Internal carotid artery stenosis: validation of Doppler velocimetric criteria ORIGINAL RESEARCH
نویسندگان
چکیده
Background: Carotid endarterectomy is effective in reducing recurrent stroke in patients with carotid stenosis. Duplex sonography is widely used for diagnosing internal carotid artery (ICA) stenosis. Surgeons often base management decisions solely on this technique. Published velocimetric criteria should be validated in each laboratory. This study aims to validate Doppler velocimetric criteria for different grades of ICA stenosis and evaluate intracranial collateralization circuits.

Introduction: Digital Subtraction Angiography (DSA) is the standard method for detection of carotid artery stenosis. This technique has high radiation dose. With the progress of imaging techniques, noninvasive or minimally invasive methods like the CT angiography, MR angiography and ultrasonography with Doppler or Duplex mode were applicable. This study aimed to evaluate and assesse the results...

This is retrospective double-blind research, which was carried out in Imam Khomeini hospital in order to study the accuracy of color Doppler ultrasonography for detecting the site and grade of stenosis in cervical carotid artery. 40 patients with mean age of 62 years studied with color Doppler before DSA angiography. The most common sites of stenosis were left internal carotid (39.5%) and right...

Background and Objective: Numerical modeling of biological structures would be very helpful tool to analyze hundreds of human body phenomena and also diseases diagnosis. One physiologic phenomenon is blood circulatory system and heart hemodynamic performance that can be simulated by utilizing lumped method. In this study, we can predict hemodynamic behavior of one artery of circulatory system (...

Severe internal carotid artery (ICA) stenosis is a common cause of cerebrovascular accident (CVA) in middle-aged patients. Contralateral carotid occlusion (CCO) in patients with severe ICA stenosis is associated with high risk of CVA. Carotid endarterectomy (CEA) is associated with more complications in patients with CCO than those without CCO. In this study, we present the case of a 61-year-ol...
