Pre-operative and post-surgical symptoms like transient ischemic attacks, strokes, headaches, and amaurosis fugax
were evaluated; however, the study focused on the incidence of carotid artery restenosis based on Duplex studies and confirmed by angiography.
Ten patients were asymptomatic, one had amaurosis fugax
, four had transient ischemic attack within last four months, one had drop attacks, one had headache, seven had the findings of hemiparesis and three had hemiplegia.
Prompt identification and appropriate treatment of amaurosis fugax
can result in maintenance of normal vision.
All had experienced a hemispheric transient ischemic attack (TIA), amaurosis fugax
(blindness of one eye, often like a shade pulled down over it) lasting less than 24 hours, or a nondisabling stroke within the previous 4 months.
History of stroke: The major source of controversy in assessing the history of stroke is whether transient ischaemic attacks (TIA) (31/24/0) or amaurosis fugax
(22/32/0) should be considered as strokes.
The patient usually presents with sudden painless loss of vision, with prior history of amaurosis fugax
ranging from few minutes to few hours may be present.

Estan presentes en el 70% de los casos y pueden comprometer cualquier territorio, presentandose como amaurosis fugax
, sintomas motores o sensitivos, afasias o deficits de campo visual.
However, in the setting of evolving vision loss or amaurosis fugax
, intravenous methylprednisolone, 500 mg to 1 g daily for 3 days followed by oral prednisone, should be used.
Valvular vegetations can release emboli and lead to episodes of amaurosis fugax
or retinal artery occlusion (2).
The reasons for examination were varied: 42% had symptoms of transient ischemic attacks, 36% had symptoms of stroke, and 22% had symptoms of amaurosis fugax
When the blood supply from the carotid arteries is compromised, common clinical manifestations include contralateral focal motor and sensory interruptions and amaurosis fugax
(transient monocular blindness).
For amaurosis fugax
, the risk is 17% at 2 years versus 43% for transient hemispheric attacks.
