- Development of Collateral Vessels after Anterior Circulation Large Vessel Occlusion in Pediatric Arterial Ischemic Stroke Relates to Stroke Etiology: A Longitudinal Study
In this single-center retrospective study of pediatric patients with acute AIS related to anterior circulation proximal LVO, a specific pattern of unilateral poststroke anastomotic bridge with collaterals bypassing the affected zone was observed in the first year after stroke. This clinical-radiologic pattern was not associated with stroke recurrence or arterial worsening but was strongly associated with focal cerebral arteriopathy.
- Delayed Enhancement of Intracranial Atherosclerotic Plaque Can Better Differentiate Culprit Lesions: A Multiphase Contrast-Enhanced Vessel Wall MRI Study
This study found that a 9-minute delay in postcontrast acquisition on multiphase contrast-enhanced VW MRI proved to be beneficial for enhancing plaque visibility and for the differentiation between culprit and nonculprit plaques. Additionally, the study showed that culprit and nonculprit plaques exhibit unique enhancement patterns over time.
