Analysis of diagnosis and treatment for acute thromboembolism occlusion caused by severe internal carotid artery stenosis: A case report / 中国脑血管病杂志

ABSTRACT

Ultrasonography revealed that a ease of acute internal carotid artery (ICA) occlusion caused by acute thrombosis due to severe stenosis and intraplaque hemorrhage. The patient is male and 81 years old with blurred vision in the right eye. Carotid artery ultrasound ( CDU) showed that severe stenosis of right proximal ICA, the discontinuous fibrous cap at the top of atherosclerotic plaques, and intraplaque hemorrhage. Besides, the blood flow of the right distal ICA disappeared suddenly during the examination. Therefore, ICA occlusion caused by acute thrombosis was detected by CDU. The patient was followed-up day by day using ultrasonography and treated with dual antiplatelet therapy. Three days later, CDU showed that the right ICA was re-open but still accompanied by severe stenosis. The patient was treated by carotid endarterectomy for revascularization after six days of admission. According to this process of diagnosis and treatment, carotid ultrasound provides an important clinical role for the diagnosis, treatment, and follow-up of acute thrombosis with carotid artery stenosis.
