“…31 Some authors emphasize that female sex alone is not an adjunctive risk factor for poor outcome after CEA in comparison to male patients, however subgroups of female patients at ahigher surgical risk can be distinguished -with contralateral occlusion or diabetes. 32 The idea that certain medical and angiographic characteristics have potential value in determining the perioperative risk in CEA has been discussed. [5][6][7] The risk factor profiles obtained from the NASCET database included the presence of a hemispheric vs retinal TIA, leftsided procedure, contralateral carotid occlusion, ipsilateral ischemic lesion on CT scans, irregular or ulcerated including all patients, regardless of their sex, showed that those with ischemic heart disease and AHA type VI carotid atherosclerotic plaque are at a higher risk for periprocedural stroke.…”
