Objectives– To estimate the need for and the costs of carotid Doppler and carotid endarterectomy after stroke or TIA in non-selected hospitalized patients. Material and methods– During 25 months hospitalized patients with stroke or TIA, in whom carotid endarterectomy could be relevant, were examined with carotid Doppler. If a significant stenosis was found, they were further evaluated for surgery. Based on our results, the requirement for future carotid endarterectomy and Doppler screening was estimated, and the costs of the procedures calculated. Results– Among 1351 patients 703 were screened with carotid Doppler. Forty-five had severe (70–99%) stenosis of the relevant carotid artery. Only 3 were operated on. The future costs of screening were estimated under different assumptions. Conclusion– Carotid endarterectomy is expensive due to the large number of patients screened with carotid Doppler per operated patient. A careful clinical selection of patients for screening is necessary.
