The effect of cervical carotid ligation on giant intracranial aneurysms

✓ Two patients with giant aneurysms of the internal carotid artery showed progressive visual field deficits, and one, endocrine dysfunction. Neither patient had ever had symptoms suggesting subarachnoid hemorrhage. Both patients benefitted from common carotid ligation. Comparable reports are reviewed, and the application of a previously reported technique for monitoring gradual occlusion of the common carotid artery is emphasized.
