The occurrence of post-infarction epilepsy was investigated in 68 patients with angiographically proven internal carotid artery occlusion and in 56 patients with middle cerebral artery occlusion. Epileptic seizures occurred during follow-up in 9% of the carotid artery group and in 21.4% of the middle cerebral artery group. The different incidence of seizures in the two groups was statistically ...

Early spontaneous recanalization of the middle cerebral artery in acute ischemic phase artery is not uncommon, whereas the late spontaneous recanalization of chronic occluded artery is a very rare phenomenon and exact incidence and the timing of this event have not been quantified. We present a case in which late spontaneous recanalization of long-lasting middle cerebral artery occlusion occurr...

and B Sperling, merits attention because it describes the novel application of two non-invasive techniques to address the relationship between vessel dilatation and the pain of headache. Ten migraineurs with unilateral headache were subjected to transcranial doppler sonography (to measure blood velocity within the middle cerebral artery) and single photon emission computerized tomography (to me...

BACKGROUND AND PURPOSE to establish reference values of interhemispheric differences and ratios of blood flow Doppler parameters in the terminal internal carotid artery, middle cerebral artery, and anterior cerebral artery in children with sickle cell anemia. METHODS fifty-seven out of 74 recruited children (mean age, 7.8 ± 3.4 years; range limits, 3-14 years), who were free of neurological d...

BACKGROUND AND PURPOSE Neuroinflammation plays a critical role in the pathogenesis of cerebral ischemia. Triflusal, a selective cyclooxygenase-2, and its active metabolite 3-hydroxy-4-trifluoromethylbenzoic acid may inhibit apoptosis and inflammation after cerebral ischemia. An in vivo model of cerebral ischemia was used to investigate the effects of triflusal and aspirin treatment on infarct v...

PURPOSE OF REVIEW This review will report on the new aspects of management of 'malignant' middle cerebral artery (MCA) infarctions. RECENT FINDINGS Large MCA infarctions have been associated with high death rates for years. The most reliable predictors of a 'malignant' course are hypodensity in more than 50% of the MCA territory on computed tomography as well as stroke volume greater than 145...

Segmentat Middle Cerebral Artery Occlusion in Primates: An Experimental Method Requiring Minimal Surgery and Anesthesia • Due to certain anthropomorphic features of the cerebral circulation, monkeys are generally preferable to lower species in experimental models of stroke. By injecting specially molded silicone cylinders through internal carotid artery cannulas, segmental occlusions of the mid...

We evaluated the efficacy of transcranial Doppler ultrasonography in 23 patients suffering from acute middle cerebral artery occlusion. The diagnosis of occlusion was most suggestive when all basal arteries except the affected middle cerebral artery were detectable. Enhanced blood flow velocity in the anterior cerebral artery due to leptomeningeal collateralization was used as a corroborating c...
