Recent onset neurofibromatosis complicating eclampsia with maternal death: a case report

Neurofibromatosis type 1 and pregnancy complications: a population-based study

OBJECTIVE

The objective of the study was to determine whether vascular and other complications are more common in pregnant women with neurofibromatosis type 1 (NF1).

STUDY DESIGN

We performed a population-based retrospective cohort study using the US Nationwide Inpatient Sample, 1988-2009, defining a cohort of pregnancy-related hospitalizations with an associated diagnosis of NF1 and comparing it with the control group not associated with NF1. Multivariable logistic regression was used to adjust for suspected confounders.

RESULTS

Among 19 million pregnancy-related admissions between 1988 and 2009, we identified 1553 associated with NF1 (prevalence 0.008%). A diagnosis of NF1 in delivering mothers was associated with gestational hypertension (adjusted odds ratio [AOR], 1.6, 95% confidence interval [CI], 1.2-2.0), preeclampsia (AOR, 2.8, 95% CI, 2.3-3.4), intrauterine growth restriction (AOR, 4.6, 95% CI, 3.7-5.6), cerebrovascular disease (OR, 8.1, 95% CI, 2.6-25.4), preterm labor (AOR, 1.6, 95% CI, 1.4-1.9), and cesarean delivery (AOR, 2.0, 95% CI, 1.8-2.3). Women with NF1 were not significantly more likely to have deep venous thrombosis/pulmonary embolism, acute cardiac events, or stillbirth or to die during their hospitalizations compared with the general obstetric population.

CONCLUSION

NF1 was associated with increased maternal morbidity in pregnancy (including hypertensive and cerebrovascular complications) but not increased maternal mortality. Obstetricians should be aware of the potential for increased antenatal and peripartum complications among women with NF1.

Caring for the pregnant woman with neurofibromatosis

Neurofibromatosis (NF) is one of the most common inherited single-gene disorders in humans, and is expressed as two distinct types: Type I (von Recklinghausen disease) and Type II, which occurs much less frequently. When it was first reported in the obstetric literature in 1906 by Brickner, neurofibromatosis was called "fibroma moluscum contagiosum." This article presents a case of a 20-year-old woman with NF Type I who became pregnant. The clinical challenges of NF and pregnancy are explored through the collaborative relationships between the patient and two clinical nurse specialists from obstetric and neuroscience nursing. The case study provides valuable information for nurses who want to provide evidence-based care.

Spontaneous acute subdural haematoma and intracerebral haemorrhage in patient with HELLP syndrome: case report

HELLP (haemolysis, elevated liver enzymes, and low platelet count) syndrome can result in a fatal intracranial haemorrhage during the perinatal period. We report treatment of a 32-year-old primigravida who fell into a deep coma during labour with fetal distress, complicated by a spontaneous acute subdural haematoma and intracerebral haemorrhage. Simultaneous emergency operations, evacuation of the acute subdural haematoma and a caesarean section, were performed, during which a diagnosis of HELLP syndrome with disseminated intravascular coagulation was made. Both mother and infant recovered, though hemiparesis persisted in the mother. Patients with HELLP syndrome should be managed as high-risk, which requires an excellent working relationship of the physicians involved. Prompt recognition of intracranial haemorrhagic complications and neurosurgical intervention are particularly important.

Maternal deaths due to eclampsia and HELLP syndrome

OBJECTIVE

To evaluate maternal deaths associated with eclampsia, HELLP syndrome, and the concurrence of these conditions.

METHOD

A review of Medline studies reporting maternal deaths associated with eclampsia or HELLP syndrome published in English, Spanish, and Portuguese between 1995 and June 2008.

RESULTS

A total of 304 deaths were identified: 100 due to eclampsia, 117 due to eclampsia/HELLP, and 87 associated with HELLP syndrome. Of the total deaths, 71.3% of women had seizures and 67.1% developed HELLP syndrome. In high-income countries 3.9% of deaths were due to eclampsia without HELLP syndrome, while in low-income countries this figure was 42.5% (P<0.0001). The presence of HELLP syndrome in the women who died of eclampsia was 90.6% (29/32) in high-income countries compared with 47.6% (88/185) in low-income countries (P<0.001).

CONCLUSION

Concurrent eclampsia and HELLP syndrome was diagnosed in 5-6 out of 10 deaths associated with eclampsia or HELLP syndrome in this review.
