Summary of personal experience with endovascular treatment of wide neck aneurysms with balloon or stent assistance: Abstract: OBJECTIVE: To retrospectively summarize the treatment experience of 153 cases of wide neck aneurysms treated endovascularly, and to analyze and summarize the efficacy and prognosis of balloon and stent assistance. METHODS: A total of 853 cases of intracranial aneurysms treated endovascularly from 2005 to 2013 were summarized, including 153 cases of wide carotid aneurysms according to the international diagnostic criteria for wide carotid aneurysms (1, absolute diameter of aneurysm greater than 4 mm, or 2, aneurysm to neck ratio less than 1.5). Among them, men, 74 cases, and women, 79 cases. Age, 19-79 years old, mean 50.3 years old. Balloon remodeling technique was applied in 126 cases, stent combined with spring-ring technique in 25 cases, and stent + balloon-assisted spring-ring embolization in 2 cases. In all cases, the Seldinger’s puncture technique of the femoral artery was used, and a 6F guiding catheter was applied to introduce the aneurysm-carrying artery. The microcatheter was introduced into the aneurysm under the pathogram, and the aneurysm was embolized with the aid of balloon or stent with the application of spring ring until the aneurysm was not visualized. Results: 8 cases of intraoperative aneurysm rupture and bleeding, including 7 cases of rupture by balloon remodeling technique and 1 case of rupture by stent combined with spring coil. There was one case of death, and the rest of the patients recovered well. Conclusion: Both balloon remodeling technique and stent combined with spring coil technique are good choices for the treatment of intracranial wide carotid aneurysm, but balloon remodeling technique can avoid long-term postoperative oral antiplatelet drugs and post-stent restenosis, and should be chosen as much as possible for suitable cases.
