[Carotid endarterectomy in patients with neurological non-side related (NSRS) symptoms].
Out of 970 carotid endarterectomies (CE) performed for high-grade (> 80%) stenosis of the internal carotid artery (ICA) until 1995, 147 patients with neurological non side-related symptoms (NSRS) and without any cardiac, ocular or vestibular significant pathology have been evaluated, analyzing the medium and long-term functional results (mean follow-up 37.6 months) related to the morphological status of the ICA contralateral and the vertebral arteries. NSRS disappeared in 126 pts (85.71%): contralateral ICA was non-stenotic in 32 cases (25.39%), stenotic < 75% in 68 cases (53.96%), stenotic > 75% in 7 cases (5.55%) and occluded in 19 cases (15.09%); vertebral arteries were pathological in only 6 cases (4.75%), among which 4 were on the same side and 2 on the opposite side of CE. NSRS persisted in 20 pts (13.6%): contralateral ICA was non-stenotic in 5 cases (25%), with a stenosis < 75% in 11 cases (55%) and with stenosis > 75% in 4 cases (20%); vertebral obliterative lesions were 3 (15.78%), among which 1 on the same and 2 on the opposite side of CE. No one statistical comparison among the groups of cases obtained on the ground of the status of ICA and vertebral arteries were significant (p always > 0.05 at chi-square analysis). Authors' data confirmed that high grade stenoses of ICA can cause NSRS and that CE--always performed at the aim to prevent major neurological attacks--can relieve also these functional disorders in the most of cases, independently from the status of the contralateral ICA and the vertebral arteries.
