Application of the hydrocoil in embolization of acute ruptured intracranial aneurysms

Objective To study the application of endovascular treatment of the acute ruptured intracranial aneurysms with the hydrocoil. Methods Fifteen patients ( treatment group ) with 17 acute ruptured intracranial aneurysms were treated with the hydrocoils.In the same period,18 patients (control group) with acute ruptured intracranial aneurysms were treated with the bare platinum coil.Results In treatment group,16 aneurysms received dease embolization,and one aneutysm had subtotal embolization.In control group,11 aneurysms achieved dense embolization,7 aneurysms had subtotal embolization.There was a significant difference between the two groups ( x2 =5.402,P ＜ 0.05 ). After follow-up by DSA from 6 months to 1.5 years,no recurrence was showed in the treatment group,while recurrence occurred in 5 cases in the control group aneurysm,with a significant difference between the two groups ( x2 =5.510,P ＜0.05 ).Conclusion The hydrocoil is an effective therapy for the endovascular treatment of intracranial aneurysms with improving the packing density of intracranial aneurysm embolization and reducing the recurrence rate.
