We describe our experience in balloon test occlusion for giant carotid or basilar aneurysms under hypotension. Twenty-four patients underwent balloon test occlusion (BTO) during the year 2008. Only patients showed absence of any neurological deficits after 20 minutes under normal tension then another 20 minutes under hypotension were considered tolerable for occlusion of the parent artery. Of the 24 patients, four (16.67%) had deficits at normal tension and two (8.33%) had deficits at hypotensive phase. None of the 18 (75%) patients who clinically tolerated test occlusion and had parent artery sacrifice show any complication at follow-up period of two years. Two patients with clinical intolerability underwent carotid artery sacrifice after STA-MCA bypass without sequelae. Balloon test occlusion with hypotension is a useful, competent and simple technique in the evaluation of tolerance to parent artery occlusion in case of giant and complex intracranial aneurysms.
