New surgery to prevent stroke means less operating time and recovery - YouTube

Didn't your doctor tell you of these possible complications?

Possible problems:

Cognitive Dysfunction and Mortality After Carotid Endarterectomy

Carotid Interventions for Women: The Hazards and Benefits

Female Gender Increases Risk of Stroke and Readmission after CEA(Carotid endarterectomy) and CAS(carotid artery stenting)

Ticagrelor Induced Angioedema Following Carotid Artery Stenting

Cognitive Dysfunction and Mortality After Carotid Endarterectomy
