Carotid stump syndrome (CSS) is known to be one of the causes of recurrent ipsilateral ischemic stroke following the occlusion of the internal carotid artery (ICA). The present study describes a case of left CSS in a 50-year-old patient presenting with a central retinal artery embolism following internal carotid and middle cerebral artery occlusion. The central retinal artery embolism was belie...

Technical advances in optical instrumentation have made vascular endoscopy a potential method for intraoperative evaluation of carotid endarterectomy. A prospective protocol was designed to evaluate the efficacy and practicality of this technique using the Hopkins Optical System in 35 carotid endarterectomies. The external carotid artery was examined after completion of the endarterectomy. The ...

Background: With increasing use of invasive diagnostic and interventional procedures in cardio-vascular disease, it is important to fi nd out type and frequencies of vascular variations. Variations in the course, branching and distribution of carotid arteries are commonly encountered. Material & Method: In the present study we have observed variations of the branching pattern of external caroti...

The following matter needs to be addressed. In his seminal works on the circulus arteriosus in Cerebri Anatome in 1664 and De Anima Brutorum in 1672, Thomas Willis described the blood supply to the base of the brain in a number of animal species and, more importantly, founded the discipline of clinical neuroscience. The detailed comparative physiology and species differences between ovine and b...

Background & Aims: Diabetes is a very important factor for stroke due to blocked blood vessels. It can involve systemic and cerebrovascular arteries at the same time via microangiopathy and macroangiopathy. This project aimed to compare the intima-media thickness of carotid artery in children with diabetes type and the control group. Methods: In this case-control study, 50 children with the age...

OBJECTIVE: In animal models of aortic insufficiency, the right common carotid artery is typically used to damage valve leaflets; this strategy impedes subsequent assessments of left ventricular hemodynamics. The present study aimed to establish an alternative technique that would allow subsequent left ventricular catheterization to monitor sequential hemodynamics in rats with aortic insufficien...
