Congenital absence of an internal carotid artery is a rare anomaly. Less than 1 00 cases have been reported in the English literature. It is usually associated with collateral flow to the involved vascular territory, so neurologic deficits are few. However, this anomaly is also associated with a high occurrence of intracranial aneurysms. We report two cases of absent internal carotid artery wit...

Bilateral pharyngeal internal carotid artery aberration is a rarely seen variation which poses a risk during the surgical interventions of this area. A 74-year-old male patient was admitted to our clinic with the complaints of a sensation of fullness in his throat and dysphagia. Oropharyngeal examination revealed bilateral smooth-surfaced masses in the posterior pharyngeal wall. Magnetic resona...

FIG. 1 T2W Coronal Section of Magnetic Resonance Angiography (MRA) Brain showing a flow void in the left internal carotid artery (arrow). The left internal carotid artery appears dilated and ectatic suggestive of fusiform aneurysm of left internal carotid artery. Fusiform dilatation of vessels of circle of Willis to form large aneurysms, termed “Cerebral Aneurysmal Childhood Arteriopathy”, is a...

BACKGROUND The aim of the present study was to determine the respective influences of local pulse pressure and mean blood pressure on arterial remodeling in humans at 2 arterial sites: a central, predominantly elastic artery (the common carotid artery) and a peripheral muscular artery (the radial artery). METHODS AND RESULTS Forty-three healthy subjects and 124 never-treated hypertensive pati...

The purpose of this study was to analyze the suitability of the cerebral vasculature of the pig regarding a revascularization procedure. In two 60 kg pigs the femoral artery was exposed and canulated for selective angiography and interventional procedures. After the angiography, the pigs were brought to the animal OR for craniotomy and analysis of the intracranial cerebral arteries and the surg...

BACKGROUND AND PURPOSE The purpose of this study was to prospectively investigate the contribution of the ipsilateral external carotid artery (ECA) to cerebral perfusion in patients with internal carotid artery occlusion. METHODS Institutional Review Board approval and informed consent were obtained. Thirty functionally independent patients (24 men, 6 women; mean age, 63 years) with an angiog...

A72-year-old manpresented with paroxysmal and transient involuntary movements, or "limb shaking". The attacks occurred alternately from one side of the body to the other and ceased spontaneously. Surface EMG study showed synchronous grouping discharges in multiple limb muscles, being compatible with hemiballism-hemichorea. Cerebral angiography demonstrated marked stenosis of the bilateral inter...

Epistaxis is commonly encountered in otorhinolaryngologic practice. However, severe and recurrent epistaxis is rarely seen, especially that originating from a pseudoaneurysm of the intracavernous internal carotid artery (ICA). We herein present the case of a 32-year-old man who was involved in a motor vehicle accident and subsequently developed recurrent episodes of profuse epistaxis for the ne...
