Tubridge flow diverter for the treatment of recurrent cerebral aneurysms

Abstract

Background & Objective: The Tubridge flow diverter is a commonly used device in China for reconstructing the parental artery and occluding complex intracranial aneurysms. However, there is limited experience with the device in treating recurrent intracranial aneurysms. The purpose of this study is to assess the safety and effectiveness of the Tubridge flow diverter in treating recurrent single- coiling aneurysms. Methods: The clinical records of patients with recurrent intracranial aneurysms who were treated with a Tubridge flow diverter were reviewed to show the therapeutic process, occlusion rate, and clinical outcomes associated with this treatment method. Results: Five patients with recurrent aneurysms of the internal carotid artery after singe coiling were included in the study. The recurrent aneurysmal sac had a mean length and width of 8.34/4.30 mm. All five Tubridge flow diverters were implanted without any unfold failure. The last angiographic follow-up showed a complete occlusion rate of 100%. Five branch arteries were covered, and only one branch artery disappeared during follow-up. No cases of cerebral infarction or intracranial hemorrhage were found among the patients. Conclusions: Our initial findings indicate that the Tubridge flow diverter could be a reliable and successful method for treating recurring single-coil aneurysms. We observed that the branch arteries were well-preserved, and no patients experienced cerebral infarction or hemorrhage. However, further research is necessary to establish clear indications and potential complications through a multicenter randomized controlled trial with long-term follow-up.
