Coil embolization without assistance of balloon dilation or stenting for treatment of newly ruptured very small intracranial aneurysms / 中华神经医学杂志

ABSTRACT

Objective To investigate the effect of coil embolization without the assistance of balloon dilation or stenting for the treatment of newly ruptured very small intracranial aneurysms.Methods A group of 26 subarachnoid hemorrhage (SAH) patients treated in our hospital from August 2010 to April 2013 were enrolled;a total of 26 very small intraeranial aneurysms were identified.All anemysms were firstly spored by CT angiography or MR angiography,and then,followed by digital subtraction angiography (DSA) or 3D-DSA for determination of operation plans.General anesthesia was applied for all patients.Coil embolization was performed without the assistance of balloon dilation or stenting.All aneurysms were rechecked by DSA at 3 and 12 months after embolization.Results After the coiling procedure,18 aneurysms were completely embolized,3 were close to complete embolizaiton,2 were partly embolized,and 3 aneurysms re-ruptured and then completely embolized.All patients were fully recovered to independent living at discharge.The 12 months post-procedure DSA recheck revealed no changes for the 18 aneurysms with complete embolization,stable blood flow for the 3 with close-to-complete embolization,no re-rupture or re-bleeding for the 2 partly embolized aneurysms,and complete embolization for the 3 aneurysms re-ruptured during the procedure.Conclusion Coil embolization alone without the assistance of balloon dilation or stenting may achieve satisfactory results for the treatment of newly ruptured very small intracranial aneurysms.
