Tubridge flow diverter for the treatment of ruptured intracranial aneurysms:clinical analysis of its safety and efficacy / 介入放射学杂志

ABSTRACT

Objective To investigate the efficacy and safety of Tubridge flow diverter(TFD)in the treatment of ruptured intracranial aneurysms.Methods The clinical data of 13 patients with aneurysmal subarachnoid hemorrhage,who received TFD treatment at the First Affiliated Hospital of Zhengzhou University between March 2019 and Jul 2022,were retrospectively collected.The perioperative materials and follow-up results were summarized and analyzed.Results Successful operation was accomplished in all the 13 patients(13 aneurysms in total).TFD and coil embolization were simultaneously performed in 10 patients(simultaneous treatment),spring coil filling followed by selective staged TFD placement was adopted in 2 patients(staged treatment),and pure TFD placement was employed in one patient.The incidence of perioperative complications was 15.4%(2/13),including asymptomatic ischemic event in one patient and extra-ventricular drainage-related postoperative bleeding in another patient,which caused death of the patient.The median follow-up time was 6.5 months,and 83.3%of patients(10/12)completed cerebral angiography reexamination with DSA.OKM grade D(complete occlusion of the aneurysm)was obtained in 8 patients(80%),and OKM grade C(residual aneurysm neck)in 2 patients.Conclusion For ruptured intracranial aneurysms,TFD implantation is a clinically feasible treatment with favorable safety and efficacy.
