Early carotid endarterectomy for critical carotid artery stenosis after thrombolysis therapy in acute ischemic stroke in the middle cerebral artery.
BACKGROUND AND PURPOSE Tissue plasminogen activator (tPA) has been shown to be effective for acute ischemic stroke. However, if a high-grade cervical carotid stenosis remains despite tPA therapy, patients are at risk for recurrent stroke. Carotid endarterectomy (CEA) has been shown to be effective in symptomatic patients with high-grade cervical carotid stenosis in reducing the risk of stroke, ...
متن کاملReduced middle cerebral artery velocity during cross-clamp predicts cognitive dysfunction after carotid endarterectomy.
Transcranial Doppler (TCD) is a useful monitor that can be utilized during carotid endarterectomy (CEA). Cognitive dysfunction is a subtler and more common form of neurologic injury than stroke. We aimed to determine whether reduced middle cerebral artery (MCA) mean velocity (MV) predicts cognitive dysfunction and if so, whether a threshold of increased risk of cognitive dysfunction can be iden...
متن کاملSymptomatic carotid artery stenosis: a solvable problem. North American Symptomatic carotid Endarterectomy Trial.
Last year, the first report appeared from the North American Symptomatic Carotid Endarterectomy Trial (NASCET). An editorial in Stroke remarked enthusiastically upon the results. Striking benefit could be attributed to surgery. The positive result applied only to symptomatic patients who had a very tight stenosis. In terms of stroke, this subgroup of patients treated without surgery proved to h...
متن کاملCharacteristics of Ischemic Brain Lesions After Stenting or Endarterectomy for Symptomatic Carotid Artery Stenosis
Carotid artery stenting (CAS) has emerged as an alternative to endarterectomy (CEA) for treatment of atherosclerotic stenosis of the internal carotid artery. The International Carotid Stenting Study (ICSS) was a randomized trial comparing CAS with CEA in patients with symptomatic carotid stenosis. An analysis of short-term outcome data in ICSS revealed a significantly increased risk in the inci...
متن کاملRoutine Shunting is Safe and Reliable for Cerebral Perfusion during Carotid Endarterectomy in Symptomatic Carotid Stenosis
BACKGROUND The purpose of this report is to describe the perioperative outcomes of standard carotid endarterectomy (CEA) with general anesthesia, routine shunting, and tissue patching in symptomatic carotid stenoses. MATERIALS AND METHODS Between October 2007 and July 2011, 22 patients with symptomatic carotid stenosis (male/female, 19/3; mean age, 67.2±9.4 years) underwent a combined total o...
