Abstract

The purpose of this paper is to present comparison between classical head computed tomography (CT) and Single Photon Emission CT (SPECT) imaging in patients with internal carotid artery stenosis before and after of endarterectomy. Single Photon Emission CT examinations were performed using gamma camera (Siemens), model DIACOM GANTRY NM, with intravenous application of HMPAO with 99mTc.
Computed tomography examinations were performed using Siemens ART. Slice thickness was 10 mm and 5 mm for posterior fossa imaging. A group of 16 patients was analysed. There were 6 females and 10 males aged 49-71 years (mean 58.5). Six patients had ischemic cerebral stroke and 2 patients had TIA incidents during last 3-10 months before surgical treatment. One patient had asymptomatic stenosis of ICC with pronounced murmur. In all patients stenosis of ICA of 75-85% was seen in doppler examination. Computed tomography examinations performed befor endarterectomy showed changes in 7 cases of stroke. Single Photon Emission CT examinations performed before surgery in all cases showed focal disturbances of cerebral blood flow (reduced uptake or cumulation defect of 99mTc-HMPAO). Examinations repeated after endarterectomy showed improvement of cerebral blood flow with increased marker uptake. Single Photon Emission CT is a successfull method for monitoring cerebral blood flow changes as a result of endarterectomy
