Abstract
The study sought to examine how symptomatic and asymptomatic carotid near-occlusion appeared on angiography. Methods: A blinded study evaluated 635 patients for consecutive CTAs at NRI Medical College/Hospital from June 2021 to May 2022 for estimation of symptomatic and asymptomatic carotid near occlusion. Results: 380 (60%) of the 635 patients (50% carotid stenosis) were symptomatic. Both symptomatic (112, 30%) and asymptomatic (50, 25%) cases of near-occlusion shared the same prevalence. Between symptomatic and asymptomatic cases with near-occlusion, the angiographic appearance was remarkably similar: the mean stenosis lumen diameter (0.7 mm), distal ICA diameter (2.1 mm), and ECA ratio (0.79) were the same in both groups. The average ICA ratio (0.46 and 0.48) and fraction of full collapse (46% and 40%) were fairly similar. Conclusion: The primary conclusion of this study was that there was no change in the angiographic appearance of near-occlusions between symptomatic patients and asymptomatic individuals.
