Summary:
Ocular symptoms can be the first sign of carotid artery stenosis. In our carotid
endarterectomy patients group were ocular symptoms present in 15%, as the
only sign (without accompanying neurological signs) in 10.5%. Amaurosis fugax
was a dominant sign in 56 cases, blindness in 5, quadrantanopia in 3; trochlear
and oculomotor nerve paresis in one case. Angiography finding of more than
60% ICA stenosis according NASCET criteria was an indication for surgery. The
operative technique per se was a microsurgical endarterectomy with selective
peroperative shunt application. The 30-d morbidity was 3% - with one case of
central retinal artery embolization and subsequent blindness and another case
of major residual neurological deficit due to hyperperfusion syndrome and the
resultant capsular hemorrhage. Shunt was applied in 3% of cases and
microscope was used always since the beginning of the dissection up to the
final suture. Considering low perioperative morbidity/mortality rates the
carotid endarterectomy represents an important means of brain ischaemia
profylaxis. In the process of hemodynamically significant ICA stenosis,
indication for surgical management the authors emphasize the role of
ocular signs and symptoms and thus the importance of an ophthalmology
consultant.
