Conference paper


The only adequate treatment for cerebral saccular aneurysms is careful dissection by microsurgical techniques and clipping of the existing or surgically created neck. Dissection can be done more safely in difficult aneurysms when the intraluminal pressure has been lowered, thus avoiding inadvertent rupture of the aneurysm. Elective temporary occlusion of parent arteries is now being increasingly used for this purpose as an alternative to pharmacologically induced systemic arterial hypotension [2, 4, 9]. After subarachnoid hemorrhage (SAH), systemic hypotension can result in cerebral hypoperfusion due to failure of blood flow autoregulation in affected areas. Moreover, aneurysm rupture can occur in spite of systemic hypotension; this can have devastating consequences.
