Review Meta Analysis
Silent Brain Infarction and Risk of Future Stroke: A Systematic Review and Meta-Analysis.
Silent brain infarction (SBI) on magnetic resonance imaging has been proposed as a subclinical risk marker for future symptomatic stroke. We performed a systematic review and meta-analysis to summarize the association between magnetic resonance imaging-defined SBI and future stroke risk. ⋯ SBI is present in ≈1 in 5 stroke-free older adults and is associated with a 2-fold increased risk of future stroke. Future studies of in-depth stroke risk evaluations and intensive prevention measures are warranted in patients with clinically unrecognized radiologically evident brain infarctions.

Pregnancy and puerperium are associated with an increased risk of venous thrombotic events (VTEs), including cerebral venous thrombosis (CVT). We aimed to systematically review, in pregnant woman with previous CVT, (1) the risk of recurrence of CVT or other VTE; (2) the result of pregnancy; and (3) the association of antithrombotic prophylaxis with these outcomes. ⋯ In women with previous CVT, the absolute risk of pregnancy-related venous thrombosis is low but the relative risk of noncerebral VTE is 16-fold higher and the recurrence of CVT is 80-fold higher than the baseline risk described in general population studies. The rate of miscarriage is not significantly different from that estimated for the general population.

Review Case Reports
Posterior Reversible Encephalopathy Syndrome as an Overlooked Complication of Induced Hypertension for Cerebral Vasospasm: Systematic Review and Illustrative Case.
Delayed cerebral ischemia associated with cerebral vasospasm is a common cause of secondary neurological decline after aneurysmal subarachnoid hemorrhage (SAH). Triple-H therapy, induced hypertension, hypervolemia, and hemodilution, is often used to treat cerebral vasospasm. However, hypertensive treatment may carry significant medical morbidity, including cardiopulmonary, renal, and intracranial complications. Posterior reversible encephalopathy syndrome (PRES) is a reversible intracranial complication that has rarely been reported in the setting of induced hypertension. ⋯ PRES in the setting of SAH is an overlooked complication of hypertensive therapy for the treatment of vasospasm. However, the diagnosis of this phenomenon is crucial given the necessity to reverse hypertensive therapy, which is contrary to the usual management of patients with vasospasm.
