Verification of the Availability of Cerulean DD6

Objective: We show our experiences with the use of a 6Fr Cerulean DD6 (Medikit, Tokyo, Japan) catheter and represent the availability of DD6. Methods: Between May 2017 and October 2018, we performed 19 neurointerventional procedures for 17 patients of anterior circulation aneurysms and two neurointerventional procedures for two patients of posterior circulation aneurysms. We validated the results of the procedures with DD6 such as the techniques of coil embolization, the positions of DD6, the related complications, the kickbacks of DD6, and so on. Results: In all cases, we succeeded with the placement of DD6 and there were no related complications and kickbacks of DD6. The positions of DD6 were C3 in six cases, C4 in 8, C5 in 5, V3 in 1, and V4 in 1. Of all procedures, 12 were performed with the balloon assist technique, 5 were with the stent assist technique, and 4 were with the simple technique. Conclusion: Utilizing DD6, the access difficulty of cervical vessels is apparently reduced and the maneuvers of microcatheters can be made much safer and more reliable for neurointerventional procedures.
