Patients undergoing carotid endarterectomy in the Department of Vascular Surgery at Oslo University Hospital are consecutively included in this evaluation og pre- and postoperative brain MRI.
Patients undergoing surgery for carotid stenosis in our Department are examined by brain MRI before and after carotid surgery to evaluate the rationale for the MRI. Brain lesions on MRI before and after carotid surgery are registered, and related to clinical findings. The purpose of the study is to evaluate whether brain MRI in relation to carotid endarterectomy gives additional information to clinical findings, and to CT scan of the brain.

| Brain MRI | Diagnostic Test | Brain MRI diagnoses tromboembolic lesions or bleeding to the cerebrum and is part of preoperative diagnostic tests before carotid surgery. After surgery brain MRI may present New lesions related to surgery, clinically significant or insignificant. Our goal is to evaluate the relevance of this modality in carotid surgery.. |
