Amniotic fluid embolism: despite progress, challenges remain.

Purpose Of Review: This article reviews the incidence, pathophysiology, risk factors, diagnosis, and management of amniotic fluid embolism (AFE).

Recent Findings: AFE is a leading cause of maternal morbidity and mortality despite an incidence of approximately 7 to 8 per 100,000 births. Recent reevaluation of AFE suggests that the presence of fetal tissue in maternal circulation alone is not sufficient to cause the clinical syndrome, but rather an individual's response to this fetal tissue.

Selective computed tomographic angiography in traumatic subarachnoid hemorrhage: a pilot study.

Background: Computed tomographic angiography (CTA) tends to be overused in patients with traumatic subarachnoid hemorrhage (tSAH) to rule out intracranial aneurysmal disease. We hypothesized that there are two exclusive subsets of patients with tSAH that maybe at increased risk for aneurysm and thus should undergo CTA, those "found down" with an unknown mechanism of injury and those with "central subarachnoid hemorrhage" (CSH, in the subarachnoid cisterns and Sylvian fissures). This pilot study was performed to provide more information on the validity of our hypothesis.
