Respondents reported that both the number and complexity of clinical cases have increased since they first started practice as an attending, while the time for interpretation has not changed, P<0.0001. Using a scale of 0 (never), 1 (rarely), 2 (sometimes), 3 (frequently) and 4 (always), covering multiple hospitals (2.2) and administrative tasks (2.4) were the most stressful job factors. For those in administrative roles, the most stressful job factors were job-related tasks affected teaching duties (2.0) and decreased overall job satisfaction (2.0). Of the respondents, 52% said they know a physician affected by work stress-related mental illness and 25% know a physician who has contemplated or committed suicide. While 39% of the respondents have resources available to address burnout, only 33% utilize these resources. CONCLUSION: Increasing clinical demands and additional institutional/departmental factors play a potential role in burnout, which has serious implications for the mental health of pediatric radiologists.

Radiographic and Clinical Factors in Pediatric Patients With Surgical Small-bowel Intussusception.

BACKGROUND: When evaluating a pediatric patient with abdominal pain, identification of a small bowel-to-small bowel intussusception (SBI) on radiologic imaging can create a diagnostic dilemma. The clinical significance and need for surgical exploration of SBI is highly variable, as most of them are considered clinically insignificant. We hypothesize that combination of clinical and radiologic factors in an exclusively SBI population will yield factors that guide the clinician in making operative decisions. METHODS: A comprehensive database from a pediatric tertiary hospital was reviewed from January 1, 2011, to December 31, 2016, for any radiographic study mentioning intussusception. Results were reviewed for patients having only SBI (i.e., not ileocolic intussusception), and this comprised the study cohort. The electronic medical records for these patients were reviewed for clinical presentation variables, need for operative intervention, and identification of the intussusception during surgery. Patients with SBI due to enteral feeding tubes were excluded from the study. RESULTS: Within the study period, 139 patients were identified with an SBI on radiologic imaging. Univariate analysis yielded numerous clinical and radiologic factors highly predictive of the need for surgical intervention. However, upon multivariate analysis, only a history of prior abdominal surgery (odds ratio [OR]: 7.2; CI: 1.1-46.3), the presence of focal abdominal pain (OR: 22.1; CI: 4.2-116.3), and the intussusception length (cm; OR: 10.6; CI: 10.3-10.8) were correlated with the need for surgical intervention. CONCLUSIONS: SBI is a disease process with a highly variable clinical significance. The presence of focal abdominal pain, a history of prior abdominal surgery, and the intussusception length are the greatest predictors of the need for operative intervention. LEVEL OF EVIDENCE: Level II.

Ultrasound evaluation of right diaphragmatic eventration and hernia.

BACKGROUND: A hernia is due to a defect in the diaphragm. An eventration is due to a thinned diaphragm with no central muscle. Distinguishing right diaphragmatic hernia from eventration on chest radiographs can be challenging if no bowel loops are herniated above the diaphragm. Experience is limited with postnatal ultrasound (US) evaluation of diaphragmatic hernia or eventration. OBJECTIVE: To evaluate for specific US signs in the diagnosis of right diaphragmatic hernia and eventration. MATERIALS AND METHODS: We identified all patients (January 2007-December 2017) with right diaphragm US and surgery for eventration or hernia. We reviewed medical charts, and US images/reports for clinical presentation and diaphragm abnormalities. Surgical diagnosis was considered the reference standard. RESULTS: Seventeen children (mean age: 5 months) had US examination before surgery for hernia (n=9) or eventration (n=8). The most common presentation was respiratory distress. In the US reports, hernia was correctly diagnosed in all patients and three patients with eventration were misdiagnosed as hernia, yielding 100% sensitivity and 62.5% specificity. In a retrospective evaluation of the US studies, a combination of folding of a free muscle edge with a narrow angle waist had 100% specificity for hernia and was seen in 7/9 children with hernia. Combination of a broad angle waist and hypoechoic strip of diaphragmatic muscle covering the waist had 100% specificity for eventration and was demonstrated in 4/8 children with eventration. Five of 17 patients (31.6%) had no specific sign that differentiated hernia from eventration. CONCLUSION: On US, folding of the free edge of the diaphragm and a narrow angle waist are specific for hernia; a broad angle waist with muscle covering the elevated area is specific for eventration. Definitive differentiation between eventration and hernia may not be possible in about a third of patients.

A multifactorial severity score for left congenital diaphragmatic hernia in a high-risk population using fetal magnetic resonance imaging.

BACKGROUND: Adverse outcomes for infants born with left congenital diaphragmatic hernia (CDH) have been correlated with fetal imaging findings. OBJECTIVE: We sought to corroborate these correlations in a high-risk cohort and describe a predictive mortality algorithm combining multiple imaging biomarkers for use in prenatal counseling. MATERIALS AND METHODS: We reviewed fetal MRI examinations at our institution from 2004 to 2016 demonstrating left-side CDH. MRI findings, hospital course and outcomes were recorded and analyzed using bivariate and multivariable analysis. We generated a receiver operating curve (ROC) to determine a cut-off relation for mortality. Finally, we created a predictive mortality calculator. RESULTS: Of 41 fetuses included in this high-risk cohort, 41% survived. Per bivariate analysis, observed-to-expected total fetal lung volume (P=0.007), intrathoracic position of the stomach (P=0.049), and extracorporeal membrane oxygenation (ECMO) requirement (P<0.001) were significantly associated with infant mortality. Youden J statistic optimized the ROC for mortality at 24% observed-to-expected total fetal lung volume (sensitivity 64%, specificity 82%, area under the curve 0.72). On multivariable analysis, observed-to-expected total fetal lung volume ± 24% was predictive of mortality (adjusted odds ratio, 95% confidence interval: 0.09 [0.02, 0.55]; P=0.008). We derived a novel mortality prediction calculator from this analysis. CONCLUSION: In this high-risk cohort, decreased observed-to-expected total fetal lung volume and stomach herniation were significantly associated with mortality. The novel predictive mortality calculator utilizes information from fetal MR imaging and provides prognostic information for health care providers. Creation of similar predictive tools by other institutions, using their distinct populations, might prove useful in family counseling, especially where there are discordant imaging findings.

CONGENITAL HYPOTHYROIDISM IN A BORNEAN ORANGUTAN (PONGO PYGMAEUS) AND A SUMATRAN ORANGUTAN (PONGO ABELII).

Congenital hypothyroidism (CH) in humans is most commonly caused by disruption of thyroid gland development (dysgenesis) or an inherited defect in thyroid hormone biosynthesis (dyshormonogenesis). CH has not been previously documented in great apes. This report describes the clinical presentation, diagnosis, and treatment of CH in a 9-mo-old male Bornean orangutan (Pongo pygmaeus) and a 6-wk-old female Sumatran orangutan (Pongo abelii). Primary CH due to thyroid dysgenesis was confirmed in the Bornean orangutan using sonography and radioisotope scintigraphy. Although commercial thyroid immunoassays are not validated for use in orangutans, in comparison to age-matched controls, thyroid-stimulating hormone level was markedly elevated, and serum thyroxine (T4) and free T4 levels were markedly decreased in both cases. Oral supplementation with levothyroxine sodium resulted in noticeable clinical improvement in both orangutans within 30 days of initiating treatment.

Fetal MRI in management of complicated meconium ileus: Prenatal and surgical imaging.

OBJECTIVE: To review fetal MRI cases surgically proven to have meconium ileus (MI) and obstruction, describe the common fetal MRI findings that distinguish cases of complicated MI, and to compare these findings with surgical images and perinatal outcomes. METHOD: We performed a retrospective review of all fetal MRI examinations and the corresponding medical record from our tertiary care children's hospital over an 18-month period. Postnatal management and outcomes were reviewed for these patients, and those patients with surgical or postmortem diagnosis of complicated MI were included in the study. RESULTS: Our analysis revealed 7 cases. In this cohort, 3 imaging features of the fetal bowel were repeatedly seen: gradient appearance of intraluminal bowel contents, abnormally localized meconium signal, and collapsed appearance of the colon on MRI. Surgical diagnoses confirmed MI. All live-born infants underwent surgical repair. CONCLUSION: Fetal MRI should be included in the diagnostic algorithm of any pregnancy where fetal bowel obstruction is suspected to better risk stratify patients.

A retrospective segmentation analysis of placental volume by magnetic resonance imaging from first trimester to term gestation.

BACKGROUND: Abnormalities of the placenta affect 5-7% of pregnancies. Because disturbances in fetal growth are often preceded by dysfunction of the placenta or attenuation of its normal expansion, placental health warrants careful surveillance. There are limited normative data available for placental volume by MRI. OBJECTIVE: To determine normative ranges of placental volume by MRI throughout gestation. MATERIALS AND METHODS: In this cross-sectional retrospective analysis, we reviewed MRI examinations of pregnant females obtained between 2002 and 2017 at a single institution. We performed semi-automated segmentation of the placenta in images obtained in patients with no radiologic evidence of maternal or fetal pathology, using the Philips Intellispace Tumor Tracking Tool. RESULTS: Placental segmentation was performed in 112 women and had a high degree of interrater reliability (single-measure intraclass correlation coefficient =0.978 with 95% confidence interval [CI] 0.956, 0.989; P<0.001). Normative data on placental volume by MRI increased nonlinearly from 6 weeks to 39 weeks of gestation, with wider variability of placental volume at higher gestational age (GA). We fit placental volumetric data to a polynomial curve of third order described as placental volume = -0.02*GA3 + 1.6*GA2 - 13.3*GA + 8.3. Placental volume showed positive correlation with estimated fetal weight (P=0.03) and birth weight (P=0.05). CONCLUSION: This study provides normative placental volume by MRI from early first trimester to term gestation. Deviations in placental volume from normal might prove to be an imaging biomarker of adverse fetal health and neonatal outcome, and further studies are needed to more fully understand this metric. Assessment of placental volume should be considered in all routine fetal MRI examinations.

A comprehensive severity score for the morbidly adherent placenta: combining ultrasound and magnetic resonance imaging.

BACKGROUND: Ultrasound (US) is the first-line imaging modality to assess the morbidly adherent placenta, but sensitivity and specificity are lacking. OBJECTIVE: This investigation aims to improve diagnostic accuracy with a comprehensive score using clinical history, US, and magnetic resonance imaging (MRI). MATERIALS AND METHODS: We conducted a retrospective cohort study of pregnant women who received both transvaginal US and MRI with suspicion for morbidly adherent placenta between 2009 and 2016. US was scored with the following metrics: (i) previa, (ii) hypervascularity, (iii) loss of retroplacental clear space and (iv) lacunae. MRI was evaluated for (i) intraparenchymal vessels, (ii) abnormally dilated vessels, (iii) fibrin deposition, (iv) placental bulge and (v) bladder dome irregularity. Bayesian analysis was used to estimate the probability of morbidly adherent placenta for a given score. Diagnostic testing parameters were calculated. RESULTS: Among the 41 women with concerning imaging, histologically identified disease was confirmed in 16. The probability of morbidly adherent placenta increased with the score. At the highest US score, the probability of disease was 63.7%. With the highest MRI score, the probability of adherent placentation was 90.5%. Combining the US and MRI findings had a sensitivity of 56% and a specificity of 92%. CONCLUSION: A combined scoring system using MRI and US may accurately identify patients at risk for morbidity associated with morbidly adherent placenta.

Radiology Resident Ownership Scale (RROS): Adapting a Validated Measure of Patient Care Ownership to the Radiology Context.

RATIONALE AND OBJECTIVES: The aim of this study was to develop a validated instrument to measure radiology residents' sense of psychological ownership of patient care. MATERIALS AND METHODS: A previously validated measure of patient care ownership was adapted through a two-step process of expert review and revision by six academic radiology faculty. An online, anonymous survey was distributed to 64 residents and fellows at the end of three consecutive four-week long rotations. We calculated Cronbach's α to determine the scale's internal consistency, performed exploratory factor analysis to identify possible subscales, and conducted bivariate and correlational analysis to establish construct validity. RESULTS: The 11-item ownership scale demonstrated good internal consistency (Cronbach's α = 0.93), and three subscales were identified corresponding to assertiveness, conscientiousness, and confidence/perceived competence. Sense of ownership was significantly associated with training level, prior experience in the type of rotation, stress, sleep, burnout, peer support, relationships with clinical staff, and recognition by department. We found no significant association between ownership and age, gender, type of rotation, site of rotation, type of residency, perceived interruption frequency, or remote work frequency. CONCLUSION: The radiology resident patient care ownership scale demonstrates good internal consistency and preliminary evidence of validity. After further validation, we expect the scale to be a valuable tool in evaluating interventions aimed at increasing radiology residents' sense of ownership.

Placental volume in pregnant women with opioid use: prenatal MRI assessment.

OBJECTIVE: Opioid use in pregnant women is a growing public health concern and is shown to be associated with lower infant birth weights. Placental volume changes in prior studies correlated with various maternal and fetal conditions. We aimed to identify differences between placental volumes in pregnant women with opioid use, and control pregnant women without drug use. METHODS: We prospectively recruited 27 healthy pregnant women and 17 pregnant women with opioid use disorder who were on medication-assisted treatment (MAT). All women underwent placenta/fetal MRI at 27-39 weeks gestation on a 3 Tesla MR scanner. Placental volumes were measured in a blinded fashion using a previously validated technique. Multiple linear regression was used to identify associations of placental volume with multiple maternal and fetal clinical factors. The significance threshold was set at p < .05. RESULTS: Placental volume was significantly associated with gestational age at MRI (p < .0001), fetal sex (p = .027), MAT with smoking (p = .0008), MAT with polysubstance use (p = .01), and maternal BMI (p = .032). Placental volume was not associated with opioid MAT alone in our cohort. CONCLUSION: For pregnant women on medication-assisted treatment for opioid use disorder, there was no significant difference in placental volume compared to healthy pregnant women. However, concomitant smoking and polysubstance use in the setting of medication-assisted treatment may be detrimental to placental health. To our knowledge, this is the first study assessing placental volume in opioid use on prenatal MRI. These results support the benefit of medication-assisted treatment during pregnancy; however additional studies are needed to further elucidate the impact of opioid use on placental and fetal development and postnatal outcomes.

Fetal Cerebral Sinovenous Thrombosis and Dural Sinus Malformation.

BACKGROUND: Fetal cerebral sinovenous thrombosis (CSVT) and dural sinus malformation (DSM) are rare types of fetal cerebral venous pathology that are becoming increasingly recognized as fetal imaging advances. Fetal DSMs are a common source of fetal CSVT, although CSVT may occur without a DSM. The literature on these disorders is limited. METHODS: Cases of fetal CSVT and DSM were identified retrospectively through a query of the Indiana University Health fetal imaging archive from 2007 to 2021. RESULTS: Seven cases were identified, all of whom were alive at birth. A DSM was present in six. Treatments after birth included enoxaparin sodium (3), embolization (3), and shunt placements (1). Five cases had documented regression or complete resolution of the thrombus and/or malformation. One was lost to follow-up, one died from complications of hydrocephalus at nine months, one was receiving physical and occupational therapy at last follow-up at three months, one had concern for autism and mild gait abnormality at 21 months, two had concern for speech delay (18 months and 24 months), and one had normal development at most recent follow-up (four years). CONCLUSIONS: Positive short-term outcomes may occur for some cases of fetal CSVT and DSM. However, risk factors and best treatments are not clear, and long-term outcome data are limited. There is a need for further study.
