Follow-up of 93 patients at 6-13 months indicated 3 cases of aneurysm recurrence. One case of hemorrhage was noted postoperatively. Streak metal artifact removal reconstruction and 2D angiography at working angles showed incomplete deployment of 6 stents and incomplete aneurysm embolization of 15 patients, which were subsequently resolved. 05) with high-resolution C-arm CT combined with streak metal artifact removal reconstruction. Image quality was significantly higher (P <. In total, 118 aneurysms were successfully embolized using 118 stents. Follow-up assessments included clinical and angiographic outcomes and complications. The reconstructed images indicated the stent deployment degree and packing density. Subsequently, the image quality was compared. 3D images were reconstructed with and without streak metal artifact removal techniques. Conventional C-arm CT and high-resolution C-arm CT scanning of the stented area were performed during and after treatment. We evaluated the utility of high-resolution C-arm CT combined with streak metal artifact removal technology for stent-assisted embolization of intracranial aneurysms.įrom October 2017 to July 2018, the First Affiliated Hospital of Zhengzhou University treated 107 patients with intracranial aneurysms (118 aneurysms in total) with stent-assisted embolization. Metal artifacts from coils and stents limit the level of detail in C-arm CT images of stent attachment and coiling attenuation in the aneurysm neck. ![]() The Solitaire AB stent is effective with a good technical success rate and short-term effect for assisting coil embolization of wide-necked cerebral aneurysms. The follow-up spanned 3-37 months of 92 patients examined by DSA at the 6-month follow up, 12 had disease recurrence. ![]() Perioperatively, there were four cases of hemorrhage and four cases of stent thrombosis. DSA immediately post-surgery revealed 55 cases of complete occlusion, 59 cases of neck remnant, and six cases of aneurysm remnant. The 120 Solitaire AB stents (4 mm × 15 mm, four stents 4 mm × 20 mm, 16 stents 6 mm × 20 mm, 36 stents 6 mm × 30 mm, 64 stents) were inserted to treat 120 wide-necked cerebral aneurysms. ![]() We also observed complications to evaluate the safety and effectiveness of this therapy. The degree of aneurysm occlusion was examined using digital subtraction angiography (DSA) immediately after the procedure and during follow-up, and was graded using the modified Raymond classification. ![]() Retrospective review of the clinical and image data of 116 patients with wide-necked cerebral aneurysms who had been enrolled at six interventional neuroradiology centers from February 2010 to February 2014 and had been treated by coil embolization in total, 120 Solitaire AB stents were used. The objective of this study was to evaluate the effectiveness and safety of the Solitaire AB stent in the coil embolization of wide-necked cerebral aneurysms. However, large sample studies on its safety and effectiveness are lacking. The Solitaire AB stent is one of many assistant stents used for treating wide-necked cerebral aneurysm, and has been used since 2003.
