Abstract

Abstract:

Objective

To investigate the safety and efficacy of domestic Tubridge Flow Diverter in the treatment of vertebral artery dissecting aneurysms (VADA).

Methods

A total of 19 aneurysms in17 VADA patients treated with Tubridge blood flow diverting device in Henan Provincial People's Hospital from April 2018 to July 2020 were retrospectively included. All of them were unruptured aneurysms. The clinical outcomes of the patients were evaluated by modified Rankin Scale (MRS) score.The O'Kelly-Marotta (OKM) scale was used to evaluate aneurysm occlusion during imaging follow-up.

Results

A total of 20 Tubridge Flow Diverter were implanted in 19 aneurysms in 17 patients, including 6 patients combined with coils and 11 patients with stent implantation alone. The success rate of the operation was 100%, and the stents were released successfully and attached well. No perioperative complications occurred. The discharge MRS score was 2 in 1 case, 1 in 4 cases, and 0 in 12 cases.All the 17 patients were followed up with a median follow-up time of 15 (11~20) months. None of the 17 patients had obvious symptoms (mRS 0). Twelve patients were followed up by imaging, with a median follow-up time of 6 (6~8) months. Eight patients had grade D aneurysm OKM, 1 had grade C aneurysm, and 3 had grade B aneurysm.No stent stenosis was observed.

Conclusions

Domestic Tubridge Flow Diverter has a high success rate and good safety in the treatment of vertebral artery dissection aneurysms. Imaging follow-up showed a high rate of complete occlusion.
