Evaluation of Brain Extracranial-to-Intracranial (EC-IC) Bypass Treatments by Using Computational Hemodynamic Technology

Computational fluid dynamics(CFD) techniques were used to investigate the hemodynamic effect on EC-IC brain bypass. Local hemodynamic factors at the vascular anastomosis sites have long been thought to play an important role in the platelet activation, growth of intimal hyperplasia and thrombosis of brain bypass anastomosis and hence, affecting graft longevity. In this study, the medical imagin...

[Long-term follow-up of EC/IC bypass].

Between 1973 and 1985, superficial temporal artery-middle cerebral artery (STA-MCA) anas tomosis was performed in 125 patients with steno-occlusion of the internal carotid or middle cerebral artery. Patients with moyamoya disease were excluded. One hundred twenty patients were followed for an average of 5.1 years (range, 0 to 12 .5 years). The patients were divided into four groups according to...

The International Cooperative Study of Extracranial/Intracranial Arterial Anastomosis (EC/IC Bypass Study): methodology and entry characteristics. The EC/IC Bypass Study group.

This report summarizes the protocol of a randomized trial of superficial temporal artery-middle cerebral artery (STA-MCA) bypass procedure and presents the entry characteristics of its patients. The trial has been designed to determine whether this EC/IC bypass reduces the rate of subsequent stroke among patients with recent hemispheric or retinal strokes and/or transient ischemic attacks who h...

Can we identify patients with carotid occlusion who would benefit from EC/IC bypass? Review.

Occlusion of the internal carotid artery (CAO) is associated with a high mortality rate and frequent disability in survivors. Even in patients with good clinical recovery there is a high risk of recurrent stroke, mainly in those with impaired cerebral vasomotor reactivity (CVR). Current evidence based therapeutic options for patients with symptomatic CAO include antithrombotic medication and co...
