Different methods of intracranial-extracranial bypass surgery for the treatment of intracranial aneurysms / 中华外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effects and methods of intracranial-extracranial (IC-EC) bypass surgery in the treatment of intracranial aneurysms.</p><p><b>METHODS</b>The clinical material of 9 cases, who performed IC-EC bypass surgery before occlusion of the parental arteries of intracranial aneurysms, was studied retrospectively, especially how to evaluate the co-lateral circulation of the parental arteries and how to select the different methods of IC-EC bypass surgery.</p><p><b>RESULTS</b>The co-lateral circulation in 9 cases was not enough to meet the need of the cerebral blood flow after occlusion of the parental arteries of the aneurysms. Revascularization by different methods of IC-EC bypass surgery and then occlusion of the parental arteries, ischemia in the brain area feeding by occluded parental arteries of the aneurysms did not occurred.</p><p><b>CONCLUSION</b>When the co-lateral circulation of the parental arteries of intracranial aneurysm is not enough, the revascularization by different methods of IC-EC bypass surgery is needed before occlusion of these arteries.</p>
