Controlled Clinical Trial
Arterial blood gas analysis of samples directly obtained beyond cerebral arterial occlusion during endovascular procedures predicts clinical outcome.
Real-time intra-procedure information about ischemic brain damage degree may help physicians in taking decisions about pursuing or not recanalization efforts. ⋯ Direct local blood sampling from ischemic brain is feasible during endovascular procedures in acute stroke patients. A gradient in oxygenation parameters was demonstrated between pre- and post-occlusion blood samples. ABG information may be used to predict clinical outcome and help in decision making in the angio-suite.

In this study, we sought to determine whether routine head computed tomographies (CTs) after uncomplicated coil embolization of intracranial aneurysms can add any significant clinical value. ⋯ A head CT after uncomplicated coil embolization of an intracranial aneurysm does not add any significant clinical value and should not be ordered routinely.

Isolated focal common carotid artery dissection is a rare condition. ⋯ Focal isolated common carotid artery dissection is a rare condition not to be overlooked. This case presents an incidental finding possibly of traumatic nature. In the presence of concomitant migraine its causal embolic relation to the transient word-finding difficulties must remain open.

Hepatic encephalopathy (HE) is an uncommon complication of total parenteral nutrition (TPN). Cytotoxic edema has not been reported in children with TPN-related HE. We describe a case of TPN-related HE presenting with diffuse cytotoxic edema which reversed after liver transplantation.

Noncontrast computed tomography (NCCT) has been considered the standard test for determining eligibility for thrombolysis from the beginning of the thrombolytic era. CT angiography (CTA) reveals the cranio-cervical vessel and the occlusion site. Furthermore, the source image (SI) of the CTA (CTA-SI) reflects cerebral blood volume and can detect the infarct core as hypoattenuated areas with higher sensitivity than ischemic changes on NCCT. ⋯ On the other hand, CTA-SI using standardized protocol was reported to be good predictor for final infarct extension. Imaging used in the setting of acute stroke should accurately address the presence and size of an irreversible ischemic core. Further studies are required to confirm whether another measure or adjustment in CTA-SI values can be more reliable for evaluating the infarct core.
