[Surgical treatment of cerebral aneurysms complicated by vasospasm in the acute period].

The results of clipping of an aneurysm in the acute period of subarachnoid hemorrhage are analysed. It is shown that vascular spasm is an increased risk factor if it involves up to 3-4 and more arterial basal segments and is attended by marked general cerebral and focal neurological symptomatology and gross disorders of cerebral function. Such vascular spasm is unfavourable from the standpoint of prognosis in determining the outcomes of the operation.
