Flow diverter device Tubridge in intracranial complex aneurysms: an efficacy and safety analysis / 中华神经医学杂志

ABSTRACT

Objective:To observe the short-term efficacy and complications of flow diverter device Tubridge in the treatment of complex intracranial aneurysms, and to summarize the indications and experience of Tubridge in treatment of complex intracranial aneurysms.Methods:Thirty-one patients with complex intracranial aneurysms accepted treatment with assistance of Tubridge in our hospital from January 2020 to December 2020 were enrolled. Raymond grading was used to evaluate the degrees of aneurysm embolization immediately after surgery. Modified Rankin scale (mRS) was used to evaluate the prognoses 6 months after surgery. The embolization of aneurysms was determined in these patients by DSA 6 and 12 months after surgery.Results:Thirty-seven aneurysms were noted in these 31 patients. A total of 32 diverters (Turbridge) were implanted into these 37 aneurysms, and all of which were successfully delivered and released. Thirteen aneurysms were filled with spring coils (8 with Raymond grading I, 2 with Raymond grading II, 3 with Raymond grading III by DSA immediately after surgery), and 24 aneurysms were not filled with spring coils. Postoperative ischemic complications occurred in 1 patient, and no hemorrhagic complications or death were noted. All 31 patients had good prognosis at follow-up. Six months after surgery, DSA re-examination in 24 patients (77.4%) showed that complete occlusion of aneurysms was achieved in 17 patients (70.8%). DSA re-examination 12 months after surgery showed complete occlusion of aneurysms in 19 of the 25 patients (76%).Conclusion:The new domestic flow diverter device Tubridge has a high success rate, less perioperative complications, high safety, and good recovery in the treatment of complex intracranial aneurysm.
