Popis: Although the indications for carotid endarterectomy (CEA) are clearly defined by major trials, CEA has not been properly implemented in many developing regions, including Northern Africa represented in this study by Upper Egypt. This study was designed to estimate the need for CEA in symptomatic patients with significant internal carotid artery stenosis in Upper Egypt. The estimated needs and actual provision of CEA in Upper Egypt were compared with those of Uusimaa (Finland) and Wessex (England) regions, representing Northern Europe.Incidence rates were derived from a community-based door-to-door survey in Upper Egypt, Oxford Community Stroke Project, and epidemiological Finnish studies. The provision of CEA was derived from the local registry of Vascular Surgery Department, Assiut University Hospitals in Upper Egypt; HUSVASC data registry at Helsinki University Central Hospital, and the published data of the Wessex region. The estimated needs were calculated using previously published proportions of patients eligible for CEA.The population at risk of cerebral ischemic events (or=65 years old) is 4% of the Egyptian population compared with 16% and 15% of the British and Finnish populations, respectively. The incidence of stroke and transient ischemic attack (TIA) is comparable in England and Finland but higher than the Egyptian rates (1.9 per thousand and 2.1 per thousand vs. 1.2 per thousand for stroke; 0.5 per thousand and 0.6 per thousand vs. 0.2 per thousand for TIA, respectively). The ratio of the actual provision of CEA to the estimated need in Wessex and Uusimaa is the same (0.5), whereas it is much lower (0.003) in Upper Egypt.Despite the low incidence of stroke and TIA, there is a huge unmet need for CEA in Upper Egypt. Yet, Wessex and Uusimaa also seemed to be at a suboptimal level compared with the estimated need. If CEA could be offered annually to those 1,650 patients with severe symptomatic ICA stenosis, 275 strokes could be prevented in Upper Egypt in 5-year duration, provided that the operative morbidity and mortality rates are equal to those reported in the large, randomized, controlled trials.
