To identify the prevalence and characteristics of aortic atherosclerotic plaque disease and its association with cerebrovascular risk factors in patients with cerebral ischemic events. ⋯ One third of TAA plaques are severe and complex in nature and more frequently present in the descending aorta and the arch of the aorta than in the ascending aorta. TEE should be considered for the early detection and treatment of TAA in patients without identified causes of stroke.

Stroke-like symptoms can be associated with the invasive evaluation and surgical resection of epileptic foci in patients with intractable epilepsy. Neurological deficits following surgical procedures for epilepsy are not uncommon, but most are relatively minor and transient. The authors investigated the neuroimaging patterns of cerebral tissue insults in patients suffering neurological deficits directly related to procedures performed to evaluate and treat intractable epilepsy. They attempted to discern potential secondary vascular insults from the not unexpected tissue loss that can be associated with various epilepsy procedures. ⋯ It is important to distinguish the not unexpected neurological deficits associated with inadvertent trauma to normal brain tissue during procedures associated with epilepsy surgery from vascular insults. Postoperative neuroimaging can be useful in this endeavor.
