ACCUMULATED experiences over the past 15 years have established carotid ligation as one of the suggested treatments for intracranial aneurysms.1-7 It has been estimated that a 20% to 50% drop of late intra-arterial pressure is necessary to induce eventual and complete thrombosis of the aneurysm.6,7 If the thrombosis becomes incomplete, we believe a process of enlargement by lamination could occur.

The pertinent findings at this time were a stiff neck, lethargy, early papilledema, a mild left central facial paresis and left hemiparesis. The cerebrospinal fluid contained blood,
