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. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018. All rights reserved.
