Abstract

he main objective of this study was to assess whether Tc-99m-HMPAO brain SPECT imaging can identify patients at high risk of developing an infarct following permanent carotid occlusion in the course of brain surgery. Methods: Test balloon occlusion of the internal carotid arterywas performed in 44 patients with a variety of head and neck tumors or aneurysms. Technetium-99m-HMPAO was injected intravenously while theballoon was inflated and a SPECT study was obtained 30 min later, Follow-up CT scans were obtained routinely for all patients at 2 wk and 1mo following surgery, or earlier when necessary. Thirty patients and five normal volunteers had semiquantitative analysis of cerebral perfusion, Results: Twenty-six patients demonstrated ipsilateral perfusion abnormalities during trial occlusion. Eight patients in this group underwent bypass grafting prior to sacrifice of the artery: two resultingin infarcts, Eighteen patients had symmetric cerebral perfusion during occlusion and four of these patients underwent permanent therapeuticcarotid occlusion; three patients had subsequent infarcts and the fourth patient had an impending stroke, Conclusion: Patients with symmetric cerebral perfusion measured by Tc-99m-HMPAO SPECT may still have a high long-term complication rate following carotid sacrifice, The scanfindings in these patients were not predictive of the outcome. Patients with asymmetric cerebral perfusion had alternative therapeutic approach to carotid sacrifice and most of them had good surgical outcomes.
