Acute hyperperfusion syndrome complicating EC-IC bypass

The international EC/IC bypass study.

[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...

Acute renal failure complicating cardiopulmonary bypass surgery.

Acute renal failure developed in 24 (5.3%) of 456 children undergoing cardiopulmonary bypass surgery during a 2-year period. It was more common in younger children, in those with complex cardiac lesions, and in those with long overall bypass times. Fourteen (58%) recovered renal function; renal failure was responsible for death in only two. Early vigorous peritoneal dialysis is advocated after ...

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...

Hyperacute intracerebral hemorrhage complicating carotid stenting should be distinguished from hyperperfusion syndrome.

We describe a patient who experienced a fatal ipsilateral basal ganglia hemorrhage within an hour after carotid angioplasty and stent placement. In the few similar cases published there were no prodromata, but hyperacute onset of severe neurologic deterioration corresponding to intracerebral hemorrhage (ICH). Our findings suggest that besides the delayed ICH that is associated with hyperperfusi...
