ABSTRACT
13 cases of intracranial Aneurysm were obliterated intracranially with Heifetz clip under Halothane /O2 Deliberate Hypotensive anesthesia. Deliberate hypotension in the surgery of intracranial aneurysm is used to diminish bleeding and render an aneurysmal sac slack to make clipping easy. Herein is presented a review of clinical experience of deliberate hypotension in conjunction with postural drainage. Clinical investigation has shown that this method offers a wider margin of safety. All factors stressed again the needs for careful, adequate and ideal clippage of the neck of aneurysm preferably with the use of Heifetz clip. Deliberate hypotension and adequate clippage of the neck of aneurysm subsequently allowed a favorable clinical result with an operative mortality by 7.7%.
