Determinants of success in treating acute ischemic cerebral and ocular ischemia through carotid revascularization. An observational study of a case series.

Objective: stroke etiology is ischemia in 85%, and in circa 25% of these, the source is the extracranial carotid. Recurrence is frequent and usually more severe. Carotid revascularization prevents new ischemic strokes. The sooner the treatment is undertaken, complete recovery chances are greater with less recurrences. But, historically, intervention in the acute setting was catastrophic. Objective: Identify determinants of success when carotid revascularization after a recent cerebral ischemic event is performed.

Materials And Methods: A cohort of 50 subjects underwent carotid revascularization after ischemic symptoms, within a period of 71 months. The currently diagnostic tools were used, and the symptoms stratified by the Rankin scale. The extension of the cerebral lesion and the source location the source of the event was analyzed.

Results: indications were based on the Rankin Scale (R0: 35.4%; R1: 45.8%; R2:18.8% and R3: zero), on the location of the source and the absence of ischemic areas greater than 15mm. An early surgical approach was adopted in all patients. Extreme care was applied to control arterial pressure. At discharge, no additional deficits were observed.

Conclusions: carotid revascularization after ischemic events can be achieved without additional morbidity and no recurrences, using the most appropriate therapy in the shortest time, in patients with Rankin Scale up to 2, absence of intracranial hemorrhage and single or multiple ischemic intracerebral areas, with 15mm or less in their greater dimension.
