Midterm clinical experience with a complex-shaped detachable platinum coil system for the treatment of cerebral aneurysms: Trufill DCS Orbit detachable coil system registry interim results.
OBJECTIVE
To report an interim analysis of the registry data and evaluate the performance of Trufill DCS Orbit coils in terms of the stability of initial aneurysmal occlusion.


METHODS
From May 1, 2004, to February 1, 2006, 291 patients with ruptured or unruptured aneurysms were enrolled in a multiple-center global registry from 37 centers in the United States, Europe, and Latin America to be treated via endovascular embolization with Trufill DCS Orbit detachable platinum coils. Acute and long-term anatomic and clinical data were collected and evaluated.


RESULTS
Initially, complete obliteration was reported in 187 of 300 treated aneurysms (62.3%) for which data were available; one treated aneurysm had no initial occlusion data. At follow-up (<or=1 year), 99 aneurysms were assessed. For 56 aneurysms with initial complete obliteration, 49 (87.5%) remained stable. The overall grade of occlusion of 99 aneurysms remained stable or improved in 81 cases (81.8%). Recanalization was seen in 16.2% of aneurysms (15 cases of coil compaction and one case of aneurysm growth); two aneurysms (2.0%) had coil migration. Five aneurysms (5.1%) underwent repeat treatment.


CONCLUSIONS
The use of Trufill DCS Orbit coils for the endovascular occlusion of aneurysms allowed a favorable rate of initial complete obliteration, high packing density, and aneurysmal stability at follow-up as long as 1 year. Longer-term follow-up is needed to determine the long-term stability of aneurysmal occlusion.
