carotid stenosis/seizures

Cerebral hyperperfusion syndrome after carotid endarterectomy is an uncommon but distressing complication. Findings in nearly all these patients include the presence of ipsilateral high-grade carotid artery stenosis, postoperative ipsilateral headache followed by seizures, and transient neurologic

Glossopharyngeal neuralgia, asystole, and seizures occurred in a patient with an internal carotid occlusion and external carotid stenosis. Swallowing was the triggering mechanism for these events. Mechanical stimulation of the pharynx failed to reproduce the symptoms. An ischemic injury to the

Several studies have investigated the frequency of epileptic seizures following ischemic strokes and transient ischemic attacks (TIAs). Little attention has been paid to the possibility that seizures may be precipitated by TIAs. We examined if seizures can be the only symptom of a TIA and how often

OBJECTIVE To assess the efficacy and safety of percutaneous transluminal stenting for patients with carotid artery stenosis. METHODS Selective percutaneous transluminal stenting was performed for patients with symptomatic carotid artery stenosis (luminal narrowing > or = 70%). Success rates and

BACKGROUND Syncope is commonly worked up for carotid stenosis, but only rarely attributed to it. Considering paucity of such cases in literature, we report a case and discuss the pathophysiology. METHODS We report a patient with high-grade bilateral severe internal carotid artery (ICA) stenosis who

OBJECTIVE The transluminal angioplasty and stenting procedure has been recently advocated as a potential alternative to surgical endarterectomy for the treatment of severe extracranial carotid stenosis. This study assesses the incidence and significance of intracranial hemorrhage occurring after

Limb shaking is a paroxysmal involuntary hyperkinetic movement that may be a presentation of severe unilateral steno-occlusive carotid disease. This unusual form of transient ischemic attack (TIA) is often misdiagnosed as focal motor seizures, especially with frequent repetition. We present a case

Seizures are uncommon after carotid endarterectomy. Patients at greatest risk for having this complication are those with high-grade carotid stenosis and possibly those with recent stroke or severe hypertension. The most favored theory regarding the pathophysiology is hyperperfusion caused by

Cerebral hyperperfusion syndrome as a complication of carotid endarterectomy (CEA) has been widely reported in the surgical literature. It may occur within hours to 3 weeks after CEA and is characterized by symptoms ranging from headaches, fits, confusion, focal neurological signs to intracerebral

Limb shaking (LS) is often confused with focal motor seizures. Distinguishing between both is crucial, because LS may represent an indicator of severe carotid occlusive disease and patients are at high risk of stroke. We report the case of a patient with occlusive carotid stenosis without definite

Cerebral hyperperfusion syndrome (CHS) is a rare life-threatening complication of carotid endarterectomy (CEA) and carotid artery stenting (CAS) for carotid artery stenosis. The incidence varies between 0 and 3%, depending on the severity of the stenosis, perioperative hypertension, and

We studied four patients with focal motor seizures complicating carotid endarterectomy and compared them with 14 other cases reported previously. Seventeen of the 18 patients had high-grade carotid stenoses. A severe unilateral headache usually preceded seizure activity, which was followed by

Three seconds after 0.08 g of Naftidrofuryl administered through the right carotid artery during an operation for carotid stenosis a right temporal sharp wave discharge occurred followed by diffuse polyspike activity occurring every 3to4 seconds with concomitant myoclonus. Rare episodes of this type

Hyperperfusion syndrome (HPS) is a neurological syndrome, which consists of a triad of unilateral headache, seizures and focal neurological deficits. In its extreme form it can present as an intracerebral hemorrhage. Originally HPS was described in patients undergoing carotid endarterectomies for

Correction of high grade carotid artery stenosis may result in cerebral hyperperfusion because of defective vascular autoregulation. Thus, transcranial Doppler was used to determine mean arterial flow velocity (Vmean) of the middle cerebral artery in 95 patients before and after carotid
