Abstract:
Objective To explore the application of self-expanding stent and seperable detachable coil for interventional therapy in patients with wide-necked intracranial aneurysm.Methods 32 patients with wide-necked intracranial aneurysm received the interventional therapy by self-expanding stent and seperable detachable coil.After operation,the situation of the aneurysm occluded were observed by DSA immediately and followed up.Results The stents were successfully deployed in the 32 patients.The seperable detachable coils were occluded in the aneurysms in 29 cases.After operation immediately,the DSA showed that the aneurysms in 18 cases were completely occluded by seperable detachable coils,7 cases were 95% occluded,4 cases were 90% occluded.In the other 3 cases,the aneurysms were too small to be filled by seperable detachable coil,the stents were used only.All the parent arteries were no stenosis.18 h after operation,1 case died from multiple hemorrhage caused by thrombasthenia.Follow-up from 3 months to 1 year,DSA re-examination in 21 cases.Compared with the image immediately after operation,the imagings of DSA were no change in 12 cases,residual necks were disappeared in 5 cases and increased in 1 case.In the 3 cases which stents used only,the aneurysms were no development completely in the 2 cases and decreased in 1 case.6～18 months followed up in 26 cases,the rebleeding and cerebral infarction were no occurred.Conclusions The self-expanding stent is very flexible,secure,and effective.It can good support for the wide-necked aneurysms to be occluded by seperable detachable coils and effective promoting the small aneurysms healing.
