Abstract: <br>Objective: To investigate LVIS stent assisted coil embolization of wide-necked aneurysms around the safety and effectiveness of surgical period. <br>Methods: A retrospective analysis of our hospital from January 2017 to April 2019 LVIS stent assisted coil embolization of wide-necked aneurysms perioperative prognosis of 12 patients with 14 wide-necked aneurysms using LVIS stent assisted coil embolization techniques treatment. 2 cases unruptured aneurysms, 10 cases of aneurysm rupture actuator patients with subarachnoid hemorrhage. Embolization treatment of emergency patients prior to administration of aspirin and clopidogrel 300mg each anus, non-acute patients with aspirin and clopidogrel 75mg 100mg orally once a day, at least three days. Conventional surgery vivo heparin. After oral administration of aspirin (100mg / day for 6 months), clopidogrel (75mg / day for 1-3 months). Clinical effect was assessed using the modified Rankin Scale (modified Rankin Scale, mRS): 0 level, no symptoms; 1 stage, symptoms, Accessible; Grade 2 mild disability; 3, moderate disability; grade 4, severe disabled; 5, severe disability; 6, died. 0 ~ 2 genus good prognosis. <br>Results: 12 patients were completely release the stent, 100% success rate. Angiography immediately after embolization showed complete packing (no contrast medium remaining within the aneurysm). Acute thrombotic events occurred during treatment two cases 16.7%, obtained by the microcatheter after injection Ruti Luo tirofiban recanalization, bleeding did not occur. One case of complete contrast to wait for anesthesia during aneurysm rupture bleeding and death. 1 patient died due to acute myocardial infarction. One case of bleeding during angiography, after psychiatric symptoms mRS1 level. The remaining patients prognosis mRS 0 levels. Good prognosis rate was 83.3%. <br>Conclusion: LVIS stent assisted coil embolization of wide-necked aneurysms perioperative period is safe and effective. But still need further follow-up study of its long-term efficacy. <br>Keywords: LVIS bracket, wide-necked intracranial aneurysms, embolization.

Summary:<br>Objective: To investigate the safety and effectiveness of the lvIS stent-assisted spring-ring embolism and the wide-neck aneurysm perither. Methods: Retrospective analysis of the LVIS stent-assisted spring ring embolism wide-neck aneurysm circumference period from January 2017 to April 2019, a total of 12 patients with 14 wide-neck aneurysms were treated with LVIS stent-assisted spring ring embolism technology. Two of the cases were unruptured aneurysms and 10 were patients with subcranial hemorrhage caused by ruptured aneurysms. Patients with embolism are given 300mg of each before embolism treatment, and non-acute patients are given aspirin 100mg and Cridapoire 75mg orally, once daily, for at least three days. Heparinization in the body during surgery. After surgery, oral aspirin (100mg/day, lasting 6 months), clopidogrel (75mg/day, lasts 1-3 months). Clinical outcome assessment using a modified Rankin Scale (mRS): Level 0, no symptoms; Level 1, symptoms, no disability; Level 2, mild disability; Level 3, moderate disability; Level 4, severe disability; Level 5, severe disability; level 6, death.<br>Levels 0 to 2 are good prognosis. Results: 12 stents in this group were fully released, with a technical success rate of 100%. The contrast immediately after the embolism shows a complete filling (no contrast agent residue in the aneurysm). In the course of treatment, 2 cases of acute thrombosis occurred 16.7%, after microcatheter injection of treofban, no bleeding events occurred. 1 case of imaging waiting for the whole hemp process during the rupture of aneurysm bleeding, postoperative death. 1 case died of acute heart attack after surgery. 1 case of ruptured bleeding during imaging, after surgery has the mental symptoms mRS1 level. The rest of the patients had a 0RS 0 prognosis.<br>The prognosis rate was 83.3 per cent. Conclusion: The period of operation of LVIS stent-assisted spring-assisted spring-ring embolism wide-neck aneurysm is safe and effective.<br>However, its long-term efficacy still needs further follow-up research.

Abstract:<br>Objective: To investigate the safety and efficacy of LVIs stent assisted coil embolization for wide necked aneurysms.<br>Methods: the perioperative prognosis of 14 patients with wide necked aneurysms treated by LVIs stent assisted coil embolization from January 2017 to April 2019 was analyzed retrospectively. Among them, 2 were unruptured aneurysms and 10 were subarachnoid hemorrhage caused by ruptured aneurysms. Aspirin and clopidogrel were given 300mg nano anal before embolization in emergency patients, while aspirin 100mg and clopidogrel 75mg were given orally once a day for at least three days in non acute patients. Routine heparinization was performed during operation. After operation, aspirin (100mg / day, lasting for 6 months) and clopidogrel (75mg / day, lasting for 1-3 months) were taken orally. The clinical effect was evaluated by modified Rankin Scale (MRS): grade 0, no symptom; grade 1, symptomatic, no disability; grade 2, mild disability; grade 3, moderate disability; grade 4, severe disability; grade 5, severe disability; grade 6, death. The prognosis of grade 0-2 was good.<br>Results: all 12 stents were completely released, and the success rate was 100%. Immediately after embolization, angiography showed complete occlusion (no residual contrast agent in the aneurysm). In the course of treatment, acute thrombotic events occurred in 2 cases (16.7%), which were recanalized after injecting tirofiban via microcatheter, and no bleeding occurred. One patient died of aneurysm rupture and bleeding after angiography and waiting for general anesthesia. One patient died of acute myocardial infarction. One patient suffered from rupture and bleeding during the course of angiography, and had mental symptoms of MRS1 grade after operation. The prognosis of other patients was grade 0. The good prognosis rate was 83.3%.<br>Conclusion: LVIs stent assisted coil embolization is safe and effective in the perioperative period. But its long-term effect still needs further follow-up study.<br>Key words: LVIs stent, intracranial wide necked aneurysm, embolization.<br>
