Early experience with a temporary bridging device (Comaneci) in the endovascular treatment of ruptured wide neck aneurysms

Background The difficulties in obtaining complete and stable endovascular occlusion are most evident for ruptured aneurysms exhibiting a wide neck and unfavorable geometric features. The aim of our study was to present our experience with the Comaneci temporary bridging device in ruptured wide neck aneurysms. Methods From May to July 2017, 29 ruptured aneurysms underwent endovascular embolization with the Comaneci device. Angiographic and clinical results were retrospectively analyzed. Results 29 ruptured intracranial aneurysms from different locations were included. Successful embolization was achieved in all lesions; complete post-procedure occlusion was seen in 25 (86%) cases. Insufficient embolization or neck remnant was observed in four cases (13.7%). Complications probably related, directly related, or indirectly related to the device occurred in 3.44% of patients (1/29 patients). At least one angiographic follow-up was performed in each of the 29 cases. The 12 month follow-up examination has yet to be done. Conclusion The Comaneci device offers a new promising and reliable technique that can safely support aneurysm coiling occlusion even in a rupture environment. However, long term monitoring of patients treated by this device is mandatory.
