![]() If a further ultrasound scan is required on your head this can take an additional 30 minutes. Significant ICA stenosis on duplex screening in elderly patients with multi-vessel coronary artery disease or certain risk factors may predict post-CABG stroke. Ultrasound (Doppler) scans of your Carotid Artery 3 The procedure should take no longer than 30 minutes, but can vary from patient to patient. Thromboembolism from an unstable atherosclerotic plaque at the carotid bifurcation or the internal carotid artery accounts for 2030 of all ischemic strokes. Its two-dimensional gray scale can be used for measuring the intima. Advancing age, significant ICA stenosis and multi-vessel coronary disease were seen associated with a post-CABG event. Stroke is the 3rd leading cause of death and the most common cause of disability worldwide. Carotid Doppler ultrasonography is a popular tool for evaluating atherosclerosis of the carotid artery. Early sonographic detection and repeat evaluation are necessary to guide clinical management. The risk of ischemic stroke is increased. Post-coronary artery bypass graft neurologic event was seen in 4.5% of patients. Background Carotid artery dissection due to extension of aortic dissection (CAEAD) is a severe complication of acute aortic dissection. One hundred twenty eight patients (72%) were having ICA disease, while significant carotid artery stenosis (>70%) was seen in 11 patients (6.2%). Chi-square test was used to determine association of stenosis degree with post-CABG neurologic event. Post-coronary artery bypass graft neurologic event (namely, transient ischemic attack or stroke) was recorded. Advancing age (65 years or above), gender, smoking, obesity, diabetes (DM), hypertension (HTN), dyslipidemia, coronary vessel disease, cardiac disease and previous stroke were recorded. Patients with combined CABG and cardiac surgery, and those with limited carotid studies were excluded. All Saudi patients (n=178) who underwent duplex carotid sonography prior to CABG were retrospectively reviewed for essential morphologic and hemodynamic information to estimate severity of extra-cranial internal carotid artery (ICA) stenosis. Carotid Doppler ultrasonography is a popular tool for evaluating atherosclerosis of the carotid artery. This descriptive, observational study was conducted in Radiology Department at King Fahad Military Medical Complex, Dhahran, Kingdom of Saudi Arabia from April 2015-2018. To evaluate the use of duplex carotid artery screening in patients undergoing coronary artery bypass graft (CABG).
