Recently, a clinical follow-up study on “stent-assisted embolization of wide neck aneurysms” led by Prof. Xinjian Yang and Dr. Aihua Liu from the Department of Neurointerventional Medicine of our hospital showed that the use of Enterprise stent-assisted embolization of wide neck aneurysms has higher complete embolization rate, lower complication rate and recurrence rate on follow-up review. Domestic and international experimental studies of aneurysms with subarachnoid hemorrhage have shown that the proportion of residual necks is higher in aneurysms embolized with spring coils alone, especially for wide-necked aneurysms, and that the rate of aneurysm re-rupture and recurrence is higher in patients with aneurysms with residual necks than in patients with complete embolization. The recurrence and re-embolization rates after aneurysm embolization still reach 20.8% and 10.3%, and it is more difficult to embolize wide neck aneurysms, and the risk of recurrence after embolization is higher, even up to 30%, which has been a difficult point for neurosurgical open clamping and neurointerventional embolization treatment. From April 2009 to November 2011, Xinjian Yang et al. treated 169 patients (182 wide neck cerebral aneurysms) with a new nickel-titanium alloy memory intracranial special Enterprise stent assisted by spring ring embolization, of which 166 patients (179 wide neck aneurysms) were successfully released, and only 3 cases were unable to reach the lesion due to severe tortuosity of the aneurysm-carrying artery. Immediate postoperative angiography showed complete embolization in 101 aneurysms (56.4%) and near-total tethering in 55 (30.7%). The average follow-up time was 8.1 months in 108 patients who underwent angiographic follow-up. 95 aneurysms (79.8%) were completely tethered and 12 aneurysms (10.1%) were nearly completely tethered. According to Prof. Xinjian Yang, the Enterprise stent has a novel design with four markers at each end and positioning markers on the delivery guidewire, and features good compliance and high rate of placement, especially for the support of vessels larger than 3 mm in diameter, which is more stable and less likely to be displaced. This study initially confirmed that the stent-assisted spring coil embolization has good short-term efficacy in treating wide cerebral carotid aneurysms, and is the safest and most effective new method for treating wide cerebral carotid aneurysms. This study was supported by the National Science and Technology Support Program of the 12th Five-Year Plan, the National Key Basic Research Development Program and the National Natural Science Foundation of China.
