The Orbit Galaxy XTRASOFT Coils: A Multicenter Study of Coil Safety and Efficacy in Both Ruptured and Unruptured Cerebral Aneurysms.

Increase packing density with the use of softer three-dimensional (3D) coils has been indicated in reducing aneurysm recurrence. We are reporting a multicenter initial experience of using the Orbit Galaxy XTRASOFT which is a stretch-resistant, softer 3D coil in both ruptured and unruptured aneurysms. A total of 57 consecutive patients from five high-volume neurointerventional centers were reported where at least one Galaxy XTRASOFT coil was used during a procedure. There were 25 patients with ruptured aneurysm and 32 with elective coiling. The overall complication rate was 3.5%, one patient with nonoperative retroperitoneal hematoma and one patient with intraoperative rupture but with no neurological deficit. The occlusion rate of 90% or greater was achieved in 86% of the cases. The discharge modified Rankin score of 0 or 1 was achieved in 100% of the elective coiling and 65% in the ruptured cases. Early experience with Galaxy XTRASOFT coils for both ruptured and unruptured aneurysms appears to be safe with good aneurysm obliteration and low complication rate.
