Abstract:Objective: To explore the option of the approaches and timing,the curative effect,intraoperative and postoperative treatment of microsurgery and endovascular intervention for intracranial aneurysm.Methods: 246 intracranial aneurysms(including 20 cases of multiple intracranial aneurysms) in a total of 215 cases were analyzed retrospectively.One hundred and twenty-seven intracranial aneurysms in 121 cases underwent microsurgery,while 119 intracranial aneurysms in 104 cases underwent endovascular therapy.Results: All patients evaluated by GOS(Glascow Outcome Scales).Among the 121 cases with microsurgery,104 cases(86.0%) had good recovery,8 cases(6.6%) were moderate disability,6 cases(5.0%) were severe disability,1 case(0.8%) was in vegetative status,and 2 cases(1.6%) dead.Among those 104 cases with endovascular treatment,87 cases(83.7%) had good recovery,7 cases(6.7%) were moderate disability,4 cases(3.8%) were severe disability,1 case(1.0%) was in vegetative status,and 5 cases(4.8%) dead.Three cases(2.9%) were unsuccessful by this means,because of failure in the intubation of micro catheter,but cured with microsurgery treatment afterwards.Conclusions: Both microsurgery and endovascular treatment for intracranial aneurysm are effective treatment.With their own merits and demerits,those two methods should be approached complementarily,Whether to choose microsurgery or endovascular treatment relies on not only the size and position of the aneurysm,but also the experience of the surgeon and the will of patients as well.
