Magnesium sul ate was administered and blood pressure lowered with labetalol. A ter a ew days in neurointensive care, the patient improved signi cantly in terms o both her mental status and vision, and repeat vascular imaging a ter 6 weeks demonstrated resolution o the vasospasm, con rming the diagnosis o rcvs (figure 4-5). 38 ch a pt er 4 follow-up ▲ figure 4-5 top panel (patient 1) shows t2-weighted uid-attenuated inversion recovery mr images. High signal is notable predominantly in the subcortical white matter consistent with vasogenic edema with a posterior predominance, consistent with posterior reversible encephalopathy syndrome (pres). Bottom panel (patient 2) shows a normal ct head, initially obtained to rule out subarachnoid hemorrhage. Mr angiogram demonstrated smooth narrowing o multiple intracranial arteries, which spontaneously resolved on ollow-up angiography. The patient ul lled the proposed diagnostic criteria or reversible cerebral vasoconstriction syndrome (rcvs). Used with permission from dr. Daniel mandell, university health network, university of toronto, toronto, ontario, canada. Neuro-ophthalmological vascular events t e increase in cerebrovascular risk in pregnancy may lead to retinal vascular events, including central and branch retinal arterial occlusions, or which a stroke workup should be completed.22 spontaneous orbital hemorrhage, presenting with diplopia, proptosis, and orbital pain, may occur in the rst trimester, in women with severe nausea and vomiting, or during labor a er repeated valsalva maneuvers.22 one must consider the possibility o carotid-cavernous f stula in the di erential diagnosis, or which orbital vascular imaging is indicated, along with other nonvascular causes such as orbital pseudotumor and thyroid ophthalmopathy.21,22 during pregnancy, the pituitary undergoes anatomical and physiological changes leading to an increase in size and resulting predisposition to pituitary apoplexy (sheehan syndrome). Mechanisms include hypotension (to which the pituitary is sensitive due to its vascular supply), malignant hypertension (leading to hemorrhage), stimulation o the enlarged pituitary rom endogenous steroid production in the context o systemic stresses, and bleeding diathesis (endogenous or iatrogenic).21 t e clinical presentation typically includes thunderclap headache, altered mental status, hypotension, and visual symptoms, o which the most pathognomonic would be bitemporal hemianopia but may also include diplopia rom the neighboring cavernous sinus. Di erential diagnosis includes lymphocytic hypophysitis. Primary endocrine presentations such as women’s issues in h ospit a l neur ology polyuria secondary to diabetes insipidus, hypotension due to lack o adrenocorticotropic hormone, postpartum amenorrhea, and inability to lactate are less likely to come to the neurologist’s attention but should be elicited. Optic chiasm or optic nerve compression requires urgent neurosurgical consultation, and endocrinology consultation should be obtained or urgent endocrine replacement therapy. Acute stroke treatment considerations pregnancy was an exclusion criteria in the clinical trials validating recombinant human tissue plasminogen activator (rt-pa) as an acute therapy or stroke. There ore, most in ormation regarding its use stems rom case reports and case series. Given its large molecular size, rt-pa does not cross the placenta, but theoretical concerns regarding etal adverse events exist given the possibility o placental abruption and premature labor. Due to animal studies showing tumorigenicity in rodents and embryocidal e ects when given in high dosages to mothers, rt-pa remains fda category c.23 one large study showed an 8.1% rate o maternal hemorrhagic complications with use o thrombolytics, most commonly uterine bleeding, with the primary concern being or placental abruptio and etal loss. O note, streptokinase was the most common thrombolytic used, there was requent concurrent anticoagulation with heparin, and stroke was only the indication in one o 166 cases, there ore making extrapolations to use o rt-pa in ischemic stroke challenging.24 since then, 11 women have been reported in the literature to have received iv or ia rt-pa while pregnant or ischemic stroke, with one death not thought to be directly related to systemic tpa.16 it has been argued that rt-pa should be o ered on a case-by-case basis, keeping in mind etiologies o stroke in pregnancy that would not respond to rt-pa such as preeclampsia and amniotic uid embolism.25 secondary stroke prevention considerations – anticoagulation, anti-hypertensive medications t e two main therapeutic categories to keep mind ul o in secondary stroke prevention in pregnancy are antihypertensives and anticoagulants.

Experimental work has shown that certain cytokines, such as interferon-'y, have a cytotoxic effect on immature oligodendrocytes (82). However, cytokines may also be secreted in the setting of hypoxia-ischemia (in the absence of infection). Moreover, infection and/or cytokines may lead to ischemiareperfusion, which may cause further injury to oligodendrocytes {83). Thus, there are multiple pathways by which infection/inflammation might cause or contribute to the pathogenesis of pvl. In most cases, the pathogenesis of pvl probably involves a complex interaction of more than one of the pathogenetic mechanisms described above. B. Clinical presentation and diagnosis. Pvl is typically a clinically silent lesion, evolving over days to weeks with few or no outward neurologic signs until weeks to months later when spasticity is first detected, or at an even later age when children present with cognitive difficulties in school. With moderate to severe pvl, some evidence of spasticity in the lower extremities may be detected by the careful observer by term age or earlier. However, pvl is usually diagnosed in neurologic disorders i 705 the neonatal period by cus, or less commonly by mri (84). The evolution of echogenicity in the periventricular white matter over the first few weeks after birth, with or without echolucent cysts, is the classical description ofpvl by us imaging. Ventriculomegaly due to volume loss from atrophy of the periventricular white matter is often present within weeks. Isolated ventriculomegaly is associated with an increased risk of cp (53), suggesting that ventriculomegaly without radiologically evident white matter abnormalities may also indicate the presence ofpvl. Studies corrdating us and autopsy data have demonstrated that the incidence of pvl is underestimated by cus, the technique most widdy used to diagnose brain abnormalities in the preterm infant (85,86). Several studies have shown that mri is more sensitive than cus for the detection of pvl, especially for the noncystic form of pvl (84,87,88). Noncystic wmi detected by mri in the newborn period is evident as high-signal intensity in the cerebral white matter by t2w mri and low-signal intensity by tl w sequences. As for cus studies, there is no universally accepted measure of the severity or extent of signal abnormality by mri that defines wmi. While it is clear that greater severity ofwmi is correlated with a higher incidence oflater neurodevelopmental deficits, there is a broad range of outcomes for mild, moderate, and severe wmi (57), and the threshold for defining clinically significant wmi has not been determined. For example, one study reported abnormal signal intensity within the white matter by mri exam at term age in 80% of infants born at 23 to 30 weeks' ga (89). It has not been shown that this diffuse excessive high-signal intensity on t2-weighted mri correlates with neuropathologically proven pvl, although there was some correlation between this mri finding and mild developmental delay at 18 months of age (89). The routine use ofmri scans to detect wmi or other lesions has not been recommended (3), although it may be useful in some high-risk premature infants. It is probably most useful to perform an mri scan close to term age, if an mri scan is to be obtained during the newborn period. A brain mri is the most useful imaging modality to confirm clinically suspected wmi in an older infant or child born prematurely who presents with cognitive, motor and/or sensory impairments. In older infants and children, the brain mri may show one or more of the following findings. Abnormal signal and/ or decreased volume of the periventricular white matter, a thin corpus callosum, enlarged ventricles with a square appearance to the frontal horns, and/or enlarged extra-axial csf spaces (90). C. Management. There are currently no medications or treatments available for the specific treatment ofpvl during the newborn period. Current efforts are directed at prevention, based on knowledge of the various risk factors and pathogenetic mechanisms described above.
