RÉSUMÉ
Objective To make a further understanding of the curative efficacy of Surpass Streamline flow diversion treatment for intracranial aneurysms.Methods The clinical data of a total of 68 patients with intracranial aneurysm,who received Surpass Streamline flow diverter treatment at the Affiliated Suzhou Hospital of Anhui Medical University of China between January 2020 and January 2022,were retrospectively analyzed.The preoperative and postoperative changes in hemodynamic parameters,and the preoperative and postoperative 3-,6-,and 12-month modified Rankin Scale(mRS)scores were collected.The imaging findings were analyzed,and the status of aneurysm occlusion was determined.Results Compared with the preoperative values,the postoperative blood flow velocity at the WSS and the tumor neck was decreased,while the blood flow velocity of LSA,RRT,tumor carrier artery and M1 on the affected side was increased(P＜0.05),and the blood flow velocity of Ml on the healthy side showed no significant change(P＞0.05).After surgery,the proportion of patients with low-grade mRS score gradually increased with the time passing,and the difference was statistically significant(P＜0.05).The postoperative 6-month and 12-month incidences of in-stent stenosis were 7.35％ and 8.82％ respectively,incidences of aneurysmal complete occlusion were 52.94％and 63.24％ respectively,and the differences were not statistically significant(P＞0.05).Of the 68 patients having been treated with Surpass Streamline flow diverter,4 patients developed ischemic complications,and 2 of the 4 presented with blurred vision and cortical blindness,one patient had limb weakness and one patient had a in-stent thrombus,all of which were effectively relieved after intervention therapy.Conclusion For the treatment of intracranial aneurysms,Surpass Streamline flow diversion treatment has good efficacy,it can improve hemodynamics,besides,it carries high postoperative complete aneurysmal occlusion rate with satisfactory safety.Therefore,this technique is worthy of clinical popularization.(J Intervent Radiol,2024,33:285-288)
RÉSUMÉ
OBJECTIVE: The purpose of this study is to analyze aneurysm morphology and define limitations and feasibility in endovascular Gugliemi detachable coil(GDC) embolization for anterior communicating artery (ACoA) aneurysms. METHODS: From January 2000 through October 2003, 123patients were treated with endovascular coil embolization for ACoA aneurysms. There were 75women and 48men, with a mean age of 63years. All ruptured aneurysms were treated within 15days of rupture. Aneurysm morphology was classified according to neck size and projection of aneurysm dome as follows - A: neck of aneurysm or =4mm) aneurysms are highly related to recanalization of aneurysms. CONCLUSION: Endovascular coil embolization of ACoA aneurysms shows good outcome in our study. Nevertheless, there is a limitation in the endovascular approach to ACoA, even though advanced modern techniques evolve rapidly. Compensatory surgical approach with the endovascular approach is required for successful treatment of ACoA aneurysms.
