- 195 patients with carotid stenosis ≥70% underwent CAS
- Pre-op carotid HR-MRI was done to classify plaques as stable (type VII/VIII) or vulnerable (type IV/V/VI)
- Emboli collected intraoperatively via EPDs were graded (types A-D); types C & D = "large emboli"
- 58 patients had large emboli (Group Y), 137 had small emboli (Group X)
- Logistic regression identified 4 independent risk factors for large embolus shedding: older age, longer stenosis, smoking, and ≥3 prior TIAs
- Vulnerable plaques + more risk factors = progressively higher risk of large emboli (44% with 0 RF → 84.6% with 4 RFs)
- Conclusion: Carotid HR-MRI can predict intraoperative large embolus shedding in CAS
Cerebral infarction (CI) is one of the main causes for the death and disability in elderly individuals, and carotid stenosis is an important risk factor for CI. It has been reported that about 26%–28% of patients with a carotid stenosis degree of 70%– 90% as well as cerebral ischemic symptoms will develop CI within 1 year [1], and carotid stenosis-induced CI accounts for 20% of CI cases [2]. Carotid artery stenting (CAS) and carotid endarterectomy (CEA) are the two main surgical methods used to manage carotid stenosis [3], and CEA has always been considered as the "gold standard" treatment for carotid artery stenosis. However, CAS has progressively become the new technique that is most likely to replace CEA [4,5]. One serious complication in CAS is lesion plaque shedding, resulting in CI [6]. There still exist wide controversies regarding whether applying cerebral protection devices can reduce the occurrence of intra-CAS CI. Some reports indicate that the use of embolic protection devices (EPDs) can effectively reduce the occurrence of embolism complications [6,7], but other reports indicate that the use of EPDs not only effectively reduce, but also increase surgery costs and protection device-induced complications, such as vascular spasm and vascular dissection [8–10]. The most important complication that causes death and disability inCAS is intraoperative embolus shedding-induced vascular embolization [6]. Carotid high-resolution magnetic resonance imaging (HR-MRI) can directly reflect important biological characteristics such as plaque size and composition, as well as the structure of the carotid artery wall. Carotid HR-MRI has unique advantages in evaluating different types of atherosclerotic plaques, especially in evaluating the stability of vulnerable plaques, compared with those of other methods [11]. Whether carotid HR-MRI can be used to assess patients’ carotid plaques to predict the incidence of embolus shedding in advance — thus providing a reliable clinical basis for the necessity of applying EPDs in high-risk patients — remains a question. This study intended to find the risk factors for the occurrence of large emboli combined with carotid HR-MRI to provide clinical judgment of carotid plaque types before CAS, predict the incidence of intraoperative embolus shedding, and provide a basis for the application of EPDs.

- CI as a major cause of death/disability in the elderly
- 26-28% risk of CI within 1 year for 70-90% carotid stenosis with ischemic symptoms
- 20% of all CI cases are carotid stenosis-induced
- CAS vs CEA comparison; intraoperative plaque shedding as the key complication
- Controversy around EPD use (benefit vs added cost/risks)
- What HR-MRI offers (plaque size, composition, wall structure, vulnerable plaque assessment)
- Knowledge gap: Can HR-MRI predict embolus shedding to guide selective EPD use?
- Study aims: identify risk factors, classify plaques pre-CAS, guide EPD application
- Hypothesis statement at the bottom
