Clinical Analysis Of Combining Neuroform3 Stents And Coils For The Treatment Of The Wide-necked Intracrania Aneurysm

Objective: To investigate the therapeutic purposes , the efficacy , the the characteristics and role of the used stent, technical characteristics, the prevention of complications and postoperative care of combining Neuroform stents 3 and Guglielmi detachable coil (GDC) for wide-necked intracranial aneurysms and the trend of the development of treatment of intracranial aneurysms and other issues. the prevention of complications and postoperative handling of combining Neuroform stents 3 and Guglielmi detachable coil (GDC) for wide-necked intracranial aneurysms.Methods: Among 5 cases who were diagnosed with wide-necked intracranial aneurysms by digital subtraction angiography, including three cases of the left internal carotid artery posterior communicating artery wide-necked aneurysms, one case of the left vertebral artery inferior artery wide-necked aneurysms, and one case of the left internal carotid artery bifurcation, wide-necked aneurysms. The shortest diameter of aneurysms is 2.3mm and the longest 8mm.The shortest diameter of the necks of aneurysms is 2.2mm and the longest 8mm. First of all, the necks of the aneurysms were coveraged with Neuroform3 stents, and then the headend of the micro-catheter were inserted into aneurysms through luminas of stents and eventually coils were implanted in 3 cases . Chiefly the microcatheters were inserted into aneurysms, and then the coils were packed, finally the Neuroform3 stents were released for pressing the coils into the aneurysms because of the coils falling into the parent artery or the end of them remaining in the parent artery in 2 cases. The postoperative follow-up was 2 months to 2 years.Results: Three cases of embolism operations are successfully complet- ed. Bleeding again occured in two cases during surgery,the aneurysms were packed and bleeding stopped. No operative complications happen. The aneurysms were packed to not completely in 1 case and partly in 4 cases. However,one case of the left internal carotid artery posterior communi- cating artery aneurysm died of cerebral hernia on the fourth day after operating, due to severe cerebral vasospasm or thrombus, large brain tissue ischemia, cerebral edema serious and severe intracranial hypertension. Patients were with good recovery and without neurologic dysfunction in the remaining four cases of aneurysms. Neither further bleeding nor thrombus was found among the four patients cured through follow-up for 2 months to 2 years. At the same time ,the aneurysms didn't recurred.Conclusion: Combining intracranial stents and GDC for wide-neck- ed intracranial aneurysms is a safe, effective and reliable way. It is worth further promoting clinically and studying deeply.
