Background and Purpose A model for cerebral ischemia that requires injection of emboli into the internal carotid artery of the rabbit is commonly used. However, in our experience we have found the anatomy of the cervical carotid to be highly variable. If not appreciated, this may result in unexpectedly high variability in the severity of ischemic injury. We undertook this experimental protocol ...

 Introduction: Prevalence of stroke following coronary artery bypass graft surgery (CABG) is % 2.1-5.2 and associated with high mortality. The purpose of this study was to investigate the prevalence of carotid artery disease in patients undergoing CABG surgery.  Methods: This cross-sectional study was performed in the years 2010-2011 on 192 patients who underwent open heart surgery (CABG) in...

This report describes our experiences with a patient who developed delayed recurrent retinal and hemispheric ischemia distal to an old internal carotid artery occlusion in the neck. Fundoscopy and sequential cerebral arteriography documented that recurrent ischemic symptoms in this individual were the result of embolic fragments arising from the "stump" of the occluded internal carotid artery a...

background the behcet disease is a multisystemic disease with involvement of vessels. objectives our aim is to evaluate the frequency of carotid artery disease in asymptomatic carotid artery involvement in patients with behcet disease and compare the results with a control group. patients and methods fifty patients with behcet disease who were asymptomatic for any vascular involvement and 50 he...

Posttraumatic external carotid artery pseudoaneurysm with arteriovenous fistula is a rare condition. An 8-year-old child presented with painful pulsatile swelling in the preauricular region following a penetrating glass shrapnel injury. Detailed evaluation showed distal external carotid artery pseudoaneurysm with fistula, which was draining into the retromandibular vein. Endovascular treatment ...

Two main vascular routes supply the brain, internal carotid arteries (ICAs) and vertebral arteries. The external artery (ECA) mainly supplies skin, muscle, skull; thus, neurointerventionalists should be aware of ECA‐ICA, ECA‐vertebral artery, extracranial–intracranial anastomoses. These anastomoses are not newly formed but that remnants developmental processes. During development, ICA has with ...

Internal Carotid Artery Occlusion Diagnosed by Doppler Ultrasound • Using a transcutaneous Doppler ultrasonic blood velocity detector, retrograde ophthalmic artery blood flow was demonstrated in four patients, all of whom had angiographically confirmed occluded internal carotid arteries. In three, compression of the facial artery obliterated the ophthalmic artery signal. In a fourth patient com...
