Abstract:
Objective To investigate the safety and efficacy of flow-directed devices(flow diverter,FD)in the treatment of intracranial anterior cerebral artery aneurysms(ACAA).Methods The clinical data of 21 patients with ACAA,who were admitted to the Department of Neurointerventional Medicine of the First Affiliated Hospital of Zhengzhou University of China to receive FD treatment between February 2019 and August 2022,were retrospectively analyzed.After the treatment,O'Kelly Marotta(OKM)grading criteria was used to determine the degree of occlusion of the aneurysm,and the modified Rankin Scale(mRS)score was adopted to assess the clinical prognosis(0-2 points being defined as a good prognosis,and 3-5 points being defined as a poor prognosis).Results A total of 24 FD stents were implanted in 24 patients(24 aneurysms in total),and the technical success rate of stent implantation was 100％.During the perioperative period,complications occurred in 2 patients(8.3％),including hemorrhagic event(n=l)and ischemic event(n=l).The mRS score in all the 24 patients was ≤2 points.Follow-up imaging examination showed that OKM grade B was seen in 2 patients(8.3％),grade C in 6 patients(25％),and grade D(complete healing)in 16 patients(66.7％).Conclusion For the treatment of ACAA,the FD stent implantation is a safe and effective method.During the postoperative and the long-term follow-up period,neither serious ischemic or hemorrhagic complications nor neurological complications are observed.
