JAMA Sub-Journal: Be alert!

In 2016, a case-control study published in the journal Neurology showed that in young stroke patients with unknown etiology , there is a statistically significant correlation between the carotid artery network (CW) and ischemic stroke.

Imaging evidence of different CWs in CTA images

"But compared to atherosclerotic plaques, carotid net often because of their seemingly innocuous, is ignored by clinicians.

Subsequently, some studies have shown that symptomatic CW patients have a high risk of recurrence and stroke, but there is a lack of high-quality data.

This comparative cohort study used data from the MR CLEAN trial (2010-2014) and the MR CLEAN registry (2014-2017), the latter two were conducted in the Netherlands on the intravascular large vessel occlusion (LVO) stroke A national prospective multicenter study of treatment (EVT).

Two neuroradiologists evaluated the CTA images to determine if CW is present and identified 30 CW patients with stroke.

An image of the carotid artery network in a patient with cryptogenic stroke: Axial CTA and partial enlarged view (A) show the membrane-like structure in the carotid artery; sagittal CTA (B) shows the intra-arterial sheet-like structure, described with the carotid artery network Unanimous.

Information about some stroke patients

The researchers pointed out that 1 out of 6 symptomatic CW patients had a relapse within 2 years, indicating that medical management alone may not provide adequate protection for CW patients.

In summary, in patients with unexplained stroke, there is a correlation between the carotid artery network and ischemic stroke.
