      Parent Artery Reconstruction for Large or Giant Cerebral Aneurysms Using the Tubridge Flow Diverter: A Multicenter, Randomized, Controlled Clinical Trial (PARAT)

      This was a prospective, multicenter, randomized trial conducted at 12 hospitals throughout China. Enrolled adults with unruptured large/giant intracranial aneurysms were randomly assigned (1:1) to receive either Enterprise stent-assisted coiling or Tubridge flow diverter implantation. The primary end point was complete occlusion at 6-month follow-up, while secondary end points included technical success, mortality, target vessel–related stroke, aneurysm bleeding, in-stent stenosis, parent artery occlusion, and the frequency of all adverse events. The results of 6-month follow-up imaging included complete occlusion rates of 75.34% versus 24.53% for the Tubridge and stent-assisted coiling groups, respectively. This trial showed a higher rate of large and giant aneurysm obliteration with the Tubridgeflow diverter over Enterprise stent-assisted coiling. However, this higher obliteration rate came at the cost of a nonsignificantly higher rate of complications.

      Brain MRI Characteristics of Patients with Anti-N-Methyl-D-Aspartate Receptor Encephalitis and Their Associations with 2-Year Clinical Outcome

      The authors enrolled 53 patients with anti-N-methyl-D-aspartate receptor encephalitis and performed 2-year follow-up. Brain MRIs were acquired for all patients at the onset phase. The brain MR imaging manifestations were classified into 4 types—type 1: normal MR imaging findings; type 2: only hippocampal lesions; type 3: lesions not involving the hippocampus; and type 4: lesions inboth the hippocampus and other brain areas. Twenty-eight (28/53, 53%) patients had normal MR imaging findings (type 1), and the others (25/53, 47%) had abnormal MRI findings—type 2: 7 patients (13%); type 3: 7 patients (13%); and type 4: 11 patients (21%). The presence of hippocampal lesions and relapse was associated with poor outcome.

      Localized Marked Elongation of the Distal Internal Carotid Artery with or without PHACE Syndrome: Segmental Dolichoectasia of the Distal Internal Carotid Artery
      Z.Y. Jia, L.B. Zhao and D.H. Lee
      American Journal of Neuroradiology May 2018, 39 (5) 817-823; DOI: https://doi.org/10.3174/ajnr.A5573

      Intracranial dolichoectasia of the distal ICA was identified in 20 patients from 2005–2016 through a review of diagnostic cerebral angiography results. Images were reviewed to determine the vascular morphologic dispositions around the distal ICA, including dysplasia, mural calcification, vessel wall enhancement, lumen narrowing, and aneurysm formation. In this cohort, which had a strong female predominance (male/female ratio2:18), intracranial dolichoectasia had a more ipsilateral vascular morphologic disposition. Mural calcification was detected more frequently in elderly patients, whereas vessel wall enhancement was detected more frequently in younger patients. Follow-up images showed a slow progression of the lesions. The segmental nature of the striking elongation and tortuosity of the distal ICA suggest a type of congenital lesion representing either a sporadic phenomenon or an arterial change associated with PHACE syndrome.
