Efficacy of Complex coils in embolization of intracranial lobulated aneurysms: a clinical analysis of 34 cases

Abstract

Objective To evaluate the efficacy of Complex coils as the framing coils on the embolization of intracranial lobulated aneurysms. Methods From April 2017 to April 2018, 34 patients with lobulated aneurysms admitted in our neurosurgery department were enrolled in this study. They all underwent implantation of Complex coils as the framing coils, and their clinical data were collected and retrospectively analyzed. The results of intraoperative cerebral angiography and follow-up outcomes were discussed. Results According to the Raymond standard of aneurysm occlusion, grade Ⅰ occurred in 27 of 34 patients (79.4%), and grade Ⅱ in 5 patients (14.7%), in intraoperative assessment. In the 31 patients who were followed-up through digital subtraction angiography at 6 months after operation, no recurrence was found. In the assessment of aneurysm occlusion, Raymond grade Ⅰ was achieved in 28 patients (90.3%), and Raymond grade Ⅱ in 3 patients (9.7%). No complications associated with Complex coils were observed during perioperative period. Conclusion Complex coils achieves a high success rate as forming frame in the embolization of lobulated aneurysms, with no obvious increase in complications.
