Role of colour doppler in the evaluation of carotid artery disease in patients of stroke
Journal Title: Medpulse International Journal of Radiology - Year 2018, Vol 8, Issue 3
Abstract
Objective: To study the role of carotid in role of carotid artery stenosis, evaluatrion of plaque and distribution of risk factors between Non-Lacunar and Lacunar subtypes, in patients with stroke. Design: A prospective cross sectional study by single operator using Doppler ultrasound for plaque characterization and to obtain flow velocity wave forms in Carotid vessels. Duration: September 2016 to November 2017. Setting: Department of Radio-diagnosis in association with Department of Medicine, Deccan College of Medical Sciences, Hyderabad. Participants: Seventy patients with positive CT findings of ischemic stroke admitted in DCMS. Methods: Pearson’s chi square-correlation estimation with Y ates correction, Odds ratio, unpaired ‘t’ test were used for the data tabulated from the flow velocity waveforms. Results: Non-Lacunar stroke patients were associated with male sex, smoking, alcohol, highe mean age, higher Carotid IMT(1.1mm), more echolucent plaques(76%) and Carotid artery stenosis(82.5%) compared to Lacunar stroke. In our study diabetes and hypertension did not show any significant difference in association between Lacunar and Non-Lacunar stroke. Conclusion: Presence with presence of risk factors for atherosclerosis, increased IMT and echolucent plaques on carotid Doppler study are at a higher risk for future stroke and must be followed up for progression of atherosclerosis.
