Pdf Summary

This study aimed to evaluate the contribution of Doppler ultrasound of the supra-aortic trunks in the etiological evaluation of ischemic stroke. The study included 271 patients with ischemic stroke who underwent Doppler ultrasound. The results showed that atherosclerotic carotid plaques were found in 76% of the patients, with grade I, II, and III plaques being the most common. Age, female gender, and increased LDL cholesterol were significantly associated with carotid atherosclerosis. The prevalence of carotid stenosis was 5.9%, with age above 70 years being significantly associated with stenosis. The study highlights the importance of Doppler ultrasound in the diagnosis and care of patients with ischemic stroke, showing a high prevalence of carotid plaques and stenosis among these patients. Age, dyslipidemia, and female gender were identified as risk factors for carotid atherosclerosis, while age 70 years was associated with carotid stenosis. These findings emphasize the need for early identification and management of carotid atherosclerosis to prevent stroke. Doppler ultrasound of the supra-aortic trunks can serve as a valuable tool in the assessment of patients at risk for ischemic stroke.
