Malignant Emboli on Transcranial Doppler During Carotid Stenting Predict Postprocedure Diffusion-Weighted Imaging Lesions

Carotid angioplasty and stenting (CAS) has a higher incidence of periprocedural stroke compared with endarterectomy. Identifying CAS steps with the highest likelihood of embolization may have important implications. We evaluated CAS safety by correlating the findings of procedural transcranial Doppler with postprocedure diffusion-weighted imaging (DWI) lesions.
