Wide-neck瘤に対するEnterprise VRDを用いたstent assisted coilingの初期成績

摘要: ●Abstract● Object: This report describes our initial experience using a new self-expanding nitinol stent, Enterprise VRD (Cordis, Miami, FL, USA), designed for the treatment of wide-necked intracranial aneurysms. Method: Stent-assisted coiling was performed in 33 saccular aneurysms between July 2011 and December 2012 this institution. Six were recanalized after prior endovascular treatment. The located following arteries: 15 internal carotid artery (ICA; 45.5%), 2 middle cerebral (MCA; 6.1%), 3 anterior communicating (AcomA; 9.1%), 12 basilar (BA; 36.7%), 1 posterior artery(PCA; 3.0%). mean aneurysm dome size 11.6 mm (7-25 mm), neck 6.54 (4-13.8 mm). Patients given 81 mg aspirin 75 clopidogrel daily starting at least 7 days before stent deployment. All stents deployed standard jailing technique. Result: accurately placed all patients. Difficulty navigating Prowler Select Plus microcatheter USA) beyond experienced 5 patients (15.2%). Therefore, catheter exchange these Slip drop during deployment occurred patient. Additional coil embolization immediately achieved patients, occlusion complete 25 (75.8%). However, it necessary to switch from jailed technique trans-cell 8 (24.2%). Procedural adverse events included two thrombo-embolisms one subarachnoid hemorrhage. There 3% morbidity rate no mortality. Follow-up angiography 10 Asymptomatic Conclusion: is valuable its safety efficacy should be further evaluated larger series with longer follow-up. ●Key Words● VRD, assisted coiling,
