Medical management alone remains suboptimal for secondary prevention, and randomized controlled trials failed to demonstrate the efficacy and safety of extracranial‐intracranial vascular bypass. Carotid occlusion endovascular surgery (COES) is a promising technique, yet its efficacy and safety remain unclear. This systematic review and meta‐analysis included studies in which patients with chronic symptomatic internal carotid artery occlusion underwent treatment with COES and medical management. Primary outcomes included successful reperfusion rates and periprocedural ischemic and hemorrhagic events rates. Secondary outcomes included rates of ischemic events recurrence, other periprocedural events, and mortality. Studies contained at least one of the treatment groups and outcomes of interest. Twenty‐two studies were selected for systematic review, with 18 of them for meta‐analysis. From 14 studies (N=561) the rate of successful recanalization was achieved in 74% of all patients undergoing COES. Thirteen studies (N=534) showed that the rate of COES was 2% both for periprocedural ischemic and hemorrhagic events. At long‐term follow‐up, the COES cohort included a total of 10 studies (N=311) and had a 12% rate of ischemic events, while the medical management group, which included 5 studies (N=313), showed a rate of 19%, with nonsignificant subgroup differences ( P =0.09, I 2 , 12%). Rates of other periprocedural mortality were 4% and 1%, respectively.

We aimed to externally validate 4 preidentified imaging biomarkers of ICAS‐LVO: absent hyperdense sign, Hounsfield units (Hu ratio ≤1.1 and Delta Hu <6) and truncal‐type occlusion, observed on admission noncontrast computed tomography and computed tomography angiography in patients presenting with emergent large‐vessel occlusion (ELVO).\u0000 \u0000 \u0000 \u0000 We conducted a retrospective cohort observational study of consecutive patients presenting with acute M1/terminal internal carotid artery occlusions undergoing mechanical thrombectomy.

We used high‐resolution vessel wall imaging to evaluate changes in plaque morphologic pattern and enhancement after treatment with high‐intensity statins.\u0000 \u0000 \u0000 \u0000 Patients with a history of stroke or transient ischemic attack attributable to intracranial atherosclerotic disease underwent 7‐T high‐resolution vessel wall imaging. T1 and T1+gadolinium sequences were obtained at baseline. Follow‐up images were acquired at a minimum of 6 months after the initial scan. Low‐density lipoprotein levels were also recorded at baseline and at follow‐up, after maximal medical therapy was started. Plaque burden, degree of stenosis, and area degree of stenosis were calculated at baseline and follow‐up. Gadolinium enhancement was quantified using a 3‐dimensional pipeline for plaque analysis.\u0000 \u0000 \u0000 \u0000 \u0000 Five patients were included. The mean age was 56 years, and the average time to follow‐up imaging was 17.7 months. Low‐density lipoprotein decreased from a mean of 122 to 111 mg/dL at follow‐up. Plaque burden decreased from μ=76% to 60%, area degree of stenosis decreased from μ=61% to 56%, and gadolinium uptake decreased from a mean of μ=4.11 to 3.76. Furthermore, a lower low‐density lipoprotein at follow‐up was correlated with decreased plaque burden (\u0000 r\u0000 =0.86), lower area degree of stenosis (\u0000 r\u0000 =0.8), and less gadolinium uptake (\u0000 r\u0000 =0.82).\u0000 \u0000 \u0000 \u0000 \u0000 Plaque morphologic pattern and gadolinium uptake changed at follow‐up with high‐intensity statin therapy.
