Long-term results of microsurgical treatment of patients with distal cerebral aneurysms

ABSTRACT. Microsurgical treatment of patients with distal aneurysms (DA) is an significant problem of vascular neurosurgery.

PURPOSE OF THE STUDY. To investigate hospital and long-term results of treatment of patients with DA.

MATERIALS AND METHODS. The analysis of 40 patients with DA was performed retrospectively. The control group included 40 patients with typical localization of aneurysms. In both groups, a standard set of clinical and instrumental studies was performed in accordance with current clinical guidelines. All patients underwent microsurgical aneurysm clipping. In the long-term period, daily activity, dependence on outside help, the level of disability, cognitive impairment, the level of anxiety and depression were assessed.

RESULTS. Most often, 52 % (21) DA were localized in the middle cerebral artery. In patients in the main group, the average severity prevailed during hospitalization, angiospasm developed much less often, but ICH formed more often. There were no significant differences in the level of disability, the level of self-service, as well as the severity of cognitive and mental disorders in the long-term period in patients from the main and control groups.

CONCLUSIONS. Microsurgical treatment of patients with DA is an effective and relatively safe technique associated with favorable long-term treatment outcomes.
