Objective To summarize the application of endovascular treatment of the acute ruptured intracranial aneurysms with the new Trufill detachable coil system.Methods Thirty five patients with the acute ruptured intracranial aneurysms were treated with DCS or DCS Orbit within 72 hours. Results All 35 cases were successful with compact embolization in 29 aneurysms,95% in 3 aneurysms,90% in 2 aneurysms,80% in 1 anearysm.One case hemorrhaged during operation and 1 case had thrombosis after operation,but with good prognosis of both.One case died of pneurmonia.Thirty cases achieved clinic follow-up 1 to 15 months after operation with only one rebleeing.Sixteen cases achieved DSA follow-up 3 to 12 months after the operation.Partial recurrence of the occluded aneurysm was shown in 1 case.Conclusions Trufill DCS or DCS Orbit is a safe,reliable and effective therapy for the endovascular treatment of intracraranial aneurysms.
