Ultrasound imaging of carotid web with atherosclerosis plaque: a case report
Abstract
To the best of our knowledge, no previous studies on carotid webs with atherosclerosis plaque have been conducted. Thus, both radiologists and clinicians have insufficient knowledge of this disease, which could lead to misdiagnosis and missed diagnosis. An accurate diagnosis is beneficial to clinical management and prevention of stroke. Here, we present a case of a carotid web with an atherosclerotic plaque, which was confirmed by histopathology and was treated at the Department of Neurosurgery, Beijing Tiantan Hospital. We report a rare case of a carotid web with an atherosclerotic plaque in a 61-year-old Han man. He presented to our hospital with history of intermittent dizziness and slurred speech for 1.5 years and numbness of both upper limbs for 4 months. A computed tomography angiography examination indicated severe stenosis at the beginning of the left internal carotid artery with plaque surface ulceration. Doppler ultrasound examination showed a carotid web with a thin isoechoic plaque and a membrane-like structure protruding into the lumen from the lateral posterior wall at the beginning of the left internal carotid artery. The thin isoechoic plaque could be seen at the base of the membrane-like structure. Carotid endarterectomy was performed to alleviate symptoms. A carotid web with atherosclerosis was diagnosed intraoperatively, and postoperative pathology confirmed extensive intima fibroid hyperplasia accompanied with myxoid degeneration. The base of the carotid…
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
