Intracranial aneurysm isolation combined with extra-intracranial bypass in treatment of middle cerebral artery aneurysm / 局解手术学杂志

ABSTRACT

Objective To investigate the effect of intracranial aneurysm isolation combined with extra-intracranial bypass in treatment of middle cerebral artery aneurysm.Methods From January 2013 to March 2015,there were 32 patients with complex middle cerebral artery aneurysm in our hospital,who were treated by intracranial aneurysm isolation combined with extra-intracranial bypass.The clinical symptoms and image examination after surgery were retrospectively analyzed,and the hemodynamic index of middle cerebral artery before and after treat-ment was statistically analyzed.Results The postoperative clinical symptoms of 25 patients were relieved,the mRS score was 0 point.Seven patients received surgery,1 week later,the muscle force of involved side was grade 2 to 3,the mRS score was 2 to 3 point,the blood flowing smoothly in target vessel,with no original aneurysm,no new ischemic stroke or infarct.After intervention,systolic and diastolic blood flow ve-locity were faster than those before the intervention(P <0.05),blood flow resistance were lower than those before intervention(P <0.05). Conclusion The intracranial aneurysm isolation combined with extra-intracranial bypass can effectively improve the clinical symptoms of pa-tients with complex intracranial aneurysms,with high graft patency rate and reliable effect.
