Abstract
At the request of the Journal Editor/author(s), with the agreement of the authors/Journal Editor, the following article has been retracted.
Cyrek, A E, Husen, P, Radünz, S, et al: Assessment of Intraoperative Flow Measurement as a Quality Control During Carotid Endarterectomy: A Single-Center Analysis. Scand J Surg, first published online November 9, 2020, DOI: https://doi.org/10.1177/1457496920971139
The Corresponding author notified the Journal Editor and SAGE of the following errors in the article:
The carotid endarterectomy program as described in the manuscript was started under Prof. J.N. Hoffmann’s directorship of the Division of Vascular and Endovascular Surgery. He and other members of his team should have been included as authors on the manuscript.
A typo in the recruitment period, it should be: March 2012- March 2015 and not March 2013- March 2015.
Postoperative vascular duplex ultrasound was not performed by the Division of Vascular and Endovascular Surgery, but by the Department of Neurology. The statement that all patients received the examination within 24 hours was incorrect. The correct statement would be that duplex ultrasound was performed in all patients as soon as the patients’ condition permitted the examination. In fact, only 14% of patients were examined within 24 hours, but 85% were examined within 96 hours.
Furthermore, the correct description of the procedure performed by the neurologists (line 149-150) would be “Also, angle-corrected flow velocity systolic and diastolic in cm/sec was measured and analysed” instead of “Also, volume flow rates were measured three times in each artery, and the mean value was used for this analysis”.
Due to the collection of errors, the article has been retracted. The authors apologise for the honest mistakes.
