Clinical outcome of patients with internal carotid artery occlusion: A prospective follow-up study

Abstract

ICA occlusion seems to represent a relatively benign condition, in both its symptomatic and asymptomatic presentation. The presence of an atherosclerotic stenosis less than 75% of the contralateral ICA does not seem to worsen the prognosis of this condition.

Benign outcome of objectively proven spontaneous recanalization of internal carotid artery occlusion

“…When initially asymptomatic, ICA occlusion prognosis is usually benign, with a low stroke incidence. [5][6][7] When ICA stenosis progresses to occlusion, the risk of developing an ipsilateral stroke is as high as 25%. 8 As a consequence, 40% to 69% of these patients present a severe residual disability with a 16% to 55% mortality rate.…”

“…On the other hand, once occlusion is established, the subsequent risk of cerebrovascular events seems to be lower (2% to 5% per year), even in initially symptomatic patients. [5][6][7][8]11,12 Color-coded Doppler ultrasound (CCDU) imaging is the first-line noninvasive method for the diagnosis of carotid artery disease, 13,14 featuring a high sensitivity (95%), specificity (100%), and accuracy (97%), even in differentiating a true occlusion from a near-occlusion. 15,16 Traditionally, despite a general complication rate as high as 5% and a stroke risk of 1.0%, the accepted reference test to confirm the presence of ICA stenosis or occlusion was selective contrast angiography.…”

Spontaneous recanalization of internal carotid artery occlusion

“…Th e diagnosis of recanalization of the ICA is not frequent, with no accurate data in the literature about its incidence or most common period of occurrence, since its defi nitive diagnosis is dependent on an invasive examination that is not free from complications [3,4]. According to studies, when spontaneous recanalization of the ICA occurs it is a rather early event, that most commonly happens between 6 hours and 2 weeks [1].…”
