[Atheromatous pseudo-occlusive stenosis of the internal carotid].
Pseudo-occlusion of the internal carotid artery is defined as an angiographically occluded but anatomically patent artery. Between january 1980 and december 1990, 14 cases were diagnosed in our institution. Preoperative Doppler examination of the internal carotid artery suggested almost complete thrombosis in 11 patients and occlusion in 3. The angiographic appearance suggested internal carotid occlusion in all but the presence of the slim sign was in favor of a patent artery. All 14 patients underwent surgery. There were no postoperative deaths; one patient presented an ipsilateral TIA post operatively; 3 others presented an ipsilateral TIA after 2, 16 and 30 months respectively. All carotid arteries were found to be patent. The frequency of pseudo-occlusion of the internal carotid artery is probably underestimated. It must be kept in mind whenever an apparently occluded internal carotid continues to be symptomatic. Diagnosis is based on comparative analysis of Doppler examination and angiographic findings. Surgery is indicated whenever doubt persists.
