“…While innominate artery occlusions typically do not result in symptoms of cerebral dysfunction, unless there are numerous atherosclerotic lesions in cerebral arteries or subpar collateral circulation (1,4,5) , they can still pose a risk for arterial insufficiency, which can impact the brain and lead to transient brain ischemia (7) . Although the true incidence of innominate artery occlusion or stenosis remains un-known due to its rare clinical presentation (6) , there have been a few case studies describing this uncommon occurrence.…”

“…Sonographic abnormalities from this study included reversed or bidirectional flow in the right vertebral artery, mid-systolic deceleration in right carotid system branches, and an elevated left common carotid artery (LCCA)/RCCA ratio (5) . Due to there being no standardized guidelines for the treatment and management of innominate artery occlusion or stenosis (7,8) , it is crucial to conduct further research into potential diagnostic and therapeutic interventions to effectively manage innominate artery occlusions and the associated cerebrovascular symptoms (4) . This case study describes a 64-year-old asymptomatic male presenting with a carotid bruit and hypertension.…”

asymptomatic male patient with innominate artery occlusion. Innominate artery occlusion is a rare clinical entity that can lead to a range of cerebrovascular symptoms, including arm claudication, subclavian steal syndrome, and stroke. The case report emphasizes key learning points in diagnosing innominate artery occlusion using imaging and physiological methods. Case description: A 64-year-old asymptomatic male patient with a history of carotid bruit, hypertension, coronary artery bypass grafting, aortic aneurysm, hyperlipidemia, mild aortic stenosis, long-term tobacco use, and a body mass index of 24 was referred for a carotid ultrasound. Conclusions: Innominate artery occlusion is a rare condition requiring a comprehensive assessment of collateralization before any intervention is attempted. Considering waveform features such as transient end-diastolic flow reversal and tardus parvus, along with brachial pressures and transcranial Doppler, can assist in evaluating the extent of disease.
