Commentary Cerebral hyperperfusion syndrome following carotid endarterectomy
Extracranial internal carotid artery stenosis accounts for 15–20% of ischaemic strokes and carotid endarterectomy (CEA) is the most frequently performed surgical intervention in stroke prevention. The risk of stroke and death associated with the operation has been estimated at about 5.6% (95%CI 4.4–6.9). Neurological complications following CEA are usually ischaemic in nature, due to embolizati...
متن کاملCerebral hyperperfusion syndrome occurring three weeks after carotid endarterectomy.
Cerebral hyperperfusion syndrome is a recognized complication of carotid endarterectomy. Various studies have documented an incidence of 0.3 to 1.2%. It occurs in the setting of sudden reperfusion of a chronically hypoperfused hemisphere. We present here a case of a 48-year-old lady who developed cerebral hyperperfusion syndrome three weeks after undergoing a carotid endarterectomy for high-gra...
متن کاملNear-infrared spectroscopy can predict the onset of cerebral hyperperfusion syndrome after carotid endarterectomy.
BACKGROUND Cerebral hyperperfusion syndrome (CHS) after carotid endarterectomy (CEA) is a potential life-threatening complication. Therefore, early identification and treatment of patients at risk is essential. CHS can be predicted by a doubling of postoperative transcranial Doppler (TCD)-derived mean middle cerebral artery blood velocity (V(mean)) compared to preoperative values. However, in a...
متن کاملRegarding "Cerebral hyperperfusion syndrome after carotid endarterectomy: predictive factors and hemodynamic changes".
PURPOSE It is believed that cerebral hyperperfusion syndrome (CHS) is caused by loss of cerebral autoregulation resulting from chronic cerebral ischemia and that factors including increased intraoperative cerebral blood flow, ipsilateral or contralateral carotid disease, and postoperative hypertension may cause CHS. We describe our experience with CHS, which diverges from published reports. M...
متن کاملPost-carotid endarterectomy cerebral hyperperfusion leading to intracerebral haemorrhage.
A 58 year old hypertensive man experienced several episodes of transient weakness of the left limbs during the year before admission, when neurological examination disclosed a left hemiparesis and spatial hemineglect. T2 weighted brain MRI (figure A) showed frontotemporoinsular cortical hyperintensity on the right. Carotid angiography showed 90% stenosis (arrow) of the right internal carotid ar...
