This is because it controls the bleeding from an unexpected rupture and keeps the sac collapsed during the operation. Such a temporary arterial occlusion, however, involves the risk of a focal ischemia that may lead to permanent postoperative neurological deficits. Therefore, to evaluate the influence of a temporary clipping on the outcome of an operation, a retrospective study of 302 patients who underwent an operation for a ruptured supratentorial aneurysm between 1981 and 1990 has been conducted. This study has revealed the information that follows: 1) Overall outcomes In patients given no temporary clipping, their postoperative activity in daily living (ADL) grade was good in 70.7%, i.e. ADL 1 or 2, whereas only 46.4% of the patients given a temporary clipping achieved a similar ADL. 2) Influence of the preoperative Hunt and Kosnik neurological classification on the outcome Irrespective of whether a temporary clip had been used, patients with a Hunt and Kosnik grade of 1 or 2 made a good recovery, whereas patients with a grade of 4 or 5 did not. The application of a temporary clip in grade 3 patients led to a poor result, whereas in grade 3 patients given no temporary clipping the results were good. This would seem to indicate that Hunt and Kosnik grade 3 rating is a critical factor in consideration whether a temporary clip should be used or not. 3) Influence of the operative timing on the outcome.(ABSTRACT TRUNCATED AT 250 WORDS) | lld:pubmed |
