Short-term outcome for saccular cerebral aneurysms treated with the Orbit Galaxy Detachable Coil System.
Technological advancement within the field of neuroendovascular therapy may lead to safer and more robust treatment options for patients with lesions traditionally not favorable to coil occlusion. We analyze and report our outcomes with the Orbit Galaxy Detachable Coil System (DePuy Synthes, West Chester, PA, USA) for the treatment of anterior and posterior circulation saccular cerebral aneurysms. Patients treated with Orbit Galaxy coils for primary or recurrent saccular cerebral aneurysms from October 2010 to July 2012 were retrospectively reviewed using medical records, operative reports, and radiographs. Ninety-three patients, 69% unruptured and 31% ruptured, were treated with Orbit Galaxy coils for their anterior (80%) or posterior (20%) circulation saccular cerebral aneurysm. Primary treatment with Orbit Galaxy coils occurred in 84% of patients with an initial 100% occlusion rate of 65% while 16% had Galaxy coils placed into a "secondary" recurrent lesion. The overall incidence of recurrence was 26% with a mean interval of 7 months. Retreatment for recurrence was needed in 20 patients (22%). The mortality rate was 0%. A 2% incidence of rebleed was observed; each was after a secondary treatment. The morbidity of the treatment was low with 1% having a modified Rankin score greater than 3. Primary endovascular treatment of saccular cerebral aneurysms of the anterior and posterior circulation with the Orbit Galaxy Detachable Coil System is safe and effective in the short term.
