Abstract

The FRED device is a new generation flow diverter that is a “stent within a stent.” The Fred Pivotal study for treatment of wide necked intracranial aneurysms is currently ongoing in the US. As part of the study, our center has enrolled 11 patients who have been implanted with the device. Here we describe the current short and long term follow up. Out of 11 patients, there have been no procedural complications. The device has been successfully deployed across the aneurysm neck all 11 times. Clinically, there have been no adverse events. 9 patients have undergone 6 month follow up angiograms. Of these, 7 have total or near total occlusion. 5 have had total occlusion and 2 had small remnants near branch vessels originating at the aneurysm. 1 patient had residual aneurysm that was at the carotid terminus thought to be filling from flow from the anterior cerebral artery which was excluded from the FRED. One patient has residual aneurysm. 5 patients have had one year follow ups and all 4 have had total or near total occlusion. The device offers excellent deliverability and thus far efficacy appears to be comparable to other flow diverter devices.
