Transient adenosine-induced asystole is a reliable method for producing short period of relative hypotension during surgical and endovascular procedures. Although the technique has been described in treatment brain arteriovenous malformations, aortic aneurysms, posterior circulation cerebral little description its use anterior aneurysms available.To assess benefits transient complex to describe our experience selected cases, provide first adenosine aneurysms.The cardiac arrest protocol allows us titrate duration on basis individual patient responses. The operative setup same as with all aneurysm clippings, addition placement transcutaneous pacemakers precaution prolonged bradycardia or asystole. Escalating doses are given determine approximate dose that results 30 seconds When requested by surgeon, administered definitive dissection clipping. We present 6 cases which this was used.The provided excellent circumferential visualization neck safe clip application. All patients did well neurologically suffered no evidence perioperative ischemia delayed complication from itself.Transient effective select circumstances may aid Along traditional techniques relaxation, skull base approaches, temporary clipping, facilitates another available cerebrovascular surgeons.
