Neuroform Atlas (NFA; Stryker Neurovascular, Fremont, CA, USA) is a useful and safe device for the treatment of broad-necked and unruptured cerebral aneurysms. Rarely does a proximal shift of both the stent and delivery catheter occur during deployment, and it can be complex to treat. We present two cases in which an NFA that had migrated proximally during deployment was successfully retrieved.

- The study aimed to investigate subclinical cognitive damage after surgical clipping (SC) and endovascular coiling (EC) for unruptured cerebral aneurysms, using cerebral blood flow (CBF) measurements as an indicator of potential issues not detected by standard cognitive tests.
- Participants included 14 patients in the SC group and 33 in the EC group, with assessments conducted preoperatively, at 6 months, and 2 years post-surgery, revealing no significant changes in cognitive function over time.
- Results showed a notable decrease in ipsilateral CBF in the SC group, which did not recover within 2 years, while CBF levels in the EC group returned to normal,
Article Synopsis
- * A case was reported of a woman in her 70s who experienced an unusual migration of the WEB device 12 days post-surgery, leading to the occlusion of her internal carotid artery.
- * Traditional retrieval methods failed, but suction from a Sofia catheter successfully repositioned the trapped WEB, highlighting the need for awareness of delayed migration risks associated with this device.
Background: A flow redirection endoluminal device (FRED) is a widely used flow diverter stent. Although high technical success and good treatment results were reported in the SAFE study, cases of technical failure of deployment have also been reported. A case in which a FRED was deployed with the proximal part twisted, but successful deployment was achieved, is presented.

- - Heart failure can reduce blood flow to the brain, potentially affecting recovery after mechanical thrombectomy (MT) in stroke patients, and this study examined the relationship between brain natriuretic peptide (BNP) levels and recovery outcomes.
- - Data from 169 stroke patients showed that those with favorable outcomes (score of 0-2 on the modified Rankin scale at 3 months) had lower median BNP levels compared to those with unfavorable outcomes, suggesting that higher BNP levels are linked to poorer recovery.
- - The analysis indicated that patients with BNP levels above 186 pg/mL had a significantly lower rate of favorable outcomes, even when considering other factors like atrial fibrillation, reinforcing the idea that high BNP concentration correlates with
