Introduction: Orthopedists face situations in which the radial artery is sacrificed, either for its use as donor of vascularized tissue for coverage of soft tissue defects or in situations where the radial artery is injured. The aim of this study was to determine the morphological and/or functional changes in hand circulation after the radial artery is sacrificed. Methods: A cross-sectional study was conducted based on the review of medical records of 41 patients of both sexes who underwent cardiac revascularization surgery in which a radial artery graft was used. Patients were evaluated using twodimensional and Doppler ultrasound comparing both forearms, index finger pulse oximetry of both hands at rest and after stress, and scintigraphy of both upper limbs at rest and after stress. Statistical evaluation was performed. Results: Only two patients (4.8%) had symptoms of hand claudication during intense activities. Comparative assessment of both hands by pulse oximetry and perfusion scintigraphy yielded no statistically significant difference. There was a statistically significant difference in ultrasound measurement of the diameter of both ulnar arteries. Conclusion: Perfusion of the hand after the sacrifice of the radial artery is not compromised.
